The color is a psychophysical phenomenon, and much has been studied about its physical components. However, the psychological part is poorly investigated, except for the difference between genders in the literature shows that more men are color deficient than women. Dental students are trained to better understand the differences in color, so we became interested in studying whether psychological variables such as anxiety and depression and use of hormonal contraceptives may interfere with this ability. The aim of this in vitro study was to investigate if factors, such as, hormonal contraceptive use, depressive symptoms, anxiety and quality of life, influence on the ability of color discrimination of dental school students.
Sixty-one subjects participated and the following instruments apply: (1) test that consists in the observation of a set of 25 labels (Pantones) with values of known colors, (2) scales of depression, anxiety, and quality of life assessments, and (3) Ishihara test.
No difference was observed between genders as color perception (p = 0.868). Symptoms of anxiety and depression were significantly more frequent in the female population that showed worse quality of life (p < 0.000) but did not interfere with color perception. Women using hormonal contraceptives had lower color perception than men (p = 0.04).
No difference between the genders in the perception of colors was observed, contrary to common sense that women discriminate more colors than men, but women using hormonal contraceptives showed more difficulty in color perception.
The ability to understand and distinguish color differences is extremely important in clinical dentistry. There could be differences in color perception between men and women that would influence clinical performance.
颜色是一种心理物理现象，人们对其物理成分已进行了大量研究。然而，心理部分的研究却很少，除了文献中显示的性别差异，即男性色盲患者比女性更多。牙科学生接受培训以更好地理解颜色差异，因此我们对研究焦虑和抑郁等心理变量以及激素避孕药的使用是否会干扰这种能力产生了兴趣。这项体外研究的目的是调查激素避孕药的使用、抑郁症状、焦虑和生活质量等因素是否会影响牙科专业学生的颜色辨别能力。
61名受试者参与研究，并使用了以下工具：（1）通过观察一组25个已知颜色值的标签（潘通色卡）进行测试；（2）抑郁、焦虑和生活质量评估量表；（3）石原氏色盲测试。
在颜色感知方面，未观察到性别差异（p = 0.868）。焦虑和抑郁症状在女性人群中更为频繁，且生活质量较差（p < 0.000），但这并未干扰颜色感知。使用激素避孕药的女性比男性的颜色感知能力更低（p = 0.04）。
与女性比男性能辨别更多颜色的常识相反，在颜色感知方面未观察到性别差异，但使用激素避孕药的女性在颜色感知上表现出更多困难。
理解和区分颜色差异的能力在临床牙科中极其重要。男性和女性在颜色感知上可能存在差异，这会影响临床操作表现。
