Abstract
INTRODUCTION: This study aimed to assess the outcome of partial pulpotomy using mineral trioxide aggregate (MTA) compared with calcium hydroxide (CH) in mature cariously exposed permanent molars. METHODS:Fifty permanent molar teeth with carious exposures in 50 patients >20 years old were included. Preoperative pulpal and periapical diagnosis was established based on a history of presenting pain, results of cold testing, and radiographic findings. After informed consent, the tooth was anesthetized, isolated via a dental dam, and disinfected with 5% sodium hypochlorite before caries excavation. Partial pulpotomy was performed by amputating 2 mm of the exposed pulp, hemostasis was achieved, and the tooth was randomly assigned for the placement of either white MTA (White ProRoot; Dentsply, Tulsa, OK) or CH (Dycal; Dentsply Caulk, Milford, DE) as the pulpotomy agent. Postoperative periapical radiographs were taken after placement of the permanent restoration. Clinical and radiographic evaluation was completed after 6 months and 1 and 2 years postoperatively. Statistical analysis was performed using the Fisher exact test. RESULTS: Clinical signs and symptoms suggestive of irreversible pulpitis were established in all teeth. Immediate failure occurred in 4 teeth. At 1 year, MTA showed a higher tendency toward success compared with the CH group, and the difference was statistically significant after 2 years (83% vs 55%, P = .052 at 1 year; 85% vs 43%, P = .006 at 2 years). Sex did not have a statistically significant effect on the outcome. CONCLUSIONS: MTA partial pulpotomy sustained a good success rate over the 2-year follow-up in mature permanent teeth clinically diagnosed with irreversible pulpitis. More than half of the CH cases failed within 2 years.
