Abstract. The results of the effect of complex treatment on periodontal microcirculation in patients with chronic periodontitis occurring with an iron deficiency state. Purpose of the study: to study periodontal microcirculation in patients with chronic periodontitis occurring against the background of iron deficiency states. Materials and methods: As the research sources, 100 patients who applied to the Samarkand regional dental clinic suffering from chronic periodontitis and iron deficiency were selected. The patients were divided into 2 groups, of which 1 main group consisted of 50 patients who received glycodent gel and an iron preparation (combined iron (II) sulfate - sorbifer durules / ascorbic acid). The second group received the generally accepted standard therapy for chronic periodontitis. The diagnosis of iron deficiency states was established by determining the parameters of iron and ferritin in the blood. Microcirculation was studied using the "Lazma" apparatus (Russia). Results and discussion: A positive effect on microcirculation of the complex of treatment with glycodent gel and an antianemic drug for chronic periodontitis with an iron deficiency state was revealed.
