To determine if Farnsworth-Munsell 100 Hue Test, Perceptual Ability Test, gender, age, ethnicity, and time predict dental shade matching and value discernment in first-year dental students.
Farnsworth-Munsell 100 Hue Test was administered to 95 first-year-dental students beneath a Judge II booth (color temperature of 6500°K, and color rendering index of 90). Students also arranged 16 masked shade tabs from a Vita Classic shade guide by value (lightest to darkest) and matched together 16 pairs of masked shade tabs from two Vita Classic shade guides. Ethnicity, age, Perceptual Ability Test scores, gender, and time to complete the tests were recorded. Associations and correlations were investigated using chi-square, Tukey-Kramer HSD, standard least square, and multilinear regression (p < 0.05).
Total error scores on the Farnsworth-Munsell 100 Hue Test ranged from 0 to 144. Forty-eight students exhibited superior color acuity, 45 average, and two poor. The mean number of correct answers for matching shade tabs together was 11.6, and 6.1 for arranging the shade tabs by value. Females performed statistically better than males on the Farnsworth-Munsell 100 Hue Test and shade tab matching. Better color discrimination identified by lower total error scores on the Farnsworth-Munsell 100 Hue Test was directly correlated to greater ability to match shade tabs together. Perceptual Ability Test scores had slight significance. As the scores increased there was slightly better performance on the Farnsworth-Munsell 100 Hue Test. Older participants performed better than younger subjects on the value test. No other correlations were significant for any of the tests.
Females and individuals who performed better on the Farnsworth-Munsell 100 Hue Test have improved dental shade-matching ability.
确定 Farnsworth-Munsell 100 色调测试、感知能力测试、性别、年龄、种族以及时间是否可预测牙色匹配和值辨别能力，这些能力在牙科学一年级学生中表现如何。
在 Judge II 亭下（色温为 6500°K，显色指数为 90），对 95 名牙科学一年级学生进行 Farnsworth-Munsell 100 色调测试。学生还根据明度（从最亮到最暗）将 Vita 经典比色板中的 16 个遮罩色标排列在一起，并将来自两个 Vita 经典比色板的 16 对遮罩色标匹配在一起。记录种族、年龄、感知能力测试得分、性别以及完成测试的时间。使用卡方检验、Tukey-Kramer HSD、标准最小二乘法和多元线性回归分析（p<0.05）进行关联和相关性研究。
Farnsworth-Munsell 100 色调测试的总误差分数范围为 0 至 144。48 名学生表现出优异的色觉敏锐度，45 名学生表现出中等水平，2 名学生表现出较差水平。将遮罩色标匹配在一起的正确答案平均为 11.6，按明度排列遮罩色标的平均答案为 6.1。在 Farnsworth-Munsell 100 色调测试和遮罩色标匹配方面，女性的表现明显优于男性。Farnsworth-Munsell 100 色调测试中总误差得分越低，表明颜色辨别能力越好，与更好地匹配遮罩色标呈直接相关。感知能力测试得分略有意义。随着分数的增加，Farnsworth-Munsell 100 色调测试的表现也略有提高。年龄较大的参与者在明度测试中表现优于年龄较小的参与者。对于任何测试，都没有其他相关性具有统计学意义。
女性和 Farnsworth-Munsell 100 色调测试表现更好的个体在牙色匹配能力方面有所提高。
