Abstract
This study aimed to evaluate the color change and surface roughness of reinforced composite (BRILIANT CRIOS) after immersion in artificial saliva then acidic beverage (Pepsi). Samples from reinforced composite (BRILIANT CRIOS) were evaluated for colour change and surface roughness under immersion inartificial saliva and acidic beverage (Pepsi). A total 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. showed that the color change of Brilliant Crios samples immersed in Pepsi ΔE2 was significantly higher than artificial saliva ΔE1 but the highest value of surface roughness was measured in Pepsi samples, followed by baseline samples, while the lowest value was found in artificial saliva samples. reinforced composite (BRILIANT CRIOS) samples showed color change and surface roughness beyond the clinically acceptable level after immersion in acidic beverage (Pepsi). Reinforced composite, Briliant Crios, artificial saliva, acidic beverage, color change, surface roughness.
