The aim of the study was to evaluate the effect of commonly used mouthrinses on the discoloration and whiteness of resin-based restoratives (RBR). Two hundred disc shaped specimens (5mm diameter, 2mm tick) of a micro-hybrid composite (FZ-Filtek Z250, 3M ESPE), a ormocer (AD-Admira, Voco), a giomer (BE-Beautifil II, Shofu) and a compomer (DX-Dyract XP, Dentsply) RBRs were prepared (50 from each). The specimens were stored in distilled water for 24 h, then immersed for another 12 h in five mouthrinses of distilled water, Klorhex, Tantum Verde, Oral-B Complete Lasting Freshness and Listerine Cool Mint. The specimens were subjected to color measurements, using a spectrophotometer (VITA Easyshade V, VITA Zahnfabrik) before and after immersion. Color change (Delta E00) and whiteness index (WID) were calculated and data were analyzed using one-way ANOVA, two-way ANOVA and post-hoc Tukey's test (p < 0.05). BE was the most colored RBRs in all solutions. Delta E-00 values of all RBRs immersed in Tantum Verde were above the acceptability threshold. DX showed the highest negative Delta WID values in all solutions. Delta E-00 and Delta WID showed higher values for all RBRs when immersed in Tantum Verde. FZ and AD are the most successful, BE and DX are the most unsuccessful RBRs in terms of on color stability and whiteness caused by the use of mouthrinse. After all RBRs were immersed in different mouthrinses, they changed in terms of color and whiteness.
