Purpose: The purpose of this study was to evaluate the color stability of different composite resins upon exposure to different drinks which were highly consumed in daily life. Materials and methods: Twenty-five disc-shaped (15×2 mm) cylindrical specimens were prepared for each of 6 different composite resins (Filtek Silorane, Aelite Aesthetic Enamel, Quixfill, Ceram X Mono, Grandio, IntenS). The specimens of each composite resin groups were divided into 5 subgroups (n=5) for storage for 48 hours at 37°C in different types of solutions: water, coffee, tea, cola, and red wine. The color values of all groups were measured before and after exposure to different solutions with a colorimeter (Minolta CR-300). Data were recorded according to the CIE L*a*b* system and then color changes (ΔE*) were calculated. The statistical analysis of the color variation data included a 2way analysis of variance (ANOVA) and the means were compared by Tukey HSD test (α=.05). Results: For the 6 restorative materials tested, the lowest ΔE* values were observed in the water immersed group (p<0.05). The highest color differences were observed in the red wine and coffee immersed groups (p<0.05). When comparing the restorative materials, Aelite Aesthetic Enamel and Filtek Silorane demonstrated significantly showed less color change than the other composite groups (p<0.05). Conclusions: Discoloration of composite resins is based on the composition of the composite resins as well as the type of the drinks. Silorane-based composite resins are resistant to external discoloration.
