Physical properties of novel composite using Portland cement for retro-filling material: Sang-Jin Lee, Ok-In Cho, Jiwan Yum, Jeong-Kil Park, Bock Hur, Hyeon-Cheol Kim; J Korean Acad Conserv Dent 2010;35(6):445-452. Published online November 30, 2010; DOI: https://doi.org/10.5395/JKACD.2010.35.6.445

Objectives

The aim of this study was to compare apical sealing ability and physical properties of MTA, MTA - AH-plus mixture (AMTA) and experimental Portland cement - Epoxy resin mixture (EPPC) for a development of a novel retro-filling material.

Materials and Methods

Forty-nine extracted roots were instrumented and filled with gutta-percha. Apical root was resected at 3 mm and the retro-filling cavity was prepared for 3 mm depth. Roots were randomly divided into 3 groups of 15 roots each. The retro-filling was done using MTA, AMTA, and EPPC as the groups divided. Four roots were used as control groups. After setting in humid condition for 24 hours, the roots were immersed in 1% methylene blue dye solution for 72 hours to test the apical leakage. After immersion, the roots were vertically sectioned and photos were taken to evaluate microleakage. Setting times were measured with Vicat apparatus and digital radiographs were taken to evaluate aluminum equivalent thickness using aluminum step wedge. The results of microleakage and setting time were compared between groups using one-way ANOVA and Scheffe's post-hoc comparison at the significance level of 95%.

Results

AMTA and EPPC showed less microleakage than MTA group (p < 0.05). AMTA showed the highest radio-opacity than other groups and the novel EPPC showed 5 mm aluminum thickness radio-opacity. EPPC showed the shortest initial and final setting times than other groups while the MTA showed the longest (p < 0.05).

Conclusions

Under the condition of this study, the novel composite using Portland cement-Epoxy resin mixture may useful for retro-filling with the properties of favorable leakage resistance, radio-opacity and short setting time.

Mineral trioxied aggregate and its substitutes: Yong-Bum Cho; J Korean Acad Conserv Dent 2010;35(3):149-151. Published online May 31, 2010; DOI: https://doi.org/10.5395/JKACD.2010.35.3.149

Abstract PDF PubReader ePub

Since its introduction in 1993, Mineral Trioxide Aggregate (MTA) has been shown to be superior to others in sealing, biocompatibility, and many other aspects of clinical endodontics. MTA is primarily Portland cement with bismuth oxide as a radiopacitifier.

Although some studies suggested that the reasonable-priced Portland cement could be used instead of MTA, but MTAs are different from Portland cement in its composition, especially in heavy metal contents. Therefore, clinicians should be meticulous adapting the Portland cement as a MTA substitute.

A bioactivity study of Portland cement mixed with β-glycerophosphosphate on human pulp cell: Young-Hwan Oh, Young-Joo Jang, Yong-Bum Cho; J Korean Acad Conserv Dent 2009;34(5):415-423. Published online September 30, 2009; DOI: https://doi.org/10.5395/JKACD.2009.34.5.415

Abstract PDF PubReader ePub

The purpose of this study is to investigate the response of human pulp cell on Portland cement mixed with β-glycerophosphate. To investigate the effect of β-glycerophosphate and/or dexamethasone on human pulp cell, ALP activity on various concentration of β-glycerophosphate and dexamethasone was measured and mineral nodule of human pulp cell was stained with Alizarin red S. MTS assay and ALP activity of human pulp cell on Portland cement mixed with various concentration of β-glycerophosphate (10 mM, 100mM, 1M) was measured and the specimens were examined under SEM.

Addition of β-glycerophosphate or dexamethasone alone had no effect however, the addition of 5 mM β-glycerophosphate and 100 nM dexamethasone had the largest increasement in ALP activity. There was no toxicity in all samples and the data showed that Portland cement mixed with 10 mM β-glycerophosphate had more increase in ALP activity compared with control.

In conclusion, Portland cement mixed with β-glycerophosphate has no toxicity and promotes differentiation and mineralization of pulp cell compared with additive-free Portland cement. This implicated that application of Portland cement mixed with β-glycerophosphate might form more reparative dentin and in turn it would bring direct pulp capping to success.

Comparison of biocompatibility of four root perforation repair materials: Min-Kyung Kang, In-Ho Bae, Jeong-Tae Koh, Yun-Chan Hwang, In-Nam Hwang, Won-Mann Oh; J Korean Acad Conserv Dent 2009;34(3):192-198. Published online May 31, 2009; DOI: https://doi.org/10.5395/JKACD.2009.34.3.192

Abstract PDF PubReader ePub

This study was carried out in order to determine in vitro biocompatibility of white mineral trioxide aggregate (MTA), and to compare it with that of the commonly used materials, i. e. calcium hydroxide liner (Dycal), glass ionomer cement (GIC), and Portland cement which has a similar composition of MTA. To assess the biocompatibility of each material, cytotoxicity was examined using MG-63 cells. The degree of cytotoxicity was evaluated by scanning electron microscopy (SEM) and a colorimetric method, based on reduction of the tetrazolium salt 2,3 bis {2methoxy 4nitro 5[(sulfenylamino) carbonyl] 2H tetrazolium hydroxide} (XTT) assay.

The results of SEM revealed the cells in contact with GIC, MTA, and Portland cement at 1 and 3 days were apparently healthy. In contrast, cells in the presence of Dycal appeared rounded and detached. In XTT assay, the cellular activities of the cells incubated with all the test materials except Dycal were similar, which corresponded with the SEM observation. The present study supports the view that MTA is a very biocompatible root perforation repair material. It also suggests that cellular response of Portland cement and GIC are very similar to that of MTA.

Ingredients and cytotoxicity of MTA and 3 kinds of Portland cements: Seok-Woo Chang, Hyun-Mi Yoo, Dong Sung Park, Tae-Seok Oh, Kwang-Shik Bae; J Korean Acad Conserv Dent 2008;33(4):369-376. Published online July 31, 2008; DOI: https://doi.org/10.5395/JKACD.2008.33.4.369

Abstract PDF PubReader ePub

The aim of this study was to compare the compositions and cytotoxicity of white ProRoot MTA (white mineral trioxide aggregate) and 3 kinds of Portland cements. The elements, simple oxides and phase compositions of white MTA (WMTA), gray Portland cement (GPC), white Portland cement (WPC) and fast setting cement (FSC) were measured by inductively coupled plasma atomic emission spectrometry (ICP-AES), X-ray fluorescence spectrometry (XRF) and X-ray diffractometry (XRD). Agar diffusion test was carried out to evaluate the cytotoxicity of WMTA and 3 kinds of Portland cements.

The results showed that WMTA and WPC contained far less magnesium (Mg), iron (Fe), manganese (Mn), and zinc (Zn) than GPC and FSC. FSC contained far more aluminum oxide (Al₂O₃) than WMTA, GPC, and WPC. WMTA, GPC, WPC and FSC were composed of main phases, such as tricalcicium silicate (3CaO·SiO₂), dicalcium silicate (2CaO·SiO₂), tricalcium aluminate (3CaO·Al₂O₃), and tetracalcium aluminoferrite (4CaO·Al₂O₃·Fe₂O₃). The significance of the differences in cellular response between WMTA, GPC, WPC and FSC was statistically analyzed by Kruskal-Wallis Exact test with Bonferroni's correction. The result showed no statistically significant difference (p > 0.05).

WMTA, GPC, WPC and FSC showed similar compositions. However there were notable differences in the content of minor elements, such as aluminum (Al), magnesium, iron, manganese, and zinc. These differences might influence the physical properties of cements.
