OBJECTIVE The aim: To analyze the state of periodontal tissues against the background of Helicobacter pylori invasion in dynamics and to propose a possible mechanism of development of inflammatory periodontal diseases in patients with Helicobacter pylori-associated pathology of the gastrointestinal tract. PATIENTS AND METHODS Materials and methods: We examined 43 patients with Helicobacter pylori-associated gastrointestinal pathology and 42 patients of the same age without somatic pathology, including without gastrointestinal pathology associated with Helicobacter pylori. Clinical and laboratory research methods (clinical, instru-mental, biochemical, histological methods) were used. RESULTS Results: Comparing the data of clinical observations and the results of laboratory studies of patients with inflammatory periodontal disease on the background of Helicobacter pylori-associated gastrointestinal pathology, obtained in different observation periods, we can assume that basic dental treatment of periodontal disease in such patients undergoing eradication therapy does not provide stable anti-inflammatory, antimicrobial and antioxidant effect, which leads to reduced periods of remission and recurrence of periodontal disease, where oral dysbiosis plays a crucial role. CONCLUSION Conclusions: Comparing the data of clinical observations and the results of laboratory studies of patients with chronic gingivitis on the background of Helicobacter pylori-associated gastrointestinal pathology, obtained in different observation periods, we can say that they correlate with each other and suggest that the basic dental treatment of chronic gingivatis on the background of H.pylori-associated pathology of the gastrointestinal tract, which is currently undergoing a course of eradication, does not give a stable anti-inflammatory, antimicrobial and antioxidant effect, which leads to recurrence of periodontal disease and shortening remission periods, where oral dysbiosis plays a crucial role.
