수종의 기계적 치태조절 방법이 치태 및 치은염에 미치는 영향에 대한 비교 연구

Abstract

[한글]

수종의 기계적 치태조절방법이 치간부위의 치태 및 치은염증에 미치는 영향에 대한 효과를 관찰하기 위하여 치과대학생 남자 30명을 선발하여 칫솔(실험1군), 칫솔과 tooth-pick(실험3군), 칫솔과 dental floss(실험4군)를 사용하였으며 칫솔질 방법으로는 Bass method를 이용하여 실험전, 실험3일후, 1주일, 2주일, 3주일, 4주일 후의 치태지수와 salcus bleeding index(SBI)를 측정하여 다음과 같은 결론을 얻었다.

1. 치태지수는 실험1군에 비해 실험2, 3, 4군이 실험기간이 경과함에 따라 큰 감소효과를 보였으며 실험 3, 4군간의 차이는 없었다.

2. 치태지수는 실험2, 3, 4군이 실험1군에 비해 협면보다 설면에서 많이 감소했다.

3. SBI는 모든 실험군에서 감소 현상을 보였다.

4. SBI의 감소는 모든 실험군에서 협면과 설면사이의 차이는 없었다.

5. 실험 2, 3, 4군에서 치태지수의 감소는 SBI의 감소와 관계가 있었다.

이상의 결과를 통해 볼 때 보조기구를 병행함으로써 치태감소에 유효한 결과를 얻을 수 있다고 사료된다.

(Directed by Assistant Prof. Jung Kiu Chai, D.D.S., M.S.D., Ph.D.)

The purpose of this study was to compare the effectiveness of the various

mechanical plaque control methods, brushing(Exp. 1 group), brushing + water

pick(Exp. 2 group), brushing + tooth pick(Exp. 3 group), brushing + dental

floss(Exp. 4 group) on the plaque accumulation and gingival inflammation. 30

volunteers were selected for this study from the dental students, after 3 days 1,

2, 3, 4 weeks experimental periods, the plaque index and sulcus bleeding index were

recorded.

The obtained results were as follow.

1. In plaque index. Exp. 2, 3 and 4 group were more effectiveness of plaque

reduction that Exp. 1 group, no difference between Exp. 3 and Exp. 4 group.

2. On lingual surface, there was more reduction of the plaque index in the Exp.

2, 3, 4 group than Exp. 1 group.

3. In sulcus bleeding index, there was reduction in all experimental group.

4. There was no significantly difference of sulcus bleeding index between buccal

and lingual surface.

5. There was correlation between the reduction of plaque index and sulcus

bleeding index in Exp. 2, 3, 4 group.
