Introduction: Shade stability is one of the criteria for success of an aesthetic restoration. The current study assessed the effect of two beverages on the color stability of two nano-composites. Methods: Thirty disk shaped samples (8 x 2 mm) of Filtek Z 350 XT and Ceram X Duo were fabricated in a customized metal mold and immersed in beverages (tea and cola) and distilled water for one week. Baseline and post immersion color measurements were recorded using reflectance spectrophotometer. The data was assessed using SPSS 20 software. Data among the groups was compared by one-way ANOVA and multiple comparisons of mean values by Tukey HSD test (<0.05).
