Biodentine™ Pulpotomy in Stage I primary Molars: A 12-month Follow-up

AIM: This study aims to evaluate, over 12 months of clinical and radiographic follow-ups, the performance and outcomes of Biodentine™ pulpotomy in stage I primary molars. MATERIALS AND METHODS: A total number of 20 stage I primary molars requiring pulpotomy were selected from eight healthy patients aged between 34 and 45 months. Patients presenting a negative attitude toward dental treatment on the dental chair were scheduled for dental treatments under general anesthesia. Pulpotomy with Biodentine™ as a pulp-dressing material was performed on all selected molars. The patients were called back at 1 and 3 months for clinical follow-ups, then at 6 and 12 months for clinical and radiographic follow-ups. Data were tabulated according to follow-up intervals and occurrence of any changes in root maturation, pulp canal obliteration (PCO), periodontal ligament space (PLS), and bone or root lesion. RESULTS: No statistically significant differences were recorded at 1, 3, 6, and 12 months. There was a statistically significant increase in number of roots with closed apices from six roots at 6 months to 50 roots at 12 months (p < 0.0005) and the PCO was present in all 50 roots at 12 months, after it was present in 36 roots only at 6 months (p = 0.0001). CONCLUSION: This is the first randomized clinical trial that evaluates the performance of Biodentine™ as a pulp-dressing agent in stage I primary molar pulpotomy over 12 months of follow-up. Contrary to previous studies, the present work highlights the continued root formation and apical closure (AC) in pulpotomized immature primary molars.
