Effect of Tea Polyphenol on Pathogenetic Bacteria in Oral and Pharynx in Vitro

Objective In order to evaluate the possibility of Tea polyphenol as a new drug to prevent caries, periodontitis and pharyngitis. Methods The effects of tea polyphenol on the growth of bacteria, which was known as pathogenesis of caries,periodontitis and pharyngitis, and on the polysaccharide synthesis of cariogenic bacteria as well as salivary amylase activity of host, were determined. Results Polyphenol could inhibit the bacteria growth, polysaccharide synthesis and amylase activity. Conclusion It will probably be a relatively ideal natural agent that both decreases incidence of caries, periodontitis and pharyngitis and maintatins the balance of oral ecology system.
