Objective: To compare in vitro the superficial microhardness and roughness of the ceromer before and after being exposed to an energizing drink. Materials and methods: This study was of experimental type in vitro. Twenty cylindrical discs (6 mm high and 4 mm wide) of the SR Adoro® ceromer were divided into two groups to evaluate the surface microhardness and surface roughness. The erosive challenge was performed for 30 minutes / 1 time / 5 days with the Red Bull® drink. The statistical analysis that was used to evaluate the surface microhardness was the Wilcoxon test. However, the Student's T test was used to evaluate the surface roughness. Results: Statistically significant differences were found when evaluating surface microhardness. However, no significant differences were found when evaluating the roughness of the ceromer. The mean and standard deviation of the surface microhardness of the SR Adoro® ceromer before the erosive challenge was 55.45 + 6.42 MPa and after the erosive challenge was 38.24 + 6.09 MPa. The difference of initial and final surface microhardness was 17.21 + 0.33 µm. The mean and standard deviation of the rugosity of the SR Adoro® ceromer before the erosive challenge was 1.66 + 0.30 µm and then was 1.703 + 0.43 µm. The initial and final roughness difference of the SR Adoro® ceromer exposed to the beverage (Red Bull®) was 0.04 + 0.33 µm. Conclusions: There are statistically significant differences when evaluating surface microhardness. However, no statistically significant differences were found when assessing the rugosity of the SR Adoro® ceromer (p<0.05, p = 0.808) when exposed to a Red Bull® energy drink.
