The purpose of this study was to investigate effect of various layer thicknesses on color changes of light-cured resins, Four light-cured resins with different shades ; EsteliteΣ(Tokuyama Dental, ESOA2, ESA2), Gradia Direct(GC Corp., GDAO2, GDA2), Filtek Supreme (3MESPE, FSA2D, FSA2E), Solare (GC Corp., SOAO2, SOA2) were used. Resin disks (8mm in diameter with different thickness (0.1-4.0 mm.) were prepared. Colorimetric values of the specimens were measured immediately after curing against three colored plate using a fast spectro-photometer (CMS-35FS/c, Murakami Shikisai). The CIE L^*a^*b^* color system was used for the determination of the color.The data was subjected to Tukey HSD test (α=0.05).The results were as follows ;1. The thickness of the resin composite which was not influence by the white and black colored plates background was 2.0 mm for OA2 shade of ES and GD and 3.0 mm for FSA2D. These opaque shade resins exhibited acceptable masking effect against any background colors.2.As for the single layer disk which is not influenced color, color-shielding effect was accepted in order of GDAO2,GDAO2,FSA2D, ESOA2,ESA2,SOA2,FSA2E and GDA2.3. Two layer that could mach the color of A4 plate as well as reproduce A2 color was obtained with the combinations of 1.5 mm thickness of GDAO2 shade and 0.2 or 0.3 mm thicknesses GDA2.4. It was shown that this study is effective as how to evaluate color mach stability.

本研究的目的是研究各种层厚度对光固化树脂的颜色变化的影响。具有不同色调的四种光固化树脂：Estelite ®（Tokuyama Dental，ESOA 2，ESA 2）、Estelite Direct（GC Corp.，GDAO 2、GDA 2）、Filtek Supreme（3MESPE、FSA 2D、FSA 2E）、Solare（GC Corp.，SOAO2、SOA2）。树脂圆盘（直径8 mm，厚度0.1-4.0 mm）制备了在固化后立即使用快速分光光度计（CMS-35 FS/c，Murakami Shikisai）对三色板测量试样的色度值。颜色测定采用CIE L^*a^*B^* 色度系统，数据经Tukey HSD检验（α=0.05），结果如下：1.不受白色和黑色板背景影响的树脂复合物的厚度对于ES和GD的OA 2色调为2.0 mm，对于FSA 2D为3.0 mm。2.对于不受颜色影响的单层光盘，颜色屏蔽效果从好到坏依次为GDAO 2、GDAO 2、FSA 2D、ESOA 2、ESA 2、SOA 2、FSA 2 E和GDA 2.3。用1.5mm厚的GDAO 2色调和0.2或0.3mm厚的GDA 2.4色调的组合获得了既能再现A2色又能与A4板的颜色相匹配的两层。结果表明，本研究对于评价颜料的色稳定性是有效的。
