Aim: To evaluate surface roughness of tooth enamel when submitted to erosive challenge from beverages after 07, 14 and 21 days as well as the influence of fluoride toothpaste on enamel surface roughness after the erosive challenges. Methods: Forty enamel blocks were made and divided into 8 groups according to treatment (n=5): G1 - apple juice Ades ®; G1F - apple juice Ades ® + fluoride toothpaste; G2 - honey; G2F - honey + fluoride toothpaste; G3 - fermented milk Chamyto ®; G3F - fermented milk Chamyto ® + fluoride toothpaste ; G4 - control; G4F - control + fluoride toothpaste. After initial analysis of surface roughness, specimens were submitted to erosive challenges. In the groups submitted to fluoride treatment, specimens were immersed in diluted fluoride toothpaste. Analysis of surface roughness was conducted after 7, 14 and 21 days. The values of average enamel roughness (Ra) in the experimental groups were submitted to Friedman and Wilcoxon test considering the significance level of 5%. Results: The G2 and G2F group presented statistically higher roughness values (p=0,01) compared to baseline, after 21 and 7 days, respectively. For G3 (p=0,006) and G3F group (p=0,01), roughness values were statistically higher after 7 days compared baseline. Conclusion: Enamel roughness values increased after erosive challenge with honey and fermented milk. Application of fluoride toothpaste did not promote lower roughness values.
