Background: Consumption of certain beverages may affect the esthetic and physical properties of the resin composite, thereby undermining the quality of restorations.

Aim: To analyze the effect of four beverages (tea, Coca-Cola, haldi and lemonade) on color stability of two different types of resin composites in vitro.

Materials and Methods: A nano hybrid composite Filtek Z 350 and a microhybrid composite Spectrum 3D was used for veneer preparation. Each material was randomly divided into four equal subgroups of 10 samples each according to the beverages used (tea, Coca-Cola, haldi and lemonade). The samples were immersed in each beverage for 10 minutes each day. Colour change was observed by spectrophotometer.

Statistical analysis used: One way ANOVA and posthoc LSD tests were used to find the difference in color change in the two resin composites when immersed in different beverages.

Results: Spectrum 3D resin composites showed less colour change as compared to Filtek Z 350 in different beverages. When discoloration in different beverages was considered, maximum discoloration took place in Haldi followed by Lemonade, Coca-Cola and Tea respectively.

Conclusion: The effect of interaction of different resin composites and various beverages depend on a multitude of factors. The color match of esthetic restorations in the oral cavity is affected by dietary habits.
