The bold values are significant at p<0.05.
Independent-samples Kruskal–Wallis test.
CF, caries-free group (no clinical evidence of caries, ie, ICDAS score = 0 on all teeth); CL, children with cavitated carious lesion or lesions with or without simultaneous noncavitated carious lesions (ie, ICDAS score = 3-6 on at least 1 tooth with or without ICDAS score = 2 on any other tooth/teeth); NC, children with only noncavitated carious lesion or lesions in their oral cavity (ie, ICDAS score = 2 on at least 1 tooth); ICDAS, International Caries Detection and Assessment System; VPI, Visible Plaque Index; WSL, white spot lesion.
