J Endod:上颌磨牙近颊第二根管在CBCT辅助下的发生率评估

2018-04-17 lishiting MedSci原创

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。

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。

研究回顾性分析了华盛顿大学, Seattle, WA在2010年至2014年间上颌第一和第二磨牙的牙髓治疗记录、数码口内X线影像(如果有)和CBCT影像 (N=886)。通过统计学分析评估各组间的差异。

结果显示,总的来说,在上颌磨牙中存在MB2的发生率为55.8%,其中有11.7%是通过CBCT辅助检查发现。有16.5%的病例使用CBCT影像分析,并且再治疗病例使用的更多。有5.6%的病例在术前使用CBCT影像分析,并且数据显示,术前使用CBCT可以定位出更多的MB2根管。在没有全覆盖冠的第一磨牙中可以定位到更多的MB2。

结论:数据显示,CBCT影像分析是定位MB2根管的有效手段。基于此项研究结果,在治疗上颌磨牙时可以使用CBCT成像。
