Study Notes
Bacteria associated with Caries
- Caries are caused by bacteria that form plaque on the teeth
- Streptococcus mutans is one of the primary bacteria associated with dental caries
- Streptococcus mutans was first found in carious lesions by Clarke in 1924
- Streptococcus mutans is a member of the Mutans Streptococci (MS) group, and is often associated with dental caries in rodents
- Other organisms in the MS group include S. sobrinus, S. rattus, and S. cristatus
- Dental caries is an infectious disease that can be spread between individuals
Evidence Implicating Streptococcus mutans in Caries
- High quantities of Streptococcus mutans are found in carious lesions
- People with more active caries have higher levels of Streptococcus mutans, greater than 10^6/ml of saliva, than those without active caries
