Abstract
|
|
|
The purpose of this study is to develop soft tissue cephalometric standards in children with normal occlusion and to determine the differences between males and females and the differences according to age ranges of 9, 10 and 11 years.
The lateral cephalometric radiographs of 169 children(82 boys, 87 girls) among the contestants in 2000-2004 Healthy Dentition Contest in Seoul were studied with several soft tissue profile analyses and cephalometric means and following results were obtained.
1. The sex differences were not statistically significant between males and females soft tissue parameters except for two soft tissue parameters(p＞0.05).
2. Females had relatively more protrusive lower lip relative to the H line than males and middle third face height to lower third face height of females was larger than males(p＜0.05).
3. The age differences in soft tissue parameters were not statistically significant according to age ranges of 9, 10 and 11 years(p＞0.05).
