小兒의 齒周疾患 活動性과 oral-black-pigmented Bacteroides와의 相關關係에 關한 硏究
를 위하여 8∼12세의 小兒를 對象으로 齒齷裂溝出血度가 1, 2 및 3인 환자 각각 7명씩, 齒齷
裂溝出血度가 0인 환자 7명을 正常對照群으로 하여 齒周囊 깊이 및 齒齷裂溝液 測定하고 齒
苔細菌의 형태를 觀察한 후 齒 緣下 齒苔細菌을 채취하여 37℃ 혐기성 세균 배양기內에서
혈액한 천배지에 接種하여 7일간 배양한 후 純粹分離하여 생화학적 검사를 施行하여
Bacteroides 菌株의 同定을 實施하였다.
호기성 세균 배양을 위해서는 채취된 齒苔細菌의 溶液을 37℃ 細菌 배양기에서 호기성 상
태로 48시간 배양하여 다음과 같은 결과를 얻었다.
1. 齒 裂溝出血度에 따라 齒齟裂溝液 渗出量과 運動性 桿菌은 증가하였고 球菌과 非運動
性 桿菌은 감소하였다.
2. 齒 裂溝出血度가 1인 환자군에서 호기성 세균은 전체 分離 배양 菌株의 72.6%를 차지
하였고 혐기성 세균은 27.4%를 차지하였으며 혐기성 세균中 2.4%는 black-pigmented
Bacteroides로 나타났으며 25%는 기타 혐기성 세균으로 나타났다.
3. 齒 裂溝出血度가 2인 환자군에서는 호기성 세균이 전체의 59.7%를 혐기성 세균이
40.3%를 차지하였으며 현기성 세균이 2.9%가 black-pigmented Bacteroides로 나타났고
37.4%는 기타 혐기성 세균으로 나타났다.
4. 齒 裂溝出血度가 3인 환자군에서는 호기성 세균이 전체의 17.2%를, 혐기성 세균이
82.8%를 차지하였으며 혐기성 세균中 13.3%가 black-pigmented Bacteroides로 나타났고
69.5%는 기타 혐기성세균으로 나타났다.
5. 正常對照群인 齒 裂溝出血度가 0인 환자군에서는 호기성 세균이 전체의 79.5%를, 혐
기성 세균이 20.5%를 차지하였으며 혐기성 세균中 1.1%가 black-pigmented Bacteroides로
나타났고 19.4%는 기타 혐기성 세균으로 나타났다.
6. 齒 裂溝出血度가 증가함에 따라 호기성 세균은 감소하였고 혐기성 세균은 증가하였으
며 이들 細菌中에서도 black-pigmented Bacteroides가 증가하였다.
#초록#
For the study of the relationship between oral-black-pigmented Bacteroides and
periodontal disease activity in children, 28 children of 8∼12 ages were examined with 4
groups(S.B.I : 0, 1, 2, 3). The periodontal disease activity of each site was evaluated
using S.B.I, G.C.F, and periodontal pocket depth. The proportion of coccid cells, motile
rods, nonmotile rods and spirochetes was determined by dark-field microscopy.
The subgingival plaque samples were plated onto blood agar plate and incubated in an
anaerobic chamber.
After 7 days of incubation, total number of colonies and the total number of
black-pigmented colonies were enumeratied.
Pure culture colonies were idenified by biochemical test.
The experiment showed that.
1. As the S.B.I score increased, the G.C.F flow and the proportion of motile rods was
increased significantly but the proportion of nonmotile rods and coccid cells was
decreased.
2. When the S.B.I score was 1, the mean percentage of aerobic microflora was 72.6%
and anaerobic microflora was 27.4%, the mena percentage of black pigmented
Bacteroides among total subgingival microflora was 2.4% and other anaerobic microfolra
was 25.0%.
3. When the S.B.I score was 2, the mean percentage of aerobic microflora was 59.76%
and anaerobic microflora was 40.3%, the mena percentage of black pigmented bacteroides
among total subgingival microflora was 2.9% and other anaerobic microfolra was 37.4%.
4. When the S.B.I score was 3, the mean percentage of aerobic microflora was 17.2%
and anaerobic microflora was 82.8%, the mena percentage of black pigmented
Bacteroides among total subgingival microflora was 13.3% and other anaerobic microfolra
was 69.5%.
5. When the S.B.I score was 0, the mean percentage of aerobic microflora was 79.5%
and anaerobic microflora was 20.5%, the mean percentage of black pigmented
Bacteroides among total subgingival microflora was 1.1% and other anaerobic microflora
was 19.4%.
6. As the S.B.I score increased, the proportion of aerobic microbic microflora was
decreased but the proportion of anaerobic microflora and black pigmented Bacteroides
was increased significantly.
