본 연구는 유치원에 다니는 아동 총 59명을 대상으로 Q-scan을 이용한 구강보건효과를 평가하고자 하였다. 유아용 면접설문지와 Quigley & Hein index를 측정하여 다음과 같은 결과를 얻었다. 아동의 치면세균막지수는 Q-scan을 이용한 중재군에서 12% 더 유의하게 감소한 것으로 나타났다(p＜0.001). 구강보건지식은 두 집단 모두 불소에서 유의한 차이가 나타났으며(p＜0.05), 대조군에서는 치아에 나쁜 음식에 대한 정답률도 유의하게 증가하였다(p＜0.05). 구강보건태도에서 중재군은 모든 변수에서 유의한 차이가 나타났으며(p＜0.05), 대조군에서는 정기 구강검진, 칫솔질 횟수에서 유의한 차이가 나타났다(p＜0.05). 구강보건행동에서 중재군은 칫솔 잡는 법에서는 정답률이 증가하고, 알맞은 치약 짜기에서는 정답률이 감소하는 유의한 결과가 나타났으며(p＜0.05), 대조군은 모든 변수에서 유의한 차이가 나타나지 않았다. 이러한 결과를 종합해 보면 Q-scan은 구강보건교육 시 아동들의 동기 부여를 위한 적절한 도구로 활용 될 수 있을 것으로 생각된다.

The purpose of this study was to evaluate the effect of oral health education with Q-scan for preschool children. The 59 children were divided into two groups, one with Q-scan and the other with dentiform, and they were evaluated by interview questionnaire and measurement of dental plaque index using Quigley-Hein index. Using SPSS ver. 18.0 for statistical analysis, paired t-test and Independent t-test were carried out for dental plaque index change and chi-square independence test for change between before and after oral health education. The result of this study revealed that the dental plaque index of the children showed significant decrease of 12% more in the experimental group (p＜0.001). Both groups showed significant difference in knowledge about fluorine (p＜0.05) and the percentage of correct answers showed significant increase in questions about bad food for teeth (p＜0.05). In attitude toward oral health, the experimental group showed significant difference in every variable (p＜0.05), and the control group showed significant difference in regular oral examination and frequency of toothbrushing (p＜0.05). The experimental group showed significant result (p＜0.05) with increase in the percentage of correct answers for the question about how to hold a toothbrush and decrease in the percentage of correct answers for the question about how to apply toothpaste, while the control group did not show significant difference in any variable. Therefore, Q-scan as an appropriate tool for motivation, provides effective educational methods in oral health education.
