– Mouthrinsing with SnF 2 reduced the Streptococcus mutans population in plaque and saliva and the proportion of Streptococcus sanguis in plaque. The effect was of short duration: 2 weeks after treatment the values of S. mutans in plaque and saliva were even higher than the pretreatment values. Topical SnF 2 applications reduced the S. mutans population in plaque and saliva but did not reduce the proportion of S. sanguis in plaque. The eflect was more prolonged: 4 weeks after treatment the S. mutans population in interproximal plaque remained significantly reduced and the salivary levels of the organism had not fully returned to pretreatment levels. Both SnF 2 treatments significantly increased the salivary levels of lactobacilli. The values of laclobacilli in saliva remained signilicantly increased 4 weeks after the SnF 2 mouthrinsing but had almost returned to pretreatment levels within 2 weeks after the topical SnF 2 applications. The findings suggest that the cariogenic potential of dental plaque is differently affected depending on whether a drug is administered as a mouthrinse or is applied topically.
