锥形束CT在根尖周病诊断中的临床价值研究

摘要/Abstract

摘要： ［摘要］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。

Abstract: Abstract: Objective To assess the diagnostic accuracy of cone beam computed tomography in comparison with radiography in detecting 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 detecting 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.
