ОЦЕНКА РАСПРОСТРАНЕННОСТИ ОСНОВНЫХ ПАРОДОНТОПАТОГЕНОВ У РАБОТНИКОВ НЕФТЕХИМИЧЕСКОГО ПРОИЗВОДСТВА С ХРОНИЧЕСКИМ ПАРОДОНТИТОМ

Abstract

Background. Periodontitis is a complex, multifactorial inflammatory disease. The prevalence in the adult population is 80-98%. The onset of the disease and the progression of the inflammatory process is associated with the colonization of the subgingival tooth surface with parodontopathogenic microorganisms. Objectives. The purpose is to study the prevalence of five oral microbes in subgingival plaque samples: Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf), Treponema denticola (Td), Prevotella intermedia (Pi) in oil and gas industry employees with chronic periodontitis and identify the presence connection between the clinical manifestations of periodontitis and the microbial profile of periodontal pockets. Methods. The study of periodontal microbiota was carried out in 32 workers in oil and gas industry employees with chronic periodontitis and in 32 patients with chronic periodontitis diagnosed not working in this field. Genomic DNA was extracted and 5 bacterial species were detected using the polymerase chain reaction. Results. Oil and gas industry employees with chronic periodontitis have their own flow peculiarities associated with the systematic influence of production factors. The most prevalent microorganism is Pg (77%), the presence of which is significantly associated with an increase in the depth of the periodontal pocket (PPD), clinical attachment loss (CAL), and an increase in the bleeding on probing (BOP). The pathogenic effect was manifested in the presence of the following microorganisms - the formation of the periodontal pocket in combination of Tf and Td, Tf and Pi, CAL level - Tf and Td, increased BOP index - Pg and Tf. Conclusions. As a result of the study, a connection was established between the red and orange complex bacteria with the clinical signs of chronic periodontitis. There was no significant association between age, smoking and the clinic of chronic periodontitis. Significant impact on the development of inflammatory periodontal diseases in oil and gas industry employees have harmful production factors.
