At present, there is no definitive opinion on the effect of thyroid hormones on bone metabolism, as the dualism of their effects has been proven. Various studies show mixed data on metabolic changes in periodontal tissues on the background of thyroid dysfunction. Bone tissue plays a key role in the complex system of mechanisms of regulation of calcium and phosphorus homeostasis in the body. The processes of modeling and remodeling of bone and its mineralization are closely related to calcium metabolism. The biochemical manifestation of osteoporotic processes in the cell bone in generalized periodontitis is a violation of calcium-phosphorus homeostasis on the background of altered markers of bone metabolism. According to the literature, it is known that the main indicator of calcium-phosphorus metabolism is the content of calcium in the serum. However, for the metabolic characteristics of the inflammatory-dystrophic process in the cell bone, it is necessary to study the level of inorganic phosphorus and calculate the molar ratio of calcium / phosphorus. The calcium / phosphorus ratio in the blood is important for the study of calcium deposits in bone tissue. Maintenance of normal bone structure depends on the exchange of phosphates between blood and bone tissue. Magnesium along with calcium is needed to achieve optimal bone mineral density. Magnesium helps maintain normal levels of calcium in bone tissue, its constant renewal in bone, prevents calcium loss. With limited intake of magnesium, the formation of calcium phosphate is inhibited. In order to establish indicators that would reflect the peculiarities of metabolic disorders in the organic matrix of the cell process, which is the main component of the periodontium, we conducted biochemical studies, which included the study of calcium-phosphorus metabolism and serum magnesium in patients with primary hypothyroidism and persons without endocrine pathology. According to the results of studies, in young people with generalized periodontitis on the background of reduced thyroid function, there were violations of calcium-phosphorus metabolism in the serum, which consisted of hypocalcemia and decreased calcium-phosphorus ratio. This may indicate abnormalities in calcium intake and absorption in patients with hypothyroidism. We attribute this fact to the fact that for the normal absorption and metabolism of calcium, thyroid hormones are needed, the production of which is reduced in this endocrine pathology. Data on the negative changes of calcium-phosphorus homeostasis, and especially the violation of calcium absorption by patients with generalized periodontitis in young people with primary hypothyroidism, should be considered when developing schemes for the treatment and prevention of periodontal disease in this category of patients.

The Impact

Introduction. Unfavourable factors of the working environment affect bone tissue, increasing the risk of developing osteoporosis in workers of harmful industries, which is an urgent social and hygienic problem due to the high prevalence and severity of medical and social consequences. The aim of the study was to investigate the impact of industrial vibration and physical overload on the markers of bone metabolism in industrial workers. Materials and methods. One hundred fifty-two employees of mining and mechanical engineering enterprises in contact with industrial vibration and physical overload were examined. The assessment of bone tissue metabolism in the workers was carried out by the method of solid-phase enzyme immunoassay to determine biochemical markers of bone metabolism: bone alkaline phosphatase, osteocalcin, C-terminal serum telopeptide, cathepsin K, as well as indicators of calcium-phosphorus metabolism. X-ray densitometry was used to assess bone mineral density. Results. There was a significant decrease in the markers of osteogenesis: the concentration of CSF (14.26 ± 4.13 and 18.69±5.28, respectively, p< 0.05) and osteocalcin (12.23±4.15 and 17.84±5.17, respectively, p < 0.05) and an increase in the markers of bone resorption: the level of beta-CrossLaps (0.629±0.162 and 0.361±0.095, respectively, p = 0.002) and the level of cathepsin K (12.49±5.28 and 0.59±0.02, respectively, p < 0.001) in workers of industrial enterprises exposed to physical factors of production. The correlation between the markers of bone metabolism and the experience of exposure to adverse working conditions was established. Conclusion. Combined exposure to physical labour factors is a predictor of calcium-phosphorus metabolism and bone metabolism disorders, increasing the risk of metabolic osteopathy in industrial workers.

This article provides a review of current literature on the effect of various doses of vitamin D on the parameters of calcium and phosphorus metabolism in patients after bariatric surgery. The decrease of bone mineral density is one of the most frequent complications of the bariatric surgery, which increases the risk of fractures. There are many different mechanisms for impaired mineral metabolism after bariatric surgery, but a decrease in the absorption of calcium and vitamin D plays a key role in this process. Vitamin D is the most important endocrine regulator of calcium homeostasis in the body, which provides the absorption of 90% of calcium in the gut. Patients with morbid obesity have a high risk of vitamin D deficiency even before surgery, which may worsen after operation and in the absence of timely treatment lead to severe disturbances of calcium and phosphorus metabolism. It was found that high doses of vitamin D after bariatric surgery can improve parameters of bone metabolism, and, as a result, prevent fractures after surgery, which generally has a beneficial effect on the quality of life and labor prognosis. The results of the studies available to date open up new opportunities for the prevention and treatment of postoperative complications associated with impaired bone metabolism.

Periodontal disease in the adult population is one of the most pressing problems of dentistry around the world. Thanks to the introduction of modern technologies in practice, it was possible to identify the main mechanisms of the development of this disease at the molecular and genetic level. The interaction of periodontal pathogens with immune factors of antimicrobial protection of the body is the basis of periodontal tissue inflammation and further leads to the destruction of the alveolar bone. Epithelial cells of the gum mucosa play a crucial role against periodontal pathogenic bacteria. Factors of innate immunity play a role not only in antimicrobial protection, but they also support the conditions necessary for the healing and regeneration of periodontal tissues. Therefore, various therapeutic approaches that affect the factors of innate immunity are considered as effective and promising. Clinical examination and determination of factors of innate immunity were performed in 115 patients. Healthy individuals made up a group of 30 people. Patients with chronic generalized periodontitis with varying degrees of severity were 85 people. Each patient underwent orthopantomography on the orthopantomograph Orthophosis XG DS/Ceph (SIRONA Dental System GmbH, Germany) in order to assess the state of the bone tissue of the jaws (the degree of destruction of the cortical layer, the degree of resorption of the interalveolar partitions). Targeted intraoral radiographs were used to assess the state of bone tissue and the quality of surgical treatment. Immunological methods of research were carried out in several stages. The findings of this article make the claim that the use of autologous complex immunopeptides in the surgical treatment of periodontitis reduces the time of achieving a therapeutic effect 2 times, resulting in the rapid relief of the symptoms of inflammation and acceleration of reparative processes.

