Abstract:
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 L*ab, C*ab, H*ab values of subjects' anterior teeth, upper and lower vermihon, attachment gingiva were measured. Results The mean and distribution of L*ab, C*ab, H*ab, values of Uygur youth' anterior teeth were obtained. The L*ab values of attachment gingiva,upper and lower vermilion in male were 50. 50±3. 59, 41.92±4. 10,45.02±3.06,and C*ab were 29.94 ± 3.21,27.00 ± 2.47,30.35 ± 2.67, and H*ab were 30. 00 ± 3. 27,31.71 ± 3.69,27. 73 ± 3.27, respectively. The L*ab values of attachment gingiva, upper and lower vermilion in female were 54. 28 ± 5.06,41.73 ± 3.70,47. 27 ± 2. 97, and C*ab were 27. 98 ± 3.93, 27.23 ± 2. 42,31.22 ± 2. 59, and H*ab, 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.
