The aim of the research is to increase the effectiveness of treatment of patients with chronic catarrhal gingivitis living in ecologically favorable conditions and in ecologically polluted regions of Precarpathian, by adding to the complex therapy of quercetin and chlorhexidine dent. The results of research by a number of scientists indicate that the use of quercetin in complex therapy helps to restore the antioxidant system, improve oxygen uptake by tissues and peripheral circulation, improve the rheological properties of the patient's blood. These properties of the drug were used by us in the research.

We studied changes in periodontal tissues in children living in ecologically favorable conditions and in ecologically polluted regions of Precarpathian, conducted a comparative characterization of changes in periodontium and proposed a treatment plan for patients with chronic catarrhal gingivitis, supplemented with chlorhexidine dent and quercetin.

We examined 60 children with chronic catarrhal gingivitis living in the contaminated areas of Precarpathian (Burshtyn) and 15 people with intact periodontium living in environmentally stable conditions. All patients underwent a full range of treatment measures, taking into account the removal of dental plaque and rehabilitation of the oral cavity. In 1 group of patients (30 people) patients were treated with chlorhexidine, calendula and chamomile infusion and 1% mefenamine paste. Patients of group 2 (30 people) - the drug quercetin on the mucous membrane of the gums under the individual gingival cap and chlorhexidine dent in the form of oral baths.

In order to compare the two groups, an index assessment of the condition of periodontal tissues and a study of rheographic parameters of periodontal tissues were performed.

The results of the research did not show a significant difference between clinical and laboratory parameters in patients 1 and 2 groups before treatment (p> 0.05), but they differed significantly from those in the comparison group (p <0.05), which indicates the fact that unfavorable environmental living conditions have an impact on the course of periodontal disease in children. We obtained a significant difference in the blood supply to periodontal tissues in patients with chronic catarrhal gingivitis compared with (p <0.05). The results of the research showed that the use of quercetin and 0.12% chlorhexidine solution in the complex treatment of patients with chronic catarrhal gingivitis provided a significant improvement in clinical parameters and laboratory characteristics of periodontal tissues in children living in different environmental conditions, and provided stabilization of these indicators in long-term observation. The use of the proposed scheme of treatment of patients with chronic catarrhal gingivitis stimulates metabolic processes in periodontal tissues, reduces cyanosis, edema of periodontal tissues according to the results of rheography of periodontal tissues. After treatment, we observe the normalization of the rheological characteristics of the gums, which indicates an improvement in blood circulation in the periodontal tissues in these patients (normalization of qualitative and quantitative characteristics of rheograms).
