Abstract. The molecular level of physiological processes in the context of studying the pathogenesis of diseases is the basis for their diagnosis and treatment. Thus, the features of the pathogenesis of periodontitis are the direct participation of pro-inflammatory cytokines in the development of alterative inflammation. The study of the cytokine profile is relevant for both diagnostic and therapeutic purposes, since the dynamics of indicators of inflammatory mediators reflects the degree of activity and specificity of pathological reactions present in periodontitis. The purpose of the study Study of cytokine profile indicators in experimental periodontitis. Materials and methods. In an experiment on 50 white non-linear rats weighing 190-280 g, the model of experimental periodontitis proposed by Shkolnaya K.D., Atrushkevich V.G. was reproduced. (Patent RU No. 2625295 dated 07/12/2017). Assessment of the dynamics of the cytokine status of blood serum was carried out by the level of pro-inflammatory (IL-1β, TNF, IL-6, IL-17), anti-inflammatory (IL-4, IL-10) and regulatory (IL-2) cytokines using enzyme-linked immunosorbent assay using reagent kit "Bender MedSystems". Results. The study revealed the presence of an imbalance in the cytokine system, characterized by a violation of the physiological balance between pro-inflammatory and anti-inflammatory cytokines with a predominance of the former. Hyperproduction of cytokines persisted throughout the experiment with an increase in the above uncoupling by day 25, which indicates the formation of an immunoinflammatory process in the periodontium. Conclusion. The data obtained during the study confirm the presence of an imbalance of the cytokine network, which indicates the formation and progression of the inflammatory process of the periodontal complex, and also necessitates the introduction of drugs that inhibit the synthesis of pro-inflammatory mediators into complex therapy.
