Abstract:
This study aimed to investigate the effects of four alcoholic beverages on enamel erosion. Fifty enamel specimens were randomly allocated into the following five groups (n=10): group 1, water as negative control; group 2, red wine; group 3, white wine; group 4, distilled spirit; and group 5, beer. The specimens were immersed in the respective solution for a 16 h demineralization, followed by an 8 h remineralization in artificial saliva. Cyclic de- and re-mineralization were performed for 8 days. Surface roughness, microhardness and morphology of the enamel specimens were studied after the cycling. The results were analyzed by One-way ANOVA and Dunnett's post-hoc test (p<0.05). All investigated beverages showed an erosive effect on enamel. White wine had the highest erosive potential whereas distilled spirit had the least.
