Evaluation of the efficacy of mineral trioxide aggregate and bioceramic putty in primary molar pulpotomy with symptoms of irreversible pulpitis (a randomized-controlled trial)

Abstract

Objectives: Preserving the primary teeth is important, as they play an important role in the integrity of the dental arch, the development of the craniofacial complex, speech, and chewing. This study aimed to evaluate the effectiveness of both Mineral Trioxide Aggregate (MTA) and Bioceramic putty in primary molar pulpotomy with symptoms of irreversible pulpitis. Materials and Methods: In this study, 40 s primary mandibular molars in 40 healthy children aged 6−8 years were examined and classified into 2 groups according to the material: group A, with 20 primary molars capped by MTA, and group B, with 20 teeth capped by Bioceramic putty. Clinical and radiographic evaluation of the treatment results was carried out after 1 week, 3 months, 6 months, 9 months, and 1 year. Results: Clinical and radiological success rates in the MTA group reached 95%, where a case of failure was observed after a year of follow-up. In the Bioceramic group, the success rate reached 100% after a year of follow-up, without any statistically significant differences between groups (p =.311). Conclusions: Pulpotomy using biocompatibility materials (MTA-Bioceramic) in primary molars with symptoms of irreversible pulpitis is considered effective due to the better advantages of the use of Bioceramic over MTA. This clinical trial was approved by Australian New Zealand Clinical Trials (12621001631897).
