A comparison of MTA and Biodentine as medicaments for pulpotomy in traumatized anterior immature permanent teeth: A randomized clinical trial.

Background/aim: The placement of a biocompatible material after performing pulp therapy in traumatically exposed permanent incisors is one of the important factors that determine pulp healing. The aim of this study was to assess the clinical and radiographic outcomes when using mineral trioxide aggregate (MTA) and Biodentine as pulpotomy materials to maintain the vitality of traumatized immature anterior permanent teeth with pulp exposure.

Materials And Methods: Fifty traumatized immature anterior permanent teeth with exposed pulps were included in the study. Teeth were equally divided and randomly assigned to two groups MTA or Biodentine. After pulpotomy, pulp stumps were covered with MTA or Biodentine followed by a permanent restoration. Blinded clinical and radiographic evaluations were performed at baseline, immediate post-operative and after 6, 12 and 18 months according to pre-determined clinical and radiographic criteria.

Results: No statistically significant differences were observed between MTA and Biodentine for any of the clinical parameters, except for discoloration, which was significantly more prevalent in the MTA group (P < .001). No significant statistical difference was observed in the radiographic outcomes between MTA and Biodentine, as evidenced by continued root development and by an increased prevalence of root formation stage H in both groups.

Conclusions: Both MTA and Biodentine showed similar clinical and radiographic outcomes when used as pulpotomy materials in the treatment of traumatized immature anterior permanent teeth. However, discoloration was significantly more prevalent in the MTA group.
