To evaluate the effect of staining beverages on the color-changing of resin-infiltrated artificial white spot lesions (WSLs).
Thirty-five artificial WSLs were created by pH cycling on flat bovine teeth specimens. The WSLs were treated with resin infiltration and were divided into five groups based on staining beverages: artificial saliva, coffee, wine, green tea, and Coca-Cola. These specimens were subjected to a 28-day exposure to the respective beverages. Color stability was assessed using a spectrophotometer at different time points: baseline, after 7, 14, 21, and 28 days of exposure, and repolishing. The color difference (∆E) between each time point and the baseline was calculated. Statistical analysis was performed using two-way measures ANOVA with a significance level of p = 0.05.
All resin-infiltrated specimens exposed to staining beverages for 7 days exhibited more significant color changes than those exposed to artificial saliva. The color change patterns varied based on the type of beverage. The color alterations intensified with extended immersion in the wine and Coca-Cola groups, while there were no significant differences in the color of specimens after 28 days of immersion in the coffee and green tea groups. However, after cleaning with pumice powder, all specimens showed significantly reduced color changes compared to those observed after 28 days of immersion, except those immersed in coffee.
Exposure of resin-infiltrated bovine tooth specimens to staining beverages resulted in a significant color alteration as the immersion time increased. However, the staining effect could be minimized by cleaning with pumice powder, except for the coffee group.
After resin infiltration treatment, patients should be advised to minimize the consumption of colored beverages to prevent staining that could impact esthetic appearance.
评估染色饮料对树脂渗透型人工白色斑点病变（WSL）变色的影响。
通过在平面牛牙标本上进行 pH 循环，创建了 35 个人工 WSL。用树脂渗透处理 WSL，并根据染色饮料将其分为五组：人工唾液、咖啡、酒、绿茶和可口可乐。这些标本分别用相应的饮料暴露 28 天。在不同的时间点（基线、暴露后 7、14、21 和 28 天以及重新抛光后）使用分光光度计评估颜色稳定性。计算每个时间点与基线之间的颜色差异（∆E）。使用具有显著水平 p = 0.05 的双向测量 ANOVA 进行统计分析。
所有暴露于染色饮料 7 天的树脂渗透标本的颜色变化都比暴露于人工唾液的标本更显著。根据饮料的类型，颜色变化模式也不同。在酒和可口可乐组中，颜色变化随着浸泡时间的延长而加剧，而在咖啡和绿茶组中，浸泡 28 天后标本的颜色没有明显差异。然而，用浮石粉清洗后，所有标本的颜色变化都明显低于浸泡 28 天后的观察值，除了浸泡在咖啡中的标本。
树脂渗透牛牙标本暴露于染色饮料中会导致颜色显著改变，随着浸泡时间的延长而加剧。然而，用浮石粉清洗可以将染色效果最小化，除了咖啡组。
树脂渗透治疗后，应建议患者尽量减少有色饮料的摄入，以防止影响美观的染色。
