Abstract PDF PubReader ePub: 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.

Efficacy of buccal piroxicam infiltration and inferior alveolar nerve block in patients with irreversible pulpitis: a prospective, double-blind, randomized clinical trial: Saurav Paul, Sridevi Nandamuri, Aakrati Raina, Mukta Bansal; Restor Dent Endod 2021;46(1):e9.

Objectives

This randomized clinical trial aimed to assess the effectiveness of buccal infiltration with piroxicam on the anesthetic efficacy of inferior alveolar nerve block (IANB) with buccal infiltration in irreversible pulpitis, with pain assessed using the Heft-Parker visual analogue scale (HP-VAS).

Materials and Methods

This study included 56 patients with irreversible pulpitis in mandibular molars, randomly distributed between 2 groups (n = 28). After evaluating the initial pain score with the HP-VAS, each patient received IANB followed by buccal infiltration of 2% lignocaine with adrenaline (1:80,000). Five minutes later, the patients in groups 1 and 2 were given buccal infiltration with 40 mg/2 mL of piroxicam or normal saline, respectively. An access opening procedure (AOP) was performed 15 minutes post-IANB once the individual showed signs of lip numbness as well as 2 negative responses to electric pulp testing. The HP-VAS was used to grade the patient's pain during caries removal (CR), AOP, and working length measurement (WLM). Successful anesthesia was identified either by the absence of pain or slight pain through CR, AOP, and WLM, with no requirement of a further anesthetic dose. A statistical analysis was done using the Shapiro-Wilk and Mann-Whitney U tests.

Results

The piroxicam group presented a significantly lower (p < 0.05) mean pain score than the saline group during AOP.

Conclusions

Buccal infiltration with piroxicam enhanced the efficacy of anesthesia with IANB and buccal infiltration with lignocaine in patients with irreversible pulpitis.

The success rate of bupivacaine and lidocaine as anesthetic agents in inferior alveolar nerve block in teeth with irreversible pulpitis without spontaneous pain: Masoud Parirokh, Mohammad Hosein Yosefi, Nouzar Nakhaee, Paul V. Abbott, Hamed Manochehrifar; Restor Dent Endod 2015;40(2):155-160. Published online March 16, 2015; DOI: https://doi.org/10.5395/rde.2015.40.2.155

Objectives

Achieving adequate anesthesia with inferior alveolar nerve blocks (IANB) is of great importance during dental procedures. The aim of the present study was to assess the success rate of two anesthetic agents (bupivacaine and lidocaine) for IANB when treating teeth with irreversible pulpitis.

Materials and Methods

Sixty volunteer male and female patients who required root canal treatment of a mandibular molar due to caries participated in the present study. The inclusion criteria included prolonged pain to thermal stimulus but no spontaneous pain. The patients were randomly allocated to receive either 2% lidocaine with 1:80,000 epinephrine or 0.5% bupivacaine with 1:200,000 epinephrine as an IANB injection. The sensitivity of the teeth to a cold test as well as the amount of pain during access cavity preparation and root canal instrumentation were recorded. Results were statistically analyzed with the Chi-Square and Fischer's exact tests.

Results

At the final step, fifty-nine patients were included in the study. The success rate for bupivacaine and lidocaine groups were 20.0% and 24.1%, respectively. There was no significant difference between the two groups at any stage of the treatment procedure.

Conclusions

There was no difference in success rates of anesthesia when bupivacaine and lidocaine were used for IANB injections to treat mandibular molar teeth with irreversible pulpitis. Neither agent was able to completely anesthetize the teeth effectively. Therefore, practitioners should be prepared to administer supplemental anesthesia to overcome pain during root canal treatment.
