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.
本研究的目的是报告在三年期间对38例使用MTA进行根尖诱导成形术的临床和影像学评估情况。38例需要牙髓治疗的牙根未发育完成的牙齿，在使用牙胶尖充填之前，先用MTA形成根尖屏障进行治疗。对这些牙齿进行了临床和影像学评估。结果表明，使用MTA进行根尖诱导成形术是一种可预测的方法。特别是，达到根尖屏障所需的就诊次数和总时间明显少于使用氢氧化钙的传统技术。术前根尖周透射区的存在对治疗结果没有影响。MTA有望成为氢氧化钙的可行替代物以实现根尖封闭，并且使用MTA时，达到成功根尖屏障所需的就诊次数可能会显著减少。术前根尖周透射区的存在不影响治疗结果或治疗方案。
