本研究的目的是研究不同染色溶液对间接光固化树脂复合材料色坐标的影响。采用Signum+/Haraeus-Kulzer、Sinfony/3M-Espe、GC Gradia/GC、Ena HRi/Micerium四种间接复合材料制作了112个光盘，分为四组，分别浸泡在茶、咖啡、巧克力和蒸馏水中，在37℃下浸泡4周。根据CIELAB系统测定浸泡前、浸泡后1、2、3、4周的颜色，计算各浸泡期的ΔL*、Δa*、Δb*、ΔE*值。时间、溶液和材料对主次色坐标的影响采用双向重复方差分析和两两比较估计，a = 0.05。结果表明，咖啡对所有材料的影响都很强（p < 0.05），其次是茶和巧克力。交响乐的颜色变化最大（p < 0.05），这是由于b*和L*坐标的变化。颜色坐标受材料类型和溶液的影响不同。总之，本研究表明，间接树脂复合材料的颜色受到所有三个检查因素（浸泡时间，染色溶液和材料类型）的影响，即使从第一周开始，其临床可接受水平（ΔΕ* > 2.7 U），并且在第二，第三和第四周达到不可接受水平（ΔΕ* > 5.5 U），具体取决于染色溶液和材料。
The purpose of this study was to investigate the effect of different staining solutions on the color coordinates of indirect light-cured resin composites. 112 discs were made using four indirect composites, Signum+/Haraeus-Kulzer, Sinfony/3M-Espe, GC Gradia/GC, Ena HRi/Micerium, and divided into four groups which immersed in tea, coffee, chocolate and distilled water, at 37 °C, for 4 weeks. The color, before and after immersion for 1, 2, 3 and 4 weeks, was measured according to CIELAB system and ΔL*, Δa*, Δb* and ΔE* values were calculated for all immersion periods. The effect of time, solution and material on primary and secondary color coordinates was estimated using two-way repeated ANOVAs and pairwise comparisons, at a = 0.05. The results showed that coffee strongly affected all the materials (p < 0.05), followed by tea and chocolate. Sinfony presented the highest color change (p < 0.05), due to changes in b* and L* coordinates. Color coordinates were affected differently by material type and solution. In conclusion, this study showed that the color of indirect resin composites was affected by all three examined factors (immersion time, staining solution and material type), in a clinically appreciable level (ΔΕ* > 2.7 U) even from the first week, and in an unacceptable level (ΔΕ* > 5.5 U) in the second, third and fourth week, depending on the staining solution and the material.
