The purpose of this study was to determine the effect of age, gender, and educational background on the color coordinates of the maxillary central incisor.
The color of the maxillary central incisor teeth of 302 individuals was measured using a spectrophotometer. The L*, a*, and b* parameters were recorded. T-tests, analysis of variance (ANOVA), and the Scheffe's post-hoc tests were used to describe the relation of the L*, a*, and b* values between color with age, gender, and educational background.
The results of this study showed that a significant difference among all three parameters of color and age was observed. There was a significant difference for the a* and b* parameters for gender, but no difference was found for the L* parameter. Finally, there was a significant difference in the L* and a* parameters, but no difference in the b* parameter in terms of educational background.
As individuals age, their tooth color darkens. Women have lighter teeth than men. The tooth color of high school graduates was found to be lighter than that of the other groups.
本研究的目的是确定年龄、性别和教育背景对上颌中切牙颜色坐标的影响。
使用分光光度计测量302名个体上颌中切牙的颜色。记录L*、a和b参数。采用t检验、方差分析（ANOVA）和谢弗事后检验来描述颜色的L*、a和b值与年龄、性别和教育背景之间的关系。
本研究结果表明，颜色的所有三个参数与年龄之间均观察到显著差异。性别方面，a和b参数存在显著差异，但L参数未发现差异。最后，就教育背景而言，L和a参数存在显著差异，但b参数未发现差异。
随着个体年龄增长，牙齿颜色会变深。女性的牙齿比男性的更亮。发现高中毕业生的牙齿颜色比其他组的更亮。
