Material and Methods: Three different resin-based CAD/CAM blocks (Cerasmart, Coltene Brilliant Crios and SHOFU Block HC) were used in this study. A total of 300 CAD/CAM specimens, each with a thickness of 2 mm, were prepared and divided into five groups according to the different mouthrinses. Initial color measurements were performed on a white background using a VITA Easyshade V spectrophotometer (VITA Zahnfabrik, Bad Säckingen, Germany). The specimens were then immersed in four different mouthrinses (Listerine Cool Mint, Sensodyne Promine, Oral B Complete and Colgate Optic White) and artificial saliva for the control group for 24 hours. After immersion, the color measurement was repeated. The obtained data were analyzed using the IBM SPSS Statistic 25.0 software. Normality was assessed using the Kolmogorov-Smirnov and Shapiro Wilk tests. To compare the groups, the one-way ANOVA test was applied to normally distributed data, while the Kruskal-Wallis test was used for non-normally distributed data. Results: Shofu blocks exposed to Listerine Cool Mint were the only group that caused discoloration above the acceptability threshold (ΔE00≤1.8). The highest values above the perceptibility threshold (ΔE00≤0.8) were observed in Shofu blocks. Color changes below the perceptible threshold were observed only in Cerasmart blocks after immersion in Sensodyne Promine mouthrinse (ΔE00=0.6) and artificial saliva (ΔE00=0.67). Conclusions: All CAD/CAM blocks showed some degree of discoloration after exposure to mouthrinses; however, the extent of discoloration varied depending on the material composition.}, number={1}, organization={Bu araştırma, Kocaeli Sağlık ve Teknoloji Üniversitesi Bilimsel Araştırma Projeleri Koordinatörleri tarafından gerçekleştirilmiştir. 2023/22 numaralı proje tarafından desteklenmiştir.}
