目的分析锥形束CT在口腔内科临床诊断治疗中的应用。方法选择根管再治疗患者30例和根尖周炎患者40例,全部患者分别给予锥形束CT检查和传统X线片检查,对两种检查结果进行观察比较。结果根管再治疗患者传统X线片检查的准确率仅为13.3%(4/30),而锥形束CT技术检查的准确率却高达100.0%(30/30)。根尖周炎患者X线平片的诊断准确率为75.0%(30/40),而锥形束CT技术的诊断准确率则为100.0%(40/40)。锥形束CT检测根管再治疗患者以及根尖周炎患者的准确率显著高于传统X线片检查(P<0.05)。结论在口腔内科的临床诊断治疗中,应用锥形束CT检查,能对三维立体影像进行清晰显示,进而对牙体牙髓病变的程度、性质、范围以及位置进行整体、准确和直观地了解,使根尖周炎病和牙体牙髓病的临床诊断准确性和临床疗效得以有效提升,具有临床推广价值和应用价值。
Objective To analyze the application of cone beam CT in the clinical diagnosis and treatment of oral medicine. Methods 30 patients with root canal re-treatment and 40 patients with periapical periodontitis were selected. All patients were cones-beam CT and conventional X-ray examination. The results of the two tests were compared. Results The accuracy of conventional X-ray examination of root canal re-treatment was only 13.3% (4/30), but the accuracy of cone beam CT examination was as high as 100.0% (30/30). The diagnostic accuracy rate of radiofrequency with periapical periodontitis was 75.0% (30/40), while the diagnostic accuracy of cone beam CT was 100.0% (40/40). The accuracy of cone-beam CT in root canal re-treatment patients and patients with periapical periodontitis was significantly higher than that of conventional radiography (P <0.05). Conclusion In the clinical diagnosis and treatment of oral medicine, cone beam computed tomography (CT) examination can clearly display the three-dimensional images and then make a complete, accurate and intuitive understanding of the degree, nature, extent and location of dental pulp lesions. So that periapical disease and dental pulp disease clinical diagnosis accuracy and clinical efficacy can be effectively improved, with clinical and clinical value and application value.
