Amorphous calcium phosphate, stabilized by casein phosphopeptides, has been found to enhance remineralization of subsurface lesions in permanent teeth. The purpose of the present in vitro study was to evaluate the potential of GC Tooth Mousse to enhance remineralization of initial demineralized enamel sites in primary teeth. Forty-four demineralization sites were created in 22 extracted primary teeth. Samples were randomly assigned to 6 treatment groups (GC Tooth Mousse covering, GC Tooth Mousse covering and demineralization, and control groups). The mineral content of each sample was evaluated using energy dispersive X-ray analysis, performed from the enamel surface of each lesion inwards. The results were analyzed using analysis of variance, with a significance level P<.05. Samples treated with GC Tooth Mousse demonstrated an increase in the calcium-phosphate ratio by approximately 2% near the surface, a minimal increase of 1% at a depth over 60 μm, and no change at a depth from 40 to 60 μm, with no statistically significant differences (P>.05). This study demonstrates a minimal increase in the subsurface calcium-phosphate ratio following GC Tooth Mousse treatment, especially in demineralized enamel tissue.
