The article analyzes the biomechanical aspects of the load pin design in different conditions of its operation; It shows the critical situation, causing a voltage limiting tooth root.

The article discusses the evaluation of the effect of exogenous glucosamine hydrochloride and chondroitin sulfate on biochemical parameters of blood serum and periodontal tissues during experimental inflammation. Experimental model of gingivitis were formed at 40 white Wistar rats, were formed: the control and main groups, further investigated the periodontium in 20 intact animals. Research total proteolytic activity in the blood serum of rats with experimental evidence of periodontal inflammation enhancing its performance throughout the experiment as compared with the data obtained in intact animals. In experimental gingivitis with marked intensification of proteolytic activation of lysosomal enzyme acid phosphatase in the serum and in the periodontal tissue homogenates, indicating that damage and destruction of periodontal membrane cells. Installed, that the application of exogenous glucosamine hydrochloride and chondroitin sulfate in experimental inflammation of the periodontal tissues leads to a normalization of the main markers of inflammation, including General proteolytic activity and acid phosphatase activity, demonstrating anti-inflammatory and parodontopathies effect.

The results of the determination of the strength properties of individual zirconium zirconium inoculum inserts in different parts of the dentition at different occlusal load angle values are given in the article. The greatest strength was demonstrated by molars at a loading angle of 0°, the smallest incisors, at a loading angle of 30°.

On the basis of carried out complex investigations has been estimated that between tabaccomakers observes disturbance of biting analizators as increasing, decreasing and changing of biting sensitivity. For this disturbance may serve integral indications of negative influence of productive factors of tabaccomakers to the organism of who are working.

Research results of clinical aspects of dentition deformation in cases with included dental defects and different structures of maxillofacial region are presented in the article. Toque and angulation teeth abnormality on the side of the dentition defect, resizing of the dental row, changing of the occlusal plane inclination, dentition ratio abnormality all of these are the main symptoms. The combination of dental row deformation sings depends on the structure type of maxillofacial region. The orthodontic treatment tactics of patients with dentition deformation and included dental defects are justified subject to the comprehensive rehabilitation.

Healthcare - an industry that affects every citizen of the country, and on the most sensitive issues - health and often life. The health system provides the country’s national security, without healthy citizens, it is impossible to increase their production and provide defenses. Health the last ten years intensively reorganized. The article presents data reflecting the results of the author’s position as to the assumptions that led to the need of reforming the health care system in the Russian Federation.

Work activity of a dentist is systematically affected by negative productive factors while severity of vertebroneurological diseases is directly proportional to work experience and work intensiveness of a doctor as well as noncompliance with ergonomics rules that leads to decrease of dentist working capacity in the period of the highest qualification level and extensive clinical experience of the specialists. Therefore the control over implementation of labor protection instructions and ergonomics recommendations for women dentists in pregnancy as well as implementation of certain recommendations in everyday practice would stimulate improvement of their competitiveness and dental industry development.
