The purpose of this study was to quantitatively evaluate the effects of different shades of light-polymerized resin cement on the color of two different thicknesses (0.5 mm and 0.7 mm) of three different ceramic materials (Esthetic, e.max, and ZirPress). A spectrophotometer (Color Eye 7000A - CIE (Lab*) was used to measure the color of specimens on the control substrate without cement, and then on (Translucent, White Opaque, B0.5, A1, and A3 of RelyX™ Veneer cement). The mean values of color difference (ΔE) were higher for Esthetic, followed by ZirPress, with the lowest values for e.max. The mean values of ΔE decreased when the thickness of ceramic increased from 0.5 mm to 0.7 mm. It was observed that the White Opaque had significantly increased ΔE values when compared with (TR, B0.5, A1, and A3), whereas no significant difference between B0.5 and TR, and between B0.5 and A3.
本研究旨在定量评估不同色号的光固化树脂水门汀对三种不同陶瓷材料（Esthetic、e.max 和 ZirPress）两种不同厚度（0.5mm 和 0.7mm）的颜色影响。使用分光光度计（Color Eye 7000A-CIE（Lab*）测量无水门汀的对照基底上试件的颜色，然后测量（Translucent、White Opaque、B0.5、A1 和 A3 的 RelyX™ Veneer 水门汀）的颜色。Esthetic 的色差平均值（ΔE）最高，其次是 ZirPress，而 e.max 的值最低。当陶瓷厚度从 0.5mm 增加到 0.7mm 时，平均 ΔE 值降低。观察到与（TR、B0.5、A1 和 A3）相比，White Opaque 的 ΔE 值显著增加，而 B0.5 与 TR 之间以及 B0.5 与 A3 之间无显著差异。
