Subject. The study of the osseous tissue state in the dental implants setting, their functioning after the orthopedic treatment according to the climatic and geographical location. Aim of the study is to estimate the osseous tissue state in the dental implants setting, their functioning after the orthopedic treatment according to the climatic and geographical location. Methodology. The study regarding the estimation of the osseous tissue state after dental implants setting and subsequent orthopedic treatment taking them into consideration was carried out. The analysis of the medical documentation of 180 patients divided into 6 groups according to climatic and geographical location was made. The study was carried out using KBKT through definite control points to reveal the regularity of the region where the patients live, life conditions and the osseous tissue state. Results. The analysis of the received data showed that the patients living in Tyumen had the better osseous tissue state, the level of implants osseointegration and stability of the orthopedic constructions than the persons living in the north of Tyumen region. Conclusion. The level of the osseous tissue state after dental implants setting is different in the groups living in various climatic and geographical conditions including ones of the same region.

A literature review was carried out on an actual, but little studied problem of dentistry — dysfunction of the temporomandibular joint with changes in the musculoskeletal system and an individual typological feature of habitual motor activity in young people. Purpose of the study. Basing on a review of modern scientific literature since 2014, it is necessary to reveal the problems of disorders of the temporomandibular joint, including psychophysiological status in young people, its relationship with changes in the musculoskeletal system and the influence of habitual motor activity on its functioning. Methodology. The data of special literature were studied using scientific search library databases: PubMed Central, Elibrary. The search for original scientific publications was carried out by keywords. This review includes an analysis of 45 scientific sources. Results and conclusions. The literature review systematizes modern scientific data on disorders in the functioning of the temporomandibular joint from a young age, the identification of preclinical and clinical manifestations in students, the influence of stress as a trigger in the development of TMJ pathology, the determination of the habitual motor activity of students and its impact on the work of the TMJ, the influence of posture on the positioning of the articular heads, as well as, with the existing pathology of the TMJ, the effect on the musculoskeletal system, as a manifestation of the defense mechanism. The review also presents current data on the study of temporomandibular joint dysfunction after orthodontic treatment. The review made it possible to identify a number of significant factors contributing to the development of TMJ dysfunction, to substantiate the practical significance of the problem, which is associated with the need for a thorough examination of the TMJ, starting from a young age. This will prevent the development of a complex of dental diseases, the development of pathologies from the musculoskeletal system, as well as the development of disorders in the work of adjacent areas of the head and neck, which will improve the quality of life of the individual and the population as a whole. Prospects for further research are formulated, which can be the basis for predicting the risk of developing TMJ pathology and the development of a complex of dental and diseases.

Subject. The relevance of the study is associated with the widespread prevalence of diseases of the temporomandibular joint and masticatory muscles. The large amount and inconsistency of literature data, the lack of generally accepted terminology and diagnostic criteria, and the variety of treatment methods proposed by various authors lead to difficulties in the choice of treatment tactics encountered by the dentist in everyday practice in treating patients with temporomandibular joint pathology. The goal is to study the available literature data on the prevalence and structure of clinical manifestations of functional disorders of the temporomandibular joint. Methodology. The study was conducted on the basis of a search and study of scientific publications on the epidemiology of clinical manifestations of functional disorders of the temporomandibular joint in the databases PubMed, eLibrary, Scopus, Web of Sciens, Medline. The selection of materials was carried out by keywords. Results. The review presents the scientific data of various authors on the epidemiology of the clinical manifestations of dysfunctional disorders of the temporomandibular joint. The most characteristic objective signs of the temporomandibular joint dysfunction syndrome are: “noise” phenomena in the joint during movements of the lower jaw, pain during palpation of the masticatory muscles, restriction of opening of the mouth, deviation during opening of the mouth, bruxomania, displaced position of the lower jaw relative to the upper (transverse, medial distal), the presence of otological symptoms (pain and / or a feeling of stuffiness in the ears), a burning sensation, tingling, tingling, or pain in the tongue. Conclusions. A study of the literature over the past 15 years has revealed a wide variation in the prevalence of clinical manifestations of functional disorders of the temporomandibular joint, which does not allow an unambiguous conclusion about the epidemiology of its dysfunction.

A literature review was conducted on an urgent problem of dentistry – the influence of lifestyle on the development and course of inflammatory periodontal diseases with an assessment of the risk of malignant neoplasms. Purpose of the study. Based on the review of modern scientific literature for the period since 2014, to study the problem of the influence of lifestyle on the development and course of inflammatory periodontal diseases and to assess the risk of malignant neoplasms. Methodology. The data of special literature were studied using scientific search library databases: PubMed Central, Elibrary. The search for original scientific publications was carried out by keywords. This review includes an analysis of 40 scientific sources. Results and conclusions. The literature review systematizes modern scientific data on the effect of nicotine and alcohol dependence on the development and course of inflammatory periodontal diseases, the development of periodontitis and gingivitis in patients with a predominance of foods containing glucose and sweeteners in the diet, the effect of ethanol on connective and epithelial tissue, on a decrease in local immunity. The review also presents current data on food products, vitamins and trace elements that reduce and increase the risk of developing inflammatory periodontal diseases, the study of implant integration and the development of complications in the postoperative period in patients with nicotine and alcohol dependence, the problem of preserving teeth in people who use psychoactive substances, the risk of developing malignant neoplasms in the maxillofacial region, the influence of narcotic drugs on the immune system and the condition of periodontal tissues, personalization of patients, creating new diagnostic and treatment strategies for patients with addictions.

Subject. The study of the sanitary culture of rural population is an information and analytic base for the development and implementation of activities concerning the primary prevention of dental diseases on the territories of southern rural areas of Tyumen region. The aim is to estimate the social and hygienic level of skills in the population of Jurga district of Tyumen region. Materials and methods. The investigations were carried out using expeditionary and exploratory method. 200 men living in Jurga district took part in the questionnaire. The standardized questionnaire regarding the oral health developed by WHO experts (2013) was used. All men were divided according to the gender and age [at the age of 12 (n=69), at the age of 15(n=31), at the age of 35-44 (n=67), at the age of 65 and older (n=33)]. According to the data received the portrait concerning social and hygienic skills was made up for each age group. The results were processed using analytic program «Vortex 10.7.3». Results. The analysis of the received data revealed the low level of social and hygienic skills in the population of all aged groups living in Yurga district. The conducted medical and sociological questionnaire of population showed that the significant part of the population does not have knowledge of the choice of hygienic objects as well as the insignificant volume of skills of the individual oral hygiene. Also they do not have the necessity of carrying out preventive measures, dynamic check up of the oral health. Besides, the education of the population also plays a great role in the prevention of dental diseases. The tendency to the high motivation of carrying out the preventive measures was revealed in the persons having high education.
