Among dental diseases, periodontal diseases rank one of the leading places and are considered as the most pressing issues of modern dentistry. The presence of concomitant somatic pathology, in particular, cardiovascular, endocrinological, autoimmune diseases is an important factor that considerably determines the course and prognosis of periodontal disease. Metabolic syndrome is regarded as an urgent social and medical issue due to its high prevalence among the general population and its contribution to the development and progression of cardiovascular disease. The number of reports and scientific interest in the metabolic syndrome has grown up significantly in recent years, but despite the significant number of studies, the oral microbiome in patients with periodontal disease and underlying metabolic syndrome is still remaining insufficiently studied. The aim of this work was to investigate the species composition of the microflora in periodontal pockets and the frequency of excretion of certain types of microorganisms in the acute generalized periodontitis in patients with metabolic syndrome. A microbiological study was performed in 30 people with metabolic syndrome and generalized periodontitis, who formed the main group, and in 30 people with generalized periodontitis without endocrinological pathology, who formed a comparison group. The results of microbiological examination indicate pathological changes in the oral microbiome in the patients with metabolic syndrome demonstrating a predominance of periodontal pathogens. It can be assumed that the components of the metabolic syndrome can initiate and support microbial invasion thus resulting in the inflammatory reaction of periodontal tissues. There is a similarity between pathogenetic mechanisms of metabolic syndrome and periodontal disease that lead to the impairment of all types of metabolism: protein, lipid, mineral, carbohydrate. As a consequence, this contributes to the progressive destruction of oral tissues. The obtained data enable to suggest the dependence between the presence of the patient's metabolic syndrome and the development of intensive damage to periodontal tissues.

Periodontal diseases are inflammatory and destructive diseases of the dentogingival complex associated with specific periodontal pathogens inhabiting periodontal pockets. Periodontal diseases lead to damage of the periodontal tissues supporting the teeth (bone and connective tissue) and affect the quality of life of the affected individuals: poor alimentation, tooth loss, social and financial problems. Although it is generally considered that the disease has multifactorial etiology, data show that some specific Gram-negative microorganisms in the subgingival plaque biofilm play a major role in the initiation and progression of periodontitis. Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia form a consortium in the subgingival biofilm and are regarded as the principal periodontopathogenic bacteria. Other microorganisms that have been implicated as predominant species in the disease process are: Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Prevotella intermedia, Campylobacter rectus, Peptostreptococcus migros, Eikenella corrodens. In periodontitis, the initiation of the disease is the colonization of the tissues by these pathogenic species. The next step is bacterial invasion or invasion by pathogenic products into the periodontal tissues, interactions of bacteria or their substances with host cells, and this directly/indirectly causes degradation of the periodontium, resulting in tissue destruction. Keywords: periodontal disease, periodontal pathogens, microbiology.

The article presents a retrospective review of professional domestic and foreign literature on modern aspects of treatment of inflammatory periodontal diseases, including vector therapy, plasmalifting, which can be used in various forms of this pathology. Periodontal diseases are one of the most pressing problems of dentistry, which has not only general but also great social significance, due to the high prevalence, intensity of the process, the subsequent formation of chronic odontogenic foci of infection, tooth loss at a young age and adverse effects on the body. Treatment of periodontal disease is a complex and lengthy process that includes general methods of influencing the pathophysiological processes occurring in the body, both local - therapeutic, orthopedic and surgical measures. Before planning treatment, the dentist should determine the patient's medical and dental history, conduct clinical and radiological examinations, determine the degree of loss of the alveolar ridge, functional disorders of the dental system and the possibility of their correction. Depending on this, determine the plan of treatment and rehabilitation measures, the sequence of medical interventions. The main task of periodontal treatment is to optimize the conditions for maintaining a healthy dentition and restoring its physiological functions. The difficulty of treating inflammatory periodontal diseases is that known and standard methods (antibacterial therapy and courses of local therapy) do not always give a positive result and a long period of remission. Therefore, to improve the quality of medical care for patients with periodontal pathology, it is necessary to introduce new innovative methods of treatment in dental practice. Given the patterns of pathophysiological processes occurring in periodontal tissues and bone tissue of the alveolar process, to date, several stages of treatment and rehabilitation measures have been proposed. The first stage is the elimination of the pathogenic action of microbial factors and inflammatory processes in periodontal tissues. Microbial invasion and the inflammatory reaction of periodontal tissues caused by it activate the processes of osteoclastical bone resorption. The task of the second stage of treatment and rehabilitation measures is to restore the physiological structure of gums and bone by normalizing metabolic processes in periodontal tissues, reducing the activity of resorption processes and stimulating reparative osteogenesis in the bone tissue of the alveolar process and the body in general, surgical treatment. At the third stage of treatment and rehabilitation measures, teeth with a significant degree of atrophy of the alveolar process are removed, which cannot be used for prosthetics. To restore the integrity of the dentition, even distribution of masticatory load, appropriate prosthetics are performed. The use of the latest methods contributes to the effective treatment of periodontal disease in the early stages, stabilization of the process at deeper stages, in some cases helps to avoid surgery.

