ABSTRACT

2012년 상반기 건강보험주요통계에서 모든 연령대의 다빈도 상위 5위를 차지한 질환이 호흡기계 및 치과 질환으로, 치아 우식증을 연령대별로 보면 아동기 만 7-12세에서 5위를, 청소년기 만 13-18세에서는 3위를 차지했다(Ministry of Health and Welfare [MOHW], 2012). 또한 만 12세 우식 경험 영구치 지수는 OECD의 세계평균 1.6개에 비해 우리나라는 2000년 3.3개, 2006년 2.2개, 2010년에는 2.1개로(MOHW, 2010) 외국의 선진국과 비교했을 때 우리나라 어린이가 높게 나타났고, 2000년 조사부터 감소 추세를 보였으나, 감소의 폭이 최근 정체되는 양상을 보이고 있어 지속적인 예방사업을 시행하고 강화시켜야만 선진국 수준에 도달할 수 있을 것으로 예측할 수 있다(MOHW, 2012).

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.
