Diagnostic assays for determination of dental caries susceptibility
InactiveUS20060127961A1Cosmetic preparationsBioreactor/fermenter combinationsRoot cariesDental Caries Susceptibility
The invention overcomes the limitations of the prior art by providing rapid assays for predicting the likelihood of caries development in patients. The assays allow implementation of appropriate dental care measures during a patient visit depending on the results of the assay. The assay utilizes the finding that caries-free children and adults have significantly higher levels of naturally occurring protective salivary IgA antibody to S. mutans than caries-active subjects. The assays are carried out using patient saliva. The speed and ease of use of the assay allows dental practitioners to assess at an early stage the relative risk of future caries formation. With this information, preventive methods may be applied only to those determined to be at risk.
