This article is a narrative review that discusses the recommended sample size requirements to design a pilot study to assess the reliability of a questionnaire. A list of various sample size tables that are based on the kappa agreement test, intra-class correlation test and Cronbach’s alpha test has been compiled together. For all calculations, type I error (alpha) was set at a maximum value of 0.05, and power was set at a minimum value of 80.0%. For the kappa agreement test, intra-class correlation test, and Cronbach’s alpha test, the recommended minimum sample size requirement based on the ideal effect sizes shall be at least 15, 22, and 24 subjects respectively. By making allowances for a non-response rate of 20.0%, a minimum sample size of 30 respondents will be sufficient to assess the reliability of the questionnaire. The clear guideline of minimum sample size requirement for the pilot study to assess the reliability of a questionnaire is discussed and this will ease researchers in preparation for the pilot study. This study provides justification for a minimum requirement of a sample size of 30 respondents specifically to test the reliability of a questionnaire.

Success rate of direct pulp capping on permanent teeth using bioactive materials: a systematic review and meta-analysis of randomized clinical trials

AbstractAbstract PDFSupplementary MaterialPubReaderePub

This systematic review and meta-analysis aimed to evaluate the success rate of direct pulp capping (DPC) on permanent teeth, comparing the use of MTA with calcium hydroxide and calcium silicate-based cements. A systematic search was carried out in 4 databases until July 2023. The selection was based on PICOS criteria and only randomized clinical trials were included. The risk of bias was assessed using RoB-2 tool, and meta-analyses were performed using RevMan 5.3 software. The overall quality of evidence was determined using the GRADE tool. Thirteen studies were included. Meta-analyses indicated significantly higher success rate for DPC using MTA compared to calcium hydroxide, while no significant difference was observed between MTA and Biodentine, showing a success rate from 80% to 100% even after 3 years of follow-up. Five studies were classified as having high risk of bias and the GRADE assessment revealed low certainty of evidence. DPC is highly effective for permanent teeth when using MTA or Biodentine. There is a need for future well-designed randomized clinical trials to evaluate the efficacy of DPC using newer bioceramic materials.

AbstractAbstract PDFPubReaderePub

The implementation of imaging methods that enable sensitive and specific observation of anatomical structures has been a constant in the evolution of endodontic therapy. Cone-beam computed tomography (CBCT) enables 3-dimensional (3D) spatial anatomical navigation in the 3 volumetric planes (sagittal, coronal and axial) which translates into great accuracy for the identification of endodontic pathologies/conditions. CBCT interpretation consists of 2 main components: (i) the generation of specific tasks of the image and (ii) the subsequent interpretation report. A systematic and reproducible method to review CBCT scans can improve the accuracy of the interpretation process, translating into greater precision in terms of diagnosis and planning of endodontic clinical procedures. MEDLINE (PubMed), Web of Science, Google Scholar, Embase and Scopus were searched from inception to March 2023. This narrative review addresses the theoretical concepts, elements of interpretation and applications of the CBCT scan in endodontics. In addition, the contents and rationale for reporting 3D endodontic imaging are discussed.

Mohamad Adam Bujang
Restor Dent Endod 2024;49(2):e21.   Published online May 2, 2024
DOI: https://doi.org/10.5395/rde.2024.49.e21
AbstractAbstract PDFPubReaderePub
Objectives

This paper aims to serve as a useful guide for sample size determination for various correlation analyses that are based on effect sizes and confidence interval width.

Materials and Methods

Sample size determinations are calculated for Pearson’s correlation, Spearman’s rank correlation, and Kendall’s Tau-b correlation. Examples of sample size statements and their justification are also included.

Results

Using the same effect sizes, there are differences between the sample size determination of the 3 statistical tests. Based on an empirical calculation, a minimum sample size of 149 is usually adequate for performing both parametric and non-parametric correlation analysis to determine at least a moderate to an excellent degree of correlation with acceptable confidence interval width.

Conclusions

Determining data assumption(s) is one of the challenges to offering a valid technique to estimate the required sample size for correlation analyses. Sample size tables are provided and these will help researchers to estimate a minimum sample size requirement based on correlation analyses.

Fracture resistance and failure modes of endodontically-treated permanent teeth restored with Ribbond posts vs other post systems: a systematic review and meta-analysis of in vitro studies
Meghana Aditya Vartak, Vibha Rahul Hegde, Sanitra Rahul Hegde, Ushaina Fanibunda
Restor Dent Endod 2025;50(1):e5.   Published online February 17, 2025
DOI: https://doi.org/10.5395/rde.2025.50.e5
AbstractAbstract PDFPubReaderePub
Objectives
This systematic review aimed to investigate the fracture resistance and mode of failure of endodontically-treated permanent teeth restored with Ribbond posts (Ribbond, Inc.) compared with endodontically-treated permanent teeth restored with other post systems.
Methods
A comprehensive, systematic literature search was carried out using several electronic databases: MEDLINE/PubMed, Google Scholar, and Cochrane Library. Two separate researchers were appointed to identify the studies meeting the eligibility criteria, and to perform the data extraction, risk of bias, and quality assessment.
Results
Twelve studies were included in the quantitative analysis. Meta-analysis was performed with 11 of the 12 included articles. The meta-analysis showed that Ribbond posts have a fracture strength less than prefabricated metal posts, cast metal posts, and prefabricated fiber posts and greater than custom e-glass fiber posts. Mode of failure analysis revealed that Ribbond posts have the most favorable non-catastrophic fractures.
Conclusions
Although Ribbond posts have lower fracture resistance, their favorable mode of failure makes them potentially the most biomimetic post system.

Effect of quality of radiographs taken during root canal treatment on technical quality of root canal fillings and endodontic outcome
Jia Min Ng, Yan Yee Lee, Prashanti Chippagiri, Elaheh Ahanin, Abhishek Parolia
Restor Dent Endod 2025;50(1):e3.   Published online January 7, 2025
DOI: https://doi.org/10.5395/rde.2025.50.e3
AbstractAbstract PDFPubReaderePub
Objectives
This study evaluated the number and quality of working length (WL) and master cone (MC) radiographs taken during root canal treatment by dental undergraduates, and their associations with the technical quality of root canal fillings (TQRCF) and endodontic outcomes (EO).
Methods
A retrospective evaluation of radiographs from 303 root canal-treated teeth in 231 patients was conducted, with 72 patients attending recall visits to assess EO. The chi-square and one-way analysis of variance tests were performed.
Results
A total of 505 WL and 557 MC radiographs were reviewed, with 72.9% and 75% deemed satisfactory, respectively. Satisfactory TQRCF was achieved in 60.4% of cases. Significant associations were found between the extension of the file in WL and gutta-percha in MC radiographs and TQRCF (p = 0.000). Misinterpretation of these radiographs resulted in poor TQRCF. Furthermore, 64.2% of teeth had satisfactory EO. A significant relationship was noted between the quality of MC radiographs and both TQRCF (p = 0.043) and EO (p = 0.003).
Conclusions
Unsatisfactory MC radiographs were linked to poor TQRCF and unfavorable EO. Regular radiographic training is recommended to enhance EO.

Can carbamide peroxide be as effective as hydrogen peroxide for in-office tooth bleaching and cause less sensitivity? A systematic review
Patrick Wesley Marques de Boa, Kaiza de Sousa Santos, Francisca Jennifer Duarte de Oliveira, Boniek Castillo Dutra Borges
Restor Dent Endod 2024;49(2):e14.   Published online March 20, 2024
DOI: https://doi.org/10.5395/rde.2024.49.e14
AbstractAbstract PDFPubReaderePub

This study aimed to answer the question through a systematic review: Can carbamide peroxide be as effective as hydrogen peroxide and cause less in-office bleaching sensitivity? A literature survey was performed in PubMed/MEDLINE, Embase, Scopus, ISI Web of Science, and gray literature. Primary clinical trials that compared the efficacy or the in-office bleaching sensitivity between carbamide and hydrogen peroxides were included. The risk of bias was evaluated using the RoB2. The certainty of the evidence was assessed using the GRADE approach. DPI training significantly improved the mean scores of the dental undergraduates from 7.53 in the pre-DPI-training test to 9.01 in the post-DPI-training test (p < 0.001). After 6 weeks, the mean scores decreased marginally to 8.87 in the retention test (p = 0.563). DPI training increased their confidence level from 5.68 pre-DPI training to 7.09 post-DPI training. The limited evidence suggests that the 37% carbamide peroxide may be similarly effective to the 35% hydrogen peroxide for bleaching teeth in-office and causes less bleaching sensitivity. However, more well-designed split-mouth clinical trials are necessary to strengthen the evidence.

