Data was analyzed using the repeated-measures analysis of variance (ANOVA) and the Bonferroni method. A statistically significant decrease was observed in the surface microhardness of the microhybrid composite specimens after bleaching (p 0.05).The highest ΔE values were observed in the red wine groups for both composite resins. Staining and bleaching may affect surface properties and color, depending on the type, filler and matrix content of the composite resin. Staining and bleaching may affect surface properties and colo
