To compare color change magnitude of an infiltrative resin and a flowable composite resin after immersion in commonly consumed beverages.
Disks (1 × 9 mm) of a flowable composite (Filtek Supreme Ultra Flowable) and a resin-infiltrative product (Icon) were made. Specimens were dark-stored in tap water (24 hours). Baseline color parameters (CIE Lab*) were obtained using a colorimeter (Easyshade V4, VITA). Specimens were immersed (dark stored, 37°C, 1 week) in commercial beverages: Kool-Aid, coffee, Coca-Cola, and tap water (control). ΔE between final and baseline conditions for each material/beverage combination was determined (N = 10/group). Initial analysis of variance indicated significant impact of major factors/interactions on ΔE . Subsequently, t-tests between ΔE values of restorative materials within each beverage was performed: alpha 0.05.
Kool-Aid produced the greatest color change for flowable composite, with a ΔE significantly greater than the infiltrative product. No significant ΔE differences were noted between products immersed in coffee, however color parameters causing these differences were not similar. Water or Coca-Cola immersion showed lowest ΔE values for both materials, considered visually imperceptible: ΔE values <0.8.
Color change potential of infiltrative resin or resin composite was highly dependent on beverage type, with no general trends observed in which material was affected more.
Staining potential of an infiltrative restorative resin differs from that of a filled, flowable composite material on a beverage-by-beverage basis. The potential for color change seems not related to the presence or absence of fillers in the restorative material.
比较浸润树脂和流动复合树脂在浸泡于常见饮料后的变色程度。
制作流动复合树脂（Filtek Supreme Ultra Flowable）和树脂渗透型产品（Icon）的圆盘（1×9mm）。将样本在自来水中暗存（24 小时）。使用比色计（Easyshade V4，VITA）获取样本的基础色参数（CIE Lab*）。将样本浸泡于商业饮料中（暗存，37°C，1 周）：Kool-Aid、咖啡、可口可乐和自来水（对照）。确定每种材料/饮料组合的最终和基础条件之间的 ΔE（每组 N=10）。初步方差分析表明，主要因素/相互作用对 ΔE 有显著影响。随后，对每种饮料中修复材料的 ΔE 值进行 t 检验：α0.05。
Kool-Aid 对流动复合树脂的颜色变化最大，ΔE 明显大于渗透型产品。然而，浸泡在咖啡中的两种产品之间未观察到显著的 ΔE 差异，但导致这些差异的颜色参数并不相似。水或可口可乐浸泡对两种材料均显示出最低的 ΔE 值，被认为是肉眼不可见的：ΔE 值<0.8。
渗透树脂或复合树脂的变色潜力高度依赖于饮料类型，未观察到哪种材料受影响更大的一般趋势。
渗透修复树脂的染色潜力与填充型流动复合材料在饮料基础上存在差异。颜色变化的潜力似乎与修复材料中是否存在填料无关。
