Objective: The purpose of the study is to evaluate the color stability and surface roughness of smart chromatic composite resin and methacrylate composite resins with applying different polishing systems and stored in different solutions. Methods: In the study, 120 disc-shaped specimens were prepared from a smart chromatic composite, a nanofill composite, and a nanohybrid composite. The specimens were separated into 12 groups with a specimen size of 10, and the two different polishing systems were utilized. The initial color values of the specimens were measured with a spectrophotometer and the surface roughness values were measured with a profilometer. Then, the specimens were stored in two different beverage solutions, and color and roughness measurements were repeated. The mean color change values of the specimens were calculated in ΔE, and the surface roughness values were recorded in Ra. Statistical analysis of the data was performed using One-way ANOVA and post hoc Tukey test (P =.05). Results: Statistically significant variations were observed in the mean color change values among the groups, as a consequence of the utilization of various polishing systems and exposure to different solutions (P.05). Although no significant variations were observed in the mean surface roughness values of the specimens due to exposure to different solutions (P >.05), significant distinctions were identified among the groups to which different polishing systems were employed (P <.05). Conclusion: The application of different polishing systems and exposure to various solutions can result in variations in color and surface roughness values for composite resins, owing to their inherent structural characteristics.
