[The in vitro study on Polistes mandarinus' effects on cariogenic bacteria].
OBJECTIVE
To study the role of Polistes mandarinus on the growth,acid generation and water insoluble glucan(WIG) production of Streptococcus mutans, Streptococcus sanguis and Actinomyces viscosus as a preparation for screening an effective agent ot medicate the balance of oral microflora.


METHODS
Streptococcus mutans 3a3, Streptococcus sanguis SB 179 and Actinomyces viscosus ATCC 19246 were chosen as the experimental bacteria. The effects of Polistes mandarinus on the growth, acid generation and glucan production were observed.


RESULTS
Polistes mandarinus can inhibit the growth and acid generation of S.mutans,S.sanguis and A.viscosus, and the water-insoluble glucan production of S.mutants and S.sanguis effectively.


CONCLUSIONS
Polistes mandarinus can inhibit the growth, acid generation and glucan production of oral bacteria effectively.
