未治疗根管可能对根管治疗的预后具有直接影响。这篇横向研究的目的是为了评估遗失根管与经牙髓治疗牙齿尖周损伤之间的关系。

未治疗根管可能对根管治疗的预后具有直接影响。这篇横向研究的目的是为了评估遗失根管与经牙髓治疗牙齿尖周损伤之间的关系。

研究通过5名不同的观察者对来自于8个健康中心自2018年1月至12月间的1160例已存CBCT影像进行分析。在20,836颗牙齿样本中(27,046 roots)共有2305颗牙齿已行牙髓治疗。评估所有经牙髓治疗牙齿是否存在遗失根管和尖周损伤。采用z test for proportions评估各组间差异,并计算比值比以分析遗失根管和损伤之间的联系。显著性水平设置为P < .05。

结果显示,遗失根管的发生率为12.0%,并且82.6%的病例中牙齿含未治疗根管与尖周损伤存在一定的联系。牙根遗失根管发生率最高的为上颌第一磨牙的近颊根管(62.8%),与尖周损伤存在联系的病例比例达到75.2%。上颌磨牙近颊根存在遗失根管更可能与尖周损伤相关的比例是所有根管均识别并治疗上颌磨牙的3.1倍。

结论:这篇研究的结果显示,未治疗根管与尖周损伤的存在具有一定的联系,表明遗失根管对治疗预后具有显著影响。
