The susceptibility to the development and progression of inflammatory periodontal diseases, which depends on genetic and external factors (smoking, stress, oral hygiene), varies widely. In the development of these diseases, an important role is played not only by the presence of periodontal pathogenic microorganisms, but also by the presence of congenital or acquired immunodeficiency, immunoregulatory defects. The immune system plays a key role in the physiological and pathological processes of periodontal tissues. In this regard, IL17, produced by CD4+ Th cells, which has both Pro-inflammatory and protective activity, is of particular interest in the pathogenesis of periodontitis. The aim of study was to identify the relationship between polymorphic loci of the IL-17A (rs2275913) and MMP-1 (rs1799750) genes and clinical manifestations of chronic periodontitis in petrochemical workers. Dental examination was performed in 92 ethylene oxide production workers with chronic periodontitis and 74 patients with chronic periodontitis who did not come into contact with chemical factors (control group). Genotyping of polymorphisms rs2275913 of the IL17A gene and rs1799750 of the MMP1 gene was performed by allele-specific real-time polymerase chain reaction (PCR). Hygienic assessment of the degree of air pollution of the working area with harmful substances was carried out by gas chromatography according to the guidelines for the determination of harmful substances in the air № 5098-89, № 3119-84. When comparing the results of studies of both groups, there were no statistically significant differences in the frequency distributions of allelic variants and genotypes of the IL-17A and MMP-1 genes. The AA/AG genotypes of the IL-17A gene were associated with an increased risk of severe disease compared to the GG genotype in workers in the main group (OR=6.1; 95% CI 1.33-28.5; p=0.021) and in the control group (OR=7.26; 95% CI 1.34-39.25; p=0.016). Carriers of the A allele in the control group increased the risk of severe chronic periodontitis by 2.4 times compared to carriers of the G allele (OR=2.41; 95% CI 1.19-4.87; p=0.014). During the dental examination of employees of the ethylene oxide plant, the clinical course of periodontal diseases was more severe in comparison with the control group, and the number of patients with severe periodontitis was twice as high. It was found that the AA/AG genotypes of the IL-17A gene and the carrier of the A allele are associated with increased susceptibility to the development of severe chronic periodontitis. The association between the MMP-1 gene polymorphism and the risk of severe forms of chronic periodontitis has not been established. A risk factor for the development of inflammatory periodontal diseases in employees of the petrochemical complex is a complex of harmful production factors.

Inflammatory Status

Periodontitis is a chronic inflammatory disease of the vascularized supporting tissues of the teeth. Angiogenesis (neovascularization) is the budding of new capillaries and is thought to be an essential process in the development of chronic inflammatory diseases. Inflamed tissues (such as gingiva coincident in periodontal disease) have evidence of enhanced expression of inflammatory mediators, many of which can promote angiogenesis. Of the various cytokines and growth factors that are involved in angiogenesis, the most potent agent that acts specifically on vascular epithelium is Vascular Endothelial Growth Factor. Even though angiogenesis is a prominent feature of both inflammation and healing, information about its role in periodontal lesions is limited. Hence the aim of the present study was the immunohistochemical evaluation of the expression of VEGF in the gingival tissues of chronic and aggressive periodontitis patients compared to the healthy controls. The present study was carried out in a total of 45 subjects with age range of 18-55 years, reporting to the Department of Periodontology, Rajarajeswari Dental College and Hospital, Bangalore. Gingival tissue samples were collected from all the 45 subjects and categorized into three groups based on their clinical findings as follows: Group 1 (Healthy), Group II (Chronic Periodontitis), Group III (Aggressive Periodontitis). Following sample collection, immunohistochemical staining of tissues was carried out and evaluation was done to compare the grades of expression of VEGF in the three groups. The expression of VEGF in blood vessels was also quantitatively evaluated. The results were statistically analyzed using Kruskal Wallis ANOVA and Mann Whitney test. There was a statistically significant higher expression of VEGF in both chronic periodontitis and aggressive periodontitis group as compared to the control group. Aggressive periodontitis cases showed higher grades of expression of VEGF compared to the chronic periodontitis cases and healthy controls. However, the difference in expression of VEGF was not statistically significant between the two forms of periodontitis. The presence of VEGF in both chronic and aggressive periodontitis clearly indicates the potent role played by VEGF as an inflammatory agent in the initiation and progression of periodontal diseases. Thus, VEGF might be used as a potential vascular marker for the assessment of severity and inflammatory status in periodontal disease.

Smoking is associated with significantly increased risk of diseases of organs and tissues of the oral cavity, especially periodontal pathology and cancer of the mouth.The aim of the study – to investigate the prevalence, structure and clinical course of periodontal tissue diseases in people prone to regular active smoking.Materials and Methods. A study of 120 visitors who had undergone preventive examinations in the Clinic of Zbarazh Central District Municipal Hospital exposed to regular active smoking was performed. To assess the degree of inflammation in periodontal tissues we used marginally-papillary-alveolar index, periodontal index, the Green-Vermilyon index.Results and Discussion. Dental examination of persons exposed to regular active smoking, revealed periodontal disease in 102 individuals (85.0 %), intact periodont – 18 persons (15.0 %). At the same time, investigation of 30 control individuals showed periodontal disease in 12 persons (40.0 %), clinically healthy periodontal tissue – in 18 persons (60.0 %). PMA index of individuals exposed to regular active smoking, treated as severe gingivitis and was significantly higher than data of the control group in 2.5 times. Average numerical values of periodontal index in patients exposed to regular active smoking answered moderate periodontitis and significantly were higher than data of the control group in 4 times. Oral hygiene status in 62 % of those exposed to regular active smoking, was poor, 7 % – very poor, 22 % – satisfactory, 9 % – good. Average numerical values of Green-Vermilyon index in smokers was significantly higher than data of the control group in 3.1 times.Conclusions. Thus, smoking contributes to increasing of diffuse periodontal diseases and deepening of pathological process.

