BACKGROUND
Smile plays an essential part in facial esthetics. There have been some mathematical and geometric theories regarding smile designing in literature. The purpose of the study was to assess RED proportion and golden proportion among patients attending a tertiary care centre at Kochi, Kerala.
METHODS
Standardised frontal images of 106 subjects, 50 male and 56 females, were captured in the age bracket of 18-25 years. Pictures of the patients were obtained using a DSLR camera (CANON EOS-60D) and then digitally analysed. Measurements of each maxillary anterior tooth was recorded and then the theories of RED and golden proportion were employed and the figures recorded were statistically analysed.
RESULTS
The RED proportion was observed to be inconsistent, while progressing distally, Golden proportion was observed to be in 6-29% of the existing subject population.
CONCLUSION
Within the limited sample size of the study, RED (Recurring Esthetic Dental) proportion and golden proportion failed to exist in Keralites.
背景
微笑在面部美学中起着至关重要的作用。文献中已有一些关于微笑设计的数学和几何理论。本研究的目的是评估喀拉拉邦科钦一家三级护理中心患者的RED比例和黄金比例。
方法
采集了106名年龄在18至25岁之间的受试者（50名男性和56名女性）的标准化正面图像。使用数码单反相机（佳能EOS - 60D）获取患者的照片，然后进行数字分析。记录每颗上颌前牙的测量数据，接着应用RED和黄金比例理论，并对记录的数据进行统计分析。
结果
观察到RED比例在向远中方向推进时不一致，而黄金比例在现有研究对象群体中的占比为6%至29%。
结论
在本研究有限的样本量范围内，喀拉拉人中不存在RED（重复美学牙科）比例和黄金比例。
