Abstract
This paper reveals the antibody titer of plaque microorganisms in experimental gingivitis rats of differents ages and immunization. Before sacrificing expermental animals status of gingival tissue was assessed. Further on speciments of saliva and serum were taken for antibody titer measurements. None of the young rats developed gingivitis during experiment, where as the adult immunized rats bled on probing. Low values of antibodys point out the abesnce of intensive synthesis of specific antibodys in saliva upon the antigen stimulation of plaque maicroorganisms. Serum antibody titers were low in young rats, moderate in adult, and high in adult immunized rats. These results indicate that adult rats react stronger to plaque antigents than young rats and that praevious contact with the antigens increases the reaction.
