Abstract

In 2011, South Korea's Ministry of Health and Welfare started a national tooth brushing room program without a pilot project. This study aimed to assess the effect of the implementation of this program in Gangneung, Korea. One-year outcomes of oral health behavior and self-reported oral symptoms in the study group after installation of the tooth brushing room were evaluated and compared with those of the control group using chi-square test. The prevalence rate of good self-rated oral health in grade 1-3 students increased from 35.7% immediately after installation to 48.9% after 6 months (p=0.031) compared to 37.3% in the control group (p=0.051). Immediately after installation of the tooth brushing room, 53.5% of grade 1-3 students in the study group brushed their teeth every day, but after 6 months, only 35.5% of students brushed daily (p<0.001) compared to 28.6% in the control group (p=0.007). The prevalence rate of bad breath in grade 1-3 students was 26.2% for the study group immediately after installation compared to 25.5% in the control group (p=0.065), but it declined 16.5% after 6 months (p=0.055). The prevalence rate of bad breath in grade 4~6 students was 14.7% for the study group after 6 months compared to 25.3% in the control group (p=0.016). We recommend the creation of a healthy school environment through a school-based tooth brushing program under the active supervision of classroom teachers and the continuous monitoring of program processes in order to promote children's oral health.

본 연구에서는 초등학교 양치교실사업의 효과를 평가하고 추후 효과적인 사업 운영을 위한 개선방안 마련의 기초자료로 활용하고자, 2011년에 양치교실을 설치하여 운영 중인 강릉시 P초등학교 학생을 대상으로 양치교실 설치 후 구강건강행태 및 구강증상경험 수준의 변화를 확인하였다. 1. 모든 군에서 칫솔질 및 식습관에 대한 구강건강지식 문항의 정답률과 구강건강에 대한 바른 인식률은 낮은 수준이었고, 실험군 저학년의 자신의 구강건강수준을 매우 건강 또는 건강하다고 생각하는 비율은 양치교실 설치 직후 35.7%에서 6개월 후 48.9%로 증가하였다(p=0.031). 2. 학교에서 점심식사 후 매일 칫솔질 실천율은 실험군 저학년에서는 1차 조사 시 53.5%에서 6개월 후 2차 조사 시 35.5%로 18.0% 감소하였고, 6개월 후 3차 조사 시에는 비슷한 수준(35.4%)으로 유지되었으며(p<0.001), 고학년에서는 2차 조사(42.1%)에 비해 3차 조사(35.1%) 시 소폭 감소하였다(p<0.001). 대조군의 매일 칫솔질 실천율은 실험군 3차조사 결과와 비교하였을 때 저학년 28.6%, 고학년 6.0%로 통계적으로 유의한 차이가 나타났다(p=0.007, p<0.001). 3. 실험군과 대조군에서 점심식사 후 매일 칫솔질하지 않는 이유로 이 닦는 것을 깜빡 잊어버렸기 때문으로 응답한 비율이 가장 높게 나타났다. 4. 구강증상경험률은 실험군 고학년의 치통경험을 제외한 모든 증상에서 1차 조사에 비해 6개월 후 2차 조사 시 경험률이 소폭 감소하였으나 통계적으로 유의하지 않았고, 고학년의 입냄새 경험률은 2차 조사 시 실험군 14.7%에 비해 대조군 25.3%로 통계적으로 유의하게 높았다(p=0.016). 5. 실험군에서 양치교실을 이용할 때 대부분 보건 선생님이 지도해 주는 것으로 나타났고, 양치교실 이용 시 불편한 점으로 양치교실의 위치가 멀리 떨어져 있는 것과 양치교실이 좁아서 복잡하거나 혼잡하다고 응답하였다. 이상의 결과로 볼 때 양치교실 설치사업을 통한 환경 개선의 효과를 지속적으로 유지하기 위해서는 학생의 적극적인 참여, 선생님의 관리감독 강화, 지역사회 협력체계 구축 등을 통한 지속적인 모니터링이 이루어져야 하며, 구강보건교육 및 양치교실 설치사업이 다양한 건강증진전략과 통합하여 운영될 때 지역사회 아동 청소년 건강증진을 위한 통합건강증진사업으로도 확대될 수 있을 것으로 기대할 수 있겠다.
