In a continuous process such as caries, it is important to possess criteria or instruments that allow the lesions to be diagnosed at early stages so that preventive or interceptive treatments can be applied before cavitation takes place. The present study seeks to assess the diagnostic efficacy of the International Caries Detection and Assessment System (ICDAS II) criteria and the DIAGNOdent laser fluorescence (LF) pen in occlusal caries lesions, using histological sections as the gold standard. Sixty-four permanent teeth were examined by two researchers who previously performed and calibrated both the ICDAS II criteria and the use of DIAGNOdent pen. The teeth were then cut into sections and observed under an optical microscope. The sensitivity values were 0.82 (ICDAS II) and 0.85 (LF). The specificity values were 1.00 (ICDAS II) and 0.53 (LF). The intraexaminer reproducibility was 0.892 for ICDAS II and 0.912 for the DIAGNOdent, so it was high for both diagnostic methods. However, the DIAGNOdent pen showed greater sensitivity and the ICDAS criteria more specificity. It was concluded that both methods are efficacious individually but combining the two is recommended to improve the diagnosis.
在诸如龋齿这样的连续病变过程中，拥有能够在早期阶段诊断病变的标准或工具非常重要，以便在龋洞形成之前进行预防性或阻断性治疗。本研究旨在以组织学切片作为金标准，评估国际龋病检测与评估系统（ICDAS II）标准和DIAGNOdent激光荧光（LF）笔对咬合面龋损的诊断效能。由两名研究人员对64颗恒牙进行检查，这两名研究人员之前已对ICDAS II标准和DIAGNOdent笔的使用进行了操作和校准。然后将牙齿切成切片并在光学显微镜下观察。敏感度值分别为0.82（ICDAS II）和0.85（LF）。特异度值分别为1.00（ICDAS II）和0.53（LF）。ICDAS II的检查者内重复性为0.892，DIAGNOdent的为0.912，因此两种诊断方法的重复性都很高。然而，DIAGNOdent笔显示出更高的敏感度，而ICDAS标准则具有更高的特异度。得出的结论是，两种方法各自都有效，但建议将两者结合以改善诊断。