Effect of surface treatment on glass ionomers in sandwich restorations: a systematic review and meta-analysis of laboratory studies
Hoda S. Ismail, Ashraf Ibrahim Ali, Franklin Garcia-Godoy
Restor Dent Endod 2025;50(2):e13.   Published online April 16, 2025
DOI: https://doi.org/10.5395/rde.2025.50.e13
AbstractAbstract PDFPubReaderePub
Objectives
This study aimed to evaluate the effect of different surface treatments on the bond strength between new or aged glass ionomers (GI) and resin composites in sandwich restorations.
Methods
A comprehensive search was conducted in three databases to identify studies focusing on the bond strength of new or aged GIs and resin composites in laboratory settings. The selected studies were assessed for potential biases based on predetermined criteria. Additionally, a meta-analysis was performed using three studies.
Results
A total of 29 studies were included, with 24 investigating the bond strength of new GIs and five focusing on GI repair. Three studies were included in the meta-analysis (with a 95% confidence interval) which revealed no significant difference in the mean MPa values of resin-modified glass ionomer (RMGI) treated with phosphoric acid or Er,Cr:YSGG laser before the application of an etch-and-rinse adhesive. Surface treatment was found to be crucial for achieving optimal bonding between GI and resin composite, regardless of the GI’s condition.
Conclusions
The combination of mechanical and chemical surface treatments does not significantly affect the bond strength between new RMGI and composite. However, for GI repair, it is recommended to use both treatments to enhance the bond strength.

AbstractAbstract PDFSupplementary MaterialPubReaderePub
Objectives
While the success criteria of endodontic microsurgery (EMS) have been consistently defined and widely accepted, the success criteria of dental implants are outdated and focus only on the implant fixture and surrounding bone. This study aimed to evaluate the outcomes of EMS and single implants (SIs) with explicit criteria.
Methods
We searched for articles published from January 2010 to February 2022 and discussed them and consulted with a clinical advisory committee composed of four dental specialists and one epidemiologist during article selection and data extraction.
Results
Twenty-two EMS studies and six SI studies were included in the meta-analysis. Teeth treated using EMS had a pooled success rate of 89% (90% at <5-year follow-up and 80% at ≥5-year follow-up) and the pooled success rate of SI was 78%.
Conclusions
The success rates of the two procedures with similar follow-up periods were comparable. Subgroup analysis found no other variable that significantly influenced study heterogeneity. Considering the treatment sequence and the similar success rates, it would be advantageous to consider EMS, rather than implants, first in a situation where both procedures are applicable.

Restor Dent Endod 2025;50(1):e7.   Published online February 19, 2025
DOI: https://doi.org/10.5395/rde.2025.50.e7
AbstractAbstract PDFPubReaderePub
Objectives
This study aimed to assess the pattern of endodontic instrument separation, their retrievability, and factors affecting its retrieval, in a postgraduate institute.
Methods
Cases referred for the management of separated endodontic instruments (SEI) from 2013 to 2023 were considered for this study. Data related to demographics, tooth type, file type, and retrieval were documented in an Excel sheet. Eight prognostic factors assumed to influence the retrieval were analyzed in this study. The secondary aim was to compare the pattern of SEI and retrievability between conventional nickel-titanium files and newer generation heat-treated nickel-titanium files. Retrieval was attempted by a senior endodontist under the dental operating microscope. Various ultrasonic tips and a Broken Tool Removal loop system were used during retrieval. Simple descriptive statistics were performed. Binomial logistic regression was done to identify the effect of the eight prognostic factors on the retrieval outcome.
Results
A total of 190 SEI was reported. SEI occurred more often in posterior teeth than anterior teeth, mandibular arch than maxillary arch, and in larger files than smaller files. Separation occurred more often in the apical third compared to the other levels. Retrieval was attempted in 88 cases and successful in 70 cases (79.5%). The larger taper and apical position of the SEI negatively influenced the retrieval by 1.4 and 8.7 times, respectively.
Conclusions
Retrieval of SEI was successful in the majority of the cases. An increase in taper and apically placed SEI negatively impacted the retrieval. There was no difference in the pattern of separation nor retrievability between conventional nickel-titanium files and newer generation heat-treated nickel-titanium files.

AbstractAbstract PDFPubReaderePub

Chronic osteomyelitis with proliferative periostitis, known as Garre’s osteomyelitis, is a type of osteomyelitis characterized by a distinctive gross thickening of the periosteum of bones. Peripheral reactive bone formation can be caused by mild irritation or infection. Garre’s osteomyelitis is usually diagnosed in children and young adults, and the mandible is more affected than the maxilla. The following is a case report of a 12-year-old female patient with Garre’s osteomyelitis of the mandible due to an infection of a root canal-treated tooth. Without surgical intervention, the patient’s symptoms were relieved through nonsurgical root canal re-treatment with long-term calcium hydroxide placement. A cone-beam computed tomography image obtained 6 months after treatment completion displayed complete healing of the periapical lesion and resolution of the peripheral reactive buccal bone. Due to the clinical features of Garre's osteomyelitis, which is characterized by thickening of the periosteum, it can be mistaken for other diseases such as fibrous dysplasia. It is important to correctly diagnose Garre's osteomyelitis based on its distinctive clinical features to avoid unnecessary surgical intervention, and it can lead to minimally invasive treatment options.

Objectives

This study aimed to establish a single-session associative protocol for non-restorative management of dentin hypersensitivity (DH).

Materials and Methods

Twenty-four individuals with DH and a minimum sensitivity level of 4 on the visual analog scale (VAS) were selected. The study was conducted in a split-mouth design, with each participant (n = 20) having at least 1 affected tooth in all quadrants. The management protocols consisted of control group: universal adhesive, Neural Desensitizing Protocol group: 5% potassium nitrate, Mixed Desensitizing Protocol (PAM) group: 5% sodium fluoride and 5% potassium nitrate, Remineralizing Desensitizing Protocol (PDR) group: surface-partially reacted glass technology photopolymerizable varnish. Evaluations were performed immediately after application, at 1 week, 1 month, 2 months, and 12 months using the VAS sensitivity test.

Results

The scores were subjected to statistical analysis using the Friedman test (p < 0.05), Durbin-Conover test (p < 0.05), and Wilcoxon test (p < 0.05). At the 12-month evaluation, all groups showed statistically significant differences compared to the initial assessment. For the evaluation after 12 months, there was a statistically significant difference between the PAM group, the control group, and the PDR group.

Conclusions

It can be concluded that all groups were effective in controlling DH, but there were significant results in the control group and PDR group. The clinical relevance of this study is to demonstrate that the application of single-session desensitizing protocols can be effective in controlling DH for up to 12 months.

The clinical success of ART restorations and Hall technique in primary molars: a randomized 18-month follow-up study
Esra Oz, Zuhal Kırzıoglu, Canan Kale
Restor Dent Endod 2023;48(2):e19.   Published online May 1, 2023
DOI: https://doi.org/10.5395/rde.2023.48.e19
AbstractAbstract PDFPubReaderePub
Objectives

The aim of the study was to evaluate the clinical and radiographic success of the Hall technique (HT) and atraumatic restorative treatment (ART) restorations using high-viscosity glass-ionomer cement for the management of occlusal carious lesions in primary molars.

Materials and Methods

This randomized clinical study observed 40 children (aged 5–6 years). For each child, one tooth was treated with HT and one with ART. The primary outcome measures for HT restorations were successful, minor, and major failure rates. Clinical evaluations of ART restorations were performed according to the modified United States Public Health Service criteria during 18-month follow-up. McNemar test was used for statistical analysis.

Results

Thirty of 40 (75%) participants returned for 18 months of follow-up. In the clinical evaluations of teeth that were treated with HT, the patients did not have complaints of pain or other symptoms, all crowns remained in the oral cavity, the gums were healthy, and the teeth were functional in all evaluations. At the end of the 18-month follow-up, the surface texture and marginal integrity criteria of ART restorations were recorded as 26.7% and 33.3%, respectively. In the radiographic evaluation of 30 patients treated with ART and HT, all restorations were considered successful.

Conclusions

The 18-month clinical and radiographic results after treatments applied to single-surface cavities in anxious children showed that both treatment methods were successful.

Massimo Pisano, Alfredo Iandolo, Dina Abdellatif, Andrea Chiacchio, Marzio Galdi, Stefano Martina
Restor Dent Endod 2024;49(4):e33.   Published online September 5, 2024
DOI: https://doi.org/10.5395/rde.2024.49.e33
AbstractAbstract PDFPubReaderePub
Objectives

The aim of this study was to compare the effects of different polymerization strategies and the effectiveness of finishing and polishing procedures of composite resins on color stability.

