J Endod:下颌前磨牙的根面沟和复杂牙根形态分析

2020-06-29 lishiting MedSci原创

下颌前磨牙通常含有一个牙根和一个根管。不同的研究显示,超过30%的下颌前磨牙含有不止一个根管,超过24%的下颌前磨牙具有C形根管。这篇研究的目的是为了评估以色列人群的牙根解剖和复杂根管形态的发生率。

下颌前磨牙通常含有一个牙根和一个根管。不同的研究显示,超过30%的下颌前磨牙含有不止一个根管,超过24%的下颌前磨牙具有C形根管。这篇研究的目的是为了评估以色列人群的牙根解剖和复杂根管形态的发生率。

研究共评估了1,020名以色列患者的CBCT影像结果。共检测了1,835颗下颌第一前磨牙和1,678颗第二下颌前磨牙。记录和评估不规则牙根解剖和不同的根管形态。

结果显示,下颌第一前磨牙和第二前磨牙复杂牙根形态(types II - VIII)的整体发生率分别为21%和2.8%。下颌第一前磨牙和第二前磨牙复杂牙根形态的双侧发生率分别为46%和29%。下颌第一前磨牙和第二前磨牙根面沟伴随复杂牙根形态的发生率分别为48%和36%。性别和发生的象限之间未见显著性差异。然而,在含有根面沟的下颌前磨牙中更易出现复杂根管形态。

结论:复杂根管形态更常发生于以色列人群的下颌第一前磨牙。在下颌第一和第二前磨牙中根面沟的存在与复杂根管形态具有显著关联性。
