This study examined the changes in color and translucency of flowable composites after immersion in different beverages. Thirty composite samples were prepared from four flowable composites (G-aenial Universal Flo, Filtek Ultimate, Esthelite Flow Quick, and Clearfil Majesty ES Flow) and a microhybrid composite (Filtek Z-250) and stored in distilled water at 37°C for 24 h. The samples were randomly divided into seven groups and then immersed in different beverages (Red Bull, coffee, black tea, Pepsi Cola, orange juice, and distilled water) for 7 days. The CIE L*a*b* values of each sample were measured against white and black backgrounds using a spectrophotometer before and after immersion. Data were analyzed using two-way analysis of variance and Tukey's post-hoc test (p < 0.05). The color changes were significantly different among the composite materials after immersion in beverages (p < 0.05). Filtek Ultimate and Esthelite Flow Quick exhibited less discoloration than did G-aenial Universal Flo and Clearfil Majesty ES Flow. No significant difference was found between Filtek Z-250 and either Filtek Ultimate or Esthelite Flow Quick (p > 0.05). Among the beverages, black tea and coffee caused the highest discoloration of all the materials. Immersion in coffee and black tea resulted in the highest negative changes in the translucency of the materials. The degree of discoloration for the composite resins depended on the material used and drinking beverage. SCANNING 38:701-709, 2016. © 2016 Wiley Periodicals, Inc.

不同饮料对可流动复合材料颜色和半透明性的影响

本研究检查了可流动复合材料在浸入不同饮料后的颜色和半透明度变化。由四种可流动复合材料（G-aenial Universal Flo、Filtek Ultimate、Esthelite Flow Quick 和 Clearfil Majesty ES Flow）和一种微杂交复合材料 (Filtek Z-250) 制备 30 个复合样品，并在 37°C 的蒸馏水中储存 24 H。将样品随机分为七组，然后在不同的饮料（红牛、咖啡、红茶、百事可乐、橙汁和蒸馏水）中浸泡 7 天。每个样品的 CIE L*a*b* 值在浸入前后使用分光光度计在白色和黑色背景下进行测量。使用方差的双向分析和 Tukey 事后检验 (p < 0.05) 分析数据。浸泡在饮料中后，复合材料的颜色变化有显着差异（p < 0.05）。与 G-aenial Universal Flo 和 Clearfil Majesty ES Flow 相比，Filtek Ultimate 和 Esthelite Flow Quick 的变色更少。Filtek Z-250 与 Filtek Ultimate 或 Esthelite Flow Quick 之间没有发现显着差异（p > 0.05）。在饮料中，红茶和咖啡导致所有材料的变色程度最高。浸泡在咖啡和红茶中会导致材料半透明度的最大负面变化。复合树脂的变色程度取决于使用的材料和饮用的饮料。扫描 38:701-709, 2016. © 2016 Wiley Periodicals, Inc. 与 G-aenial Universal Flo 和 Clearfil Majesty ES Flow 相比，Filtek Ultimate 和 Esthelite Flow Quick 的变色更少。Filtek Z-250 与 Filtek Ultimate 或 Esthelite Flow Quick 之间没有发现显着差异（p > 0.05）。在饮料中，红茶和咖啡导致所有材料的变色程度最高。浸泡在咖啡和红茶中会导致材料半透明度的最大负面变化。复合树脂的变色程度取决于使用的材料和饮用的饮料。扫描 38:701-709, 2016. © 2016 Wiley Periodicals, Inc. 与 G-aenial Universal Flo 和 Clearfil Majesty ES Flow 相比，Filtek Ultimate 和 Esthelite Flow Quick 的变色更少。Filtek Z-250 与 Filtek Ultimate 或 Esthelite Flow Quick 之间没有发现显着差异（p > 0.05）。在饮料中，红茶和咖啡导致所有材料的变色程度最高。浸泡在咖啡和红茶中会导致材料半透明度的最大负面变化。复合树脂的变色程度取决于使用的材料和饮用的饮料。扫描 38:701-709, 2016. © 2016 Wiley Periodicals, Inc. 在所有材料中，红茶和咖啡的变色程度最高。浸泡在咖啡和红茶中会导致材料半透明度的最大负面变化。复合树脂的变色程度取决于使用的材料和饮用的饮料。扫描 38:701-709, 2016. © 2016 Wiley Periodicals, Inc. 在所有材料中，红茶和咖啡的变色程度最高。浸泡在咖啡和红茶中会导致材料半透明度的最大负面变化。复合树脂的变色程度取决于使用的材料和饮用的饮料。扫描 38:701-709, 2016. © 2016 Wiley Periodicals, Inc.
