[The microbiological aspects of dental caries: the evaluation of a protocol for isolating Streptococcus mutans].

The role of Streptococcus mutans in the etiopathogenesis of dental caries to set up a protocol for the culture and the identification of the bacterium, in order to obtain the isolation in an heterogeneous age, sex and stomatognathic population is described. A selected culture medium for mutans, Mitis Salivarius agar enriched with Bacitracin (MSB-agar), has been used as well as biochemical method based on carbohydrates fermentation by amplified bacterial flora for the identification of the bacterial genus.
