摘要
目的比较根尖X线片(periapical radiograph,PR)与锥形束CT(cone-beam computed tomography,CBCT)在诊断根管治疗(root canal treatment,RCT)失败病例时的差异。方法回顾性分析RCT失败患牙的影像学资料,比较根尖X线片与CBCT诊断RCT失败病例的病因和病情的差异。结果共分析210颗RCT失败患牙的根尖X线片和CBCT资料,根管欠填和遗漏根管是导致RCT失败的主要原因。CBCT能更准确的判断根管充填质量和根折类型,CBCT对遗漏根管的检出率比根尖X线片高14.8%,对根折的检出率比根尖X线片高5.7%。结论 CBCT对RCT失败病例的病因和病情分析优于根尖X线片,能为根管再治疗的方案制定提供更有意义的参考。
Objective To compare the differences between periapical radiography（ PR） and cone-beam computed tomography（ CBCT） in diagnosing failure cases of root canal treatment（ RCT）. Methods The radiographic data of RCT failure cases were retrospectively analyzed. The differences between PR and CBCT in analyzing the pathogenesis and state of RCT failure cases were compared.Results A total of 210 RCT failure cases＇ PR and CBCT images were collected and analyzed. Under-filling teeth and missing root canals mainly accounted for the failure in RCT. CBCT could judge the quality of root canal filling and the type of root fracture more accurately. The detection rate of missing root canals of CBCT was 14.8%,higher than that of PR,and the detection rate of root fracture of CBCT was 5.7%,higher than that of PR. Conclusion CBCT images are better than PR in analyzing the pathogenesis and state of RCT failure cases,which will offer more significance in root canal retreatment.
