OBJECTIVE
The purpose of this study was to assess the in vitro diagnostic ability of visual inspection, film, charge-coupled device (CCD) sensor, photostimulable phosphor (PSP) sensor and cone beam CT in the detection of proximal caries in posterior teeth compared with the histological gold standard.
METHODS
Visual inspection, film, CCD, PSP and cone beam CT images were used to detect proximal caries in the mesial and distal surfaces of 138 teeth (276 surfaces). Visual inspection and evaluation of all intraoral digital and conventional radiographs and cone beam CT images were performed twice by three oral radiologists. Weighted kappa coefficients were calculated to assess intra- and interobserver agreement for each image set, and scores were compared with the histological gold standard using receiver operating characteristic (ROC) analysis to evaluate diagnostic ability.
RESULTS
Intraobserver kappa coefficients calculated for each observer for each method of detecting caries ranged from 0.739 to 0.928. Strong interobserver agreement ranging from 0.631 to 0.811 was found for all detection methods. The highest Az values for all three observers were obtained with the cone beam CT images; however, differences between detection methods were not statistically significant (P > 0.05).
CONCLUSION
Visual inspection, film, CCD, PSP plates and cone beam CT performed similarly in the detection of proximal caries.
目的
本研究旨在评估肉眼观察、胶片、电荷耦合器件（CCD）传感器、光激励磷光体（PSP）传感器和锥形束 CT 检测后牙邻面龋的体外诊断能力，并与组织学金标准进行比较。
方法
使用肉眼观察、胶片、CCD、PSP 和锥形束 CT 图像来检测 138 颗牙齿（276 个面）的近中面和远中面的邻面龋。由三位口腔放射科医生对所有口腔内数字和常规射线照片和锥形束 CT 图像进行两次肉眼观察和评估。使用受试者工作特征（ROC）分析计算每个图像组的观察者内和观察者间加权 κ 系数，以评估诊断能力，并将评分与组织学金标准进行比较。
结果
每位观察者对每种龋病检测方法的观察者内 κ 系数范围为 0.739 至 0.928。所有检测方法的观察者间一致性均较强，范围为 0.631 至 0.811。所有三位观察者的 Az 值最高的均为锥形束 CT 图像；然而，不同检测方法之间的差异无统计学意义（P>0.05）。
结论
肉眼观察、胶片、CCD、PSP 板和锥形束 CT 在检测邻面龋方面表现相似。
