Protective effect of oral Lactobacilli in pathogenesis of chronic periodontitis.

Abstract

development of CP is linked to persistent excessive cytokine response of Th17 cells, the intensity of which may affect clinical course of the disease; in parallel, H(2)O(2)-producing oral lactobacilli may prevent against progression of CP, most probably reducing secretory activity of Th17 cells and restricting growth of periodontopathogens.
