J Endod:根尖和下颌管之间的关系:一项3组人群的CBCT观察比较

2018-04-28 lishiting MedSci原创

这篇研究的目的是通过锥形束CT(CBCT)影像分析观察3组不同人群下牙槽神经(IAN)相对于下颌磨牙根尖的位置差异,并评估位置(距离在1 mm或更少)接近IAN牙齿的比例。

这篇研究的目的是通过锥形束CT(CBCT)影像分析观察3组不同人群下牙槽神经(IAN)相对于下颌磨牙根尖的位置差异,并评估位置(距离在1 mm或更少)接近IAN牙齿的比例。

研究随机对CBCT影像(N = 1224, 以色列人= 408, 南韩人= 416, 印度人= 400)进行分析。通过图像软件计算牙齿距离下颌管的最短距离。

结果显示,平均距离为4.81 ± 2.15 mm。以色列人、南韩人及印度人的平均距离分别为60 ± 2.37 mm, 5.45 ± 2.13 mm和4.35 ± 1.76 mm。南韩人样本中的距离要显著大于以色列及印度人(P < .05)。以色列人中最接近下颌管的样本为6.6%,印度人为3%,南韩人为0.7%,它们之间具有显著性差异(P < .05)。

结论:虽然在不同人群中牙齿的解剖形态存在很大差异,但还没有研究调查不同人群中IAN相对于牙齿根尖的位置差异。这篇研究揭示了不同人群中IAN距根尖的距离以及牙齿接近IAN的比例均存在差异。

J Endod:上颌磨牙近颊第二根管在CBCT辅助下的发生率评估

许多上颌磨牙根管治疗失败的原因为遗漏了第二近颊根管(MB2)。多达95%的上颌磨牙存在MB2根管,但是这些根管在牙髓治疗过程中通常不好定位。额外的工具,例如:锥形束CT(CBCT)影像分析,可以帮助定位上颌磨牙的这些根管。因此,这篇研究的目的是为了评估在治疗上颌磨牙过程中使用CBCT的频率,并且评估其探查MB2根管的效果。
