The purpose of this study was to investigate whether 3D Master or VitaLumin shade guides could improve colour selection in individuals with normal and defective colour vision. First, colour perception of 260 dental students was evaluated. Afterwards, 9 colour blind and 9 matched normal subjects tried to detect colours of 10 randomly selected tabs from each kit and the correct/false answers were counted. Of the colour-defective subjects, 47.8% and 33.3% correctly detected the shade using 3D Master and VitaLumin, respectively. These statistics were 62.2% and 42.2% in normal subjects. In normal participants, but not in colour blind ones, 3D Master significantly improved shade matching accuracy compared to VitaLumin.
本研究的目的是调查3D Master比色板或VitaLumin比色板能否改善色觉正常和色觉缺陷个体的颜色选择。首先，评估了260名牙科学生的色觉。之后，9名色盲受试者和9名相匹配的色觉正常受试者尝试从每个套装中检测10个随机选择的色片的颜色，并统计正确/错误答案。在色觉缺陷受试者中，分别有47.8%和33.3%的人使用3D Master和VitaLumin正确检测到了色度。在色觉正常受试者中，这两个统计数字分别为62.2%和42.2%。在色觉正常的参与者中，与VitaLumin相比，3D Master显著提高了色度匹配的准确性，但在色盲参与者中并非如此。
