将两种光活化的和三种热聚合的树脂基饰面材料暴露于50 ℃的煮咖啡、过滤咖啡或茶中，并评价颜色稳定性。还评估了在37摄氏度的黑暗中浸入蒸馏水中4个月的样本。其中一种光活化的树脂基饰面材料在蒸馏水和染色溶液中长期浸泡期间发生固有变色。茶叶对其他材料的变色主要是由于着色剂的表面吸附。咖啡变色是由于吸附，也吸收着色剂的两种材料的研究。着色剂吸收和渗透到贴面材料的有机相中可能是由于聚合物相与咖啡的黄色着色剂的相容性。
Two light-activated, and three heat-polymerized, resin-based veneering materials were exposed to boiled coffee, filtered coffee, or tea at 50 degrees C and evaluated for color stability. Specimens immersed in distilled water in the dark at 37 degrees C for 4 months were also assessed. One of the light-activated, resin-based veneering materials underwent intrinsic discoloration during the long-term immersion both in distilled water and in the staining solutions. The discoloration of the other materials by tea was mainly due to surface adsorption of the colorants. Discoloration by coffee was due to adsorption, and also to absorption of colorants by two of the materials investigated. This absorption and penetration of colorants into the organic phase of the veneering materials were probably due to compatibility of the polymer phase with the yellow colorants of coffee.
