ABSTRACT
PURPOSE: The purpose of this study was to assess the outcome of coronal pulpotomy using mineral trioxide aggregate (MTA) in mature and immature teeth with symptoms indicative of irreversible pulpitis. METHODS: Fifty permanent molars with symptomatic irreversible pulpitis were divided into two groups according to complete or incomplete radicular growth (25 teeth in each group). Coronal pulpotomy was performed with MTA. Clinical follow-up evaluations were scheduled at the third, sixth, ninth, 12th, 18th, and 24th months. Follow-up radiographs were taken at the sixth, 12th, 18th, and 24th months. Pain levels were scored preoperatively and two days post-treatment. RESULTS: At two years of recall, 10 patients were lost to follow-up and the success of molars with complete or incomplete radicular growth were 100 percent and 95 percent, respectively. All teeth with periapical rarefaction were present preoperatively and showed complete radiographic healing. Radiographic evidence of dentin bridge formation was discernable in 31 of 38 cases. CONCLUSIONS: Full coronal pulpotomy using mineral trioxide aggregate was successful in controlling pain and any infections after two years in 39 of 40 teeth regardless of whether they had immature or mature roots.
