摘　　要：目的对比牙周内窥镜与CBCT诊断牙根纵裂(vertical root fracture,VRF)的准确性,以评价牙周内窥镜在诊断伴有深牙周袋VRF中的应用价值。方法纳入临床症状高度怀疑为VRF但根尖片无法确诊的患牙56颗,分别进行CBCT和牙周内窥镜检查,评估两种方法对VRF的诊断效果。结果在56颗疑似VRF患牙的诊断中,牙周内窥镜的正确指数为83.7%,CBCT正确指数为53.1%。其中,在对43颗根管治疗后疑似VRF患牙的诊断中,牙周内窥镜的正确指数为92.3%,而CBCT仅为41.0%。两种方法诊断VRF的结果差异具有统计学意义(P<0.05)。结论牙周内窥镜在诊断伴深牙周袋的隐蔽性VRF,尤其是根管治疗后的VRF,其准确性优于CBCT,为临床医师提供了一个可靠的检查手段。Objective To evaluate the application value of periodontal endoscopy in the diagnosis of vertical root fracture(VRF) by comparing the accuracy of periodontal endoscopy and CBCT in the diagnosis of VRF with deep periodontal pocket.Methods Fifty-six teeth with high suspicion of VRF based on clinical symptoms but undiagnosed by periapical film were included. CBCT and periodontal endoscopy were performed respectively to evaluate the diagnostic effects on VRF.Results In the diagnosis of the 56 suspected VRF teeth, the correct index of periodontal endoscopy was 83.7%, and the correct index of CBCT was 53.1%. Among them, in the diagnosis of 43 suspected VRF teeth after root canal treatment, the correct index of periodontal endoscopy was 92.3%, while that of CBCT was only 41.0%. There was significant difference between the two methods in the diagnosis of VRF(P<0.05).Conclusion Periodontal endoscopy is more accurate than CBCT in diagnosing concealed VRF with deep periodontal pocket, especially for VRF teeth after root canal treatment, which provides a reliable examination method for clinicians.
