In order to find a connection between the alteration of oral tissues and genetic predisposition to inflammatory and destructive processes in oral media, the cytokine profile of the oral fluid of clinically healthy individuals was determined for various blood group affiliations according to the AB0 system. The group-specific features of individuals with B(III) blood group were revealed: an increase of 32,5% in the content of interleukin-6 and 63,1% in the content of interleukin-8 compared with similar data for people with 0(I), A(II), AB(IV) blood groups, which can predispose to the greatest activity of the inflammatory process in the oral cavity in individuals with antigen B. Confirmation of this fact is an increase of IgA antibodies to gliadin in the blood among patients with chronic generalized periodontitis with B(III) blood group, up to 5,00 U/ml (p<0,01), which indicates the processes of acute inflammation, and along with an increase in blood IgG antibodies to transglutaminase in comparison with a group of clinically healthy individuals, it serves as an indicator of damage to the body's connective tissue at the molecular level. When examining the dental status, pronounced clinical manifestations of chronic generalized periodontitis were found in patients with A(II) blood group, the molecular foundation of which is the highest content of IgA and IgG antibodies to transglutaminase in the oral fluid (0,35 U/ml and 0,45 U/ml), which contributes to the activation of periodontal-destroying inflammatory and inflammatory processes, obviously, with a tendency to the chronic course of the disease. The studies performed allowed us to analyze in clinically healthy individuals a predisposition to alternative processes in oral environments, using gradation by group blood affiliation.
