Abstract –  Objectives:  The aim of this in vitro study was to assess the inter‐ and intra‐examiner reproducibility and the accuracy of the International Caries Detection and Assessment System‐II (ICDAS‐II) in detecting occlusal caries.Methods:  One hundred and sixty‐three molars were independently assessed twice by two experienced dentists using the 0‐ to 6‐graded ICDAS‐II. The teeth were histologically prepared and classified using two different histological systems [Ekstrand et al. (1997) Caries Research vol. 31, pp. 224–231; Lussi et al. (1999) Caries Research vol. 33, pp. 261–266] and assessed for caries extension. Sensitivity, specificity, accuracy and area under the ROC curve (Az) were obtained at D2 and D3 thresholds. Unweighted kappa coefficient was used to assess inter‐ and intra‐examiner reproducibility.Results:  For the Ekstrand et al. histological classification the sensitivity was 0.99 and 1.00, specificity 1.00 and 0.69 and accuracy 0.99 and 0.76 at D2 and D3, respectively. For the Lussi et al. histological classification the sensitivity was 0.91 and 0.75, specificity 0.47 and 0.62 and accuracy 0.86 and 0.68 at D2 and D3, respectively. The Az varied from 0.54 to 0.73. The inter‐ and intra‐examiner kappa values were 0.51 and 0.58, respectively.Conclusions:  ICDAS‐II presented good reproducibility and accuracy in detecting occlusal caries, especially caries lesions in the outer half of the enamel.
