Many restorative materials are claimed by their manufacturers to match the Vita shade guide. To verify this claim, 40 dental personnel were asked to color match five different restorative materials to their respective Vita shade tabs according to a 5-point scale (1 = very poor color match; 5 = excellent color match). Three shades were chosen for each restorative material (a mid-Value shade as well as the highest Value shade and the lowest Value shade present in each system). Pooled scores indicated that the resin composite materials had significantly better overall shade match than did the other materials evaluated and that one resin-modified glass-ionomer cement had significantly better shade match than did the "compomer" and another resin-modified glass-ionomer cement. Only 11% of the scores for all material and shade combinations were given a good or excellent rating (score greater than 3). Shade match to the Vita shade guide was not material dependent but tended to differ among the different Value shades evaluated.
许多修复材料的制造商声称其产品与Vita比色板相匹配。为了验证这一说法，研究人员要求40名牙科专业人员根据5分制（1 = 颜色匹配非常差；5 = 颜色匹配非常好），将五种不同的修复材料与各自的Vita比色片进行颜色匹配。每种修复材料选择了三种色号（每种系统中的中间明度色号以及最高明度色号和最低明度色号）。汇总分数表明，树脂复合材料的总体颜色匹配明显优于其他评估材料，并且一种树脂改性玻璃离子水门汀的颜色匹配明显优于“复合体”和另一种树脂改性玻璃离子水门汀。所有材料和色号组合的分数中，只有11%被评为良好或优秀（分数大于3）。与Vita比色板的颜色匹配不取决于材料，但在所评估的不同明度色号之间往往存在差异。
