Tooth decay is a serious health risk and a significant contributor to health care costs in both industrialized and developing nations. Tooth decay is the end result of a change in the balance of plaque ecology towards more acidogenic and aciduric bacterial species. Frequent and prolonged periods of low plaque pH, facilitated by the presence of fermentable simple carbohydrates drive the cycles o...

Polymers of D-fructose produced by a variety of oral bacteria are believed to function as extracellular carbohydrate reserves. Degradation of these polysaccharides in plaque following exhaustion of dietary carbohydrates is thought to contribute to the extent and duration of the acid challenge to the tooth surface and thus to the initiation and progression of dental caries. Streptococcus mutans ...

BACKGROUND One promising way of reducing caries is by using sucrose substitutes in food. rubusoside is a prototype sweet substance isolated from the leaves of the plant Rubrus suavissimus S. Lee. (Rosaceae), and is rated sweeter than sucrose. The purpose of this study was to investigate the effects of rubusoside on Streptococcus mutans growth, acidogenicity, and adherence to glass in vitro. M...

A fermented beverage of plant extract was prepared from about 50 kinds of fruits and vegetables. Natural fermentation was conducted by lactic acid bacteria (Leuconostoc spp.) and yeast (Zygosaccharomyces spp. and Pichia spp.). Eighteen kinds of oligosaccharides were isolated from this beverage, and their structures were confirmed by methylation analysis, MALDI-TOF-MS and NMR measurements. In th...
