Abstract:

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 between colorimetric 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* value was 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 the vermilion was negatively correlated with its a* value, positively correlated with its b* value, positively correlated with L* value of cheek skin and negatively 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 the vermilion, and negatively correlated with its b* value. In summary, we preliminarily determine the colorimetric value range of the facial skin and vermilion, as well as their relevance, which provide a basis for prosthesis production and choice of colors in clinic.
