摘要 目的:探讨首次根管治疗失败后进行根管再治疗的疗效,分析影响再治疗效果的因素。方法 :选择2014年1月—2015年12月期间在本院口腔科门诊就诊的138例152颗首次根管治疗失败后需进行根管再治疗的患牙,根据临床上常见的医源性因素和X线评判标准将152颗患牙分为4组。Ⅰ组:根管欠充填;Ⅱ组:根管漏充填;Ⅲ组:根管充填不严密;Ⅳ组:根管超充填。4组均伴有不同程度的根尖透射区。根据X线结合临床症状评价疗效。结果:152颗患牙根管再治疗成功123颗,成功率80.92%,Ⅰ、Ⅱ、Ⅲ、Ⅳ组治疗的成功率分别为88.71%、85.00%、75.00%和9.09%。结论:根管再治疗能取得较好的疗效,但其中根管超充填的再治疗失败率较高,体现了首次根管治疗的重要性。
