Biodentine Pulpotomies on Permanent Traumatized Teeth with Complicated Crown Fractures

Introduction: The aim of this multicentric prospective study was to evaluate the clinical and radiographic outcomes of Biodentine (BD) pulpotomies on permanent teeth with complicated crown fractures. Methods: This study was carried out in 2 hospital-based dental departments in Quebec, Canada. Children seeking emergency care after trauma to anterior permanent teeth were invited to participate in this study. The treatment outcome was assessed clinically and radiographically at 1 week and 1, 3, 6, 12, 18, and 24 months after treatment. Results: Forty-five patients between the ages of 8 and 16 years (mean, 10.8 +/- 2.4) were included in this study. Fifty-one teeth were treated with a BD pulpotomy. The study showed a survival rate of 100% and a success rate of 91%. Four failures were noted at 1-, 6-, and 15-month follow-up, and the teeth were subsequently treated with either conventional root canal therapy or regenerative endodontic procedure. Dental sensitivity to cold reported by patients reduced over time, and more teeth responded normally to pulp vitality tests during the course of this study. Slight discoloration was noted on 8 teeth (17%). Radiographic outcomes showed dentinal bridge formation in 91 % of cases, and all immature teeth showed continued root formation. Conclusions: BD is a suitable material for pulpotomies on anterior permanent teeth with complicated crown fractures. It may be a good alternative to mineral trioxide aggregate pulpotomies because it does not cause significant discoloration, and it allows root maturation.
