目的：评价人工老化后不同厚度瓷聚体与不同类型树脂黏固材料联合体的颜色稳定性，为临床合理选择和应用瓷聚体贴面以及粘接剂提供参考。方法3种厚度（1.00、0.75、0.50?mm）瓷聚体Ceramage分别与光固化树脂水门汀RelyX?Veneer、双固化树脂水门汀RelyX?Unicem和流动树脂Filtek?Z350?Flow共3种类型树脂黏固材料制备瓷聚体—树脂黏固材料联合体样本，共9组（每组5个样本）。所有样本同时放入氙灯老化仪中进行人工加速老化，采用分光光度仪测量老化前后样本的明度（L*）、红绿色品（a*）和蓝黄色品（b*）值，计算老化前后明度变化（ΔL）、红绿色品变化（Δa）、蓝黄色品变化（Δb）和色差（ΔE）。用双因素方差分析探讨瓷聚体厚度和树脂黏固材料类型对老化前后ΔE的影响。结果瓷聚体厚度及树脂黏固材料类型对联合体老化前后ΔE均有影响，且两者间存在交互作用（P<0.05）。所有组ΔE均小于3.3，老化后L*、?a*、b*值均降低，且ΔL均小于2.0。结论瓷聚体厚度与树脂黏固材料类型对瓷聚体—树脂黏固材料联合体的颜色稳定性有影响；联合体老化后的明度变化和色差均在临床可接受的范围内。

The change of lightness (ΔL), red green color value (Δa), blue yellow color value (Δb), and color variation (ΔE) were also calculated.
