Effect of toothpaste with high fluoride concentration on remineralization of dental substrate with artificial caries

Abstract Introduction fluoride toothpaste is widely used by the population. Objective dentifrices with a high concentration of sodium and presence tricalcium phosphate were developed, providing additional protection to patients vulnerable development caries. This study aimed evaluate influence different on surface internal hardness enamel wear after artificial caries, pH cycling, toothbrushing. Material method blocks (4x4 mm) obtained from 20 bovine teeth. The specimens submitted caries lesion then cycling brushing according dentifrice: Colgate Total 12 Clinpro + Tricalcium Phosphate. Result this period, they analysis superficial profilometry. Scanning Electron Microscopy (SEM) was performed. data evaluated one-way Analysis Variance (ANOVA) mineral recovery profilometry, two-way repeated measures ANOVA hardness. Conclusion analyzing hardness, induction, there significant reduction in that partially recovered regardless dentifrice used. For lower values control side up 90 micrometers test side. As for showed greater when compared Clinpro. It concluded promoted however, resulted tooth enamel.
