Evaluation and comparison of mineral trioxide aggregate and biodentine in primary tooth pulpotomy: Clinical and radiographic study.

OBJECTIVES: Pulpotomy is the common therapy for cariously exposed pulps in symptom-free primary molar teeth. For many years, researchers have searched for an ideal material that allows regeneration of the residual pulp. The purpose of this study was to evaluate the efficacy of mineral trioxide aggregate (MTA), Biodentine as a pulpotomy medicament in primary teeth, both clinically and radiographically. MATERIALS AND METHODS: A total of 25 children (50 human primary molar teeth) aged between 5 and 9 years were selected in this randomized clinical study. The patients were randomly assigned to receive the pulpotomy medicaments in either [Group 1]: MTA or [Group 2]: Biodentine. All pulpotomized teeth were restored with stainless steel crowns and evaluated clinically and radiologically at 1, 3, 6 and 12 months. Statistical analysis using Mann-Whitney U test and Fisher's exact test, and chi-square test was performed to determine the significant differences between the groups. RESULTS: Clinical and radiological success rates were 96 and 80% in Group 1 and 96 and 60% in Group 2, respectively. There were no significant differences between the groups (P > 0.05). The radiographic success rates decreased in the controls, but there were no significant differences. CONCLUSION: Biodentine showed similar clinical and radiographic results as MTA in the 12-month evaluation and can be safely used as a pulpotomy medicament.
