Statement of problem: The meaning of the beauty has a little different nature according to a time, culture, and nation.
Purpose : This study was undertaken to estimate the geometric esthetic criteria for Korean woman by analysis of facial photograph in a smiling.
Material and methods: The facial photographs of 678 Korean beautiful woman were collected from Miss Korea candidates(from 1971 to 2003 year). The dento-facial composition was measured and analyzed geometrically on computer monitor using Adobe(R) Photoshop(R) 7.0. The statistical significance of the differences among the 4 decade groups was estimated by a x2 test.
Result : The Korean beautiful woman skewed the geometric characteristics such as the ’’coincidence’’ (83.0%) between facial midline and dental midline, the ’’normal’’ (96.9%) alignment and arrangement of upper anterior teeth. the ’’average’’ (79.1%) position and ’’upward’’ (53.4%) curvature of upper lip, the ’’parallel’’ (85.7%) relationship between the lower lip and upper anterior incisal curvature, the ’’touching’’ (49.9%) and ’’not-touching’’ (44.8%) relationship between upper anterior incisor and towel lip, the ’’first premolar’’ (54.1%) and ’’second premolar’’ (38.9%) displayed in a smile, and the ’’symmetry’’ (89.4%) of smile. There was statistical significance among the 4 decades in the respect of the upper lip curvature, the relationship between upper anterior incisor and lower lip, and the most posterior teeth displayed in a smile (p<0.05).
Conclusion : The Korean beautiful woman showed similar results to the western esthetic criteria in the some respects and the tendency that the Korean woman had more active smiling recently.
