Objective: The present study aimed to explore the survival rate after 3 years of partial pulpotomy in adult permanent teeth with carious pulp exposure, using ProRoot MTA® and Biodentine™. Materials and Methods: This study is a follow-up to a previously reported 1-year outcome of a randomized clinical trial investigating the non-inferiority of Biodentine compared to MTA for partial pulpotomy in adults’ permanent teeth with carious pulp exposure (Thai Clinical Trials Registry: TCTR20171228003). All 58 participants whose teeth were treated for at least 3 years were contacted for follow-up, which included clinical examinations, radiographic evaluations, and a patient satisfaction survey. Results: Forty-eight patients (82.8% recall rate) were followed up for an average of 40.95 ± 4.24 months. The overall cumulative pulp survival rate was 78.7%, with 87.4% for ProRoot MTA® and 70.7% for Biodentine™, showing no significant difference between the materials. The highest frequency of failure occurred between 24 and 35 months. Discoloration of teeth was observed in both groups, 42.1% (8/19) in teeth treated with ProRoot MTA® and 10% (2/20) in teeth treated with Biodentine™, showing a statistically significant difference (p = 0.031). Acceptable restorations were present in 74.4% of patients, and most patients were very satisfied with the treatment. Conclusion: The cumulative pulp survival rate for adult permanent teeth with carious pulp exposure was 78.7% after at least 3 years of partial pulpotomy, with no significant difference between ProRoot MTA® and Biodentine™. Since treatment failures were most frequent between 24 and 35 months, clinical and radiographic follow-ups are recommended for at least 3 years. For patients with significant tooth structure loss who have not received full coverage restoration, annual follow-ups are advised to assess restoration quality.Downloads
