치간 칫솔 교육이 초등학생의 치면 세균막 지수와 구취 정도에 미치는 효과

Abstract

Purpose: This study determined the effect of inter dental brush education on the dental plaque index, and the degree of halitosis for elementary school students. Methods: The study was performed on a non-equivalent control group, with a pre-test and post-test design. The study was intended for a total of 50 students. They were divided into two groups; an experimental group of 25 students and a control group of 25 students. The experimental group participated in inter dental brush education. The education took about 20 minutes, and was provided once a week, for a total of three weeks. To quantify the effect, the two groups were compared in terms of the dental plaque index and the degree of halitosis. Results: Without inter dental brush education, or a test for homogeneity, in the sense of exact equivalence of the dental plaque index and the degree of halitosis between the experimental and the control group, was supported. (p>.799, p>.876). 1) The first hypothesis, "The experimental group, who participated in inter dental brush education, would reveal a lower dental plaque indices than the control group", was supported (t=5.78, p<.001). 2) The second hypothesis, "The experimental group, who participated in inter dental brush education, would reveal a lower degrees of halitosis than the control group", was supported (t=4.49, p<.001). Conclusion: The proposed inter dental brush education is effective in improving the dental plaque index and the degree of halitosis for elementary school students.
