Comparison of oral and gastrointestinal opportunistic pathogen contamination between tooth mugs placed up-ward and downward / 实用口腔医学杂志

The oral and gastrointestinal opportunistic pathogen contamination was compared between tooth mugs placed upward and down-ward(n=9)for 1 4 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 open-ing down is superior for health.