Materials and Methods

The samples were divided into 4 main groups according to the polymerization strategy, and all groups except the control group received surface treatment. Each group was subsequently divided into 3 subgroups respectively: Kuraray Clearfil Majesty ES-2 Classic, Premium and Universal. Approximately 24 hours after preparation of the samples, they were immersed for 7 days in a coffee solution. A first color measurement was performed after the preparation of the samples, the second measurement was performed after 7 days in the coffee solution. All measurements were carried out using a dental spectrophotometer to assess the CIE L* a* b* color parameters.

Results

There was a statistically significant difference between ΔE values for different procedures (p = 0.003); in particular, the differences were found only between the groups that received surface treatment and the control group. In addition, a statistically significant difference was observed between the values of ΔE for different composites in the different procedure groups.

Conclusions

Spectrophotometric analysis showed that the additional photopolymerization and oxygen inhibition procedures did not yield better results in relation to color stability. In addition, finishing and polishing provided better color stability compared to not performing these procedures.

Effect of endodontic sealer on postoperative pain: a network meta-analysis
Cynthia Maria Chaves Monteiro, Ana Cristina Rodrigues Martins, Alessandra Reis, Juliana Larocca de Geus
Restor Dent Endod 2023;48(1):e5.   Published online December 29, 2022
DOI: https://doi.org/10.5395/rde.2023.48.e5
AbstractAbstract PDFPubReaderePub

This systematic review and network meta-analysis aimed to answer the following focused research question: “Does the type of endodontic sealer affect the postoperative pain in patients who received endodontic treatment?” Different databases and grey literature were surveyed. Only one randomized controlled trial were included. The risk of bias in the studies was evaluated by using the Cochrane Collaboration’s tool. A random-effects meta-analysis was conducted to compare the risk and intensity of postoperative pain. The quality of the body of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. Out of 11,601 studies, 15 remained for qualitative analyses and 12 for meta-analysis. Seven studies were classified at high risk of bias, and 8 studies raised some concerns. No significant differences between the endodontic materials were observed in the direct comparisons, both in risk and in intensity of postoperative pain (pairwise comparisons with 2 studies: I2 = 0%; p > 0.05 and 8 studies: I2 = 23%; p > 0.05, respectively). The certainty of the evidence was graded as low or moderate. There was no difference in the risk and intensity of postoperative pain after filling with different endodontic sealers. Further systematic reviews should be conducted.

AbstractAbstract PDFSupplementary MaterialPubReaderePub

This study aimed to compare the disinfectant ability of chlorhexidine (CHX) gel and sodium hypochlorite (NaOCl). Systematic searches were conducted from inception until December 8th, 2022 (MEDLINE/PubMed, Cochrane Library, Web of Science, Scopus, Embase, and Grey Literature databases). Only randomized clinical trials were included. The revised Cochrane risk of bias tools for randomized trials were used to assess the quality of studies. Meta-analyses were performed. The overall quality of evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation tool. Six studies were included. Five had a low risk of bias and 1 had some concerns. Three studies assessed bacterial reduction. Two were included in the meta-analysis for bacterial reduction (mean difference, 75.03 [confidence interval, CI, −271.15, 421.22], p = 0.67; I2 = 74%); and 3 in the meta-analysis for cultivable bacteria after chemomechanical preparation (odds ratio, 1.03 [CI, 0.20, 5.31], P = 0.98; I2 = 49%). Five studies assessed endotoxin reduction. Three were included in a meta-analysis (mean difference, 20.59 [CI, −36.41, 77.59], p = 0.48; I2 = 74%). There seems to be no difference in the disinfectant ability of CHX gel and NaOCl, but further research is necessary.

AbstractAbstract PDFSupplementary MaterialPubReaderePub

This study aimed to identify and analyze articles on enamel microabrasion for the treatment of white spot lesions. A search was conducted on the Web of Science. The following parameters were recorded and analyzed: number of citations, year, journal, impact factor, study design, theme, country and continent, institution, authors, and keywords. Data was analyzed using VOSviewer software. The initial search resulted in 1,126 documents, of which 94 articles were included. The highest number of citations an article received was 65. The oldest article was published in 1975, and the most recent in 2023. The most frequent study design was case report (n = 42). Regarding the themes, it was observed that the main objective of the studies was to evaluate the clinical performance of enamel microabrasion (n = 75), primarily using Opalustre (Ultradent Products Inc., South Jordan, UT, USA) (n = 37) for treating white stains caused by dental fluorosis (n = 41). Most articles originated from Latin America (n = 31), mainly from Brazil (n = 26). The most frequent author was Sundfeld RH (n = 10). This study reveals research trends in the field of enamel microabrasion. The publications were mainly case reports/series using Opalustre for the removal of fluorosis stains.

Effects of a relined fiberglass post with conventional and self-adhesive resin cement
Wilton Lima dos Santos Junior, Marina Rodrigues Santi, Rodrigo Barros Esteves Lins, Luís Roberto Marcondes Martins
Restor Dent Endod 2024;49(2):e18.   Published online March 27, 2024
DOI: https://doi.org/10.5395/rde.2024.49.e18
AbstractAbstract PDFPubReaderePub
Objectives

This study was conducted to evaluate the mechanical properties of relined and non-relined fiberglass posts when cemented to root canal dentin using a conventional dual-cure resin cement or a self-adhesive resin cement.

Materials and Methods

Two types of resin cements were utilized: conventional and self-adhesive. Additionally, 2 cementation protocols were employed, involving relined and non-relined fiberglass posts. In total, 72 bovine incisors were cemented and subjected to push-out bond strength testing (n = 10) followed by failure mode analysis. The cross-sectional microhardness (n = 5) was assessed along the root canal, and interface analyses (n = 3) were conducted using scanning electron microscopy (SEM). Data from the push-out bond strength and cross-sectional microhardness tests were analyzed via 3-way analysis of variance and the Bonferroni post-hoc test (α = 0.05).

Results

For non-relined fiberglass posts, conventional resin cement exhibited higher push-out bond strength than self-adhesive cement. Relined fiberglass posts yielded comparable results between the resin cements. Type II failure was the most common failure mode for both resin cements, regardless of cementation protocol. The use of relined fiberglass posts improved the cross-sectional microhardness values for both cements. SEM images revealed voids and bubbles in the incisors with non-relined fiberglass posts.

Conclusions

Mechanical properties were impacted by the cementation protocol. Relined fiberglass posts presented the highest push-out bond strength and cross-sectional microhardness values, regardless of the resin cement used (conventional dual-cure or self-adhesive). Conversely, for non-relined fiberglass posts, the conventional dual-cure resin cement yielded superior results to the self-adhesive resin cement.

AbstractAbstract PDFPubReaderePub

This review aimed to evaluate and compare the biological response (biocompatibility and cytotoxicity) of resin modified glass ionomer cement (RMGIC) in contrast to conventional glass ionomer cement (GIC) on human cells. Articles reporting parallel and split-mouth clinical trials, randomized controlled trials, non-randomized controlled trials, prospective studies, and in vitro studies on human permanent teeth that assessed the biological response of GIC and RMGIC were included. The following electronic bibliographic databases were searched using the keywords: MEDLINE/PubMed, EBSCO, Cochrane Central Register of Controlled Trials, and Google Scholar. For the risk of bias MINORS tool and the modified scale of Animal Research: Reporting of In Vivo Experiments and Consolidated Standards of Reporting Trials were used. Initial screening identified 552 studies, of which 9 articles met the inclusion criteria and were included in the study. Different parameters such as odontoblastic changes, inflammatory response, tertiary dentin formation, presence of microorganisms, morphological changes, cell viability, number, and metabolism were used to evaluate the biological response of conventional GIC and RMGICs. Conventional GIC shows lower cytotoxicity compared to RMGIC in vital pulp therapy procedures. Further, in vivo studies and long-term clinical trials are needed to compare these observations for pulp therapy using the 2 test materials.

AbstractAbstract PDFPubReaderePub
Objectives

This study aimed to evaluate the surrounding and underlying shades’ effect on the color adjustment potential (CAP) of a single-shade composite used in a thin layer.

Materials and Methods

Cylinder specimens (1.0 mm thick) were built with the Vittra APS Unique composite, surrounded (dual specimens) or not (simple specimens) by a control composite (shade A1, A2, or A3). Simple specimens were also built only with the control composites. Each specimen’s color was measured against white and black backgrounds or the simple control specimens with a spectrophotometer (CIELAB system). The whiteness index for dentistry (WID) and translucency parameters (TP00) were calculated for simple specimens. Differences (ΔE00) in color between the simple/dual specimens and the controls were calculated. The CAP was calculated based on the ratios between data from simple and dual specimens.

