| Background: Casein phosphopeptide-amorphous calcium phosphate derived from the milk protein casein. The aims of this study were to investigate the efficacy of CPP-ACP on the microhardness of the sound and artificially caries-like lesion of outer enamel surface in comparison to sodium fluoride 0.05%, stannous fluoride 0.4%, and de-ionized water. Materials and methods: Sixty five maxillary first premolars, two teeth were used for sound and caries- like lesion enamel ground section preparation, while other teeth were randomly divided into two groups, A and B. Group A was consisted of 42 teeth were randomly assigned to five study groups and one control group. After production of initial caries-like lesion of outer enamel surface, the teeth were treated by the selected agents for four minutes separately (CPP-ACP, CPP-ACP+NaF, CPP-ACP+SnF2, NaF 0.05%, and SnF2 0.4%). While Group B consisted of 21 teeth were randomly divided to three study groups, teeth treated with (CPP-ACP, CPP- ACP+NaF, CPP- ACP+SnF2) before demineralization by pH cycling procedure. Results: In both groups showed that agents of study groups were statistically highly significant in elevation of the microhardness values, CPP-ACP+NaF caused highest change in the microhardness (207.21%) for Group A and (19.22%) for Group B, while the lowest change with SnF2 0.4% (74.32%) for Group A and CPP-ACP (8.2%) for Group B. Conclusions: CPP-ACP agents were effective in remineralization of the outer enamel caries-like lesions and the higher remineralizing potential when applied with fluoridated agents; which was reflected by increase in enamel microhardness values. | ||
