The aim of the present investigation is to identify tooth shade among a group of Sudanese patients.
Total number of patients was 227. Participant's age ranged from 15 to 72 years, which, was divided into four groups. The tooth included in the study was either right or left sounds maxillary central incisor. Vita Easyshade was used to select the tooth shade. Investigation of the differences of Commission International de l'Eclairage (CIELab) coordinates among gender and state of origin was conducted together with an examination of the relationship between CIELab coordinates and age. One-way analysis of variance was used to test the differences in L*, a* and b* according to state of origin.
Results showed that A3 was the most common classical tooth shade respectively. There was highly significant difference in L* between males and females (P = 0.002). There was a significant relation between tooth shade and age (P = 0.026). There was a high significant association between classical tooth shade and Sudan regions (P = 0.00).
In conclusion, most common classical shade was A3, women's teeth were lighter than men's. There was a relation between ethnic background and tooth shade.
本研究旨在确定一组苏丹患者的牙齿颜色。
患者总数为227名。参与者年龄在15至72岁之间,分为四组。纳入研究的牙齿为右上或左上上颌中切牙。使用Vita Easyshade选择牙齿颜色。对国际照明委员会(CIELab)坐标在性别和籍贯之间的差异进行了调查,并研究了CIELab坐标与年龄之间的关系。采用单因素方差分析来检验根据籍贯划分的L*、a和b的差异。
结果表明,A3分别是最常见的经典牙齿颜色。男性和女性之间的L*存在高度显著差异(P = 0.002)。牙齿颜色与年龄之间存在显著关系(P = 0.026)。经典牙齿颜色与苏丹各地区之间存在高度显著关联(P = 0.00)。
总之,最常见的经典颜色是A3,女性的牙齿比男性的牙齿颜色更浅。种族背景与牙齿颜色之间存在关系。
