【摘要】 9名受试者采用正放及倒放方式使用漱口杯各14 d,检测2种摆放方式下漱口杯中口腔及胃肠道条件致病菌滞留情况。结果显示大肠菌群、变异链球菌、念珠菌计数对数值(CFU/ml)分别为4.25±0.71 vs 2.84±1.40(P=0.046)、89±0.31 vs 2.84±1.40(P<0.001)、2.28±1.36 vs 2.53±1.92(P=0.002),正放组检测出霉菌(2.44±0.99)CFU/ml,倒放组未检出。倒放漱口杯更加合理、利于健康。更多还原

【Abstract】 The oral and gastrointestinal opportunistic pathogen contamination was compared between tooth mugs placed upward and downward( n = 9) for 14 days. Selective cultivation of the pathogens was uesd to measure the extent of contamination. The colony forming units( CFU) of colibacillus in group up and group down were 4. 25 ± 0. 71 and 2. 84 ± 1. 40( P = 0. 046),S. mutans 89 ± 0. 31 and 2. 84 ± 1. 40( P < 0. 001),Candida 2. 28 ± 1. 36 and 2. 53 ± 1. 92( P = 0. 002),fungus 2. 44 ± 0. 99 and 0,respecitvely. Thus,tooth mug placed opening down is superior for health.更多还原