Introduction: Periodontal Gram-negative bacteria and their products can initiate inflammatory responses in periodontal tissues with systemic consequences. They are associated with the pathogenesis of atherosclerosis and ischemic stroke. Local inflammation and oxidative stress play a crucial role in the pathophysiology of intracranial aneurysms (IAs). Under the hypothesis that the severity of periodontal disease is associated with the formation and rupture of IAs we assessed which periodontal pathogens contribute to the pathogenesis of IAs. Methods: We enrolled patients with ruptured- (n=5, age 60±11.9) and unruptured IAs (n=13, age 67±6.1) and controls without IAs (n=7, age 58±8.5); their prior informed consent was obtained. The severity of periodontitis was recorded using the community periodontal index (CPI) of the Treatment Needs code. Subgingival plaques (n=23) were evaluated with the quantitative real-time PCR assay to check for the Gram-negative bacteria Aggregatibacter actinomycetemcomitans (Aa), Fusobacterium nucleatum, Treponema denticola, Prevotella intermedia (Pi), Tannerella forsythia, and Porphyromonas gingivalis (Pg). Plasma IgG titers of antibody against Pg, Pi, Aa, and Eikenella corrodens were evaluated by ELISA. Results: The CPI was significantly higher in patients with IAs than the controls (2.7 vs 1.9, p<0.05) and their DNA level of subgingival plaques and their plasma IgG titers of Pg were also higher. Periodontal disease was more severe and the plasma IgG titers of Pg were higher in patients with ruptured- than unruptured IAs, suggesting that Pg is associated not only with the formation but also the rupture of IAs. Conclusions: We present evidence that severe periodontal disease and Pg infection may be involved in the pathophysiology of IAs. The management of periodontal diseases may help to prevent the formation and rupture of IAs.

Topicality. Over the past few years, scientists have attracted the attention of the problem of studying the relationship between metabolic syndrome and periodontal disease. Topics of risks associated with the association with various metabolic disorders have become one of the most important research topics in periodontology. Oral fluid plays a leading role in the proper functioning and maintenance of homeostasis of the entire periodontal tissue complex, is a mediator of the combination of its structures with the environment and an important nutrient substrate for the microflora of the oral cavity. The aim of the study. In order to study the quantitative and qualitative changes of oral fluid in periodontal diseases on the background of the metabolic syndrome, the rate of secretion of mixed saliva, its viscosity and acid-base balance were studied. 2 groups were formed for research: basic and comparative. Materials and methods. The main group included 30 people with inflammatory-dystrophic lesions of the periodontium on the background of metabolic syndrome, the comparison group consisted of 30 people with periodontal disease without endocrinological pathology. Results and discussion. The results of the study revealed homeostatic shifts in the oral biosystem of persons with periodontal disease on the background of metabolic syndrome: a decrease in salivation may indicate a violation of the secretory function of the salivary glands on the background of metabolic disorders, which naturally affected the increase in saliva viscosity. Conclusions. The predominance of acidosis in the oral cavity and the reduction of the protective properties of saliva becomes an important factor in creating a periodontopathogenic situation in the oral cavity and aggravating the course of periodontal disease in this category of patients. Key words: metabolic syndrome, periodontal disease, oral fluid, physicochemical properties.

