Abstract Objectives: The present study aims to evaluate the color change and surface roughness of reinforced composite (BRILIANT CRIOS) after immersion in acidic beverage (Pepsi). Methodology: Samples from reinforced composite (BRILIANT CRIOS) were evaluated for colour change and surface roughness under immersion inartificial saliva and acidic beverage (Pepsi). Atotal of 23 samples were prepared 1mm in thickness and (14 × 12 × 18 (mm) in dimensions. The average colour difference (Delta E*) was computed following immersion in artificial saliva and an acidic beverage. Color parameters were measured before and after the immersion using a spectrophotometer analysis. A non-contact profilometer was used to measure the surface roughness.The Shapiro-Wilk test was used for statistical analysis. Data had a parametric distribution, thus we used repeated measures ANOVA and the Bonferroni post hoc test to examine them. The significance level was set at P ≤ 0.05. Results: There was a significant color change in samples immersed in Pepsi (3.62±1.80) was significantly higher than that of samples subjected to artificial saliva. Color change (2.20±0.97) (t=5.77, p<0.001). There was a significant difference between roughness values measured in artificial saliva and Pepsi (f=19.29, p<0.001). The highest value was measured in Pepsi samples (0.2927±0.0021), followed by baseline samples (0.2902±0.0032), while the lowest value was found in artificial saliva samples (0.2897±0.0039). Post hoc pairwise comparisons showed Pepsi samples to have significantly higher values than baseline and artificial saliva (p<0.001). Conclusion: reinforced composite (BRILIANT CRIOS) samples showed color change and surface roughness beyond the clinically acceptable level after immersion in acidic beverage (Pepsi).
