唇红、面部皮肤颜色测量及其相关性

摘要

背景:在颌面部肿瘤和创伤造成的颌面部软组织缺损的修复中,赝复体仿真性至关重要.关于唇红等软组织颜色方面的研究却较少,面部皮肤和唇红颜色相关性的研究则更少.目的:采集人群唇红、面部皮肤的色度值数据,明确人群唇红、面部多个部位皮肤色度值范围及其相关性.方法:采用日本柯尼卡美能达CM-700d分光测色计采集、测定202例志愿受试者唇红、面部皮肤色度值,测定结果用CIELAB表色系统来描述,以L*值代表着明度;a*值表示颜色从绿色(-a*)到红色(+a*)之间变化, b*值表示颜色从黄色(+b*)到蓝色(-b*)之间变化;分析唇红、颊部皮肤色度值之间的相关性.结果与结论:①受试者202例人群中唇红的色度值L * 53.25±3.42,a * 11.19±1.70,b * 8.77±2.12;颊部皮肤色度值L * 61.87±3.59,a * 7.21±1.29,b * 12.98±1.64;②有牙颌人群中唇红L *值与唇红a *值呈负相关,与唇红b *值呈正相关,与颊部皮肤L *值呈正相关,与颊部皮肤a *值呈负相关;唇红a *值与颊部皮肤a *值呈正相关;唇红b *值与与颊部皮肤b *值呈正相关;颊部皮肤L *值与唇红b *值呈正相关,与颊部皮肤a *值呈负相关;颊部皮肤a *值与唇红b *值呈负相关,颊部皮肤a *值与颊部皮肤b *值呈负相关;③结果说明,通过此项研究初步得出唇红、面部皮肤色度值范围及其相关性,为赝复体制作及临床医生选色提供了依据.%BACKGROUND: Prosthesis simulation is critical for maxillofacial defects caused by maxillofacial tumor and trauma. Few studies have been reported on the vermilion color, much less the correlation between facial skin color and vermilion color. OBJECTIVE: To collect thecolorimetric values of human vermilion and facial skin, so as to determine the colorimetric value range and its relevance.. METHODS: The colorimetric values of vermilion and facial skin in 202 volunteers were measured by Japanese Konica Minolta CM-700d spectrophotometer, L* (brightness), a* (from –a* (green) to +a* (red)), b* (from –b*(yellow) to +a* (blue)) values were surveyed and calculated, and then analyzed with CIELAB color system. The correlation betweencolorimetric values of the vermilion and cheek skin color was analyzed.RESULTS AND CONCLUSION: For the vermilion color in 202 volunteers, L* value was 53.25±3.42, a* value was 11.19±1.70, and b* valuewas 8.77±2.12; for the cheek skin color, L* value was 61.87±3.59, a* value was 7.21±1.29, and b* value was 12.98±1.64. L* value of thevermilion was negatively correlated with its a* value, positively correlated with its b* value, positively correlated with L* value of cheek skin andnegatively correlated with a* value of the cheek skin. a* value of the vermilion was positively correlated with a* value of the cheek skin. b*value of the vermilion was positively correlated with b* value of the cheek skin. L* value of the cheek skin was positively correlated with b*value of the vermilion, and negatively correlated with its a* value. a* value of the cheek skin was negatively correlated with b* value of thevermilion, and negatively correlated with its b* value. In summary, we preliminarily determine the colorimetric value range of the facial skin andvermilion, as well as their relevance, which provide a basis for prosthesis production and choice of colors in clinic.