Results

The Vittra APS Unique composite showed higher WID and TP00 values than the controls. The highest values of ΔE00 were observed among simple specimens. The color measurements of Vittra APS Unique (simple or dual) against the control specimens presented the lowest color differences. Only surrounding the single-shade composite with a shaded composite barely impacted the ΔE00. The highest CAP values were obtained using a shaded composite under simple or dual specimens.

Conclusions

The CAP of Vittra APS Unique was strongly affected by the underlying shade, while surrounding this composite with a shaded one barely affected its color adjustment.

Radiographic patterns of periosteal bone reactions associated with endodontic lesions
Poorya Jalali, Jessica Riccobono, Robert A. Augsburger, Mehrnaz Tahmasbi-Arashlow
Restor Dent Endod 2023;48(3):e23.   Published online June 8, 2023
DOI: https://doi.org/10.5395/rde.2023.48.e23
AbstractAbstract PDFPubReaderePub
Objectives

The formation of new bone by periosteum due to an insult is called periosteal bone reaction (PBR). This study assessed the cone beam computed tomography (CBCT) patterns of periosteal bone reactions associated with periapical inflammatory lesion (apical periodontitis/periapical rarefying osteitis).

Materials and Methods

Twenty-two small field of view CBCT images of patients with PBR were selected from a database of a private practice limited to endodontics. The volume of the periapical inflammatory lesion, the presence of cortical fenestration, the distance of the root apices to the affected cortex, and the location, pattern, and longest diameter of the periosteal reaction were recorded. Statistical analysis was performed using Wilcoxon Ranksum, Fischer’s exact, Spearman Correlation Coefficient, and paired t-test.

Results

In all cases, periosteal bone reaction manifested as either parallel (90.9%) or irregular (9.1%). No correlation was found between periapical inflammatory lesion volume and the periosteal reaction's longest diameter (p > 0.05). Cortical fenestration was noted in 72.7% of the cases. In addition, the findings showed that periosteal reactions were located mostly on the buccal and were present 53.8% and 100% of the time in the mandible and maxilla, respectively.

Conclusions

The periosteal reactions of endodontic origin had a nonaggressive form (i.e., parallel or irregular), and none of the lesions resulted in a periosteal reaction with an ominous Codman’s triangle or spicule pattern.

AbstractAbstract PDFPubReaderePub
Objectives
This study investigated the effects of different whitening toothpaste (WT) on the surface properties and staining susceptibility of a resin composite.
Methods
Cylindrical samples were prepared with a micro-hybrid resin composite and were randomized into groups according to the toothpaste (n = 12): distilled water (DW), regular toothpaste (RT), WT with silica + pyrophosphate (WT-S/P), WT with pentaphosphate and pyrophosphate (WT-P/P), WT with hydrogen peroxide and pyrophosphate (WT-HP/P) and WT with charcoal and pyrophosphate (WT-Ch/P). The samples were brushed for 825 cycles in an automatic brushing machine, simulating 30 days of brushing. After that, an immersion in coffee (10 mL/sample) was performed for 30 minutes for 30 days. The analyses of color, surface microhardness (SMH), and surface roughness (Ra) were performed at the initial time, after brushing with toothpaste and after immersion in coffee. The ΔL*, Δa*, Δb*, ΔEab, Δand E00 values were calculated comparing after toothpaste with initial time and after coffee with after toothpaste. Data were analyzed using a mixed linear model for repeated measures (SMH), Kruskal-Wallis, Dunn, Friedman, and Nemenyi tests, with α = 0.05.
Results
For ΔL*, the WT-Ch/P group had the lowest values and differed from the other groups comparing the after toothpaste with the initial time interval (p < 0.001). The WT-Ch/P group had the lowest SMH values in after-toothpaste time (p < 0.001). In after-toothpaste time and after coffee time, the WT-S/P group had the highest Ra values and differed from the groups except the WT-Ch/P group (p < 0.001).
Conclusions
The toothpaste composition affects the surface characteristics and susceptibility to staining of the resin composite. The charcoal-based toothpaste had the worst performance for the color analyses and SMH.

Stem cell-derived exosomes for dentin-pulp complex regeneration: a mini-review
Dina A. Hammouda, Alaa M Mansour, Mahmoud A. Saeed, Ahmed R. Zaher, Mohammed E. Grawish
Restor Dent Endod 2023;48(2):e20.   Published online May 3, 2023
DOI: https://doi.org/10.5395/rde.2023.48.e20
AbstractAbstract PDFPubReaderePub

This mini-review was conducted to present an overview of the use of exosomes in regenerating the dentin-pulp complex (DPC). The PubMed and Scopus databases were searched for relevant articles published between January 1, 2013 and January 1, 2023. The findings of basic in vitro studies indicated that exosomes enhance the proliferation and migration of mesenchymal cells, as human dental pulp stem cells, via mitogen-activated protein kinases and Wingless-Int signaling pathways. In addition, they possess proangiogenic potential and contribute to neovascularization and capillary tube formation by promoting endothelial cell proliferation and migration of human umbilical vein endothelial cells. Likewise, they regulate the migration and differentiation of Schwann cells, facilitate the conversion of M1 pro-inflammatory macrophages to M2 anti-inflammatory phenotypes, and mediate immune suppression as they promote regulatory T cell conversion. Basic in vivo studies have indicated that exosomes triggered the regeneration of dentin-pulp–like tissue, and exosomes isolated under odontogenic circumstances are particularly strong inducers of tissue regeneration and stem cell differentiation. Exosomes are a promising regenerative tool for DPC in cases of small pulp exposure or for whole-pulp tissue regeneration.

Restor Dent Endod 2024;49(2):e16.   Published online March 22, 2024
DOI: https://doi.org/10.5395/rde.2024.49.e16
AbstractAbstract PDFPubReaderePub
Objectives

This cross-sectional study evaluated the prevalence of apical periodontitis (AP) and the technical quality of root canal fillings in an adult Kuwaiti subpopulation using cone-beam computed tomography (CBCT) images.

Materials and Methods

Two experienced examiners analyzed 250 CBCT images obtained from Kuwaiti patients aged 15–65 years who attended government dental specialist clinics between January 2019 and September 2020. The assessment followed the radiographic scoring criteria proposed by De Moor for periapical status and the technical quality of root canal filling. Chi-square and Fisher’s exact tests were used for statistical analysis, with significance level set at p < 0.05.

Results

Among the 2,762 examined teeth, 191 (6.91%) exhibited radiographic signs of AP, and 176 (6.37%) had undergone root canal filling. AP prevalence in root canal-treated teeth was 32.38%, with a significant difference between males and females. Most of the endodontically treated teeth exhibited adequate root canal filling (71.5%).

Conclusions

The study demonstrated a comparable prevalence of AP and satisfactory execution of root canal treatment compared to similar studies in different countries.

Review Article
Does minimally invasive canal preparation provide higher fracture resistance of endodontically treated teeth? A systematic review of in vitro studies
Sıla Nur Usta, Emmanuel João Nogueira Leal Silva, Seda Falakaloğlu, Mustafa Gündoğar
Restor Dent Endod 2023;48(4):e34.   Published online October 17, 2023
DOI: https://doi.org/10.5395/rde.2023.48.e34
AbstractAbstract PDFPubReaderePub

This systematic review aimed to investigate whether minimally invasive root canal preparation ensures higher fracture resistance compared to conventional root canal preparation in endodontically treated teeth (ETT). A comprehensive search strategy was conducted on the “PubMed, Web of Science, and Scopus” databases, alongside reference and hand searches, with language restrictions applied. Two independent reviews selected pertinent laboratory studies that explored the effect of minimally invasive root canal preparation on fracture resistance, in comparison to larger preparation counterparts. The quality of the studies was assessed, and the risk of bias was categorized as low, moderate, or high. The electronic search yielded a total of 1,767 articles. After applying eligibility criteria, 8 studies were included. Given the low methodological quality of these studies and the large variability of fracture resistance values, the impact of reduced apical size and/or taper on the fracture resistance of the ETT can be considered uncertain. This systematic review could not reveal sufficient evidence regarding the effect of minimally invasive preparation on increasing fracture resistance of ETT, primarily due to the inherent limitations of the studies and the moderate risk of bias.

