本课题对数字减影摄影在人工复发龋损诊断中的准确性进行了评价。数字减影X线片的使用已被证明显著提高了牙周骨破坏的检测准确性，但该方法在继发性龋病的检测中尚未得到评价。在28颗患牙的近中窝洞预备缘处，先后预备了三种不同大小的缺损体，模拟复发龋齿。采用两种不同X线密度的复合修复材料作为后方修复体，分别拍摄每种修复材料的X线片。将X线片数字化并从参考图像中减去，并由7名观察员对常规X线片和减影图像进行评估。数据采用ROC统计方法进行分析。在复发性龋病的检测中，减影摄影优于传统的摄影，主要是因为减少了假阳性诊断。修复体材料的放射不透明度对常规摄影的准确性有显著影响，而对减影摄影则无显著影响。
The diagnostic accuracy of digital subtraction radiography in detection of artificial recurrent caries lesions was assessed in this project. The use of digital subtraction radiography has been shown to markedly increase the accuracy of the detection of destruction in the periodontal bone, but the method has not been evaluated in secondary caries detection. Defects of three different sizes, simulating recurrent caries, were sequentially prepared in the interproximal cavity preparation margins of 28 teeth. Two composite restorative materials with different radiographic densities were used as posterior restorations, and a radiograph was obtained of each defect size and restorative material. The radiographs were digitized and subtracted from the reference images, and the conventional radiographs and the subtraction images were evaluated by seven observers. The data were analysed with ROC statistics. Subtraction radiography was found to be superior to conventional radiography in recurrent caries detection, mainly by reducing the false-positive diagnoses. The radiopacity of the restorative material had a significant effect on accuracy with conventional but not with subtraction radiography.
