OBJECTIVE: To analyze the characteristics of color of Uygur's oral soft and hard tissue. METHOD: One hundred and fifty-one Uygur medical students (18 to 22 years) were included in this study. The Lab*, @entity17698 *, Hab0, values of subjects' anterior teeth, upper and lower vermilion, @entity1464 were measured. RESULTS: The mean and distribution of Lab*, @entity17698 *, Hab0, values of Uygur youth' anterior teeth were obtained. The Lab* values of @entity1464 , upper and lower vermilion in male were 50.50 +/- 3.59, 41.92 +/- 4.10, 45.02 +/- 3.06, and @entity17698 * 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 @entity1464 , upper and lower vermilion in female were 54.28 +/- 5.06, 41.73 +/- 3.70, 47.27 +/- 2.97, and @entity17698 * 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 @entity1464 . What's more, there was extremely significant difference between upper and lower vermilion.
