汉族、维族和哈萨克三民族唇红颜色调查与对比

Comparisons of color of the vermilion among Uygur,Kazak and Han ethnicities in Xinjiang China

目的测量汉、维、哈三民族上下唇红颜色并进行对比,以期为医学美学、口腔修复、牙科材料开发以及人类学研究提供基础数据。方法用PR-650分光光度计测定了汉、维、哈三民族18～22岁的在校学生,共计429人的上下唇红颜色,按照性别和民族进行分组。为了清楚地表达色度属性,表色系统采用了CIELCh体系。结果获得了汉维哈三个民族男性和女性的上下唇红的具体色度数值范围。结论汉维哈三个民族的唇红颜色可以被测色仪准确测定,唇红色存在性别差异和民族间差异,上下唇红的之间的颜色差异尤其明显。结果提示了唇红颜色差异可能与人种有关。

Objective To study the color space distribution of vermilion in Han, Uygur and Kazak ethnicities and to offer basic DATA to medical aesthetic, dental prothodentic, dental material and anthropological study. Methods Four hundred and twenty- nine Han, Uygur and Kazak medical students aged 18 -22 were included. The color of vermilion in the subjects was measured by PR - 650 spectrophotometry and expressed through the CIELCh system. All DATAs were grouped by gender and ethnicity. Results Mean ＋ SD for L ＊ ab （ value）, C ＊ ab （chroma） and H°ab （hue） of upper and lower vermilion in these three ethnicities were obtained. Condusion The color of vermilion can be measured by spectrophotometry. The color of upper vermilion differed significantly from that of lower vermilion, there were significant differences in the color of vermilion between genders and among Uygur, Kazak and Han ethnicities. It prompts that physiological structure, hemoglobin and melanin maybe the most important factor to the color of vermilion.
