Clinical and Radiographic Evaluations of Biodentine™ Pulpotomies in Mature Primary Molars (Stage 2)

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.

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).

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.

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.

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.
