摘要：

背景：国内外多数研究认为牙齿颜色会因年龄的改变而变化。
目的：分析氟斑牙色度值与年龄及性别的关系。
方法：从贵州省氟中毒人群中随机抽取氟斑牙患者317例，共计634颗上颌中切牙，用Shade Eye-NCC电脑测色仪测定患者氟斑牙色度学各要素(明度L*、色相a*、彩度b*)值，采用SPSS 15.0统计软件进行统计分析。
结果与结论：①氟斑牙色度值在不同性别间的差异有非常显著性意义(P < 0.01)。男性L*值略低于女性，a*、b*值则高于女性。②氟斑牙色度值在不同年龄组间的差异有显著性意义(P < 0.05)。L*值与年龄呈负相关关系，a*、b*值与年龄呈正相关关系。说明氟斑牙色度值在不同性别和年龄间有差异，男性氟斑牙颜色较女性暗且偏红偏黄，随着年龄增加，牙齿颜色逐渐变暗、偏黄。

Abstract:

BACKGROUND: A large number of studies at home and broad have shown that the color of teeth will be changed as age increases.
OBJECTIVE: To analyze the relationship of the chroma value of dental fluorosis with age and gender.
METHODS: A total of 317 dental fluorosis patients with 634 maxillary central incisors were randomly selected from the endemic fluorosis residents in Guizhou Province. The L*, a* and b* (brightness, hue, chroma) values of the teeth were measured by a computer-aided Shade-Eye NCC colorimeter, and the data were analyzed with SPSS 15.0 software.
RESULTS AND CONCLUSION: ①There was a significant difference in the chroma value of dental fluorosis between male and female (P < 0.01). The value of L* in male was slightly lower than that in female, while the values of a* and b* in male were higher than that in female. ②There was a significant difference in chroma values among different ages (P < 0.05). There was a negative correlation between the value of L* and age, while the values of a*, b* and age showed a positive correlation. These results suggest that there is a difference in the chroma value of dental fluorosis between different genders and ages. Compared with female, male tooth color of dental fluorosis is darker, redder and yellower, besides, tooth color will be darker and yellower gradually as age increases.
