Color stability of different resin composites after thermocycling with different beverages at real intake temperature.
Objectives: The aim of this study was to evaluate the color stability of eight different conventional and bulk fill resin composites after inmersion in thermocycling with different beverages at real intake temperature compared to control temperature.
Methods: Eight different composites were compared: IPS Empress Direct, Filtek Z350, Filtek Bulk Fill, Beautifill II, Clearfil AP-X, Spectra Smart, Forma, Tetric N-Ceram Bulk Fill. For each composite, four different beverages (black tea, coke, wine and water) were evaluated at two different temperatures: control (ambient temperature) or thermocycling (real intake temperature of each beverage). Color differences were evaluated before and after cyclings (delta E) with a spectrophotometer (Vita Easyshade V). Data were evaluated with three-way ANOVA and post-hoc Tukey tests.
Results: Thermocycling promoted an effect on color stability mostly on bulk fill composites than resin composites p<0.05). Different composites behaved differently when exposed to different beverages (p<0.05).
Conclusions: Diffferent composites show different color stability when immersed to different beverages. Temperature of different drinks do affect the color stability of the conventional and bulk fill resin composites, making an impact in terms of esthetics, clinical acceptance, and thus long term success of dental restorations.
