OBJECTIVE
To investigate the color stability of infiltrant resin together with three other composites exposed to staining solution.
METHODS
Three types of anterior aesthetic composite resins (Filtek Z250, Filtek Z350 XT, and Beautiful Flow Plus F00) and artificial caries with Icon infiltrant resin were used. The samples were randomly divided into two groups (each contained 10 specimens): coffee solution and distilled water immersion for three weeks. Color parameters were deter-mined with the Crystaleye spectrophotometer.
RESULTS
Artificial caries lesions infiltrated by Icon showed much higher ΔE than those infiltrated by other aesthetic resins (P<0.05). The discoloration of all the experimental resins and the artificial caries infil-trated with Icon increased with time, but the discoloration on the 1st week was significantly higher than those on the 2nd and 3rd weeks.
CONCLUSIONS
Artificial caries infiltrated with Icon was more vulnerable and susceptive to food color than those infiltrated with other aesthetic composite resins.
目的
研究渗透树脂与其他三种复合材料在接触染色溶液后的颜色稳定性。
方法
使用三种类型的前牙美学复合树脂（Filtek Z250、Filtek Z350 XT和Beautiful Flow Plus F00）以及用Icon渗透树脂制作的人工龋。将样本随机分为两组（每组包含10个标本）：分别置于咖啡溶液和蒸馏水中浸泡三周。用Crystaleye分光光度计测定颜色参数。
结果
Icon渗透的人工龋损显示出比其他美学树脂渗透的人工龋损更高的ΔE值（P<0.05）。所有实验树脂以及用Icon渗透的人工龋的变色随时间增加，但第1周的变色明显高于第2周和第3周。
结论
与其他美学复合树脂渗透的人工龋相比，Icon渗透的人工龋更容易受到食物色素的影响。
