The number of overlapped and unreadable surfaces occurring on bitewing radiographs of 1,417 children participating in a clinical trial was recorded. Of erupted surfaces, only 73.3% were completely visible to both participating examiners. Interexaminer and intraexaminer reproducibility ratios were calculated according to the F.D.I. recommendations. The ratios obtained in the present study ranged from 0.06 to 0.36. Almost 57% of approximal cavities were diagnosed on radiographic examination only: 21% were diagnosed clinically, but were not apparent on the radiographs.
记录了参与一项临床试验的1417名儿童的咬合翼片上出现的重叠和无法读取的表面数量。在已萌出的表面中，只有73.3%的表面对两位参与检查的医生来说是完全可见的。根据国际牙科联合会（F.D.I.）的建议计算了检查者间和检查者内的重复性比率。本研究中获得的比率范围为0.06至0.36。几乎57%的邻面龋仅通过X线检查诊断：21%通过临床诊断，但在X线片上不明显。
