Objective: To identify a potential summative summary measure that reflects a patient's overall caries level in children examined with the International Caries Detection and Assessment System (ICDAS). Subjects and Methods: Participants were 1- to 15-year-old children from Kuwait, Brazil, and Spain. Children's teeth were examined using the ICDAS. Multiple measures of central tendency and dentition-specific indices were considered as potential summative measures. The relationship between the summative measures and number of caries lesions was evaluated considering degrees of caries severity using Spearman's correlation analysis. The results were generated using the Kuwaiti sample and were cross-validated using the Brazilian and Spanish samples. Results: A total of 2,808 children participated in the present study. Total ICDAS score and mean ICDAS score showed a strong correlation with the number of caries lesions at different caries severity levels in primary, mixed, and permanent dentitions. The total ICDAS score of 51 buccal (B), 61B, 54 occlusal (O), 55O, 64O, 65O, 74O, 75O, 84O, and 85O surfaces in primary dentition and the total ICDAS score of 14O, 16 lingual (L), 16O, 24O, 26L, 26O, 36B, 36O, 37O, 46O, 46B, and 47O surfaces in permanent dentition or mixed dentition (if present) showed strong correlations with the number of caries lesions at different caries severity levels. Conclusions: Total ICDAS and mean ICDAS scores were the best summary measures of overall caries level at different dental stages. Total ICDAS scores of selectively examined 10 surfaces in primary dentition and 12 surfaces in permanent dentition can give an excellent summary measure for a patient's overall caries level with high diagnostic accuracy.