AbstractAbstract PDFPubReaderePub
Objectives
Pulpotomy is a minimally invasive procedure that aims to retain the vitality of the radicular pulp by removing the inflamed coronal pulp tissue. This case series presents the successful management of symptomatic irreversible pulpitis by pulpotomy with concentrated growth factor (CGF) scaffolds.
Methods
Six permanent mandibular molars with a diagnosis of symptomatic irreversible pulpitis were included. Under Local anesthesia and rubber dam isolation, caries were excavated using high-speed bur under coolant. Full coronal pulpotomy was done and hemostasis was achieved. CGF membrane was prepared and placed over the radicular pulp and layered with Biodentine (Septodont). Final restoration of type IX glass ionomer cement and bulk fill composite resin was placed. Patients were assessed for various clinical and radiographic parameters at intervals of 1 week and 3, 6, and 12 months. Five patients fulfilled the success criteria at the end of 1 year.
Results
Pulpotomy is considered an alternative treatment modality for root canal treatment in symptomatic irreversible pulpitis aiming at alleviating symptoms and maintaining vitality. CGF scaffold when used as a capping material acts as a reservoir for growth factors with anti-inflammatory properties and enhances healing.
Conclusions
Scaffold-based pulpotomy can be considered a biological approach to healing inflamed pulp.

Restor Dent Endod 2023;48(3):e26.   Published online July 26, 2023
DOI: https://doi.org/10.5395/rde.2023.48.e26
AbstractAbstract PDFPubReaderePub
Objective

This in vitro study aimed to evaluate the effects of different whitening toothpastes on a composite resin during at-home bleaching with 10% carbamide peroxide.

Materials and Methods

Sixty samples (7 mm × 2 mm) were used for color and roughness analyses, while another 60 samples (3 mm × 2 mm) were utilized to assess microhardness. The factors analyzed included toothpaste, for which 5 options with varying active agents were tested (distilled water; conventional toothpaste; whitening toothpaste with abrasive agents; whitening toothpaste with abrasive and chemical agents; and whitening toothpaste with abrasive, chemical, and bleaching agents). Brushing and application of whitening gel were performed for 14 days. Surface microhardness (SMH), surface roughness (Ra), and color (∆L*, ∆a*, ∆b, ∆E*ab, and ∆E00) were analyzed. The Ra and SMH data were analyzed using mixed generalized linear models for repeated measures, while the color results were assessed using the Kruskal-Wallis and Dunn tests.

Results

Between the initial and final time points, all groups demonstrated significant increases in Ra and reductions in SMH. No significant differences were found between groups for SMH at the final time point, at which all groups differed from the distilled water group. Conventional toothpaste exhibited the lowest Ra, while whitening toothpaste with abrasive agent had the highest value. No significant differences were observed in ∆L*, ∆a*, and ∆b.

Conclusions

While toothpaste composition did not affect the color stability and microhardness of resin composite, combining toothbrushing with whitening toothpaste and at-home bleaching enhanced the change in Ra.

Ingestion and surgical retrieval of an endodontic file: a case report

Restor Dent Endod 2023;48(4):e32.   Published online September 2, 2023

AbstractAbstract PDFPubReaderePub

Ingestions and aspirations of foreign bodies are rare, but do occasionally occur during dental treatment. Although reports exist, few include photos demonstrating the extensive surgical intervention that may be necessary to manage such events. Perhaps this lack of visualization, and associated lack of awareness, is one of the reasons some clinicians still provide non-surgical root canal therapy (NSRCT) without a rubber dam. This case report outlines the medical treatment of a 30-year-old male who initially presented to a general dentist’s office (not associated with the authors) for NSRCT of their mandibular right first molar. A rubber dam was not used for this procedure, during which the accidental ingestion of an endodontic K-file occurred. The patient was subsequently hospitalized for evaluation and treatment, consisting of numerous imaging studies, endoscopic evaluation, and surgical removal of the file from his small intestine. The ingestion of foreign bodies, and the associated complications, can be reduced through the routine use of a rubber dam, which is considered the standard of care for NSRCT. This case graphically illustrates the potential consequences associated with deviating from the standard of care and should remind clinicians that a rubber dam is necessary for all cases of NSRCT.

Evaluation of the effects of different file systems and apical functions of integrated endodontic motors on debris extrusion: an ex vivo experimental study
Sıla Nur Usta, Antonio Magan-Fernandez, Cumhur Aydın
Restor Dent Endod 2025;50(2):e14.   Published online April 14, 2025
DOI: https://doi.org/10.5395/rde.2025.50.e14
AbstractAbstract PDFPubReaderePub
Objectives
This study aimed to evaluate the effects of two different file systems operated with three apical functions of an endodontic motor integrated with an electronic apex locator on debris extrusion.
Methods
Sixty single-rooted teeth were prepared and divided into two main groups and three subgroups based on the file system (OneShape [Micro-Mega SA] and WaveOne [Dentsply Maillefer]) and apical function of the endodontic motor used (auto apical stop [AAS], auto apical reverse [AAR], and auto apical slowdown [ASD]). The teeth were mounted in pre-weighed glass tubes filled with 0.9% sodium chloride to complete the circuit with the apex locator. Files were advanced until the respective apical function (stop, reverse, or slowdown) was activated. The extruded debris was collected, dried, and weighed by subtracting pre-weighed values from post-weighed values. Preparation time was also recorded. Statistical analyses were performed to compare the groups.
Results
OneShape was associated with significantly less debris extrusion compared to WaveOne, regardless of the apical function (p < 0.05). The ASD function resulted in the least debris extrusion compared to AAS and AAR (p < 0.05). Preparation time was significantly longer in the ASD function (p < 0.05), while no differences were observed between the file systems (p > 0.05).
Conclusions
The OneShape file system and the ASD function produced the least amount of apical debris. While the ASD function requires more preparation time, its potential to minimize debris extrusion suggests it may reduce postoperative symptoms.

AbstractAbstract PDFPubReaderePub
Pulp chamber and root canal obliteration (PCO/RCO) presents a challenge for clinicians when nonsurgical endodontic treatment is indicated. Guided endodontics (GE) aims to precisely locate the root canal (RC) system while preserving as much pericervical dentin as possible. GE involves integrating cone-beam computed tomography (CBCT) of the affected tooth with a digital impression of the maxillary/mandibular arch, allowing for careful planning of the drilling path to the RC system through a three-dimensional (3D) static guide. This article reports four cases of teeth with PCO/RCO, accompanied by additional diagnoses of internal and external root resorption and horizontal tooth fracture, all successfully treated with GE. These cases highlight the clinical and radiographic success of GE treatments using CBCT, establishing this technique as a predictable approach for managing mineralized teeth.

Evaluation of at-home bleaching protocol with application on different surfaces: bleaching efficacy and hydrogen peroxide permeability
Heloisa Forville, Michael Willian Favoreto, Michel Wendlinger, Roberta Micheten Dias, Christiane Philippini Ferreira Borges, Alessandra Reis, Alessandro D. Loguercio
Restor Dent Endod 2023;48(4):e33.   Published online October 6, 2023
DOI: https://doi.org/10.5395/rde.2023.48.e33
AbstractAbstract PDFPubReaderePub
Objectives

This study aimed to evaluate the bleaching efficacy and hydrogen peroxide permeability in the pulp chamber by the at-home bleaching gel in protocols applied on different dental surfaces.

Materials and Methods

Forty premolars were randomly into 4 groups: control group no bleaching, only application on the buccal surface (OB), only application on the lingual surface (OL) and application in buccal and lingual surfaces, simultaneously (BL). At-home bleaching gel (White Class 7.5%) was used for the procedure. The bleaching efficacy was evaluated with a digital spectrophotometer (color change in CIELAB [ΔE ab] and CIEDE 2000 [ΔE 00] systems and Whitening Index for Dentistry [ΔWID]). The hydrogen peroxide permeability in the pulp chamber (µg/mL) was assessed using UV-Vis spectrophotometry and data were analyzed for a 1-way analysis of variance and Tukey’s test (α = 0.05).

Results

All groups submitted to bleaching procedure showed bleaching efficacy when measured with ΔE ab and ΔE 00 (p > 0.05). Therefore, when analyzed by ΔWID, a higher bleaching efficacy were observed for the application on the groups OB and BL (p = 0.00003). Similar hydrogen peroxide permeability was found in the pulp chambers of the teeth undergoing different protocols (p > 0.05).

Conclusions

The application of bleaching gel exclusively on the OB is sufficient to achieve bleaching efficacy, when compared to BL. Although the OL protocol demonstrated lower bleaching efficacy based on the ΔWID values, it may still be of interest and relevant in certain clinical scenarios based on individual needs, requiring clinical trials to better understand its specificities.

