摘要：

目的基于HSB色彩模型,测量牙齿各区域的色相(H)、饱和度(S)、亮度(B)数值,探寻牙齿各区域颜色变化规律。方法收集65例患者的65颗右上颌中切牙。利用拾色器工具避开反光区对右上颌中切牙的颈部、中部、切缘牙体颜色进行测量,按公式计算总体色彩参数及各区域色彩参数与总体的相对差异。最后,对计算结果进行统计,寻找牙齿各部位颜色变化规律。结果结果显示,在同一颗右上颌中切牙,颈部、中部、切缘的色相、饱和度、亮度较牙齿总体色彩参数均有所区别。在同一颗右上颌中切牙,颈部与中部的色相差异以及中部与切缘的色相差异具有统计学意义;颈部、中部、切缘的饱和度差异均具有统计学意义;颈部与切缘、中部与切缘的亮度差异也具有统计学意义。结论右上颌中切牙各区域的色彩具有差异性。在同一颗右上颌中切牙,中部色相最偏黄,颈部和切缘色相偏红;颈部的饱和度最高,中部次之,切缘饱和度最低;切缘亮度最低。

Abstract:

Objective Based on the HSB color model, the hue(H), saturation(S) and brightness(B) values of each region of the teeth were measured to explore the color change rule. Methods A total of 65 patients with 65 right maxillary central incisors were included in this study. The color of the cervical, middle and incisal regions of the right maxillary central incisors were measured using a color picker tool, avoiding reflective zones. The overall color parameters and the relative differences between each region and the overall tooth were calculated. Finally, results of the calculations were tallied to find rules of color change in three regions of the teeth. Results The results showed that in the same right maxillary central incisor, the cervical, middle and incisal regions differed in hue, saturation, and brightness compared to the overall color parameters of the teeth. In the same right maxillary central incisor, the differences between the hue of the middle region and the hue of the other two regions were statistically significant. Moreover, the differences in saturation between the cervical, middle and incisal regions were statistically significant. The difference in brightness between the cervical region and incisal region, and the difference in brightness between the middle region and the incisal region were also statistically significant. Conclusion There is variability in the color of three regions of the right maxillary central incisor. In the same right maxillary central incisor, the middle region has the most yellowish hue; the hue of the the cervical region and the incisal region are reddish. The cervical region is the most saturated; the middle region is the second most saturated, and the incisal region is the least saturated. The brightness of the incisal region is the lowest.
