The aim of this in vitro study was to evaluate the color change of resin composites with different filler contents subjected to immersion in different solutions, brushing, and thermal aging procedures. A total of 320 samples were prepared using 4 different flowable and 4 different conventional resin composites (n = 40). The samples were separated into 4 subgroups according to the solution to be used (wine, coffee, tea, or distilled water) and then immersed in the solutions for 12 days. All samples were subjected to 10,000 cycles of brushing and 10,000 cycles of thermal cycling procedures. ∆E values were calculated according to CIEDE2000 and CIELab color systems. For statistical analysis, the 3-way analysis of variance, the Tukey test, and the intraclass correlation coefficient were used. The significance level was taken as P < 0.05. Mean color change values differed significantly according to the solution, type of resin composite, and their interactions (P < 0.001). The values of the highest color change were obtained in wine, according to solutions, and conventional according to type. The filler content, viscosity, solutions to which they are subjected and their interactions with each other are effective factors in the color stability of restorative materials. The most effective factor in the color change of resin composites was the solution.
本体外研究的目的是评估不同填料含量的树脂复合材料在浸入不同溶液、刷牙及热老化处理后的颜色变化。使用4种不同的可流动树脂复合材料和4种不同的传统树脂复合材料制备了总共320个样本（n = 40）。根据所用溶液（葡萄酒、咖啡、茶或蒸馏水）将样本分为4个亚组，然后将其浸入溶液中12天。所有样本均进行10000次刷牙循环和10000次热循环处理。根据CIEDE2000和CIELab颜色系统计算∆E值。进行统计分析时，使用了三因素方差分析、Tukey检验和组内相关系数。显著性水平设定为P < 0.05。平均颜色变化值根据溶液、树脂复合材料类型及其相互作用存在显著差异（P < 0.001）。就溶液而言，葡萄酒中的颜色变化值最高；就类型而言，传统树脂复合材料中的颜色变化值最高。填料含量、粘度、所接触的溶液及其相互作用是影响修复材料颜色稳定性的因素。树脂复合材料颜色变化的最有效因素是溶液。
