The purpose of this study was to compare Biodentine and mineral trioxide aggregate (MTA) for direct pulp capping in young permanent molars by clinical and radiographic evaluation in 7- to 9-year-old children.


In 50 patients, 29 patients with bilateral asymptomatic first permanent molars with carious involvement were selected. According to split mouth design, these patients were then divided into 2 groups, Biodentine group (right side) and MTA group (left side). The pulp-capping procedure was performed by using Biodentine and MTA in 58 asymptomatic bilateral permanent molars with pulp exposure. At each recall (baseline, 6 and 12 months), treatment outcome was assessed clinically through pulpal sensitivity tests as well as radiographically to evaluate dentin bridge formation.


The study reported 100% success rate with both Biodentine and MTA at baseline and 6- and 12-month follow-up on the basis of clinical and radiographic parameters. These findings were statistically non-significant (P < .05) between both groups (Biodentine and MTA). Radiographically, dentin bridge formation was not evident with both groups at baseline, but it was evident after 6- and 12-month follow-up. These findings were statistically non-significant (P < .05) in both Biodentine and MTA groups.


This study reported 100% success rate with both MTA and Biodentine when used as direct pulp-capping agent in first permanent molars in 7- to 9-year-old children. The major limitations of the study were smaller sample size and short follow-up period.
