Objective To investigate the color stability of infiltrant resin together with three other composites exposed to staining solution. Methods Three types of anterior aesthetic composite resins (Filtek Z250, Filtek Z350 XT, and Beautiful Flow Plus F00) and artificial caries with Icon infiltrant resin were used. The samples were randomly divided into two groups (each contained 10 specimens): coffee solution and distilled water immersion for three weeks. Color parameters were determined with the Crystaleye spectrophotometer. Results Artificial caries lesions infiltrated by Icon showed much higher ΔE than those infiltrated by other aesthetic resins (P<0.05). The discoloration of all the experimental resins and the artificial caries infiltrated with Icon increased with time, but the discoloration on the 1 st week was significantly higher than those on the 2 nd and 3 rd weeks. Conclusion Artificial caries infiltrated with Icon was more vulnerable and susceptive to food color than those infiltrated with other aesthetic composite resins.
