This research found a substantial interobserver disagreement existing in endodontic success/failure interpretation from periapical radiographs. The diagnostic variability appears to be independent of the anatomic location of the endodontically treated tooth (even though it seems less for mandibular teeth), as well as it appears to be independent of the time interval between post-operative and recall radiographs. Extremely significant has also been the fact that an important percentage of observers have contradict themselves in the interpretation of the same radiograph.
本研究发现，根尖片对根管治疗成功/失败的解读存在显著的观察者间差异。这种诊断变异性似乎与接受根管治疗牙齿的解剖位置无关（尽管下颌牙齿的变异性似乎较小），并且似乎也与术后片和复查片之间的时间间隔无关。同样极为显著的是，相当一部分观察者在解读同一张X线片时自相矛盾。
