Objective: The adhesive systems which have an important place in modern dentistry can affect the color properties of final resin composite restorations. Therefore, the aim of the present study is to evaluate the influence of current adhesive systems on color, color stability and translucency of resin composites. Methods: Fifty disc-shaped microhybrid resin composite specimens were prepared. Resin composite discs were divided into five groups randomly according to adhesive system including a control group (n=10) (Clearfil Protect Bond, Adper EasyOne, Clearfil QuickBond and Tokuyama BondForce). Color and translucency measurements were performed with a clinical spectrophotometer at baseline, immediately after adhesive system application and after immersion in water for 30 days. For statistical analysis, paired-samples t-test, one-way analysis of variance (ANOVA) and Tukey’s post-hoc comparisons were used (p<0.05). Results: The adhesive application significantly changed the color (E*) of the resin composite discs regardless of the adhesive brand. Storage of the resin composite discs in water for 30 days caused significant color changes in the control group. Significant differences were found in color values of the Adper EasyOne and Clearfil Protect Bond groups after aging. All adhesive groups showed significant color changes in Δb values in comparison with the control group, indicating increasing bluing. The translucency of composite discs applied with BondForce and Adper EasyOne adhesives significantly decreased after aging. Conclusion: The adhesive systems may influence the final color of the restoration, however the adhesive systems tested in the study caused clinically acceptable discoloration at baseline and after aging.
