Abstract
'S'市에 居住하는 2歲에서 6歲까지의 兒童 205名(男 114, 女 91)을 對象으로 Ravn의 測定
方法에 依해 乳齒列의 齒間空隙을 統計學的으로 調査,硏究한 結果 다음과 같은 結論을 얻었
다.
1. 齒間空隙의 頻度는 上顎에서 乳側切齒와 乳犬齒間이, 下顎에서 乳犬齒와 第1乳臼齒間이
가장 높았으며 .上, 下顎 모두 乳臼齒間이 가장 낮았다.
2. 齒間空隙의 種類別 頻度는 上, 下顎 共이 靈長空隙과 함께 他部位에 空隙이 있는 境遇가
가장 높았으며 空隙의 程度는 上, 下顎 모두 S2인 境遇가 높았다.
3. 靈長空隙의 頻度는 上顎이 下顎보다 높았으며 上, 下顎 共히 兩側性인 境遇가 높았다.
4. 有隙型 齒列穹이 閉鎖穹 齒列型보다 頻度가 높았으며 閉鎖型 齒列穹中 約1/2 程度에서
crowding을 보였다.
5. 有用空隙의 크기에서 頹序는 上,下顎 共히 切齒部, 犬齒部, 乳臼齒烈 順이었으며 性別,
顎別 差異는 認定되지 않았다.
#초록#
The purpose of this study was to statistically evaluate the spacing of primary dentition
according to whether or not a space existed and measurement of amount of space in
205 children (male 114, female 91) from 2 to 6 years of age.
The results were as fellows;
1. In the incidence of interdental space on each region, spacing between the primary
lateral incisors and primary canine in maxilla and between the primary canine and 1st
primary molar in mandible showed the highest percentage, on the other hand, spacing
between the 1st and 2nd primary polars in both jaw showed the lowest percentage.
2. In the kinds of interdental space, the state of primate space and other space together
showed the highest percentage, and in the degree of spacing, S2 showed
the highest percentage in both jaw.
3. In the incidence of primate space, maxillary primate space showed higher percentage
than mandibular primate space in bilateral case.
4. In the type of arch form, spaced arch showed higher percentage than closed arch
and about the haw of closed arch showed crowding.
5. In both Jaw, available space showed incisor segments, canine segments, and
premolar segment in order of amount, and there were not statistically significant
differences of sex or jaws in the amount of available space.
