你一定每天用牙刷来清洁牙齿,但你不一定知道保持牙刷清洁的重要性。美国俄克拉荷马大学牙科学院的专家们曾对人们用过的牙刷进行检测,通过细菌培养发现很多牙刷上沾有白色念珠菌、溶血性链球菌、肺炎杆菌和葡萄球菌等。这样,牙刷就成了一些疾病的传染源——刷牙时,细菌通过人们的直接吞咽或破损的牙龈粘膜和口腔粘膜侵入人体,引起牙龈炎、慢性咽炎、口腔炎以及肠炎、脓毒血症、败血症、风湿性心肌炎和肾炎等。
You must clean your teeth with a toothbrush everyday, but you do not necessarily know the importance of keeping your toothbrush clean. Experts from the University of Oklahoma University School of Dentistry once tested toothbrushes that people used and found that many toothbrushes were stained with Candida albicans, hemolytic streptococcus, Klebsiella pneumoniae and staphylococcus. In this way, the toothbrush has become the source of some diseases - when brushing, the bacteria invade the human body through the gums and oral mucosa directly swallowed or damaged by people, causing gingivitis, chronic pharyngitis, stomatitis and enteritis, sepsis, Sepsis, rheumatic myocarditis and nephritis.
