Results are based on two-sided tests with a significance level of 0.05, using the Bonferroni collection; for each significant pair, the key of the category (A, B, or C); **the frequency is significantly higher than the number under the category that appears next to it; *p-value significant at 0.05; ¥the total number of APF surfaces is less than the total included surfaces (n = 2E) because the clinical base line of 13 surfaces was not missing; APF, acidulated phosphate fluoride; ICDAS, International Caries Detection and Assessment System
