两种根管治疗方法的效果比较分析

目的探讨根管治疗的最佳方法。方法选择有记载、有随访的根管治疗病例132例共146颗牙齿,根据所采用的手术方法分为3组,分别是根管充填术＋根尖切除术组79例,根尖切除术＋倒充填组36例,根管充填术＋根尖切除术＋倒充填组31例,分别对3组治疗效果进行比较。结果 146颗牙齿中,治愈109颗,好转18颗,失败19颗,总成功率86.9%,3组的成功率分别是根管充填术＋根尖切除术组89.9%（71/79）,根尖切除术＋倒充填组83.3%（30/36）,根管充填术＋根尖切除术＋倒充填组83.9%（26/31）。根管充填术＋根尖切除术组疗效优于另外两组（P〈0.05）。结论牙根长度足够的情况下采用根管外科治疗顽固性根尖病变,是一种简单、经济、有效的辅助治疗手段,其中根管充填术＋根尖切除术术后反应小,成功率高,可作为临床首选方法。
