Abstract

Although several studies have shown promising results in AmF/NaF/SnCl2 solution to inhibit the progression of erosion lesion, there is not a consensus on its frequency of use. Then, the objective of this in vitro study is to evaluate the effect of AmF/NaF/SnCl2 solution, used once or twice a day, on the inhibition of erosion progression on human enamel. Fifty human enamel fragments will be selected under surface Knoop Microhardness and profilometry. After, these fragments will be randomly divided into 05 treatment groups (n=10): G1 - distilled water (negative control); G2 - NaF solution (positive control) 1x /day; G3 - NaF solution 2x/day; G4 - AmF /NaF/SnCl2 solution 1x/day; G5 - AmF/NaF/SnCl2 solution 2x/day. The samples will be submitted to a 04-days erosive cycling in which specimens will be immersed, twice a day, for 4 minutes, in citric acid solution (0.65%, pH 3.6). At the end of the erosive cycling, surface wear will be evaluated under optical profilometry. Results will be submitted to normality and homogeneity tests and then to specific statistical analysis (±=5%).
