Resumo(s)
The purpose of this in vitro study is to evaluate the efficacy of a commercially available tooth mousse in the remineralization of human enamel in cases of Molar-incisor-hypomineralization (MIH). Treatment protocol with GC Tooth Mousse containing Casein phosphopeptide amorphous calcium phosphate (CPP-ACP) was applied to 12 teeth (4 healthy, 4 hypomineralized with white opacities and 4 hypomineralized with yellow opacities) and the samples were evaluated with polarized Raman microscopy. The depolarization ratio of the symmetric stretching band of phosphate band was compared in each sample before and after treatment with the tooth mousse. The mean depolarization ratio values decreased in all three groups, after the treatment protocol, with significant differences (p < 0.05) for the two hypomineralized teeth’ groups. These results allowed us to conclude that there was an improvement in mineral density and organization of the hypomineralized enamel after treatment with CPP-ACP tooth mousse.
