| Research Abstract |
Dental caries is the result of a bacterial infection which triggers the hutnoral immune response of antibody production. These antibody react with bacterial antigens within the carious lesion. We have sought to identify the immunoglobulins in human dentinal caries, and to determine their class, their capacity for penetrating into carious lesions. The immunoglobulin associated with advanced human dentinal caries may be pupal in origin, as it was mostly located between the pulp and the carious lesion of the vital teeth. The most frequent deposits were of IgG followed by IgA and IgM. sIgA was most frequently found in plaque, but was also present in the soft part of the lesions.
