摘　　要：目的比较全景片和锥形束CT（CBCT）对AngleⅡ~2错牙合畸形患者的髁突骨质改变检测的准确性,为临床合理运用X线片进行诊断提供依据。方法 60例AngleⅡ~2错牙合畸形患者根据临床检查分为有症状组（A组）和无症状组（B组）,分别对双侧颞下颌关节进行全景片和CBCT检查,对髁突骨质改变进行检测,并对二者差异进行统计学分析。结果 CBCT对髁突骨质改变的诊断一致性较高,全景片一致性诊断存在一定差异;以CBCT对髁突骨质改变的检测结果为金标准,该两组与CBCT检测结果比较,A组全景片正确诊断率为66.7%,B组全景片正确诊断率为85.7%。结论全景片在筛选AngleⅡ~2错牙合畸形患者TMD的临床诊断中具有一定的应用价值,但其灵敏度低于CBCT。Objective To compare the panoramic radiography with cone-beam computed tomography（CBCT） in diagnostic accuracy of morphological changes of temporal-mandibular joints （TMJ） in adult patients with Angle Ⅱ 2 malformations. Methods 60 cases of Angle Ⅱ2 malformations were divided into two groups：A, the asymptomatic group and B. the symptomatic group. Bilateral TMJs were examined by panoramic radiography and CBCT, and morphological changes of the condyles were detected. Data were statistically ana- lyzed. Results CBCT was better than panoramic radiography in the consistency of diagnosis. Taking CBCT test as the gold standard, the diagnostic accuracy of panoramic radiography was 66.7% in group A and 85.7% in group B. Conclusion Panoramic radiography can be applied in the diagnosis of morphological changes of TMJs in adult patients with Angle 112 malformations, but its sensitivity is lower than CBCT.
