口腔显微镜定位上颌磨牙近中颊根第二根管的效果评价
|
Abstract:
摘要 目的: 评价口腔显微镜定位上颌磨牙近中颊根第二根管的效果。方法: 收集符合条件的离体上颌磨牙80颗,使用CBCT检测MB2根管及分型.分别记录肉眼和口腔显微镜检测MB2的发现率;与CBCT所得结果做比较,对比肉眼直视和显微镜发现MB2的准确性,并分别对假阳性和假阴性的根管类型进行分析。结果: CBCT下MB2发生率51.25%。显微镜对MB2的发现率(42.50%)显著高于肉眼(26.25%),同时显微镜灵敏度高,假阳性率和假阴性率均显著低于肉眼,准确性在不同牙位未见显著差异。然而部分椭圆形根管口的MB2在显微镜下仍难以判断。结论: 显微镜的应用可以提高根管定位的精准度,在椭圆形根管上,显微镜和CBCT的联合应用具有较高的临床价值
