Prevention of dental caries by acupuncture.

: By acupuncture stimulation (at the Chinese meridian point), the total number of oral Streptococci and the caries-pathogenic bacteria, Streptococcus mutans, in the rats were decreased. The anti-RC-20 (Streptococcus mutans) titer of the rat serum increased as the result of acupuncture stimulation. Rat caries induced by a caries induced by a caries-inducing diet (6-PWV) was reduced by acupuncture stimulation.
