A retrospective review of Biodentine pulpotomy outcomes in primary molars Wong, Bryan


Purpose: This study aimed to determine the effectiveness of Biodentine, a calcium-silicate material, as a pulpal medicament for primary molars requiring a pulpotomy procedure. Methods: A retrospective chart review was conducted on children who received a Biodentine pulpotomy procedure on one or more primary molar(s) while receiving dental rehabilitation under general anesthesia from January 1, 2013 to May 1, 2018. Five clinical and radiographic outcomes were used to determine the success of the pulpotomy. The teeth were evaluated at intermittent recalls for up to 30 months post-treatment. Survival curves of the Biodentine pulpotomized teeth were estimated by nonparametric maximum likelihood methods for interval censored data. Results: A total of 608 teeth from 208 children were evaluated over a 30-month post-treatment period. There was a total of twenty teeth with a failed pulpotomy procedure over the study period. Six teeth were identified as having both a clinical and radiographic failure. The remaining 14 failures were either a clinical or a radiographic failure – three were clinical failures, while eleven radiographic failures exclusively. A survival analysis curve indicated that the overall cumulative probability of survival at 30 months was 97.3% (95% CI = 83.7-99.2%) clinically, and 85.6% (95% CI = 76.3-93.7%) radiographically. Conclusions: Pulpotomy procedures on primary molars utilizing Biodentine as the pulpal medicament had favourable clinical and radiographic results up to 30 months.
