title: [Investigation of the color of anterior teeth, vermilion and attachment gingiva of 151 Uygur youth].
abstract: OBJECTIVE
  To analyze the characteristics of color of Uygur's oral soft and hard tissue.
  
  
  METHODS
  One hundred and fifty-one Uygur medical students (18 to 22 years) were included in this study. The Lab*, Cab*, Hab0, values of subjects' anterior teeth, upper and lower vermilion, attachment gingiva were measured.
  
  
  RESULTS
  The mean and distribution of Lab*, Cab*, Hab0, values of Uygur youth' anterior teeth were obtained. The Lab* values of attachment gingiva, upper and lower vermilion in male were 50.50 +/- 3.59, 41.92 +/- 4.10, 45.02 +/- 3.06, and Cab* were 29.94 +/- 3.21, 27.00 +/- 2.47, 30.35 +/- 2.67, and Hab0 were 30.00 +/- 3.27, 31.71 +/- 3.69, 27.73 +/- 3.27, respectively. The Lab* values of attachment gingiva, upper and lower vermilion in female were 54.28 +/- 5.06, 41.73 +/- 3.70, 47.27 +/- 2.97, and Cab* were 27.98 +/- 3.93, 27.23 +/- 2.42, 31.22 +/- 2.59, and Hab0 were 33.39 +/- 3.67, 32.28 +/- 3.68, 27.57 +/- 2.65.
  
  
  CONCLUSIONS
  There was a specific color space distribution pattern in oral soft and hard tissue in Uygur youth. There was a trend of decreasing lightness, increasing saturation, and red hue shifting from the center to both distal directions. There was statistical significant gender difference in color of tooth and attachment gingiva. What's more, there was extremely significant difference between upper and lower vermilion.
