Antibacterial activity of polyphenol components in oolong tea extract against Streptococcus mutans.

abstract：:Current understanding of dental caries considers this disease a demineralization of the tooth tissues due to the acid produced by sugar-fermenting microorganisms. Thus, caries is considered a diet- and pH-dependent process. We present here the first metagenomic analysis of the bacterial communities present at differen...
