Materials and Methods: A multi-shade (Filtek Ultimate) and four one-shade (Omnichroma, Charisma Diamond One, Essentia Universal, Vittra Unique) composite resins were used. A total of 160 samples, 32 of each composite were prepared and the initial color parameters of the composite samples were measured with a spectrophotometer and the composite samples in each group were divided into four groups (n=8). Then, the samples were kept in coffee and second color measurements were made. After the samples were kept in four whitening mouthwashes (Colgate Optic White, Listerin Advanced White, Pasta del Capitano Whitening, SPLAT® Professional Bio-Active), third color measurements were made and color changes were calculated with the CIEDE2000 formula. Statistical analyzes were performed using one-way ANOVA and post-hoc Tukey’s test. Results: The color changes observed in the stained composite resins after immersion in mouthwash were statistically significant, varying by mouthwashes and composites (p≤0.05). Average color change values (ΔE00) were between 0.85 and 4.87. While the highest color change was observed in the Charisma Diamond One group using Pasta del Capitano Whitening (ΔE00=4.87), the lowest color change in all groups was observed in the use of SPLAT® Professional Bio-Active. Conclusion: One-shade composites showed more color change than the multi-shade composite, with variations depending on the mouthwash used. Almost all groups, whitening mouthwashes caused a color change above the perceptibility threshold level.}, number={1}, publisher={Necmettin Erbakan Üniversitesi}