The article presents a review and analysis of relevant available literature sources on etiopathogenetic mechanisms of periodontal disease and liver diseases of viral aetiology, and, in particular, hepatitis B and C viruses. Significant prevalence, pronounced polymorphism of clinical hepatic and extrahepatic manifestations, the incidence rate of liver cirrhosis and hepatocellular carcinoma allows us to consider hepatitis of viral aetiology as a medical and social challenge. Multi-vector liver dysfunctions can cause oral presentations in this group of patients, and in particular, in their periodontal tissues. Viral liver damage is associated with significant impairment of the microbiocenosis in gingival sulcus and periodontal pockets. Dysbiotic changes are characterized by an increase in the number of opportunistic pathogens and anaerobic periodontal pathogens. Exacerbation of dysbiosis along with deterioration of oral hygiene occurs as a consequence of reduced local resistance and hyposalivation due to the sialotropic properties of hepatitis C virus. Significant pathogenetic role in the development of periodontal disease is played by disorders of metabolic and synthetic functions of the liver, as well as hormonal imbalance, metabolic disorders, immune-mediated damage, induction of autoimmune mechanisms and cytokine imbalance. The formation of hepatogenic osteopenia and osteoporosis enhances the loss of bone mass of the alveolar processes in the jaws and, accordingly, the resorption of bone tissue with the further progression of more aggressive forms of generalized periodontitis.

Abstract Snus is a tobacco product containing nicotine and is widely used in Sweden. Now it is becoming more and more popular among young athletes and teenagers in Latvia, even though it is forbidden for sale in the European Union. The use of snus is considered to induce various oral illnesses, especially periodontal diseases, diabetes, heart and cardiovascular diseases as well as cancer. Comparison of the microbiome of saliva and tooth biofilm in snus tobacco users with that in people who never use snus showed that, the number and diversity of periodontal pathogenic microorganisms was much higher in samples taken from snus users. The observed features of the oral microbiome, such as the presence of periodontal pathogens and their high concentration, may have adverse effect on periodontal tissues of snus users and their general health in the future.

Relevance. The modern view of periodontitis as a dysbiotic disease that occurs as a result of changes in the microbial composition of the subgingival region is considered in a systematic review.Purpose. To study a new paradigm of development of generalized periodontitis.Materials and methods. Randomized controlled trials (RCTS) were selected for the study, including cluster RCTS, controlled (non-randomized) microbiological and clinical studies of the oral microbiome in adult patients with generalized periodontitis over the past 10 years.Results. The transition from a symbiotic microflora to a dysbiotic pathogenic community triggers the host's inflammatory response, which contributes to the development of periodontal diseases. Modern ideas about periodontal pathogenic bacteria dictate new requirements for the treatment of periodontal diseases. The second part of the review examines the microbial profiles of periodontal disease in various nosological forms, the mechanisms of the immune response and approaches to the treatment of periodontal disease from the perspective of biofilm infection.Conclusions. As follows from modern literature periodontitis is to a certain extent caused by the transition from a harmonious symbiotic bacterial community to a dysbiotic one. Recent scientific studies have shown that not single microorganism is not able to cause disease but the microbial community as a whole leads to the development of pathology.

The diagnosis of periodontal disease is mainly based on use of clinical and radiographic evidence. In this study we employed a quantitative PCR analysis of Aggregatibacter actinomycetemcomitans and Treponema denticola as species strongly involved in periodontal diseases, burden in periodontal pockets to detect the main sampling factors that interfere with qPCR results. From 22 patients with advanced periodontal disease, subgingival plaque was comparatively collected by paper points and periodontal Gracey curettes. Samples were collected from the same situs in presence of gingival bleeding and absence of bleeding. The concordance and agreement of results between samples were assessed. The present study demonstrates that subgingival plaque sampling with sterile absorbable paper points is often accompanied by gingival bleeding resulting in quantification biases of periodontal pathogens.

