J Endod:高分辨率小视野CBCT对于检测垂直性根裂的准确性:一项体内研究

2020-06-04 lishiting MedSci原创

这篇体内研究的目的是为了比较小视野CBCT与常规根尖周X线片(CPR)对于垂直性根裂(VRF)诊断的准确性,并采用手术探查(ES)作为参考标准。

这篇体内研究的目的是为了比较小视野CBCT与常规根尖周X线片(CPR)对于垂直性根裂(VRF)诊断的准确性,并采用手术探查(ES)作为参考标准。

研究纳入了85颗怀疑为VRFs牙齿的82例口腔病例,内容涵盖了CPR, CBCT和ES检查。由2名观察者独立评估CPR和CBCT影像,观察是否存在根裂,ES结果作为参考标准。获取诊断的敏感性、特异性、准确性和ROC曲线值。也评估单根和多根牙对诊断以及临床症状与存在VRFs之间联系的影响。

结果显示,手术探查发现85颗牙齿中有64颗存在VRFs (75.3%),其中62.5%为多根牙,并且76.6%存在根管桩。CBCT的敏感性和准确性(65.6% and 64%)要高于CPR (27.3% and 40.5%)。CPR和CBCT对单根牙的诊断准确性要高于多根牙。叩诊疼痛、局限性牙周袋和牙齿松动与VRFs的存在相关(P < .05; OR = 4.15, 13.5 and 4.1, respectively)。

结论:CBCT对VRFs诊断的准确性效果较差,虽然其准确性高于CPR。存在根管桩的多根牙可能会限制其诊断价值。
