MTA Pulpotomies: A Long-Term Case Series Outcomes Assessment of Complicated Crown Fractures.

Abstract

This retrospective case series describes the outcomes of anterior teeth with complicated fractures treated using mineral trioxide aggregate (MTA) in pulpotomy procedures. 33 teeth were treated with MTA pulpotomy procedures in an endodontic private practice. All patients had been referred to the practice for diagnosis and treatment of a pulpal exposure due to complicated crown fractures. The teeth were either recalled directly or "indirectly" by the referring dentist. Teeth recalled directly were categorized as healed, healing, non- surgical root canal treatment completed for either aesthetic or restorative reasons, or persistent disease. Teeth recalled indirectly were categorized as successful or failed. 27 teeth were available for recall; 20 teeth directly and 7 teeth indirectly. The mean recall for teeth recalled directly was 3.94 years and the mean recall for teeth recalled indirectly was 5.9 years. The recall range for teeth recalled directly was 0.51 to 10.49 years and for teeth recalled indirectly was 3.58 to 10.66 years. Of the cases available for direct recall, 13 of 20 teeth were healed positive to pulp tests, 4 of 20 teeth were healed negative to pulp tests and 3 of 20 teeth had non-surgical root canal treatment completed. 15 of the 20 teeth recalled directly where discolored. 7 of 7 teeth recalled indirect were successful as determined by the radiographs and a report from the restorative dentist. MTA is a viable alternative to calcium hydroxide for pulpotomies.
