Relevance of the research topic. The oral cavity is one of the most diverse microbiomes in the human body, which is divided into several biotopes: oral mucosa, dental plaque, gingival fluid and gingival sulcus zone and others. The biotope of the gingival sulcus is unique in that quantitative and qualitative changes in the microbial communities of this microecological system can lead to the development of the main dental diseases - gingivitis, periodontitis and caries. The scientific literature on the etiology of these diseases determines the microbial landscape of the gingival sulcus as the dominant causative factor. A significant influence on the microflora of periodontal tissues is exerted by various stressors of a modern person. Purpose ― to study the influence of emotional stress on the microbal landscape of the gingival furrow, which is in a state of eubiosis and dysbiosis. Materials and methods. The study involved 67 aged by 35―44 years. A microbiological study was made of the general microbial contamination of the gingival furrow and its colonization by individual microbal species using aerobic and anaerobic cultivation methods. Results. In the state of relative dormancy, 100 % of people without gum disease were found to have an eubiotic condition of the gingival microbal, 100 % of persons with periodontis - the microbal of the gingival groove were in a state of dysbiosis. Summary. The influence of the stressor on the disorder of the balance of the microbial homeostasis of the dental gingival slit causes an increase in the imbalance of microbial associations in the form of a decrease in the comensal microflora and an increase in the opportunistic pathogenicity.
Relevance of the research topic. The oral cavity is one of the most diverse microbiomes in the human body, which is divided into several biotopes: oral mucosa, dental plaque, gingival fluid and gingival sulcus zone and others. The biotope of the gingival sulcus is unique in that quantitative and qualitative changes in the microbial communities of this microecological system can lead to the development of the main dental diseases — gingivitis, periodontitis and caries. Purpose. To study the influence of emotional stress on the microbal landscape of the gingival furrow, which is in a state of eubiosis and dysbiosis. Materials and methods. The study involved 67 aged by 30–49 years. A microbiological study was made of the general microbial contamination of the gingival furrow and its colonization by individual microbal species using aerobic and anaerobic cultivation methods. Results. In the state of relative dormancy, 100 % of people without gum disease were found to have an eubiotic condition of the gingival microbal, at 100 % of persons with periodontis the microbal of the gingival groove was in a state of dysbiosis. Summary. The influence of the stressor on the disorder of the balance of the microbial homeostasis of the dental gingival slit causes an increase in the imbalance of microbial associations in the form of a decrease in the comensal microflora and an increase in the opportunistic pathogenicity. Highlights. 1. Emotional stress may cause the development of periodontal diseases in people who work in the field of law enforcement. 2. On a background of emotional stress the dysbalance of microbial associations increases.
oral Cavity and periodont miCrobiome status through emotional stress a b s t r a c t-Aim. To study the effect of emotional stress on the microbial status of the gingival sulcus, going through eubiosis and dysbiosis, observed in law enforcement officers. Materials and methods. The study involved 67 law enforcement officers aged 30-49. The microbiological study focused on the gingival sulcus total microbial contamination and its colonization with certain types of microbes, employing aerobic and anaerobic cultivation methods. Results. When in a state of relative rest, 100% of the persons with no gum issues were observed to have the eubiotic state of the gingival sulcus microbial status, while in 100% of persons with mild periodontitis the microbial status of the gingival sulcus was found to be in a state of dysbiosis. Conclusion. The stressor effect along with a microbial homeostasis imbalance in the dentogingival gap causes an increase in the microbial associations imbalance, which manifests itself as a decrease in the commensal microflora and an increase in the potentially pathogenic (opportunistic) one.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
