Evaluation of The Success of Mature Molar Pulpotomies Using MTA Versus Biodentine. A Clinical Study

Abstract

Objectives: This study was aimed to evaluate the success of adult pulpotomies for permanent molars with irreversible pulpitis using MTA versus Biodentine. Subjects and Methods : Forty-four patients with carious permanent molars with signs and symptoms of irreversible pulpitis were included in the study. Cases were randomly grouped into 2 groups: MTA and Biodentine. After caries removal and access cavity preparation, excavation of all coronal pulp to the floor of the pulp chamber was achieved. Control of bleeding was done using pressure with a saline-soaked cotton pellet. The capping material was prepared according to the manufacturer’s instructions. In the MTA group, after MTA application to the floor of the pulp chamber, a wet cotton pellet was placed over the MTA, then the tooth was temporized. Forty-eight hours later, the cotton pellet was removed, and the final filling was applied. In the Biodentine group, the final filling was placed 12 min. after Biodentine application. The patients were followed after 12, and 18 months. Results : After 12-months follow-up, the success rate was 86.4% for the MTA versus 81.8% for the Biodentine. After 18-months, the success rate was 85.7% for the MTA versus 75% for the Biodentine. There was no statistically significant difference between the success rate of MTA and Biodentine. Conclusions : Higher success rate could be attained in adult pulpotomies using bioactive materials. Irreversible pulpitis is not a contraindication for adult pulpotomies.
