Abstract

著者는 全身狀態, 口腔狀態 및 咬合狀態가 良好한 混合齒列期의 韓國人學童中 10.3歲와
10.4歲의 男·女各 67名과 68名의 X線頭部側貌規格撮影像에서 硬·軟組織間의 特性과 性差
를 分析·觀察하여 다음의 結論을 얻었다.
1. 一般的으로 鼻構成要素들은 男子가 女子보다 큰 傾向을 보였고 코의 높이와 길이에서
統計學約有意性이 있었다.
2. 軟組織의 肥厚度는 鼻部와 A點上에서 가장 높았으며 部에서 다음으로 높았고 前頭
部에서 가장 낮았다. 한편 上·下脣의 肥厚度는 女子에 比하여 男子가 큰 傾向이 있으며 A
點上의 肥厚度는 性差가 컸다.
3. Esthetic line에 對한 上脣에서의 突出程度는 男子가 女子보다 甚하였으며 下脣에서는
性性差가 없었다.
4. 上顔面部의 硬組織은 性差가 없었으나 軟組織에서는 鼻構成要素中一部에서 性差가 있
었다.

A study was made to investigate a relationship existing in the dentoskeletal
framework and the soft tissue profile around the face, and compare the sexual
differences between boys and girls having the normal occlusion in the mixed dentition.
The lateral cephalograms were composed of 67 boys aged 10.3 years and 68 girls
aged 10.4 years, respectively.
By means of the lateral cephalograms, both the hard-and softs tissue structures were
simultaneously analysed, measured and evaluated by introducing the several reference
items: S-N plane, palatal plane, mandibular plane, N-A line and A-P line for the
dentoskeletal structures and N'-P' line for the soft tissue, and the 21 measuring points
for the both structures.
The significant findings were as follows :
1. In general the boys showed tale larger nasal component dimension than did the
girls, but the length and height of nose(N'-Prn and NA-Prn) showed the significant
sexual difference among those when evaluated statistically.
2. The lip-thickness was found to be minimal in the region of nasion, greater in the
region of pogonion, and much greater in the region of point A in the both sexes, but
the only thickness over point A(A-A') showed the significant sexual difference
statistically.
3. The upper and lower lip position were found to be located anteriorly to the esthetic
line in the both sexes, but upper lip position showed the significant sexual difference
when evaluated statistically.
4. The regions of nose and upper lip had a tendency not to be following the
underlying skeletal profile.
