Aim: The study aimed to evaluate the effect of food simulating liquids with or without simulated tooth brushing on surface roughness of different resin composite materials. Materials and Methods: Three resin composite materials (Palfique LX5, Neo Spectra ST and Brilliant Ever Glow) were used in the study. A total of 180 specimens were prepared, 60 specimens of each composite material. Each main group was divided into three subgroups (n=20) according to the three food simulating liquids (FSL) used (distilled water, methyl ethyl ketone, and 0.02 M citric acid). The specimens were immersed in each FSL for 15 days. Specimens were further subdivided into 2 groups (no brushing and simulated brushing) (n=10). Simulated tooth brushing was done in an automatic toothbrushing machine. Surface roughness was measured and data were collected, tabulated and statistically analyzed. Results: Surface roughness of the three tested composite resin materials without brushing showed no statistically significant difference at p≤0.05 after storage in both distilled water and citric acid. MEK significantly increased the surface roughness of Brilliant everglow. After simulated tooth brushing; Neospectra recorded the highest surface roughness value in citric acid and distilled water. While, Brilliant everglow recorded the lowest surface roughness in citric acid and distilled water. MEK significantly increased the surface roughness of Neospectra and decreased that of Brilliant everglow. Conclusion: The food simulating solutions and simulated tooth brushing altered the surface roughness of tested resin composites and these alterations are material dependent. Repolishing is recommended once per year for Neospectra and Palfique.
