摘要
目的通过采集云南昆明地区人群上颌前牙颜色信息,分析变化规律,为临床美学修复体比色提供参考依据。方法采用VITA Easyshade Advance4.0无线电脑比色仪对云南昆明地区20~89岁300名人群,按年龄、牙位进行分组,共计1800颗上前牙(左右对称中切牙、侧切牙、尖牙),测量每颗牙中1/3区域的L^(*)a^(*)b^(*)值,用Spss24.0软件对其进行统计学分析。结果(1)左右对称同名牙间L^(*)a^(*)b^(*)值无统计学差异(P>0.05);(2)不同性别同名牙L^(*)a^(*)b^(*)值颜色差异无统计学意义(P>0.05);(3)不同牙位L^(*)a^(*)b^(*)值有统计学差异(P<0.05);(4)不同年龄L^(*)a^(*)b^(*)值存在显著性差异(P<0.05)。结论(1)云南昆明地区人群上前牙牙冠的颜色与牙位、年龄有关,与性别无关;(2)从中切牙、侧切牙到尖牙,亮度逐渐减小,色相逐渐向红、黄色过渡;(3)随着年龄的增加,上前牙明度逐渐减小,色相向绿、黄色方向过渡。建议临床进行上前牙比色时,优先选同颌对侧同名牙,如果双侧同名牙缺失,选择饱和度最高的,且在口内不易脱落的牙位即尖牙作为参考比色。
Objective To analyze the change law of the color information of maxillary anterior teeth in Kunming,Yunnan Province,so as to provide a reference basis for clinical aesthetic prosthesis colorimetry.Methods Vita easyshade advanced 4.0 wireless computer colorimeter was used to measure the L*a*b*values in 1/3 of 1800 upper anterior teeth(left and right symmetrical central incisors,lateral incisors and canines)aged 20~89 in Kunming,Yunnan.They were grouped according to age and tooth position,and statistical analysis was carried out by spss24.0 software.Results 1.There was no significant difference between left and right symmetrical homonymous teeth(P>0.05).2.There was no significant difference in color between male and female homonymous teeth(P>0.05).3.There were significant differences in L*a*b*values in different tooth positions(P<0.05);4.There was statistical difference in L*a*b*with age(P<0.05).Conclusions 1.the color of the crowns of the maxillary anterior teeth in Kunming area of Yunnan Province is related to tooth position,age and age,but not to gender.2.From central incisor to lateral incisor and canine,the brightness gradually decreases,the hue gradually changes to red and yellow.3.With the increase of age,the brightness of the upper anterior teeth gradually decreases,and the color phase transits to green and yellow.It is suggested that the teeth with the same name on the opposite side of the same jaw are preferred in clinical color comparison of maxillary anterior teeth.If the teeth with the same name on both sides are missing,the tooth position with the highest saturation,and not easy to fall off in the mouth,namely the canine,is selected as the reference color comparison.
