RESUMO
OBJECTIVE: The aim: Analysis of literary sources with the study of modern views on the problem of the immune status of the oral mucosa. PATIENTS AND METHODS: Materials and methods: The review and analysis of scientific and medical literature for the years 2013-2019, based on Scopus databases, Web of Science, Med Line, The Cochrane Library, EMBASE, Global Health, CyberLeninka, RIC. CONCLUSION: Conclusions: Bacterial wall antigens are able to affect the local immune response of the oral mucosa. In particular, suppression of lymphocytes and macrophages proliferation, alteration of adhesion molecules expression and homing of the immune system cells to the inflammation site, inhibition of cytokine secretion by contact of the immune system cells with gram-positive bacteria is revealed. Therefore, studying the changes in the differentiation of the oral mucosa epithelium and periodontal tissues under the influence of environmental factors is of relevance. The conception of the oral cavity as a complex ecological system has not only theoretical but also practical value. Summarizing the data, we can say that at the current stage of science development the interaction of all structures should be considered, focusing on epitheliocytes of the oral mucosa, as a closing chain, which initiates changes that can affect the condition of the oral cavity and the results of pathological processes treatment of the oral cavity mucous membrane and periodontal tissues.