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 aim of the study was to assess the state of the clinical course of periodontal diseases in patients with postmenopausal osteoporosis (OP), depending on the long-term oral administration of various groups of bisphosphonates (BP). The study included 120 women aged 55–65 years with postmenopausal OP for at least three years who took complex antiosteoporetic therapy, including BP in tablet form. The dental examination included an examination of the oral cavity, the study of the pH of the oral fluid, the hygienic state of the mouth (the "Florida Probe" system). According to the results of the study, it was revealed that prolonged treatment of BP in tablets can provoke the development of inflammatory reactions in periodontal tissues. This phenomenon is associated with a shift in the pH of saliva to the acidic side, at which its buffer properties change.

Objective.Type I interferons (IFN), especially IFN-α, have been proposed to underlie the pathogenesis of systemic lupus erythematosus (SLE). Members of the IFN regulatory factor (IRF) family, which regulate IFN expression, have been implicated as risk factors for SLE. Our aims were to investigate the expression of IRF7 and its correlation with disease activity and to explore the association in Taiwanese patients between 2 genetic single-nucleotide polymorphisms (SNP) of IRF7 and SLE.Methods.IRF7 messenger RNA (mRNA) levels were measured in peripheral blood mononuclear cells by real-time reverse transcription polymerase chain reaction in 51 adult patients with SLE and 65 age-matched and sex-matched controls. Their serum IFN-α levels were determined by ELISA and the clinical manifestations were recorded at the same time. Two IRF7 SNP, rs1061501 and rs1061502, were examined by genotyping across 92 patients with SLE and 92 age and sex-matched healthy control subjects.Results.Compared with controls, the expression of IRF7 mRNA was significantly increased in patients with SLE and was positively correlated with both the serum level of IFN-α and lupus disease activity. The distribution of SNP rs1061501 by genotype (CC, CT, and TT) and by allele (C, T) was significantly different between the SLE and the control group (p = 0.028 for genotype and p = 0.009 for allele). There were no significant differences for SNP rs1061502.Conclusion.The results suggest that dysregulation of IRF7 might mediate an excessive production of IFN-α, which then exerts a crucial effect on the pathogenesis of human SLE. The IRF7 SNP rs1061501 TT genotype and T allele are enriched in Taiwanese patients with SLE and thus would seem to be associated with an increased risk of developing SLE.

The clinical and neuropsychological examination of 78 victims after suffering mine explosive wounds (MEW), which included 75 men and 3 women, was carried out. The 1st group consisted of the patients with MEW in combination with traumatic brain injury mild and accompanying complications – 51 (65,4%) patients; the 2nd group was the patients with MEW with peripheral lesion (limb amputation) – 27 (34,6%) patients. The basic number of patients were age 30-40 years (69,2%). The study identified the neurological changes that showed by the manifestation of brain syndrome, cerebral symptomatic, epilepsy syndromes, vegetative dystonia syndrome and its combinations. Average number of associated symptoms of vegetative dysfunction in the patients of the 1st and 2nd groups were significantly (p&#60;0,05) higher relative to the control group. The authors note that the study of the vegetative nervous system identified supra-segmental disorders differed by poly-consistency and a high degree of expressiveness of vegetative dysfunction, with a significant (p&#60;0,05) difference from the parameters of the control group. Disorders in the mental sphere and the failure of adaptation mechanisms in the form of increase of the level of fear and anxiety were identified. The most pronounced changes were observed in patients with MEW and brain injury. Identified dysfunction of the autonomic nervous system in most cases led to an increased risk of desadaptation, which further intensified manifestations of psychopathological disorders.

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.

Introduction: β-thalassemia major is a hereditary blood disease, a main pathogenetic factor of which is the disruption of the synthesis of β-chains of hemoglobin. Inevitable metabolic disorders that occur during regular blood transfusion form an additional risk of damage and cellular modification of organs and tissues, including the oral cavity. Aim: determination of the pathogenetic role of iron metabolism disorder in the development of chronic inflammatory periodontal diseases in patients with β-thalassemia. Material and methods: 12 patients with β - thalassemia major who had periodontal diseases were examined in the Republican Center of Thalassemia in Baku (average age is 18 ± 1.3 years). The control group consisted of 16 somatically healthy individuals with intact gingiva tissues (the average age is 18.0 ± 0.7 years). Serum Iron, ferritin, hepcidin, total iron-binding capacity (TIBC), level of Il2, Il6, Il10, TNFα were measured from peripheral blood samples. To determine the ultra-structural study of the periodontal tissues in patients with β-thalassemia major, the method of electron microscopy studies of gingiva biopsies was used. Results of the study: The study revealed an increase in the level of serum iron and ferritin against the background of a progressively decreasing TIBC in patients with β-thalassemia major. Also activation of pro-inflammatory cytokines - TNFα, Il6, Il10 was observed in homozygous patients. Metabolic indicators are compared with ultrastructural features of cellular elements of a gum. Signs of accumulation of iron in cellular elements both of its own plate and of the epithelial cover were compared. The presence of iron was recorded in immunocompetent cells - macrophages and lymphocytes. Conclusion: Summarizing the data obtained, we can conclude that deproteinization of ferritin cores and their detection both in the cytoplasm and in the nucleoplasm of immunocompotent cells leads to irreversible degenerative changes in cellular elements of the gingiva. The authors link the development of the generalized inflammatory - degenerative process in the periodontium with revealed exchange -structural violations.
