目的：建立一种定量测量龋病深度和宽度的方法。材料和方法：选取110颗拔除的患龋恒磨牙，通过ICDAS评分系统进行视觉评分，然后进行近远中切面，得到面侧和舌侧部分。从每个部分拍摄数码照片和X线照片。通过随机化，选择其中一个切片进行进一步检查。拍摄了第一张数码照片。在切片着色之前（H（un-col））和之后（H（col）），在图像上用箭头标记病变的深度和宽度。在X光片（R）上进行相同类型的测量。按相同顺序测量病变的相对牙本质深度和宽度。结果：ICDAS评分的加权检查内和检查间kappa值在0.85和0.90之间变化。36颗随机选择的牙齿的牙本质深度的检查者内kappa值分别为0.75（H（un-col））、0.91（H（col））、0.79（R）;牙本质宽度的检查者内kappa值分别为0.84（H（un-col））、0.96（H（col））、0.84（R）。在H（un-col）、H（col）和R中，ICDAS评分与病灶深度和宽度的测量值之间存在显著相关性（p < 0.000）。H（un-col）和H col之间在病变的相对深度和宽度方面测量到的最低差异为45%（H（un-col）-H（col））和73%（H（col）-R）。结论：利用组织学和X线技术测量龋病的深度和宽度是可行的，并具有较高的重复性。版权所有（C）2011 S.

Aim: To develop a measurement method to quantify the depth and width of occlusal caries lesions. Material and Methods: One hundred and ten extracted permanent molars with occlusal caries lesions were selected, then visually scored by ICDAS scoring system and then sectioned mesiodistally, resulting in a facial and a lingual fraction. Digital photos and radiographs were taken from each section. By randomization, one of the sections was chosen for further examinations. First digital photos were taken. Depth and width of the lesions were marked with arrows on the images both before (H(un-col)) and after coloring (H(col)) the sections. The same types of measurements were done on the radiographs (R). The relative dentinal depth and width of the lesions were measured in the same order. Results: Weighted intra- and interexaminer kappa value for ICDAS scorings varied between 0.85 and 0.90. Intraexaminer kappa for dentinal depth in 36 randomized selected teeth was calculated to 0.75 (H(un-col)), 0.91 (H(col)), 0.79 (R) and for dentinal width to 0.84 (H(un-col)), 0.96 (H(col)), 0.84 (R). Significant correlations were found between ICDAS scorings and the measurements of depth and width of lesions in H(un-col), H(col), and R (p < 0.000). The lowest difference was measured between H(un-col) and H col in both relative depth and width of the lesion with maximum differences up to 45% (H(un-col)-H(col)) and 73% (H(col)-R). Conclusion: It is possible to measure depth and width of occlusal caries lesions by means of histological and radiographic technique with acceptably high reproducibility using this method.
