Bottom Line: Comparing the kappa values for the whole sample and the independent sites, no effect or only a small effect was found.Comparing the areas under the ROC-curves no effect could be shown.Examining multiple sites on teeth leads to results comparable to when a single independent site is chosen per tooth.

ABSTRACT
Carious lesions can occur at different sites on the occlusal surfaces of teeth and may differ in appearance and severity. This study aimed to evaluate how estimates of reproducibility and accuracy of ICDAS-II were affected when all lesions on occlusal surfaces, or only a representative lesion, were scored. 100 permanent teeth with 1-4 investigation sites on the occlusal surface were examined visually by four examiners. Serial sections of the teeth were assessed for lesion depth. Intra- and interexaminer reproducibility (weighted kappa values), sensitivity, and specificity were calculated for all investigation sites and for a randomly selected site per tooth. Comparing the kappa values for the whole sample and the independent sites, no effect or only a small effect was found. Comparing the areas under the ROC-curves no effect could be shown. Examining multiple sites on teeth leads to results comparable to when a single independent site is chosen per tooth.

Mentions: Figure 2 shows the distribution in the differences between the scores at each investigation site in each surface for each examiner when using ICDAS-II and for the consensus histological scores. For example for examiner 1 in 40.8% of the teeth the ICDAS-II score differed from one site to another by an ICDAS-II score of 1, in 28.6% of teeth the score differed by 2, and so forth. It can be seen from the differences in histological score from one site to another that lesions can be of different severity from one site to another on a single tooth and that this is reflected in the differences recorded in the ICDAS-II scoring.
