The article presents the results of treatment of 157 patients with generalized periodontitis depending on blood type. In the blood of patients with generalized periodontitis was determined: the number of erythrocytes, the number of leukocytes, platelets, neutrophils, leukocyte intoxication index, fibrinogen. After treatment, analysis of blood cell composition showed that 1 year after treatment of generalized periodontitis, carriers of 0 (I) and A (II) blood type increased the number of erythrocytes in the blood – 1.2 times. At the same time, a decrease in the number of leukocytes on average was determined by 1.4 times, and leukocyte intoxication index values – by 2.0 times in representatives of 0 (I) and B (III) blood type; neutrophils – 1.4 times in people with A (II) blood type; platelets – 1.3 times in carriers with 0 (I) and AB (IV) blood type, according to data before treatment. The improvement of hematological and hemostasiological indicators of blood in patients with generalized periodontitis indicates a positive effect on the organs and systems the medicines we have prescribed, the positive effect of which is reflected, in particular, on the complex of tooth-retaining tissues.

The article presents the results of treatment of 157 patients with generalized periodontitis depending on blood type using polypeptide drugs. The concentration of total protein, C – reactive protein, IgG, TRACP, BSALP, albumin, amylase, lipase, Ca, Fe was determined in the oral fluid. The treatment allowed to reduce the content of total protein, C – reactive protein, TRACP in the oral fluid with increasing levels of calcium, Fe, BSALP, in relation to the relevant data before treatment. And also, polypeptide drugs helped to increase the level of albumin in representatives of 0 (I) and A (II) blood type in the oral fluid; contributed to a decrease: glucose, IgG with increasing activity, amylase and lipase in carriers of B (III) and AB (IV) blood type in the oral fluid, in relation to the values before treatment. The dynamics of indicators of oral fluid metabolism with the help of polypeptide drugs, convincingly proves the effectiveness of their use in the treatment of generalized periodontitis in patients with different blood type.
