dc.description.abstractThe stainability of ceramic materials is a critical factor in the long-term esthetic success of computer-aided design/computer-aided manufacturing (CAD/CAM) restorations. This study aimed to evaluate the color stainability of CAD/CAM ceramic blocks with different microstructures after immersion in a coffee solution for varying durations. Three types of CAD/CAM blocks—Vita Mark II (MG), Vita Suprinity ([SG] and [SP]), and Vita Enamic (EP)—were used. Finishing and polishing were performed according to the manufacturers’ instructions. CIE L*, a*, and b* values were measured at baseline (T?), and after 1 (T?), 12 (T??), and 30 (T??) days of immersion in coffee using a spectrophotometer. Color differences (?E??), ?L', ?C', and ?H' were calculated using the CIEDE2000 formula. One-way ANOVA was used to compare these values across materials. Multiple linear regression analysis was conducted to assess the influence of ?L', ?C', and ?H' on ?E?? (p<0.05). Statistically significant differences in ?E??, ?L', ?C', and ?H' values were observed at all time intervals (p=.000), except for ?H' between T?-T?? (p=.199). ?L' was the primary influencing factor for MG, SG, and SP materials, while ?H' had the greatest effect on EP over the T?–T?? interval. Within the limitations of this study, the chemical composition of the material influenced ?E??, ?L', ?C', and ?H' values. SG showed the lowest and clinically acceptable level of staining, while EP exhibited a moderate but clinically unacceptable degree of discoloration.
