Xeroradiographs and conventional film radiographs (D- and E-speed) were compared in a clinical study with the use of 1 complete-mouth radiographs for (1) the presence of interproximal caries and (2) the determination of the depth of interproximal caries with the use of 200 tooth surfaces. In addition, an analysis of correct classification rates making a comparison of the same techniques was conducted. The results with the use of ROC analysis indicated that when a comparison was made of xeroradiography and D- and E-speed film, all techniques were equally useful. A broad range of observer ROC area values was found, indicating that diagnostic performance varies greatly with observer. The results of the diagnostic decisions made on carious surfaces versus noncarious surfaces indicated that all techniques tested were similar: 90% correct for noncarious surfaces and 77% correct for carious surfaces.
在一项临床研究中，对干板X线片和传统胶片X线片（D速和E速）进行了比较，使用了1套全口牙片，用于（1）邻面龋的存在情况，以及（2）通过200个牙面来确定邻面龋的深度。此外，还对相同技术进行比较的正确分类率进行了分析。使用ROC分析的结果表明，当对干板X线摄影与D速和E速胶片进行比较时，所有技术同样有用。发现观察者的ROC面积值范围很广，表明诊断性能因观察者而异。对龋损表面与非龋损表面做出的诊断决策结果表明，所有测试技术都相似：非龋损表面的正确率为90%，龋损表面的正确率为77%。
