Abstract
結論
本 硏究는 乳臼齒의 咀嚼能率을 測定하기 위하여 乳臼齒가 1個 缺損된 5才에서 7才 兒童
100名을 對象으로 하여 3 gm 의 볶은 낙화생을 20回 吸嚼한 後 實驗咸績을 統計處理하여
다음과 같은 結論을 얻었다.
1. 男·女 間의 咀嚼能率에는 差異가 없었다.
2. 上, 下顎 및 左, 右側 間의 咀嚼能率에는 差異가 없었다.
3. 第 1, 2 乳黜齒 間의 咀嚼能率에는 差異가 없었다.
4. 健全部位와 比較한 缺損部位의 咀嚼能率의 減少率은 上顎 第1 乳臼齒는 34.3%, 上類
第2 乳臼齒는 29.4%, 下顎 第1 乳臼齒는 33.2%, 下顎 第2 乳臼齒는 49.2%였다.
#초록#
This study was to investigate the masticatory efficiency of the primary molar. The
subjects were consisted of 100 children which missed one tooth of 8 primary molars,
aging from 5 to 7 rears. The masticatory efficiency of the subjects was analyzed by
chewing 3 gas of the frizzled peanuts 20 times at one time and collecting the chewed
peanuts filtered by using 10, 20, 40 standard sieves in order, The ratio of the
masticatory efficiency was calculated with original volume-collected filtered volume /
original volume x100.
The results were as follows:
1. There was no difference of the masticatory efficiency in sex.
2. There was very slight difference of the masticatory efficiency between the right
and left site and the upper and lower primary molars.
3. There was very slight difference of the masticatory efficiency between the 1st and
2nd primary molars.
4. Comparing the missing region of primary molars with the presence region of the
primary molars, the masticatory efficiency of the missing region decreased at 34.3% in
upper 1st primary molar and 29.4% in upper 2nd primary molar, 33.2% in lower 1st
primary molar and 49.2% in lower 2nd primary molar.