Recent studies have demonstrated the importance of bone as an endocrine organ that produces biologically active substances, which regulate both local bone metabolism and metabolic functions throughout the body. In the process of bone remodeling (formation/destruction), the active cells secrete specific biomarkers that help detect osteometabolic dysfunction. Among bone hormones, osteocalcin plays an important role as a coordinator of bone modeling processes, energy homeostasis, metabolism of glucose, lipids and minerals. Osteocalcin is a structural protein of the bone matrix, which is synthesized by osteoblasts and enters the bloodstream in the process of bone resorption. The level of osteocalcin in the serum is used as a specific marker of bone formation. Osteocalcin promotes pancreatic β-cell proliferation and insulin secretion, and also affects the insulin sensitivity of peripheral tissues. The inverse association of glycemia with the level of osteocalcin was revealed. Patients with type 2 diabetes mellitus usually have normal or even slightly elevated bone mineral density compared to age-appropriate controls. Decreased bone quality and increased risk of fractures are associated with changes in bone microarchitecture and local humoral environment. An imbalance in osteoblast/osteoclast activity may be due to oxidative stress and the accumulation of glycosylation end products, which contributes to chronic inflammation and bone resorbtion in patients with diabetes. It is shown that the level of osteocalcin in the blood serum is significantly reduced compared to healthy controls, both in patients with type 1 diabetes mellitus and, especially, in type 2 diabetes mellitus. Given the importance of developing new approaches to the diagnosis and correction of metabolic disorders in diabetic patients, the study of the influence of bone hormones on hormonal and metabolic parameters and bone status, including the risk of fractures, remains relevant in modern diabetology.

The aim of the study was to investigate age-related changes in bone mineralization indicators in the lumbar vertebrae in women with normal body weight living in the conditions of the Northern region.Material and methods. A complex somatometric examination and quantitative assessment of the bone tissue mineral density in the lumbar vertebrae were performed according to dual-energy X-ray absorptiometry of a group of Slavic women (n=127) with a normal body weight (BMI values from 18.5 to 24.9 kg/m2) aged 20 to 87 years, permanently residing in the Republic of Karelia. Statistical processing of the material was performed using the program "STATISTICA 6.0".Results. The BMI values in women increased significantly every decade of life. Direct correlations of mineral bone density (MBD) with the body length (r=0.46, p<0.001), with the body surface area (r=0.46, p<0.001), with absolute muscle mass (MM) (r=0.39, p<0.001), and with body mass (r=0.29, p<0.001) were revealed. No significant correlation with the adipose mass was found. The incidence of low MBD of the lumbar vertebrae was 48%: osteopenia was in 29%, osteoporosis was in 19% of women. The analysis of the component composition of the body in women with different levels of bone mass showed significant differences in the absolute content of muscle mass.Conclusion. In women with a normal BMI, body weight and muscle mass play an essential role in maintaining lumbar vertebrae bone mineral density.

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.

Anticoagulant and antiplatelet agents are used to prevent stroke and thromboembolic events. There is insufficient data on the effect of these drugs on bone tissue. In addition, the available data are ambiguous, which increases suspicion when used in individuals at high risk of osteoporosis. The article provides data on the effect of anticoagulant and antiplatelet agents on bone metabolism, bone mineral density and the fracture risk. Literature data indicate a negative effect of heparin on bone tissue, which is increase the risk of fractures. Low molecular weight heparins has lower effect on bone tissue than heparin. It is known that vitamin K antagonists significantly affect bone metabolism and markers of bone formation, however, data on the effect on bone mineral density and the risk of fractures are contradictory. Direct oral anticoagulants are relatively safe in relation to bone tissue. Data on the effects of antiplatelet drugs on bone are ambiguous.

Introduction. A research was conducted of the features of the structural and functional state of bone tissue in patients with generalized periodontitis with rheumatoid arthritis who live in different anthropogenically loaded areas. Aim. The aim of the research is to assess the bone tissue mineral density according to the indicators of densitometric researches and the level of a marker of bone metabolism in generalized periodontitis of I and II degree of severity. Material and methods. We examined 105 patients with GP of the I and II degree of severity, among whom were patients with rheumatoid arthritis who live in environmentally favorable and unfavorable areas. Peculiarities of the structural and functional state of bone tissue were assessed using an ultrasonic densitometer Sunlight Mini Omni TM and the level of a marker of bone tissue resorption of deoxypyridinoline in urine. Results. Patients with generalized periodontitis with rheumatoid arthritis who live in environmentally unfavorable areas, found the largest number of people with signs of osteopenia, osteoporosis and elevated levels of deoxypyridinoline. In particular, in generalized periodontitis of the II degree of severity with osteopenia – 14 people (48.27%), with osteoporosis – 9 people (31%), the level of deoxypyridinoline determined in women was 12.03 ± 0.16 n/mol, which in 2.2 times significantly higher than the group of healthy (p < 0.001). Conclusions. According to densitometric parameters and the level of deoxypyridinoline in the urine, the acceleration of bone tissue resorption in patients with generalized periodontitis of the II degree of severity with rheumatoid arthritis who live in environmentally unfavorable areas was established.
