Abstract

This study aimed to evaluate the effects of national dental screening for children in Korea in the aspects of prevention of dental caries, the number of treatments related to dental caries, and cost of dental care. The study used the national cohort data on children health screening provided by National Health Insurance Service, and analyzed 32,937 1st dental screening, 22,608 2nd dental screening, 13,708 3rd dental screening, and 241,043 cases from the dental care of 27,944 children born in year 2008 and 2009. The decayed-filled teeth index and decayed-filled person rate, calculated from the results of the 2nd and 3rd dental screening, decreased as the number of preceding dental screening increased. Glass ionomer and amalgam restoration, pulp treatment of primary teeth and extraction of primary canine and molar were shown to decrease as the number of examined dental screening increased, and the total cost of dental care covered by national health insurance also decreased as the number of dental screening increased. In conclusion, national dental screening for children is an efficient and economical oral health care method that prevents dental caries and lowers the possibility of dental caries related treatment, thereby reducing cost of dental care.

이 연구의 목적은 영유아구강검진의 효과를 치아우식 예방, 우식 치료행위, 치과진료비용이라는 다각적 관점에서 분석, 평가하는 것이다. 국민건강보험공단에서 제공하는 영유아검진코호트 데이터베이스를 활용하였고, 2008 - 2015년에 시행된 구강검진 1차 32,937건, 2차 22,608건, 3차 13,708건 및 2008년생과 2009년생 27,944명의 치과 진료 241,043건을 분석하였다. 2차와 3차 구강검진 결과를 통해 산출한 우식경험유치지수와 유치우식경험자율은 각각의 선행 구강검진 수검 횟수가 증가함에 따라 감소하였다. 유치의 급여 수복치료 및 치수치료, 유견치와 유구치의 조기 발치 시행 횟수는 구강검진 수검 횟수가 증가함에 따라 감소하였고, 전체 급여 치과진료비용 또한 수검 횟수가 증가함에 따라 감소하였다. 영유아구강검진은 치아우식을 예방하여 치아우식 관련 치료의 가능성을 줄이고, 따라서 치과진료비를 절감하는 효율적이고 경제적인 구강 건강 관리 방법이다.
