Aim: This study evaluates Vickers microhardness and surface roughness in Biodentine cement (M1) and glass-ionomer cement Fuji IX (M2), both immersed in mouthwash. Materials and Methods: Fifty-four samples were randomly distributed in distilled water (S1), Listerine Cool Mint (S2), and Colgate Plax (S3). Each sample was put in a flask with mouthwash for 2 min, under vibration, twice a day for 21 days. Microhardness and surface roughness were assessed at 48 h (T0), 7 days (T1), 14 days (T2), and 21 days (T3). Results: For roughness: time (T), solution (S) and material (M), TxM, and SxM and for microhardness: M, TxS, TxM, and SxM were statistically significant. T3, M1, M1T3, and M1S1 presented the highest surface roughness. M2, M1T0, M1T1, M1T2, M1S1, and M1S2 presented higher microhardness. Conclusion: Biodentine showed higher surface roughness for T1, T2, and T3 and higher microhardness for T0, T1, and T2 against Fuji IX. Biodentine presented higher microhardness independently of solution.
