Abstract
Non-cariogenic composition, which comprises as active ingredient the living cells of a Human type strain of Streptococcus mutans capable of inhibiting the growth of cariogenic strains of S. mutans and incapable of inducing dental caries, in association with a carrier or excipient suitable for oral administration, said strains of S. mutans being isolated from the oral cavity of humans as naturally-occuring strains. The non-cariogenic composition may be administered orally in the form of liquid, semi-solid or solid compositions, preferably in the form of yogurts containing edible lactic acid-producing bacilli or in the form of a freeze-dried composition containing such edible lactic acid-producing bacilli. The non-cariogenic composition may prevent or at least inhibit human dental caries induced by cariogenic S. mutans and moreover effective against other cariogenic oral bacilli such as edible lactic acid-producing bacilli known per se. Direct administration to human oral cavity may be effected simply and safely since the used effctor strains are naturally-occuring strains in the oral cavity of humans.
