일부 어린이집 유아의 칫솔 마모도 및 마모율 평가 = Evaluation of Toothbrush Bristles` Wear Index and Wear Rate Used by Preschool Children

국문 초록 (Abstract)

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±0.239로 조사되어, 전체적으로 높은 칫솔마모도를 보였다. 2. 칫솔마모율 측정 결과, 마모율 2점과 3점이 차지하는 비율이 70.4%였으며, 평균 마모율은 1.936±0.848로 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 교체 주기에 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±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±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.
