Abstract
The oral bacteria Actinomyces naeslundii andActinomyces viscosus are known to contribute to the initiation and progression of human dental caries, especially root caries. We report that both A. naeslundii and A. viscosus react with a component in the Gardenia jasminoides extract to produce a distinct green product. This green color reaction was found to be dependent on the bacterial β-glucosidase. The reaction is specific for cariogenic actinomyces, and it can detect as few as 104 cells of A. naeslundii and A. viscosus per ml.Keywords
