Diagnosis of early occlusal caries has proved more difficult than that affecting smooth or approximal surfaces. With time, this type of lesion has come to form a greater proportion of caries as a whole and its accurate diagnosis is consequently becoming more important. The most widely used methods of diagnosis are visual inspection and bitewing radiography but the value of both of these for occlusal caries has been questioned. The aim of this study was to investigate the validity of diagnosis using each of these two methods in extracted teeth. A total of 100 first permanent molars and 100 second primary molars were used and teeth and sites with questionable or borderline caries were selected for examination. The condition of the tooth on section was used to validate. In these samples sensitivity of radiographic diagnosis was greater than that of visual diagnosis. Both methods showed good specificity. When radiographs were used together with visual examination the status of 82% of first permanent molars and 91% of second primary molars were correctly classified.
事实证明，早期咬合面龋的诊断比平滑面或邻面龋的诊断更为困难。随着时间的推移，这种类型的病变在整个龋齿中所占比例越来越大，因此其准确诊断变得越发重要。最常用的诊断方法是视觉检查和咬合翼片X线摄影，但这两种方法对咬合面龋的诊断价值都受到了质疑。本研究的目的是调查在拔除的牙齿中使用这两种方法进行诊断的有效性。总共使用了100颗第一恒磨牙和100颗第二乳磨牙，并选择有可疑或临界龋的牙齿及部位进行检查。用牙齿剖面的情况进行验证。在这些样本中，X线摄影诊断的敏感性高于视觉诊断。两种方法都显示出良好的特异性。当X线片与视觉检查一起使用时，82%的第一恒磨牙和91%的第二乳磨牙的状况被正确分类。
