Background: An increase in consumption of aerated beverages has presented an increase in the wearing of teeth and an increase in the usage of esthetic restoration materials. This study aimed to evaluate surface microhard¬ness of these materials following surface treatment with beverages in in-vitro condition. Material and Methods: The initial surface microhardness of 5 restorative materials: GC Fuji II LC, GC Fuji IX, Nano Glass ionomer, Resin, and Nanocomposite were recorded. All materials were exposed to selected acidic beverages daily and once weekly in a month. The final surface microhardness was recorded following experimentation. Statistical analysis was performed using the student t-test and ANOVA. Results: Inter-group comparisons were made among groups and statis¬tical significance (p<.05) was noted following treatment with beverages. Conclusion: The surface microhardness, roughness, and solubility values of esthetic restoration materials were found to reduce following repeated beverage exposures.
