Objective: This study evaluated the effectiveness of Platelet Rich Plasma (PRP), Platelet Rich Fibrin (PRF) and Mineral Trioxide Aggregate (MTA) as direct pulp capping materials in patients with carious pulp exposure using cone beam computed tomography. Methods: This parallel, triple blinded, randomised trial was done on 30 permanent posterior teeth chosen as candidates for direct pulp capping based on stringent inclusion and exclusion criteria. The samples were allocated based on sequentially numbered opaque sealed envelope method into three groups: MTA, PRP and PRF for direct pulp capping. The treated teeth were restored with Glass Ionomer cement liner and light-cured resin composite. Patients were followed up for a period of 12 months. Statistical analyses were performed with statistical software SPSS version 25. Data were analysed for normality using Shapiro Wilk’s test. Dentine bridge volume analysis across the groups were done using Kruskal Wallis test with the significance level at P=0.05. As the test revealed a significant difference, post hoc analysis was done with Dunn test. Results: CBCT analysis revealed that the volume of dentine bridge formed by PRP and PRF was significantly higher than the volume of dentine bridge formed by MTA (P<0.001; CI: 90%). There was no significant difference in the efficacy between the three direct pulp capping agents based on clinical assessment. A total of 27 teeth (90%) showed positive response to pulp sensibility testing and evidence of dentine bridge formation in radiograph at 12 months. No adverse events were encountered. Conclusion: Platelet concentrates could be the future of vital pulp therapy for adult permanent teeth with reversible pulpitis. (EEJ-2021-05-078)