Background. Periodontal tissues inflammatory diseases are widespread among young people. Objective. This study was aimed at elaborating the method to assess risks of periodontal inflammatory diseases and determining its efficacy depending on the state of dental tissues, gum tissues and sex.          Methods. The study included 182 students (93 men, 89 women) aged 19-29: 22 individuals had no lesions of hard dental tissues and no signs of periodontal disease; 51 individuals were found to have DMF index <6; 52 individuals – DMF index ≥6; 57 individuals were diagnosed with chronic catarrhal gingivitis. Primary groups were formed in autumn; re-examination was carried in spring. The research participants were assessed for detection of risks of periodontal inflammatory disease by the method developes by the authors (Patent UA 54041). Results. The study revealed that the risk of development of preiodontitis increases in individuals with high caries and gingivitis intensity. In spring, more individuals suffer from microbial imbalance in in the composition of gingival sulcus fluid and decrease in the mean stability coefficient value that indicates an increased risk of inflammatory periodontal disease development. Women were less likely to experience seasonal dysbiotic changes in the gingival sulcus fluid composition compared with men. Conclusions. The method suggested for assessment of the risk of periodontal inflammatory diseases is of high informativeness. It allows clinicians detecting early pre-nosological signs of oral microbiocenosis imbalance that enhances the effectiveness of early diagnosis of inflammatory periodontal diseases.

The review of the scientific literature is devoted to the topical issues of studying the etiology of periodontal diseases, which are one of the most common and complex pathologies of the maxillofacial region. Analysis of recent studies proves a stable relationship between the development of periodontal diseases and disorders in the immune system, the neurohumoral system, metabolic disorders, genetic predisposition, and so on. The article presents the data obtained in the course of studying the literature on the role of disorders in the functioning of individual organs (gastrointestinal tract, liver, lungs, heart, and urinary system) in the development of chronic periodontal diseases. The article notes that the anatomical and physiological proximity of the periodontal and digestive tract tissues, the generality of innervation and humoral regulation create prerequisites for the involvement of periodontal disease in the pathological process in diseases of the gastrointestinal tract. One of the main etiological factors in the development of inflammatory diseases of the gastrointestinal tract and periodontium is Helicobacter pylori, which is found in the loci of the oral cavity: in the oral and gingival fluid, on the mucous membrane of the tongue and cheeks, and in the periodontal pockets. It is pointed out that the liver also occupies a special place in the development of periodontal diseases, which is explained by the performance of its significant functions for the human body: regulatory, metabolic, antitoxic and other. There is evidence that the pathology of periodontal disease plays a leading role in the structure of dental diseases in patients with chronic obstructive pulmonary diseases, which is clinically manifested by symptoms of generalized periodontitis of the І-ІІ degrees of development and its complications - partial or complete secondary adentia, and with tooth preservation - defects in dental series and violations of occlusion, function, aesthetics. Scientists suggest a general biological mechanism for the development of generalized periodontitis and cardiovascular diseases, linking the development of periodontal diseases in patients with cardiovascular pathology with microcirculatory disorders. The dependence of the severity of inflammatory changes in the periodontal tissues on the disturbances of salt metabolism in urolithiasis is proved. The data obtained indicate that diseases of the internal organs contribute to the structural damage of periodontal tissues and they are a risk factor for periodontal diseases, which necessitate the presence of not only theoretical knowledge and practical skills in dentistry, but also their awareness of the features and clinical manifestations of somatic pathology. An urgent and justified step in the treatment of periodontal diseases is also the involvement in the process of rendering complex dental care to internist doctors capable of quickly and qualitatively assessment the condition of the internal organs and the basic systems of the patient's body.
