The Lab*, Cab*, Hab0, values of subjects' anterior teeth, upper and lower vermilion, attachment gingiva were measured.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSIONS</b>There was a specific color space distribution pattern in oral soft and hard tissue in Uygur youth.
