Abstract

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 three beverages (Whiskey, Coca-Cola, and Nimbooz) on color stability and surface roughness of two different types of resin composites at various time intervals in vitro. Materials and Methods: A methacrylate-based nanofilled composite and a silorane-based microhybrid composite were used. Each material was randomly divided into four equal subgroups of 10 samples each according to the beverages used (Whiskey, Coca-Cola, Nimbooz, and Distilled water). The samples were immersed in each beverage for 10 minutes each day for 56 days. Color change and surface roughness measurements were noted at the baseline - the seventh, fourteenth, twenty-eighth, and fifty-sixth day. Statistical Analysis Used: RANOVA and Bonferroni tests were used to find the difference in color change and surface roughness in the two resin composites when immersed in different beverages. The Pearson Correlation test was carried out to test if any correlation existed between color change and surface roughness. Results: Silorane-based resin composites were more stable in different beverages over time. Conclusion: The effect of interaction of different resin composites, various beverages, and time depended on a multitude of factors.
