摘要

目的:采用视觉选色法对上颌中牙颜色进行评分,探讨视距对颜色选择的影响,并探讨牙齿颜色与患者年龄的关系。材料与方法:上颌中牙颜色由一名操作者在35 cm和70 cm两种不同距离采用目测法测定,共100名年龄在20-80岁之间的不同性别。在2个不同的观看距离下,使用VITA牙齿指南3D-MASTER色标仪记录牙齿的值、色调和年龄。视觉颜色的选择是在自然光下进行的,最好是在早上10点到12点之间。受试者在眼平位观察,所有颜色评估均快速完成(5-7 s)。独立组采用独立t检验,依赖组采用卡方检验。结果:考虑到亮度与距离的关系,35 cm和70 cm处的亮度值有显著差异。我们观察到,当70厘米的测量值与35厘米的测量值相比,亮度增加了。随着年龄的增长,亮度值最高的亮度值1的比值减小,较暗的亮度值3和亮度值4的比值增大。与20-39岁年龄组相比,40-59岁和60岁以上年龄组的R(红色)色调更高。结论:观察到在70厘米处测量的牙齿颜色比在35厘米处测量的牙齿颜色浅。在35厘米处确定颜色是很重要的,这样就不会选择不正确的明度(值)。可以说,随着年龄的增长,牙齿颜色越来越深,红、黄的色调也越来越浓。

The effect of the viewing distance on determination of the relationship between age and tooth color
Aim: This study aims to question the effect of visual distance on color selection by scoring the maxillary central tooth color with the visual color selection method and to investigate the relationship between tooth color and patient age. Material and Methods: Maxillary central tooth color was determined by a single operator using visual methods from two different distances, 35 cm, and 70 cm, in a total of 100 people between the ages of 20-80 and of different genders. The value, hue, and ages of the teeth were recorded using the VITA Toothguide 3D-MASTER color scale at 2 different viewing distances. Visual color selection was made in natural daylight, preferably between 10:00 and 12:00 in the morning. Subjects were observed at eye level, and all color assessments were performed rapidly (5-7 s). Independent T-test was used for independent groups and the Chi-square test was used for dependent groups. Result: Considering the relationship of lightness with distance, there is a significant difference between the values ​​at 35 cm and 70 cm distances. It was observed that the lightness increased when the measurements made from 70 cm were compared with the measurements made from 35 cm. As the age increases, the ratio of the brightness value of 1, which is the highest lightness, decreases, and the ratio of the darker 3 and 4 lightness increases. R (reddish) hue was higher in the 40-59 and over 60 age groups compared to the 20-39 age group. Conclusion: It was observed that the tooth color was determined lighter in the measurements made from 70 cm compared to the measurements made from 35 cm. It is important to determine the color at 35 cm so that the incorrect lightness (value) is not selected. It can be said that as the age increases, the tooth gets darker, and the reddish and yellowish hue increases.
