Three hundred thirty cases were selected from an endodontic practice. Postoperative and recall radiographs of each case were examined by four endodontists for an interpretation of treatment success or failure. One hundred eighteen cases were examined a second time by each endodontist. Initial analysis showed substantial inconsistency in both inter- and intraobserver interpretation. The cases were then categorized by average radiographic density differences within radiograph sets, anatomic location of the treated tooth, technical compatibility within radiograph sets, and by length of time between postoperative and recall radiographs. It appears that these factors do not affect reliability of success/failure interpretation.
从一家牙髓病治疗诊所选取了330个病例。四位牙髓病医生对每个病例的术后及复诊X光片进行检查，以判断治疗成功与否。每位牙髓病医生对118个病例进行了二次检查。初步分析显示，观察者之间和观察者内部的解读存在很大不一致性。然后，根据X光片组内的平均放射密度差异、治疗牙齿的解剖位置、X光片组内的技术兼容性以及术后X光片和复诊X光片之间的时间长度，对病例进行了分类。看来这些因素并不影响成功/失败解读的可靠性。
