Although fluoride has been widely used for caries prevention in various ways, attention is now being paid to the use of toothpaste containing fluoride for caries control.<BR>The inhibition of decalcification and the remineralization of initial carious lesions should be promoted by the continuous presence of fluoride derived from toothpaste in dental plaque and saliva.<BR>In this study, I assessed the effects of toothpaste containing 100 or 250 ppmF- as NaF on the fluoride level in the oral environment, on selected organic acids in plaque, and on the number of bacteria in plaque.<BR>The results obtained were as follows:<BR>1) Fluoride concentration in both plaque and saliva was increased significantly by the use of fluoride-containing toothpastes (p<0.05).<BR>2) With 250 ppmF- toothpaste the fluoride concentration in plaque and saliva was higher than that obtained when 100 ppmF- tooth paste was used. However, these levels decreased to almost the original levels after 60 minutes. Therefore, the oral clearance of fluoride is apparently rapid.<BR>3) Acid production in plaque was inhibited significantly by the use of fluoride-containing toothpastes (p<0.001).<BR>4) When the 250ppmF- toothpaste was used for 5 days, the bacterial number in plaque tended to decrease.<BR>5) These data suggest that fluoride-containing toothpaste could prevent caries incidence even at a concentration as low as 100 or 250 ppmF-.
