1The First Affiliated Hospital of Xinjiang Medical University. Urumqi 830054, Xinjiang Uygur Autonomous Region, China.
Purpose:
In order to provide reference for orthodontic and esthetic dentistry, we measured anterior teeth widths, and analyzed the ratio between the teeth in 236 Uygur teenagers.
Methods:
Two hundred and thirty-six samples were selected from Uygur population,Vernier calipers was used to measure the widths of the anterior teeth. SPSS21.0 software package was used for independent sample t test, paired t test and REG regression.
Results:
Except for mandibular lateral incisors, significant difference was observed in anterior teeth widths between males and females, the ratio between the upper and lower central incisors in males was nearly 1.618; the ratio between upper central incisor and lower central incisor, upper central incisor and lower lateral incisor, upper canine and lower lateral incisor in females was not approaching 1.618, i.e. There was no "golden proportion". There was significant correlation between anterior teeth of Ugyur teenagers.
Conclusions:
No "golden proportion" was found in anterior teeth widths of Ugyur teenagers, but a specific ratio exists.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
