To examine the color stability of 3 preheated composite resins immersed in different beverages for 1, 7, and 30 days. Material and Methods: Ninety disc-shaped specimens were prepared, 30 specimens from each of three different restorative materials [GrandioSO (GSO), GrandioSO x-tra (GSX), VisCalor bulk (VCB)], using 8-mm diameter and 4-mm thickness molds. Each group was divided into 3 subgroups (n=10) to be immersed into beverages (red wine, coffee, and distilled water). The color change values [CIEDE2000 (?E00)] were calculated at the end of the 1st, 7th, and 30th days. Generalized linear models and multiple comparison tests with Bonferroni correction at a significance level of p |
