Introduction The preservation of the integrity and health of primary teeth and their supporting tissues is of great importance in maintaining arch length space, mastication, speech, and esthetics. A pulpotomy is a common therapy performed on a primary tooth presenting reversible pulpitis or a traumatic pulp exposure, allowing its conservation on the arch until its loss. Aim The study aims to clinically and radiographically evaluate the rates of success and efficacy of Biodentine™ as pulpotomy medicament exclusively on deciduous molars with complete roots formation (stage 2). Materials and methods A total number of 75 primary molars in stage 2 of formation were selected to undergo pulpotomy treatment. All teeth were restored with a stainless-steel crown. The clinical success was evaluated at 1, 3, 6 and 12-month intervals. The radiographic follow-up evaluations were at 6 and 12 months. The resulting data were tabulated and statistically analyzed. Results Among the 75 teeth treated with Biodentine™, one tooth revealed abnormal mobility and tenderness to percussion at the end of the 1st month. PLS widening and the bone lesion was not seen in any of the 74 remaining cases. Forty teeth (54.1%) showed pulp canal obliteration (PCO), and none of the cases developed a draining sinus or had increased mobility. At the end of the 1-year follow-up, the clinical and radiographic success rates were 98.7% and 100%, respectively. Conclusion Pulpotomies performed with Biodentine™ on stage 2 primary molars were generally very satisfactory and fulfilled all requirements, covering all needs. This innovative bioactive medicament seems to be a “heroic” material. The excellent outcomes of the present study are indicative that Biodentine™ is a promising biomaterial to promote pulp repair after pulpotomy in clinical practice.

A bstract 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.
