Frequency distribution of the adhesive remnant index (ARI) scores of the groups^†

N, Sample size; n, number, APF, acidulated phosphate-sodium fluoride; CPP-ACP/wF, casein phosphopeptide-amorphous calcium phosphate with 2% neutral sodium fluoride. ^*Different letters show statistically significant differences. ^†ARI scores: 0, no adhesive remaining on the enamel surface; 1, less than 50% adhesive remaining on tooth; 2, more than 50% adhesive remaining on tooth; 3, all adhesive remaining on tooth surface.
