A report on the clinical and radiographic outcomes of 38 cases of apexification with mineral trioxide aggregate.

Abstract

The aim of the study was to report on the clinical and radiographic assessment of 38 cases of apexification using MTA over a three year period. Thirty-eight cases of immaturely developed teeth requiring endodontic therapy were treated using MTA to achieve an apical barrier prior to obturation with gutta-percha. The teeth were clinically and radiographically assessed. The findings indicate that apexification using MTA is a predictable procedure. In particular, the number of visits and the total time taken to achieve an apical barrier was markedly less than conventional techniques using calcium hydroxide. The presence of a preoperative periapical radiolucency had no effect on the outcome. MTA shows promise as a viable alternative to calcium hydroxide to achieve root-end closure and using MTA, the number of visits to achieve a successful apical barrier may be markedly reduced. The presence of preoperative periapical radiolucencies did not affect the outcome or the treatment protocol.
