[Use of immunotherapy with bacterial allergens in the combined treatment of periodontitis].

Bacterial allergens were used in the treatment of patients with chronic generalized slight and medium severe periodontitis. The allergens were used for hyposensitization or immunostimulation, depending on skin reactions to staphylococcal, streptococcal, and Escherichia coli allergens. Positive shifts in nonspecific immunity were attained; bacterial sensitization decreased, which indicates the treatment efficiency.
