An accident that can occur during endodontic treatment is perforation, which adversely affects the prognosis of the teeth. A restorative material should be easy to use, nonresorbable, biocompatible, esthetically pleasing, and should provide a complete seal. Mineral trioxide aggregate (MTA) is a relatively new material that is being used successfully to repair perforation. The purpose of this study was to perform a clinical and radiographical evaluation of the success rate of root perforation repairs using mineral trioxide aggregate. Based upon the results of this study, MTA is a suitable material for root perforation repair and can be used confidently.
根管治疗过程中可能发生的一种意外情况是穿孔，这会对牙齿的预后产生不利影响。一种修复材料应易于使用、不可吸收、具有生物相容性、美观，并应提供完全密封。三氧化矿物凝聚体（MTA）是一种相对较新的材料，已成功用于修复穿孔。本研究的目的是对使用三氧化矿物凝聚体修复牙根穿孔的成功率进行临床和影像学评估。基于本研究结果，MTA是一种适合牙根穿孔修复的材料，可以放心使用。
