title: Antibodies against Streptococcus mutans and glucosyltransferases in caries-free and caries-active military recruits.
abstract: 1) Plaque samples from caries-active recruits showed a higher incidence of S. mutans than plaque samples from caries-free recruits. The persistance of the S. mutans serotypes in the individual plaque samples attested to the consistency of S. mutans in human dental plaque. 2) S. mutans serotype d is predominantly present in approximal plaque of caries-active subjects. 3) Serum antibody titers against S. mutans are higher in caries-active individuals. 4) Sera from caries-free or caries-active individuals inhibit the insoluble glucan synthesis by the cellbound GTF to the same extent. 5) It is unlikely that antibodies against S. mutans in parotid saliva or serum play a major role in the protection against dental caries in Dutch military recruits.
