Aim: To assess the clinical and radiographic outcomes of mineral trioxide aggregate (MTA) and Biodentine as vital pulpotomy materials to maintain the vitality of traumatized immature anterior permanent teeth with pulpal exposure. Materials and Methods: Fifty vital traumatized immature anterior permanent teeth with exposed pulps were included in the study. Teeth were equally divided and randomly assigned to either a control group (MTA) or the test group (Biodentine). After pulpotomy, pulp stumps were covered with MTA or Biodentine followed by a permanent restoration. Blinded clinical and radiographic evaluations were performed at base line, 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<0.001). No significant statistical difference was observed in the radiographic success between MTA and Biodentine, as evidenced by continued root development presented 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 vital pulpotomy materials in the treatment of traumatized immature anterior permanent teeth. However, discoloration was significantly more prevalent in the MTA group, and given similar clinical and radiographic outcomes in the two groups, Biodentine should be favored over MTA after pulpotomy for anterior traumatized teeth with pulpal exposure where aesthetics would be of concern.
