This in vitro study evaluated the color stability, gloss, and surface roughness (Ra) of four indirect composites. Enamel and dentin shades of Radica, Sculpture Plus, Belleglass-NG, and Gradia Indirect were evaluated for color stability. Specimens were stored in a staining solution (coffee) and assessed every 3 days for a period of 21 days, after which color difference (ΔE*) was calculated. Only enamel shades were used for measuring gloss and surface roughness at 0, 5000, 10,000, and 20,000 cycles of simulated toothbrushing. The results were statistically analyzed using repeated measures analysis of variance (ANOVA) and Tukey's test. Statistically significant changes in ΔE* during the 21-day period were observed in all indirect composites for enamel and dentin shades, and ΔE* was greater than the clinically acceptable value of 3.3. Belleglass-NG showed the least change in ΔE*, while Sculpture Plus had large changes in ΔE*. In all groups, gloss was 75% lower than baseline values after 10,000 cycles of toothbrushing. After 20,000 cycles, surface roughness was highest in Radica and lowest in Belleglass-NG. Belleglass-NG had higher color stability and gloss retention, and lower surface roughness, as compared with the other composite systems.
