Effects of thermal cycles and immersion in different beverages on color, translucency and hardness of different composite resins

The aim of this study is to evaluate the color stability, translucency and hardness eight different composite resins, after thermal cycling immersion in beverages. Six light-cured dimethacrylate-based (Clearfil Majesty Esthetic, Clearfil Posterior, Grandio, Grandio Flow, Arabesk Top, Valux Plus), an ormocer (Admira) a silorane-based (Filtek Silorane) were tested study. Fifteen samples (8x2 mm) from each prepared. All subjected [(5.0 ± 0.5)~(55.0 1.0) °C, 1000 cycles]. After cycling, fifteen specimens group divided into three subgroups (n = 5): distilled water (control), coffee, red wine at 37°C for 30 days. With spectrophotometer, △E Translucency Parameter (TP) calculated against white black backgrounds. Color, all remeasured baseline, cycles data analyzed using repeated measured analysis variance Bonferroni multiple-comparison test (P3.3). effect on transluceny was not statistically significant (P>0.05). TP values generally decreased especially (P
