Evaluation of Mineral Trioxide Aggregate and Biodentine as pulpotomy agents in immature first permanent molars with carious pulp exposure: A randomised clinical trial

Abstract

Aim There is insufficient evidence on the outcome of pulpotomies in carious exposed young permanent molars with newer biomaterials. This study aimed to compare Mineral Trioxide Aggregate (MTA) and Biodentine as pulpotomy materials in carious exposed vital immature mandibular first permanent molars. Materials and methods Study design: Sixty immature first mandibular permanent molars, with carious exposure were randomly assigned to an MTA or Biodentine group in a split-mouth design. After the amputation of the coronal pulp, the pulp stumps were covered with one of the study materials and coronal restorations placed. Blinded clinical and radiographic evaluations were performed at baseline. Following this there were evaluations at 6, 12 and 18 months where comparisons between and within the two groups were made. Results A high success was observed in both groups for all outcome measures for clinical success, with no significant difference between them. The mean survival time for the Biodentine and MTA groups was (17.8 and 18 months) with 95% confidence interval (17.4-18.2) and (18 .0-18.0) months respectively. Similarly, there were no significant differences between the Biodentine and MTA groups for radiographic success (P<0.001) with an increase in root length and increasing apical closure observed in both groups. Conclusions Both materials were equally effective in the treatment of cariously exposed vital immature mandibular first permanent molars 2021. All Rights Reserved.