Micro-CT evaluation of the removal of root fillings using rotary and reciprocating systems supplemented by XP-Endo Finisher, the Self-Adjusting File, or Er,Cr:YSGG laser
Gülsen Kiraz, Bulem Üreyen Kaya, Mert Ocak, Muhammet Bora Uzuner, Hakan Hamdi Çelik
Restor Dent Endod 2023;48(4):e36.   Published online October 23, 2023
DOI: https://doi.org/10.5395/rde.2023.48.e36
AbstractAbstract PDFPubReaderePub
Objectives

This study aimed to compare the effectiveness of a single-file reciprocating system (WaveOne Gold, WOG) and a multi-file rotary system (ProTaper Universal Retreatment, PTUR) in removing canal filling from severely curved canals and to evaluate the possible adjunctive effects of XP-Endo Finisher (XPF), the Self-Adjusting File (SAF), and an erbium, chromium: yttrium, scandium, gallium garnet (Er,Cr:YSGG) laser using micro-computed tomography (μCT).

Materials and Methods

Sixty-six curved mandibular molars were divided into 2 groups based on the retreatment technique and then into 3 based on the supplementary method. The residual filling volumes and root canals were evaluated with μCT before and after retreatment, and after the supplementary steps. The data were statistically analyzed with the t-test, Mann-Whitney U test, analysis of covariance, and factorial analysis of variance (p < 0.05).

Results

PTUR and WOG showed no significant difference in removing filling materials (p > 0.05). The supplementary techniques were significantly more effective than reciprocating or rotary systems only (p < 0.01). The supplementary steps showed no significant differences in canal filling removal effectiveness (p > 0.05), but XPF showed less dentin reduction than the SAF and Er,Cr:YSGG laser (p < 0.01).

Conclusions

The supplementary methods significantly decreased the volume of residual filling materials. XPF caused minimal changes in root canal volume and might be preferred for retreatment in curved root canals. Supplementary approaches after retreatment procedures may improve root canal cleanliness.

Surgical management of maxillary sinusitis of endodontic origin after reestablishing maxillary sinus floor healing through a nonsurgical approach: a case report
Eun-Sook Kang, Min-Kyeong Kim, Mi-Kyung Yu, Kyung-San Min
Restor Dent Endod 2025;50(2):e12.   Published online April 8, 2025
DOI: https://doi.org/10.5395/rde.2025.50.e12
AbstractAbstract PDFPubReaderePub
When root canal infections breach the maxillary sinus floor (MSF), maxillary sinusitis of endodontic origin (MSEO) can result. This case illustrates the surgical management of MSEO following the nonsurgical reestablishment of the MSF. A 55-year-old woman presented with left facial pain and was diagnosed with MSEO originating from the left upper first molar. Despite undergoing nonsurgical root canal treatment, there was no evidence of bony healing after 6 months. However, cone-beam computed tomographic (CBCT) scans revealed the reestablishment of MSF. Subsequently, surgical intervention was carried out using a dental operating microscope. Two years after surgery, CBCT images indicated that the mucosal edema had resolved, and the MSF was well reestablished. Preserving the MSF is crucial for the success of endodontic surgery. When MSEO is present, the integrity of the MSF must be assessed to determine appropriate treatment options.

Davi Ariel Nobuo Bepu, Renata Siqueira Scatolin, Natalia Saud Junqueira Franco, Luiza Pejon Sanchez, Aline Evangelista Souza-Gabriel, Silmara Aparecida Milori Corona
Restor Dent Endod 2024;49(3):e24.   Published online June 11, 2024
DOI: https://doi.org/10.5395/rde.2024.49.e24
AbstractAbstract PDFPubReaderePub
Objectives

This study aimed to evaluate the clinical performance of an alkasite restorative material in molars that had undergone root canal treatment.

Materials and Methods

The research was registered in Brazilian Registry of Clinical Trials. The randomized clinical trial involved 33 patients, each with at least 1 mandibular molar requiring restoration after receiving endodontic treatment. Patients were randomly assigned to receive either bulk-fill resin composite (Tetric N Ceram Bulk Fill, Ivoclar Vivadent) or the alkasite restorative material (Cention N, Ivoclar Vivadent). Upon completion of the restorations, 3 calibrated professionals utilized the United States Public Health Service criteria to assess various factors, including retention, secondary caries, marginal adaptation, restoration color, marginal pigmentation, and anatomical form. Evaluations were conducted at intervals of 7 days, 6 months, and 17 months. Additionally, the assessment encompassed the presence of radiolucent lines adjacent to the restoration, material deficiencies or excess, contact points, and caries recurrence. The data underwent analysis using the Friedman and Mann-Whitney tests (α = 0.05).

Results

After 17 months, the results revealed that the alkasite restorative material exhibited greater wear of anatomical shape compared to the bulk-fill resin composite (p = 0.0189). Furthermore, the alkasite restorative material significantly differed from the natural tooth color in most cases (p = 0.0000). However, no other criteria displayed significant differences between the materials or over time (p > 0.05).

Conclusions

The alkasite restorative material (Cention N) emerges as a viable option for restoring endodontically treated teeth, displaying clinically acceptable alterations after a 17-month evaluation period.

AbstractAbstract PDFPubReaderePub
Objectives
This study aimed to evaluate whether the agitation protocols using ultrasonic inserts or the XP-endo Finisher R file improved the removal of two different endodontic sealer remnants and the bond strength of fiberglass posts to dentin.
Methods
Seventy-two human teeth were selected. The canals were prepared with Reciproc 50 and Easy ProDesign 30/.10 and root filled according to the endodontic sealer groups: AH Plus or EndoSequence BC Sealer HiFlow. The samples were kept at 37ºC and 95% humidity for 28 days. During the post space preparation, the obturation was removed with Largo burs, and the groups were divided according to the irrigant agitation protocols (n = 12): no agitation, agitation with R1-Clearsonic associated with E1-Irrisonic ultrasonic inserts, or agitation with XP-endo Finisher R file. The fiberglass posts were cemented with RelyX ARC. The roots were sectioned into slices and submitted to the push-out test. Micro-computed tomography analysis was used to check the effectiveness of irrigating solution agitation in the elimination of remnants.
Results
The cleaning protocols with agitation were more effective in increasing the bond strength of posts to dentin for both sealer groups compared to non-agitation (p < 0.05). There was no difference between the same cleaning protocols for the different sealers. Among the different thirds, there was no statistical difference for the same sealer in the different cleaning protocols (p > 0.05).
Conclusions
Both agitation protocols effectively clean root-filled canals sealed with resin-based and calcium silicate-based sealers during fiberglass post space preparation. These protocols result in improved bond strength compared to non-agitation methods.

Incidence of interappointment emergencies in multiple-visit root canal treatments performed with or without intracanal medicament by undergraduate students
Annemarie Baaij, Corine Mirjam Visscher, Manon Jansen, Ahmet Rifat Özok
Restor Dent Endod 2023;48(3):e31.   Published online August 14, 2023
DOI: https://doi.org/10.5395/rde.2023.48.e31
AbstractAbstract PDFPubReaderePub
Objectives

This retrospective cohort study examined the incidence of interappointment emergencies during multiple-visit molar root canal treatments conducted by undergraduate students. Treatments performed without the use of intracanal medicament were compared to treatments that incorporated calcium hydroxide as an intracanal medicament.

Materials and Methods

Interappointment emergencies, defined as instances of pain or swelling that required the patient to make an unscheduled follow-up visit, were recorded for up to 2 months after the intervention. To avoid the influence of obturation on the observed incidence of emergency visits, only unscheduled visits occurring between the start and end of the root canal treatment were included.

Results

Of the 719 patients included in this study, 77 (10.7%) were recorded as experiencing interappointment emergencies. Of these emergencies, 62% occurred within 2 weeks following the most recent intervention. In the group of patients who did not receive intracanal medicament, the incidence of interappointment emergencies was 11.9% (46 of 385 patients). In comparison, this rate was 9.3% (31 of 334 patients) among those who received calcium hydroxide as an intracanal medicament (odds ratio, 1.33; 95% confidence interval, 0.82–2.15; p = 0.249).

Conclusions

Interappointment emergencies may arise at any point during root canal treatment, but they most commonly occur within the first 2 weeks following intervention. The omission of intracanal medicament in multiple-visit molar root canal treatments, performed by undergraduate students, did not significantly increase the incidence of these emergencies.

AbstractAbstract PDFPubReaderePub
Objectives

This study aimed to present the results and analyses of clinical trials, including updates on the different functions of root canal sealers.

Materials and Methods

In June 2023, we performed a comprehensive search of ClinicalTrials.gov to identify interventional clinical trials pertaining to root canal sealers. In total, 23 clinical trials conducted up to June 2023 were included in this study.

Results

Approximately half of the trials (11 out of 23) were completed, while none were terminated or withdrawn. Each included trial had a minimum of 10 participants, with 11 trials having more than 100 participants. None of the assessed trials provided outcomes, and the majority (17 out of 23) lacked associated publications. In terms of geographic distribution, the USA and Canada did not contribute to any root canal sealer trials.

