The aim of this study was to evaluate the color stability of three different adhesive resin cements exposed to differentbeverages.Methods: Total eigthy four specimens (n=7) of each adhesive resin cement (TheraCem, BisCem and Duolink) were prepared. All specimens wereaged by distilled water (control group), coffee, green tea and white tea for 24 days. CIELAB coordinates were acquired by means withspectrophotometer (Vita Easyshade, Vita Zahnfabrik, Bad Sackingen,). Color differences (?E) and whiteness index for dentistry (WID) werecalculated. The values were analyzed by two-way ANOVA and Tukey honestly significant difference test was used to compare group (?=0.05).Results: TheraCem showed highest ?E values and Duolink lowest ?E values after immersion in distilled water, coffee, green tea and white tea. Alltested specimens indicated clinically unacceptable color changes (?E) after 24 days immersion in coffee, green tea and white tea.Conclusion: Ingredients and chemical interactions of adhesive resin cements can alter water permeability of material and so color stabilitysignificantly affected. After 24 days, all beverages caused clinically noticeable color changes for all adhesive resin cement groups.eninfo:eu-repo/semantics/openAccessArticle10.30934/kusbed.63543863238244426302
