The color accuracy of resin composite cements and their corresponding try-in pastes was assessed. Three shades of three brands were compared using the cements alone and in contact with a standard porcelain disk. There were significant differences in color between resin cements and their corresponding try-in pastes. The addition of a 1-mm-thick porcelain disk greatly reduced the apparent color differences. The color of resin cements changed over time, but not significantly. Baseline measurements of resin cement colors were compared and measurements made after 24 hours of storage. Color changes were statistically significant but not perceptible, and all samples became slightly darker with age.
评估了树脂复合水门汀及其相应试戴糊剂的颜色准确性。使用三种品牌的三种色号，分别单独使用水门汀以及使其与标准瓷盘接触进行比较。树脂水门汀与其相应试戴糊剂之间存在显著的颜色差异。添加1毫米厚的瓷盘可大大减少明显的颜色差异。树脂水门汀的颜色随时间变化，但变化不显著。比较了树脂水门汀颜色的基线测量值与储存24小时后的测量值。颜色变化具有统计学意义，但不可察觉，并且所有样品随着时间推移都略有变深。
