Endodontic treatment for necrotic immature permanent teeth using MTA and calcium hydroxide. A retrospective study
Journal Title: RSBO - Year 2013, Vol 10, Issue 2
Abstract
Introduction: Endodontic treatment of young permanent teeth with incomplete root formation and necrotic pulp has been a challenge for the dentist. It is necessary to induce the formation of apical barrier (apical plug), enabling the complete root canal filling. Objective: This retrospective clinical study compared the protocols for treatment of teeth with incomplete root formation, using calcium hydroxide (CH) or mineral trioxide aggregate (MTA). Material and methods: 28 patients with incomplete root formation have undergone root canal treatments in the period from 2000 to 2009 were selected. The procedures for cleaning, shaping and intracanal medication (CH paste) were performed in a standardized manner. In 13 patients, after using the CH paste (14 days), apical plugs with MTA were made. In the remaining 15 teeth monthly exchanges with CH paste were executed until it was observed radiographically the formation of the apical barrier. In all cases the canals were filled conventionally with gutta-percha and sealer. Initially, follow-ups were made on a quarterly and semiannually at the end of first year. Results: All apical lesions showed apical healing between 4 and 13 months after starting treatment. There was not noted the continuing process of root formation. Conclusion: It was concluded that the treatment of teeth with incomplete root formation and necrotic pulp with the use of MTA as apical plug has the same clinical results compared with the use of CH, with the advantage of less clinical time.
