Abstract

Objective: To compare the clinical effectiveness of Bio dentine and Mineral Trioxide Aggregate (MTA) as direct pulp capping agents in permanent teeth with carious pulp exposure.
Methodology: This quasi-experimental study was conducted in Department of Operative Dentistry at de’ Montmorency College of Dentistry from Jul 2022 to Jan 2023 and included 150 patients divided into two groups of 75 each. Patients aged 18-45 with permanent teeth exhibiting deep carious lesions, but were vital, were selected. Group I received MTA while Group II received Bio dentine. Direct pulp capping was performed under local anesthesia. Clinical and radiographic evaluations were conducted at a three-month follow-up, focusing on the absence of pain, pulp vitality, and periapical radiolucency. The data were analyzed using SPSS and Chi-square’s test was used to compare categorical variables.
Results: Out of 150 patients, 55% were male and 45% were female, with a mean age of 30±7.9 years. Group I (MTA) showed a success rate of 76%, with 57 teeth showing no periapical radiolucency. Group II (Bio dentine) exhibited a significantly higher success rate of 96%, with 72 teeth showing no periapical radiolucency (p=0.001). Statistical analysis showed no significant impact of age (p=0.36) or gender (p=0.19) on treatment efficacy.
Conclusion: Bio dentine demonstrated superior clinical performance compared to MTA in direct pulp capping, suggesting it as a preferable material due to its higher success rate and better handling properties. Further studies on long-term outcomes and cost-effectiveness are recommended.
