目的：对比研究锥形束CT和根尖片对根尖周病的诊断价值。方法分别对35位患者，总共41颗诊断为根尖周病的患牙用锥形束CT和根尖片进行扫描，阅片后作出判断。结果通过锥形束CT发现有37颗牙存在根尖阴影，而根尖片仅发现27颗牙存在根尖阴影。结论锥形束CT比根尖片诊断根尖周病的准确度高，临床上锥形束CT 可以辅助诊断疑难病例。

Objective To assess the diagnostic accuracy of cone beam computed tomography in comparison with radiography in de -tecting periapical lesions .Methods 35 patients (41 teeth) diagnosed with periapical lesions were selected .Digital radiographs and CBCT images were used to scan the teeth , and the diagnostic accuracy was judged afterwards .Results The overall accuracy for detec-ting periapical lesions was higher for CBCT compared with the digital radiographs .According to the CBCT images , 37 teeth showed periapical shadows , while only 27 teeth showed periapical shadows by digital radiographs .Conclusions The CBCT technique has higher accuracy than digital radiographs , which can help diagnose intractable cases in clinic .
