比较柯达Ektaspeed膜与柯达Ultraspeed膜对干燥人下颌骨牙周小骨病变的检测效果。16名牙医担任观察员，他们比较病变发生前后的x光片，并使用诊断置信度量表记录病变的存在或不存在。为每个观察者和类型的胶片绘制roc曲线，曲线下的面积被用作诊断准确性的衡量标准。两种类型的薄膜在观察者区分有和没有病变的牙周骨区域的能力方面没有统计学上的显著差异。
Kodak Ektaspeed films were compared with Kodak Ultraspeed films for the detection of small periodontal bone lesions prepared in dry human mandibular jaws. Sixteen dentists served as observers who compared radiographs before and after lesions were made and registered the presence or absence of lesions using a diagnostic confidence scale. ROC-curves were drawn for each observer and type of film and the area under the curves was used as a measure of diagnostic accuracy. No statistically significant difference could be demonstrated between the two types of film concerning the ability of the observers to discriminate between periodontal bone areas with and without lesions.
