摘　　要：目的探讨口腔颌面锥形束CT(conebeamcomputedtomography,CBCT)应用于牙外伤侧方脱位诊断中的准确性研究。方法选取2022年6月—2024年6月于中山市口腔医院就诊的50例牙外伤侧方脱位患者为研究对象,所有患者均在初次就诊时拍摄根尖片及口腔CBCT,回顾患者就诊资料,请一位经验丰富的医生读片,从根尖片及口腔CBCT检查结果中判断是否存在侧方脱位,根尖片检查设为对照组,口腔CBCT检查设为观察组,绘制ROC曲线,比较两种检查方法在牙外伤侧方脱位患者诊断中的准确性。结果观察组侧方脱位检出率显著高于对照组(P<0.05)。结论对于牙外伤侧方脱位患者,CBCT能够为明确诊断提供更有利的依据,提高牙外伤诊断类型的准确性,帮助医生确定复位固定时间。Objective To investigate and research accuracy of cone beam computed tomography(CBCT)in diagnosis of lateral dislocation caused by dental trauma.Methods The paper reviewed and analyzed clinical data of 50 patients with lateral dislocation caused by dental trauma in Zhongshan Stomatological Hospital from June 2022 to June 2024.Root apex radiographs and oral CBCT were taken for all patients at initial admission.An experienced doctor reviewed medical data of patients,read radiographs to determine lateral dislocation based on the results of root apex radiographs and oral CBCT examinations.Patients examined with root apex radiographs were included in the control group and those with oral CBCT examinations in the observation group.Accuracy of two examination methods in diagnosis of lateral dislocation caused by dental trauma was compared based on ROC curves.Results Detection rate of lateral dislocation in the observation group was significantly higher than the control group(P<0.05).Conclusion CBCT can provide favorable basis for clear diagnosis,improve accuracy of dental trauma diagnosis types of patients with lateral dislocation,and help doctors determine reduction and fixation time.
