Root canal treatment (RCT) is preferred treatment for mature teeth with irreversible pulpitis. But sometimes it is very difficult to perform due to complex pulpal anatomy and the vitality of tooth is completely lost by this procedure. A new hope has been emerged to consider pulpotomy treatment as an effective treatment in mature permanent teeth with irreversible pulpitis as with the new understanding of pulp biology and recent innovation of bioactive material like MTA. The aim of the study was to evaluate the outcome of MTA pulpotomy for mature third molars with symptoms indicative of irreversible pulpitis. This quasi-experimental study was conducted at Department of Conservative Dentistry and Endodontics, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from September 2019 to August 2020. Twenty permanent mandibular third molar teeth with fully developed roots and diagnosed as irreversible pulpitis in 20 patients aged 25-50 years were selected for this study. After informed consent, each tooth was anaesthetized, isolated with dental dam and disinfected with 5% NaOCl before caries excavation; caries was removed, and then, a full pulpotomy was performed. Haemostasis was achieved and MTA (Angelus, Brazil) was placed as the pulpotomy agent over the pulp chamber floor covering the canal orifices and rest of the cavity was sealed with glass-ionomer filling over the set MTA. Clinical and radiographic evaluation was completed at 3 months, 6 months, and 1 year postoperatively. Descriptive statistics were used to assess outcomes. The recall rate ranged from 90% at 3 months to 85% at 1 year, with an overall 100% clinical and radiographic success during the 3 month and 6 month, and 95% success at the end of 1 year. MTA pulpotomy sustained a good success rate over the 1 year follow-up in mature third molar teeth clinically diagnosed with irreversible pulpitis.

Comparative evaluation of the effect of two pulpal medicaments on pain and bleeding status of mandibular molars with irreversible pulpitis post-failure of inferior alveolar nerve block: a double-blind, randomized, clinical trial.

Department of Conservative Dentistry, Faculty of Dental Medicine, Universitas Airlingga, Surabaya City, East Java, Indonesia.

Background: Complete relief of pain due to irreversible pulpitis is challenging to obtain with analgesic medications. The high incidence of an inferior alveolar nerve block (IANB) failure makes it difficult for practitioners to perform endodontic treatment without implementing other anesthetic techniques, especially mandibular molars. The aim of this study was to compare efficacies of two different quantities of paraformaldehyde based pulpal medicaments to relieve the pain and control hyperemic pulp post-failure of IANB and supplementary technique in patients experiencing this symptomatic irreversible pulpitis in the permanent mandibular tooth.

Department of Nursing, West China Hospital of Stomatology, Sichuan University, Chengdu, China.

Background: This study aimed to evaluate the effect of mineral trioxide aggregate (MTA) pulp capping for caries-exposed permanent teeth. However, the efficacy of MTA in the treatment of children's gums is still controversial, and different studies have shown different efficacy. Therefore, it is necessary to systematically review the efficacy and safety of MTA pulp incision in the treatment of pediatric caries using meta methods. Read More
