| Research Abstract |
This study was carried out to develop a method to estimate the bacterial ecology for oral biofilm, by mapping the quantitative distribution of glucan, biomass and oral streptococci from the outermost to the innermost layers of oral biofilm, indicating the effect of fluorides and sugars on the bacterial ecology. This study also revealed that a single mouthrinse with 250ppm fluoride solution could inhibit the acidogenicity of the oral biofilm in vivo and that the irrigation using a dental water jet would be an effective means of biofilm control, by measuring the thickness of the biofilm.
