초록

본 연구는 어린이집에서 유아들이 사용하고 있는 칫솔의 칫솔마모 상태를 평가하여, 유아의 칫솔 교체시기에 대한 적절한 기준을 확립하는 데 도움을 주고자 2012년 9월 20일부터 11월 6일까지 1,022개의 칫솔을 수거한 뒤 칫솔마모도 및 마모율을 평가하여 다음과 같은 결과를 얻었다. 1. 칫솔마모도 측정 결과, 조사 대상 칫솔 중 48.5%가 0.400 이상의 마모도를 보였고, 평균 마모도는 $0.421{\pm}0.239$로 조사되어, 전체적으로 높은 칫솔마모도를 보였다. 2. 칫솔마모율 측정 결과, 마모율 2점과 3점이 차지하는 비율이 70.4%였으며, 평균 마모율은 $1.936{\pm}0.848$로 나타나 전체적으로 높은 칫솔마모율을 보였다. 3. 칫솔관리 실태에 대한 조사 결과, 평균 칫솔 교환주기는 5~8주가 63.9%로 가장 많았고, 칫솔 교환방법은 칫솔모의 마모 상태에 따라 교체한다는 응답이 52.7%로 조사되었다. 이상의 결과를 바탕으로, 유아들의 칫솔에 대한 관리가 적절히 이루어질 수 있도록 보육을 담당하는 교사 및 보호자에 대한 지도가 필요할 것이며, 유아의 올바른 칫솔 교체주기에 대한 명확한 기준 확립과 효율적인 구강보건교육 방안도 마련되어야 할 것이다.

The purpose of this study was to examine the toothbrush bristles' wear index and wear rate used by preschool children to provide information on the establishment of criteria for toothbrush replacement cycle for preschool children. One thousand twenty-two toothbrushes were collected from September 20 to November 16, 2012 was analyzed. The findings of the study were as follows: 1. As a result of analyzing the toothbrush wear index, 48.5% of the collected toothbrushes was above 0.400, and the average wear index was $0.421{\pm}0.239$. 2. As a result of analyzing the wear rate of the toothbrushes, score 2 and 3 accounted for 70.4%, and the average wear rate stood at $1.936{\pm}0.848$. 3. As a result of analyzing the state of toothbrush management, the most common average toothbrush replacement cycle was one or two months (63.9%). Concerning the method of toothbrush replacement, the largest group (52.7%) replied they changed toothbrushes based on the abrasivity of toothbrush bristles, and 16.7 percent did that at the request of parents. Given the above-mentioned findings of the study, preschool teachers and parents should be educated to ensure the successful management of preschool children toothbrushes. In addition, it's required to set evident criteria for the right toothbrush replacement cycle for preschool children, and how to provide oral health education in an efficient way should be considered as well.
