摘要
目的:研究乌鲁木齐市维吾尔族青年上前牙天然牙的色度值,为临床制作仿真修复体提供参考。方法:采用数码相机及计算机色度分析系统采集、分析852颗18~25岁乌鲁木齐市维吾尔族青年上前牙天然牙的色度值。结果:维吾尔族青年的上颌中切牙颈、中、切的L值分别为73.27±6.43、75.51±5.59、66.92±5.58,侧切牙颈、中、切的L值分别为67.06±7.50、68.43±8.38、62.11±6.99,尖牙颈、中、切的L值分别为59.62±11.60、60.40±9.10、55.11±8.73。结论:乌鲁木齐市18~25岁维吾尔族青年的上前牙色度值从中切牙向尖牙方向均呈现明度逐渐降低,彩度逐渐增大;各个牙位的不同部位牙面的色度值也有变化,其中中1/3的明度值最大、彩度值最小,颈1/3的明度值和彩度值均高于切1/3。
Objective:To study the color of Uygur youth's anterior teeth.Methods:Maxillary anterior teeth of 18-25 years' old Uygur youth were included.Color analysis system of digital camera and computer was used to measure the color of maxillary anterior teeth.Results:The L values of cervical,middle and incisal parts of uygur youngth's upper center incisor's were 73.27±6.43,75.51±5.59,66.92±5.58.Those of the upper lateral incisors were 67.06±7.50,68.43±8.38,62.11±6.99.Those for the upper canines were 59.62±11.60,60.40±9.10、55.11±8.73.Conclusion:In Urumqi,18-25 year-old uygur youth presented the color distributing of maxillary anterior form upper central incisor to cuspid,L values change from high to low,and a,b values from low to high.The color in different areas of teeth were different:in middle 1/3,L values were the highest,but a and b values were the lowest;the L,a and b values in cervical 1/3 were higher than those in incisal 1/3.
