ABSTRACT
Risk factors for severe COVID-19 are also associated with periodontitis. They are smoking, older age, obesity, diabetes mellitus, hypertension and cardiovascular diseases. The aim of the study was to select and analyze publications that consider a possible relationship between inflammatory periodontal diseases and the severity of COVID-19. Material and methods. The search for publications by the key words was conducted using the electronic databases: Cochrane Library;MEDLINE, eLIBRARY for systematic review. We selected 94 publications, the systematic review included 10 scientific articles presenting the results of randomized trials. Results. The results of the analysis showed the connection between COVID-19 severity and inflammatory periodontal diseases presence. In the patients with severe COVID-19 on the background of periodontitis it was established a high risk for artificial lung ventilation prescription. The course of COVID-19 is possibly depending on high expression of ACE2 receptors in oral mucosal cells and aspiration of pathogenic bacteria from periodontal tissues with saliva on the background of SARS-CoV-2 viral infection. The bacterial etiology of periodontitis plays important role of an immunological trigger that causes hyperreaction of humoral and cellular immunity, NETosis activation and NLRP3 inflammation. Conclusion. The presence of periodontitis in patients with overweight and obesity, DM or hypertension may be associated with severe COVID-19 course, possible development of complications and pneumonia.Copyright © Eco-Vector, 2023.
