Evaluation of partial pulpotomy treatment in cariously exposed immature permanent molars: Randomized controlled trial

This study aimed to assess the outcomes of partial pulpotomy treatments using different biocompatible materials which were Biodentine^®, mineral trioxide aggregate (MTA), and calcium hydroxide (CH) in cariously exposed pulp tissue in immature permanent molars.

Fifty-four teeth of 50 patients, which had cariously pulp exposures were randomly divided into Biodentine^®, MTA, and CH groups for partial pulpotomy treatments and finally restored with stainless steel crowns at the same appointment. Clinical and radiographical success was evaluated by the absence of any clinical and radiographical signs and symptoms for 12 months. Also, Image J was used for the quantitative assessment of length developments for mesial and distal roots. P value of less than 0.05 was considered statistically significant.

Partial pulpotomy treatments showed high overall success rate (87%). On the other hand, Biodentine and MTA showed higher success rates compared to CH without any statistical significance (P = 0.09). Besides, mesial and distal root lengths displayed a continuous and significant increase in each group at sixth month follow-up (P = 0.01; P = 0.03).

Favorable results demonstrated that Biodentine, MTA, and CH might be recommended as suitable agents for partial pulpotomy treatment in cariously exposed immature molars with clinical diagnosis of normal pulp or reversible pulpitis.