Conclusions

This study highlights the lack of diversity in trial locations, the absence of reported results, and a scarcity of clinical trials examining the physicochemical properties of different sealers. Most published trials primarily focused on assessing the post-operative pain effect of these sealers, but no significant difference was found regarding post-operative pain control.

Restor Dent Endod 2023;48(2):e12.   Published online March 8, 2023
DOI: https://doi.org/10.5395/rde.2023.48.e12
AbstractAbstract PDFPubReaderePub
Objectives

The present study evaluated the pulp response of human mandibular incisors subjected to in-office dental bleaching using gels with medium or high concentrations of hydrogen peroxide (HP).

Materials and Methods

The following groups were compared: 35% HP (HP35; n = 5) or 20% HP (HP20; n = 4). In the control group (CONT; n = 2), no dental bleaching was performed. The color change (CC) was registered at baseline and after 2 days using the Vita Classical shade guide. Tooth sensitivity (TS) was also recorded for 2 days post-bleaching. The teeth were extracted 2 days after the clinical procedure and subjected to histological analysis. The CC and overall scores for histological evaluation were evaluated by the Kruskal-Wallis and Mann-Whitney tests. The percentage of patients with TS was evaluated by the Fisher exact test (α = 0.05).

Results

The CC and TS of the HP35 group were significantly higher than those of the CONT group (p < 0.05) and the HP20 group showed an intermediate response, without significant differences from either the HP35 or CONT group (p > 0.05). In both experimental groups, the coronal pulp tissue exhibited partial necrosis associated with tertiary dentin deposition. Overall, the subjacent pulp tissue exhibited a mild inflammatory response.

Conclusions

In-office bleaching therapies using bleaching gels with 20% or 35% HP caused similar pulp damage to the mandibular incisors, characterized by partial necrosis, tertiary dentin deposition, and mild inflammation.

AbstractAbstract PDFPubReaderePub
Objectives
The aim of this study was to demonstrate the impact of a high-power 810-nm diode laser as monotherapy on the clinical and tomographic success of treating teeth with periapical lesions, through a series of 31 cases.
Methods
Teeth with apical lesions underwent endodontic treatment in which a high-power 810-nm diode laser with saline solution was used as monotherapy for disinfection. This type of therapy aimed to replace the traditional irrigation protocol with sodium hypochlorite. This research is the first to assess the clinical success of this alternative treatment, along with tomographic evaluations conducted over periods ranging from 2 to 7 years, analyzed using the periapical index based on cone-beam computed tomography (CBCTPAI). All cases were performed by a single clinician following the same laser protocol, which involved using 1 W of continuous power and four cycles of 20 seconds of laser activation.
Results
All teeth showed no clinical symptoms upon follow-up examination. However, the tomographic evaluation revealed that the success rates for teeth receiving primary treatment were 60% and 80% according to strict and loose criteria, respectively. For teeth requiring retreatment, the success rates were 12.5% and 37.5% using strict and loose criteria, respectively.
Conclusions
The teeth with apical lesions that underwent primary treatment did not present clinical symptoms, but they showed a moderate success rate on tomographic evaluation. However, despite lacking clinical symptoms, teeth with apical lesions that required retreatment had a very low success rate on tomographic evaluation.

AbstractAbstract PDFSupplementary MaterialPubReaderePub

The surface integrity of gutta-percha cones is a crucial factor in the success of endodontic procedures. Disinfecting solutions play a pivotal role in sterilizing gutta-percha cones, but their influence on gutta-percha surface topography remains a subject of concern. This systematic review aimed to present a qualitative synthesis of available laboratory studies assessing the influence of disinfecting solutions on the surface topography of gutta-percha and offers insights into the implications for clinical practice. The present review followed PRISMA 2020 guidelines. An advanced database search was performed in PubMed, Google Scholar, Embase, Scopus, LILAC, non-indexed citations and reference lists of eligible studies in May 2024. Laboratory studies, in English language, were considered for inclusion. The quality (risk of bias) of the included studies was assessed using parameters for in vitro studies. A total of 28 studies were included in the qualitative synthesis. Based on the included in vitro studies, surface deposits and alterations in the physical properties of gutta-percha cones were observed after the disinfection protocol. A comprehensive review of the available literature indicates that the choice of disinfecting solution, its concentration, and immersion time significantly affect the surface topography of gutta-percha cones.

AbstractAbstract PDFPubReaderePub

From the restorative perspective, various methods are available to prevent the progression of non-carious cervical lesions. Direct, semi-direct, and indirect composite resin techniques and indirect ceramic restorations are commonly recommended. In this context, semi-direct and indirect restoration approaches are increasingly favored, particularly as digital dentistry becomes more prevalent. To illustrate this, we present a case report demonstrating the efficacy of hybrid ceramic fragments fabricated using computer-aided design (CAD)/computer-aided manufacturing (CAM) technology and cemented with resin cement in treating non-carious cervical lesions over a 48-month follow-up period. A 24-year-old male patient sought treatment for aesthetic concerns and dentin hypersensitivity in the cervical region of the lower premolar teeth. Clinical examination confirmed the presence of two non-carious cervical lesions in the buccal region of teeth #44 and #45. The treatment plan involved indirect restoration using CAD/CAM-fabricated hybrid ceramic fragments as a restorative material. After 48 months, the hybrid ceramic material exhibited excellent adaptation and durability provided by the CAD/CAM system. This case underscores the effectiveness of hybrid ceramic fragments in restoring non-carious cervical lesions, highlighting their long-term stability and clinical success.

Objectives

This study tested the hypothesis that cryotherapy duration influences lipopolysaccharide (LPS)-induced inflammation in a rat model.

Materials and Methods

Six Wistar rats (Rattus norvegicus albinus) were used. Five sites were selected per animal and divided into 5 groups: a negative control group (NC), 2 positive control groups (PC1 and PC2), and 2 experimental groups (E1 and E2). Cryotherapy was applied for 1 minute (E1) or 5 minutes (E2). An acute inflammatory response was induced in the PC and E groups via subcutaneous administration of 0.5 mL/kg. In the PC2 group, a catheter was inserted without additional treatment. For the E1 and E2 groups, 2.5°C saline solution was administered through the implanted catheters for 1 and 5 minutes, respectively. The rats were sacrificed, and samples were obtained and processed for histological analysis, specifically examining the presence of polymorphonuclear neutrophils and hemorrhage. The χ2 test was used to compare the presence of acute inflammation across groups. Dependent variables were compared using the linear-by-linear association test.

Results

Inflammation and hemorrhage varied significantly among the groups (p = 0.001). A significantly higher degree of acute inflammation was detected (p = 0.0002) in the PC and E1 samples than in the E2 group, in which cryotherapy was administered for 5 minutes. The PC and E1 groups also exhibited significantly greater numbers of neutrophils (p = 0.007), which were essentially absent in both the NC and E2 groups.

Conclusions

Cryotherapy administration for 5 minutes reduced the acute inflammation associated with LPS and catheter implantation.

Pulp stones: any relevance with the levels of serum calcium, parathyroid hormone, vitamin D and uric acid
Ceyda Gürhan, Ercan Saruhan
Restor Dent Endod 2024;49(2):e17.   Published online March 26, 2024
DOI: https://doi.org/10.5395/rde.2024.49.e17
AbstractAbstract PDFPubReaderePub
Objectives

This study evaluated the effect of serum calcium, parathyroid hormone (PTH), vitamin D, and uric acid levels on pulp stone formation.

Materials and Methods

Patients who were admitted to the Muğla Sıtkı Koçman University, Faculty of Dentistry, Department of Oral and Maxillofacial Radiology for dental complaints were registered. Among these patients, individuals who had routine biochemical tests at the same period in the Outpatient Clinics of Muğla Sıtkı Koçman University Training and Research Hospital were included in the study. The patients with at least 1 pulp stone on panoramic radiographs recorded as the “pulp stone group” while patients without any pulp stones were the “control group”. Demographic data and serum levels of calcium, PTH, vitamin D, and uric acid were retrospectively evaluated in both groups. Student t-test or Mann-Whitney U test was used to evaluate the differences between the groups.

Results

Among 151 patients, dental pulp stone was detected in 53.6% of patients, and 82.7% of these patients were female. Female sex and pulp stone formation were significantly associated (p = 0.001). The mean age of the pulp stone group was 43.9, while it was 39.9 in the control group, without any significant correlation between age and pulp stone (p > 0.05). Similarly, there were no significant differences in serum levels of PTH, vitamin D, uric acid and calcium between groups (p > 0.05).

Conclusions

According to the present study, the effect of dental factors rather than systemic factors should be considered primarily in pulp stone formation.

