Fluoride dentifrice has been accepted widely for use in caries prevention and its effectiveness has been confirmed. In order to enable the use of fluoride dentifrice effectively in daily brushing, the present study was performed to examine the relationship between fluoride uptake and the amount of fluoride dentifrice used and brushing time for adults. We examined the relationship between fluoride uptake into the surface layer (4-6 μm)of enamel and the active fluoride concentration in vitro and the relationship between the amount of fluoride dentifrice (1,000ppmF) used and the fluoride concentration in oral fluid in vivo. It became clear that fluoride uptake into the enamel was increased at the concentrations of 300ppmF or more. Fluoride uptake at 300ppmF was increased for 2min and became saturated thereafter. The results of the relationship between the fluoride concentration in the oral fluid and the amount of fluoride dentifrice used indicated that the amount of dentifrice that could maintain the mean fluoride concentration at 300ppm or more for 2min was 1.0g or more. From these results, the recommended amount of fluoride dentifrice (1,000ppmF) is 1.0g or more for adults.

@kodoare こちらこそ重要な点をご質問頂き有難う御座いました。効果の部分をもう少し細かくすると、エナメル質に対してフッ化物は300ppm以上あると効果的とされていて、この点から成人では1g以上で2分間の歯磨きが推奨されていたりします。ご質問有難う御座いました!https://t.co/PEb6PcqJL3
