Background and Aim: Acidic drinks cause non-microbial dental wear, which causes irreversible changes in the enamel and increase the tooth's susceptibility to decay, as well as increasing the adhesion of plaque and reducing the beauty of the composite. Therefore, in order to compare the effect of some common drinks on surface roughness. Tooth enamel and a type of composite were used in this research. Material and Methods: This research was done experimentally and in vitro. A total of 72 samples including 36 dental group samples (group 1) and 36 composite samples (group 2) were divided. 18 qualified premolar teeth (without mass, cracks and decay) and after washing with distilled water and removing contamination with 0.5% chloramine solution at room temperature Then the roots of the teeth were cut from the CEJ region and enamel blocks (labial and lingual) were prepared from their crowns. After mounting the enamel blocks and washing and drying them, and 36 discs were prepared from microhybrid composite and after curing and polishing the initial roughness of the blocks was measured with a profilometer. Then the samples were randomly divided into three groups (Hype, Delster, Cocacola). The samples were placed in their drink group three times a day for 20 minutes and during 14 days, and then the final Roughness with the same Profilometer was measured. Finally, the data were analyzed with one-way ANOVA followed by Tukey's multiple comparisons, two-way ANOVA and T-test. Results: All drinks in this research increase the roughness of teeth and composites. In the comparison between the effects of the three mentioned drinks on tooth enamel roughness, there is a significant difference. And it was the highest in ―Hype‖ group (P<0.05) It is more in Delster group than Cocacola group, but this difference is not statistically significant (p>0.05). In the composite groups, the hype drink caused the most changes in the composites, which was significant compared to the Cocacola group (p<0.05) and not significant compared to the Delster group (p>0.05). In the comparison between dental groups and composite groups, changes in dental groups are more than composite in all types of drinks and there is a significant difference in Hype (p<0.05). Conclusion: All types of carbonated drinks increased the roughness of teeth and composites, and also acidic drinks have a greater effect on teeth compared to composites. increase the roughness with Hype drink is more than Delster and cocacola.
