Abstract

This study aims to measure oral health knowledge and practice level among dental clinic patients, and examine their relationships with decayed, missing and filled teeth (DMF) index and the oral health-related quality of life (QOL). Empirical data have been collected from 311 patients through structured questionnaires and dental examinations conducted in Busan area. According to the analysis of causal relationship, oral health knowledge turned out to have a direct effect on oral health practices, which exerted both direct and indirect effects on DMF index and oral health-related QOL. While DMF index directly affected the oral health-related QOL, oral health knowledge proved to have only an indirect effect on DMF index and oral health-related QOL, mediated by oral health practices. Considering all these findings, effective oral health education and other intervention programs should focus on motivating people to participate in the active practices of desirable oral health behaviors, which will lead to the prevention of oral diseases and the subsequent improvement in the QOL.

삶의 질에 대한 관심이 증가함에 따라 건강과 관련된 삶의 질 향상에 대한 관심도 증가하고 있다. 구강건강의 관점에서도 구강질환이 삶의 질을 저하시키며, 구강질환의 예방이 삶의 질을 향상시킨다. 본 연구에서는 구강보건지식과 구강보건실천 정도, 구강건강상태, 그리고 구강건강 관련 삶의 질의 관계를 알아보고자 하였다. 부산지역에 소재한 종합병원 치과, 치과병원 및 치과의원에 내원한 환자 311명을 대상으로 2010년 3월 16일부터 한달간 구조화된 자기기입식 설문지를 사용하여 대상자의 일반적 특징 및 구강보건지식, 구강보건실천, 구강건강관련 삶의 질(OHIP-14) 등에 대한 자료를 수집하였으며, 치과의사 11명이 치경과 탐침으로 사랑니를 제외한 28개의 치아를 대상으로 우식경험치아수(DMF index)를 확인하였다. 분석결과, 구강보건지식은 구강보건실천에, 구강보건실천은 우식경험치아수와 구강건강관련 삶의 질에 직접적인 영향을 미치는 것으로 나타났고, 우식경험치아수도 구강건강관련 삶의 질에 유의한 변수임을 알 수 있었다. 그러나 구강보건지식은 우식경험치아수와 구강건강관련 삶의 질에 직접적인 영향요인이 아니라, 구강보건실천의 매개를 통해 간접적으로 영향을 미치는 것으로 나타났다. 이러한 연구결과는 구강건강관련 삶의 질을 높이기 위해서는 직접적인 효과를 가지고 있는 구강보건실천 수준과 우식경험영구치아수를 적절히 관리할 수 있도록 하는 방안마련이 절실히 요구됨을 말해주고 있다. 즉 우식경험치아수는 구강보건실천에 직접적으로 영향을 받는 변수이므로 단순히 구강건강관련 지식만을 전달하기보다는 태도의 변화와 실천 행동을 유도할 수 있는 구강보건교육 프로그램을 개발함으로써 구강질환의 예방과 조기치료로 이어지도록 해야 할 것이다.
