The purpose of this study was to determine if there is an association between Perceptual Ability Test (PAT) results and color vision deficiency (CVD).
Three consecutive classes of first-year dental students (n = 291) voluntarily participated in the study. The Farnsworth-Munsell 100 Hue Color Vision test (FM-100) was administered to students beneath a Macbeth Judge II viewing booth that provided ideal lighting conditions to ascertain CVD. Results of FM-100 test were recorded as total error scores (TES). Color acuity was scored as superior (TES 0-16), average (TES 20-100), or poor (TES > 100). Additional information of age, sex, ethnicity, and time to complete the FM-100 was obtained. Multiple linear regression was used to determine the association between PAT and CVD while adjusting for age, sex, ethnicity, and time to complete the FM-100 test.
TES ranged from 0-244. There were 132 students with superior color acuity, 161 with average, and eight with poor acuity. Females performed better than males on the FM-100 test. Time to complete the FM-100 test ranged from 3:40 minutes to 25:12 minutes. There was a strong relationship between PAT scores and CVD (P = 0.0003). A 1-unit increase in PAT scores was found to result in a 9% decrease in TES; indicating that students with higher PAT scores are less likely to have CVD.
The PAT may be a preliminary screening instrument to identify students who may have CVD. The FM-100 test can then confirm the presence of CVD. Students with CVD may desire to improve dental shade matching skills through targeted training and education.
本研究旨在确定知觉能力测试（PAT）结果与色觉缺陷（CVD）之间是否存在关联。
连续三届一年级牙科学生（n=291）自愿参加了这项研究。在 Macbeth Judge II 观察亭下对学生进行 Farnsworth-Munsell 100 色调色觉测试（FM-100），以确定 CVD。FM-100 测试的结果记录为总误差分数（TES）。色觉锐度评分分为优秀（TES 0-16）、平均（TES 20-100）或差（TES>100）。还获得了年龄、性别、种族和完成 FM-100 所需时间等其他信息。使用多元线性回归来确定 PAT 与 CVD 之间的关联，同时调整年龄、性别、种族和完成 FM-100 测试所需的时间。
TES 范围从 0 到 244。有 132 名学生色觉优秀，161 名学生色觉平均，8 名学生色觉差。女性在 FM-100 测试中的表现优于男性。完成 FM-100 测试的时间从 3:40 分钟到 25:12 分钟不等。PAT 分数与 CVD 之间存在很强的关系（P=0.0003）。PAT 分数每增加 1 个单位，TES 就会减少 9%；这表明 PAT 分数较高的学生患 CVD 的可能性较小。
PAT 可能是一种初步的筛选工具，可以识别可能有色觉缺陷的学生。然后，FM-100 测试可以确认 CVD 的存在。患有 CVD 的学生可能希望通过有针对性的培训和教育来提高牙科色调匹配技能。
