Abstract

Objective of this study was to compared the amount of bacteria in the toothbrush according to the management method of the toothbrush in use and the acidity of intraoral bacteria. Toothbrushes in use in more than one month of 50 healthy adults were collected and the number of bacteria and pH of the toothbrushes were measured. When the number of brushings per day was 4, the pH 4.97 and the microbial numbers was the lowest at 42.16(104×CFU/ml). When the replacement period of the toothbrush was 1 month, the pH 5.35 and the microbial numbers was the lowest at 19.80(104×CFU/ml). When stored in the bathroom, the pH 4.78, and the microbial numbers was highest at 149.46(104×CFU/ml). As a result, in order to block the germs of the toothbrush, it is necessary to develop a method that can easily disinfect the contaminated toothbrush at home. In addition, I think that it is necessary to educate about the proper brush cleaning and storage method when teaching brushing.

본 연구는 사용 중인 칫솔의 관리법과 구강내 세균의 산생성도에 따른 칫솔의 세균량을 측정하여 비교한 후 올바른 칫솔 관리를 위한 교육자료를 개발하는데 기초자료로 제시하고자 한다. 건강한 20대 성인 50명의 1개월이상 사용 중인 칫솔을 수거하여 칫솔의 세균수와 pH를 측정하였다. 하루 칫솔질의 횟수가 4회인 경우 pH는 4.97로 가장 높았고 세균수는 42.16(104×CFU/ml)으로 가장 낮게 나타났으며 칫솔의 사용 교체 시기가 1개월인 경우 pH가 5.35로 가장 높았고 세균수는 19.80(104 × CFU/ml)로 가장 낮게 나타났다. 욕실에 보관한 경우 pH는 4.78로 가장 낮았고 세균수는 149.46(104 × CFU/ml) 가장 높게 나타났으며 유의한 차이가 있었다(p<0.01). 연구결과 칫솔의 세균을 차단하기 위해서는 가정에서 오염된 칫솔을 간단하게 살균할 수 있는 방법을 연구하고 개발해야 할 것이다. 또한 칫솔질 교육을 할 때 올바른 칫솔 세척 방법과 보관법에 대하여 교육을 할 필요가 있다고 생각된다.
