摘要： 目的: 测量辽阳地区中青年恒前牙牙冠不同部位间颜色差别,指导口腔美学修复中的比色、选色。方法: 在统一标准(Ｄ65标准光源)下应用数码相机、计算机和相关软件,采用CIE-1976-L*a*b*色度系统对辽阳地区的142名中青年志愿者的852颗上颌恒前牙牙冠不同部位的颜色进行测量。结果: 辽阳中青年上颌中切牙颈、中、切的L值分别为（72.57±6.34）、（74.52±5.60）、（67.29±6.08），侧切牙颈、中、切的L值分别为（66.86±6.50）、（69.44±8.62）、（63.12±7.01），尖牙颈、中、切的L值分别为（60.52±11.70）、（61.42±9.20）、（54.12±8.37）。结论: 辽阳中青年恒上前牙牙色明度值从中切牙向尖牙逐渐降低，彩度逐渐增大；各个牙位不同部位色度值也不相同，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。

Abstract: Objective: To study the color distribution of natural anterior teeth crowns of the young and middle-aged in Liaoyang and to provide the information for color-matching in prosthetic dentistry. Methods: The study consisted of 142 people aged from 28 to 45 years and born in Liaoyang. A total of 852 healthy anterior teeth were measured with a fiber-optical spectrophotometery system. Results: The L values of cervical, middle and incisal parts of upper center incisors were （72.57±6.34）, （74.52±5.60） and （67.29±6.08）, respectively. Those of the upper lateral incisors were （66.86±6.50）, （69.44±8.62） and （63.12±7.01）, respectively. Those of the upper canines were （60.52±11.70）, （61.42±9.20） and （54.12±8.37）, respectively. Conclusion: Among upper anterior teeth of young and middle-aged people in Liaoyang，the L values decreased from upper central incisor to cuspid teeth, but the a and b values increased. The colors in different areas of teeth were variable. In middle 1/3, the L values were the highest, but the a and b values were lower; the L, a and b values in cervical 1/3 were higher than those in incisal 1/3.
