Popis: Background: The aim of this study is to evaluate the color stability of hybrid ceramics stored in different combinations of different beverages that would be consumed in a daily routine. Methods: The specimens were prepared with resin nano-ceramic (Lava Ultimate, 3M Espe, USA) and hybrid ceramic (Vita Enamic, Vita Zahnfabrik, Germany). The specimens were aged in a thermocycler machine for 10,000 cycles. They were stored in different combinations of beverages (water, tea, coke, coffee, red wine, pomegranate juice, turnip juice) for 12+12 hours-time. The surface roughness measurements were made with a profilometer. The color measurements of the specimens were measured with the spectrophotometer. The color values (L-a-b) of the specimens, and mean surface roughness values (Ra) were recorded at the end of the 1st (D1), 7th (D7), 14th (D14) and 28th (D28) days.Results: When the solution groups are examined; significantly more color changes were observed in the LG4, EG4, LG6 and EG6 groups than in the other groups (pConclusion: More color changes (except for the samples stored in coffee-wine) were observed in the Lava samples than in the Enamic samples in all groups and periods. The combination of coffee-tea and coffee-wine beverages may have accepted most coloring beverages for hybrid ceramics within the limitation of this study.
