To evaluate the effect of staining beverages on the color stability, translucency and gloss of two provisional restorative materials.
Sixty discs (8 mm x 2 mm) were manufactured for Duralay and Protemp 4. The discs were randomly divided according to the beverages: tea, coffee, wine, Coca-Cola and "Chicha morada" (n=12). The discs were polished and initial recordings of color and translucency were made with a spectrophotometer, and the gloss was measured with a glossmeter. The discs were immersed for 5 days in each of the beverages at 37◦C, and the color, translucency and gloss were recorded again. The differences between the initial and final records were calculated to obtain the values of ΔE, ΔTP, ΔGU. For the analysis, the two-way MANOVA model was chosen, and the significance level was set at 5%.
A significant interaction was observed between the type of material and the staining beverages on the changes observed in the values of ΔE, ΔTP, ΔGU (<0.05). ΔE values for Duralay and Protemp 4 were affected by coffee (7.48±1.53) and wine (11.02±1.07), respectively. The greatest change in ΔTP for Duralay were generated by tea (-1.79±0.62), and coffee (-5.65±0.66) for Protemp 4. Gloss was affected mainly by coffee for both materials (Duralay = -6.44±1.17 , Protemp 4 = -8.28±1.09).
The type of material and the pigment drinks act together to influence changes in color, translucency and gloss. The methacrylate-based resin was more stable than the bis-acrylic resin to changes in color, translucency and gloss. Color, translucency, gloss, staining solutions, interim restorations.
评估染色饮料对两种临时修复材料的颜色稳定性、半透明性和光泽度的影响。
为Duralay和Protemp 4制作了60个圆盘（8毫米×2毫米）。圆盘根据饮料随机分组：茶、咖啡、葡萄酒、可口可乐和“紫玉米糊”（n = 12）。对圆盘进行抛光，用分光光度计对颜色和半透明性进行初始记录，并用光泽计测量光泽度。将圆盘在37℃下分别浸泡在每种饮料中5天，然后再次记录颜色、半透明性和光泽度。计算初始记录和最终记录之间的差异以获得ΔE、ΔTP、ΔGU值。分析时选择双向多变量方差分析模型，显著性水平设定为5%。
在观察到的ΔE、ΔTP、ΔGU值变化方面，材料类型和染色饮料之间存在显著交互作用（<0.05）。Duralay和Protemp 4的ΔE值分别受咖啡（7.48±1.53）和葡萄酒（11.02±1.07）影响。Duralay的ΔTP最大变化由茶（-1.79±0.62）引起，Protemp 4的则由咖啡（-5.65±0.66）引起。两种材料的光泽度主要受咖啡影响（Duralay = -6.44±1.17，Protemp 4 = -8.28±1.09）。
材料类型和色素饮料共同作用影响颜色、半透明性和光泽度的变化。基于甲基丙烯酸酯的树脂在颜色、半透明性和光泽度变化方面比双丙烯酸树脂更稳定。颜色、半透明性、光泽度、染色溶液、临时修复体。