Push-out bond strength and intratubular biomineralization of a hydraulic root-end filling material premixed with dimethyl sulfoxide as a vehicle
Ju-Ha Park, Hee-Jin Kim, Kwang-Won Lee, Mi-Kyung Yu, Kyung-San Min
Restor Dent Endod 2023;48(1):e8.   Published online January 20, 2023
DOI: https://doi.org/10.5395/rde.2023.48.e8
AbstractAbstract PDFPubReaderePub
Objectives

This study was designed to evaluate the parameters of bonding performance to root dentin, including push-out bond strength and dentinal tubular biomineralization, of a hydraulic bioceramic root-end filling material premixed with dimethyl sulfoxide (Endocem MTA Premixed) in comparison to a conventional powder-liquid–type cement (ProRoot MTA).

Materials and Methods

The root canal of a single-rooted premolar was filled with either ProRoot MTA or Endocem MTA Premixed (n = 15). A slice of dentin was obtained from each root. Using the sliced specimen, the push-out bond strength was measured, and the failure pattern was observed under a stereomicroscope. The apical segment was divided into halves; the split surface was observed under a scanning electron microscope, and intratubular biomineralization was examined by observing the precipitates formed in the dentinal tubule. Then, the chemical characteristics of the precipitates were evaluated with energy-dispersive X-ray spectroscopic (EDS) analysis. The data were analyzed using the Student’s t-test followed by the Mann-Whitney U test (p < 0.05).

Results

No significant difference was found between the 2 tested groups in push-out bond strength, and cohesive failure was the predominant failure type. In both groups, flake-shaped precipitates were observed along dentinal tubules. The EDS analysis indicated that the mass percentage of calcium and phosphorus in the precipitate was similar to that found in hydroxyapatite.

Conclusions

Regarding bonding to root dentin, Endocem MTA Premixed may have potential for use as an acceptable root-end filling material.

AbstractAbstract PDFPubReaderePub
Objectives

This study aimed to investigate the effect of the application method of 2% chlorhexidine (CHX) and its influence on the adhesion of fiberglass posts cemented with a self-adhesive resin cement.

Materials and Methods

Sixty human mandibular premolars were endodontically treated and divided into 5 groups (n = 12), according to the canal irrigant and its application method: 2 groups with conventional syringe irrigation (CSI)—2.5% sodium hypochlorite (NaOCl) (control) and 2% CHX— and 3 groups with 2% CHX irrigation/activation—by passive ultrasonic irrigation (PUI), Easy Clean file, and XP-Endo Finisher file. Two roots per group were evaluated for smear layer (SL) removal by scanning electron microscopy. For other roots, fiber posts were luted using a self-adhesive resin cement. The roots were sectioned into 6 slices for push-out bond strength (BS) (7/group) and nanoleakage (NL) (3/group). Data from SL removal were submitted to Kruskal-Wallis and Student-Newman-Keuls tests (α = 0.05). Data from BS and NL were evaluated by 2-way analysis of variance and Tukey’s test (α = 0.05).

Results

For SL removal and BS, the CHX irrigation/activation promoted better values than CSI with CHX (p < 0.05), but it was not significantly different from CSI with NaOCl (p > 0.05). For NL, the lowest values were obtained by the chlorhexidine irrigation/activation groups (p < 0.05).

Conclusions

Active 2% CHX irrigation can be used to improve the post space cleaning and adhesion before fiber post cementation with self-adhesive resin cements.

Can discolored dental composites be bleached in depth?
Luca Giachetti, Daniele Scaminaci Russo, Michele Nieri, Francesca Cinelli
Restor Dent Endod 2024;49(3):e23.   Published online June 11, 2024
DOI: https://doi.org/10.5395/rde.2024.49.e23
AbstractAbstract PDFPubReaderePub
Objectives

Previous in vitro studies determined the whitening effects of bleaching products on stained resin composite surfaces. This in vitro study aimed to verify the effectiveness of a whitening system on composite resin previously subjected to pigmentation, specifically examining the depth of whitening effectiveness within the material structure.

Materials and Methods

A commercially available nano-filled composite resin was used. Specimens were stained using a coffee-based solution and a 10% carbamide peroxide-based gel was employed as the whitening agent. The pigment’s penetration and the effect of the bleaching gel were evaluated by measuring color (CieLab values) from the outer edge to the inner part of the specimens. Color measurements were taken at 14 points, starting from 0.1 mm from the external perimeter up to 3.0 mm.

Results

Analysis of variance tests showed a statistically significant difference between the Control Group (CG), Pigmentation Group, and Whitening Group. The whitening agent was effective up to 1.5 mm in depth, with Whiteness index (W) values not statistically different from those of CG up to 0.5 mm in depth.

Conclusions

Whitening agents on nano-filled resin composite previously pigmented appear effective in restoring the W to values similar to the original, particularly in the superficial layers of the sample.

Objectives
The study aimed to conduct a bibliometric analysis of the GentleWave system (Sonendo, Inc.).
Methods
An electronic search was conducted in June 2024 using the Web of Science Collection database. Two reviewers independently screened publications, extracting data on authorship, publication details, study design, and citation metrics. Statistical analyses were performed in R to assess variable correlations, while the VOSviewer (Visualization of Similarities Viewer) software was used to map author and keyword networks.
Results
The search yielded 47 records, with 32 studies included. Publications spanned 2014 to 2024. The Journal of Endodontics published the highest number of studies (n = 15), and the International Endodontic Journal had the highest impact factor (5.4). The University of British Columbia and Sonendo, Inc. were the most frequent affiliations. Among the 32 articles, 28 were in vitro studies, primarily focusing on microbiology (n = 9). A total of 95 authors were identified, with Haapasalo and Shen being the most cited (n = 229). The articles accumulated 495 citations, demonstrating a strong positive correlation between the number of studies and citation counts (r = 0.98).
Conclusions
The analysis highlights a predominance of in vitro studies. Geographic concentration in the United States and Canada limits diversity, while the strong correlation between study numbers and citations suggests that increased publication volume enhances visibility.

Endodontic characteristics of mandibular premolar with dens evaginatus: a retrospective study
Minjin Kim, Sujin Jeon, Min-Seock Seo
Restor Dent Endod 2024;49(3):e28.   Published online July 11, 2024
DOI: https://doi.org/10.5395/rde.2024.49.e28
AbstractAbstract PDFPubReaderePub
Objectives

This study aimed to investigate the endodontic characteristics of mandibular premolars with dens evaginatus (DE) that require endodontic treatment.

Materials and Methods

Patients who underwent endodontic treatment were enrolled. The inclusion criteria were patients who underwent root canal treatment in the lower permanent teeth with DE and were followed up for at least 1 year. Preoperative clinical and radiographic variables were obtained. The frequency distribution of the preoperative variables was compared using the χ2 or Fisher’s exact tests. The significance of the change in periapical health index (PAI) and root development stages before and after treatment was examined using the Wilcoxon signed-rank test.

Results

A total of 150 teeth of 134 patients with an average age of 15.3 years were included. The percentage distribution comparison of the preoperative variables and obturation techniques revealed significant differences in pulpal and periapical diagnosis, and percussion, and especially regarding age, root development stage, and PAI. Age was the only statistically significant preoperative variable associated with root growth (p < 0.05).

Conclusions

Approximately, 60% of DEs requiring endodontic treatment had immature roots. Age being the most significant predisposing factor, early treatment provides the greatest opportunity for full root development.

Predictive factors in the retrieval of endodontic instruments: the relationship between the fragment length and location
Ricardo Portigliatti, Eugenia Pilar Consoli Lizzi, Pablo Alejandro Rodríguez
Restor Dent Endod 2024;49(4):e35.   Published online September 9, 2024
DOI: https://doi.org/10.5395/rde.2024.49.e35
AbstractAbstract PDFPubReaderePub
Objectives

This study aimed to relate the file fragment length and location in the root canal to the retrieval chances, the clinical time required and the occurrence of secondary fractures.

Materials and Methods

Sixty clinical cases of fractured instruments were included in this study. They were classified according to the instrument length and the location of the root canal. In each group, the success rate in the instrument retrieval, the clinical time required and the occurrence of secondary fractures were evaluated. The collected data were analyzed using the Kruskal-Wallis test on the basis of a 0.05 significance level.

Results

The fragment length showed no significant influence on the assessed variables (p > 0.05). The root third where the instrument was located resulted in an increased clinical time, with statistically significant differences (p < 0.05). However, the procedure success rate and the occurrence of secondary fractures showed no association with these variables.

Conclusions

In accordance with the findings of this study, the fractured fragment length did not influence any of the variables assessed, but it is suggested to focus on the fragment location inside the root canal to decide the retrieval of a fractured instrument.
