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

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.

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.

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).

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.
