| Popis: | Objective: This study aimed to investigate the effect of various beverages on the color stability of nanohybrid and bulk-fill resin composites.Methods: In this experimental study, 36 disk-shaped composite samples (6 mm diameter, 4 mm thickness) were prepared from three types of composite resins (n=12): a nanohybrid composite (Filtek Z550), a bulk-fill composite (Tetric EvoCeram Bulk Fill) and a flowable bulk-fill composite (Filtek Bulk Fill Flowable). The samples from each composite were then divided into four subgroups based on the applied staining solution (n=3) and immersed for 120 hours in either distilled water, chocolate milk, cola, or orange juice. Color measurements were conducted at baseline and after immersion in staining solutions by a VITA Easyshade Compact according to the CIELAB color system. Color changes (∆E) were analyzed by a two-way ANOVA at the significance level of P3.3) after immersion in various beverages. The greatest color changes were usually found in Filtek Bulk Fill Flowable composite. Both bulk fill composites showed significantly greater color changes than the nanohybrid composite after immersion in distilled water and chocolate milk (P |
