Subject of the study: to identify the relationship between the quality of life in patients with chronic generalized periodontitis and moderate periodontal disease with indicators before and after periodontal treatment. Objective: to determine an integral assessment of the quality of life in patients with chronic generalized periodontitis and moderate periodontal disease before and after traditional periodontal treatment and with the use of new technologies. Methodology. The study involved 120 patients aged 45-65 years with a diagnosis of chronic generalized periodontitis and moderate periodontal disease. The patients were divided into 2 groups: the main group (60 people) and the control group (60 people). The integrated assessment related to dental health was determined based on the questionnaire for determining the "dental health impact Profile OHIP-14"index. Patients of the main and control groups completed the questionnaire 3 times: before treatment, 6 and 12 months after treatment. Results. Periodontal treatment with the use of new technologies in patients with chronic generalized periodontitis and periodontal disease of moderate severity showed an improvement in 3 main indicators of the quality of life level for the problem with food intake, the problem in communication and the problem in everyday life. Conclusion. The use of directed tissue regeneration and the method of carboxytherapy for local treatment in patients with moderate periodontal disease in the main group compared to traditional treatment showed a significant positive dynamics of subjective signs. Reducing the clinical manifestations of diseases allowed patients to lead a full life, without experiencing the inconvenience associated with eating and communicating with people.

Subject. Data on the prevalence and epidemiology of chronic periodontitis are presented. The main treatment protocols for this pathology and the most common complications arising from its neglect or inadequate treatment are presented. The goal is to conduct a retrospective analysis of the incidence of chronic generalized periodontitis in the period from 2015 to 2019 in medical institutions of the dental profile of the city of Samara Methodology. During the study 21368 medical records were studied in the period from 2015 to 2019, and errors in filling out 2910 medical records of primary patients were analyzed. The quality of conducting 18458 medical records was assessed in the provision of dental care for patients with a diagnosis of chronic periodontitis. Statistical processing of the material was carried out using the statistical program package “Statistica” for the formation of clear approaches in the diagnosis, treatment methods and prevention of this pathology. Results. An analysis of medical records showed that the highest prevalence of chronic periodontitis was observed in the 55―64-year-old age group (29.82 % of those examined), while 67.5 % of the patients showed a generalized form of chronic periodontitis, and 32.5 % localized. The treatment of such patients was carried out comprehensively and included both conservative methods of treatment, as well as surgical and orthodontic treatment. Stabilization in chronic generalized and localized periodontitis of mild degree occurred in 45 % of patients, in medium ― in 33.4 %, and in severe ― in 8.5 %. Conclusions. The frequency of occurrence of patients with a diagnosis of "chronic periodontitis" by referral to dental clinics is about 86 %. At the same time, the positive outcome of the treatment currently remains at an extremely low level, especially in the treatment of patients with a severe degree of development of chronic periodontitis. This is largely due to the neglect by the dentists of the proposed treatment protocols.
