To evaluate the staining effect of different children's health drinks (Boost, Complan, and Pediasure) on esthetic restorative materials (giomer, nanohybrid composite, and ormocer).
The specimens consist of giomer, nanohybrid composite, and ormocer. Before the discoloration process, 80 disks of each material were fabricated, each measuring 5 mm in diameter and 2 mm in thickness. These disks were then measured for lightnessred/greenblue/yellow (Lab*) values. Around 10 samples from each subgroup were then submerged in each of the four staining solutions. Analysis of discoloration levels was done at baseline and 48 hours after immersion in the staining solution. Each specimen's staining effect was evaluated using a spectrophotometer.Each specimen's Lab* values were measured three times by placing it on the measurement head. The internal energy (ΔE) unit, which expresses resistance to the staining effect, was derived using each specimen's Lab* values.
All the tested materials showed a color change. However, giomer showed greater ΔE values compared to nanohybrid composite and ormocer. Of all the immersion media used, Boost samples resulted in the highest color change, followed by Complan, Pediasure, and milk.
Out of the three restorative materials used in the study, ormocer showed more resistance to color change than nanohybrid composite and giomer with all the tested media.

评估不同儿童健康饮品（宝矿力水特、康宝莱营养奶昔和雅培小安素）对美学修复材料（聚硅烷增强型玻璃离子、纳米混合复合树脂和有机陶瓷）的染色效果。
样本包括聚硅烷增强型玻璃离子、纳米混合复合树脂和有机陶瓷。在变色过程开始前，每种材料制作80个圆盘样本，每个圆盘直径5毫米，厚度2毫米。然后测量这些圆盘的明度红/绿蓝/黄（Lab*）值。接着从每个亚组中选取约10个样本，分别浸泡在四种染色溶液中。在基线以及浸泡染色溶液48小时后，对变色程度进行分析。使用分光光度计评估每个样本的染色效果。将每个样本放置在测量头上，对其Lab值进行三次测量。利用每个样本的Lab值得出表示抗染色效果的色差值（ΔE）单位。
所有测试材料均出现颜色变化。然而，与纳米混合复合树脂和有机陶瓷相比，聚硅烷增强型玻璃离子的色差值更高。在所有使用的浸泡介质中，宝矿力水特样本导致的颜色变化最大，其次是康宝莱营养奶昔、雅培小安素和牛奶。
在该研究使用的三种修复材料中，对于所有测试介质，有机陶瓷比纳米混合复合树脂和聚硅烷增强型玻璃离子更耐颜色变化。
