Claims8
A method of preventing the formation or aggravation of dental plaque consisting essentially of the step of contacting a tooth surface of a patient with at least one tea polyphenol selected from the group consisting of epicatechin gallate, gallocatechin gallate, epigallocatechin gallate, free theaflavin, theaflavin monogallate A, theaflavin monogallante B and theaflavin digallate, said tea polyphenol being in a concentration effective to inhibit the formation and adherence on said tooth surface, of a water insoluble glucan formed by Streptococcus mutans glucosyltransferase.
A method for reducing cariogenesis consisting essentially of the step of contacting a tooth surface of a patient with at least one teas polyphenol selected from the group consisting of epicatechin gallate, gallocatechin gallate, epigallocatechin gallate, free theaflavin, theaflavin monogallate A, theaflavin monogallate B and theaflavin digallate, said tea polyphenol being in a concentration effective to inhibit the formation and adherence on said tooth surface, of a water insoluble glucan formed by Streptococcus mutans glucosyltransferase.
