Objective In this in vitro study, the color change of artificial caries lesions in enamel was evaluated after resin infiltration (Icon ® , DMG, Hamburg, Germany) or remineralization. Methods Bovine enamel specimens ( n = 72) were randomly divided into four groups: G 1 – exposure to demineralizing solution (32 h) and resin infiltration; G 2 – immersion in demineralizing solution and remineralization cycles (8 days); G 3 – demineralizing solution (negative control); G 4 – healthy/non‐treated enamel (positive control). The groups were subdivided and immersed in: A (saliva), B (coffee), and C (wine). The baseline color was evaluated by spectrophotometer and repeated after 4 and 8 weeks, and after polishing, at the end of 8 weeks. The variation in color (∆E) and lightness (∆L) was analyzed by anova (two‐way) and T ukey tests, and F riedman and K ruskal– W allis tests, respectively. Results All specimens underwent color and lightness change, irrespective of immersion medium. In coffee, G 2 presented the lowest mean ∆E ( P < 0.05), compared with the other groups. In saliva, G 3 presented the highest mean ∆E, and G 2 and G 4 lower ∆E means. Conclusion Lesions infiltrated with Icon ® underwent greater color change when compared with remineralized lesions, which may represent an esthetic disadvantage for the first‐mentioned treatment.
