To investigate the outcome of endodontic microsurgery and analyze the potential prognostic factors, and to evaluate the value of surgical classification by Kim and Kratchman.
Collecting clinical examination and radiographical examination of endodontic microsurgery cases (which were followed up at least 1 year), which were classified according to Kim and Kratchman, and we analyzed the outcome of endodontic microsurgery and its potential prognostic factors.
302 patients (400 teeth) who received endodontic microsurgery were included. The one year success rate of endodontic microsurgery was 94.25%. Different classification had significant influences on the outcome of endodontic microsurgery (<0.05), and the success rate of class B and C were better than those of class D, E, and F. The position of teeth had significant influences on the outcome of endodontic microsurgery (<0.05). The success rate of maxillary teeth was higher than that of mandibular teeth. The success rate of anterior teeth was higher than that of posterior teeth (<0.05). The quality of root end filling and first or second surgery had no effect on the outcome (>0.05).
Endodontic microsurgery is an effective treatment method for saving affected teeth, and it can get a good result. Tooth position and classification are the potential prognostic factors. The surgical classification of Kim and Kratchman can help to predict the outcome of endodontic microsurgery.
探讨根管显微镜手术的疗效，并分析其潜在的预后因素，评估 Kim 和 Kratchman 手术分类的价值。
收集根管显微镜手术病例（至少随访 1 年）的临床检查和影像学检查资料，根据 Kim 和 Kratchman 分类进行分类，分析根管显微镜手术的疗效及其潜在的预后因素。
共纳入 302 例（400 颗牙）接受根管显微镜手术的患者。根管显微镜手术的 1 年成功率为 94.25%。不同分类对根管显微镜手术的疗效有显著影响（<0.05），B 级和 C 级的成功率优于 D、E 和 F 级。牙齿位置对根管显微镜手术的疗效有显著影响（<0.05）。上颌牙的成功率高于下颌牙，前牙的成功率高于后牙（<0.05）。根管充填质量和初次或二次手术对疗效无影响（>0.05）。
根管显微镜手术是保存患牙的有效治疗方法，可获得良好的效果。牙位和分类是潜在的预后因素。Kim 和 Kratchman 的手术分类有助于预测根管显微镜手术的疗效。
