Olesova V.N., Khafizov R.G., Shmatov K.V., Ivanov A.S., Martynov D.V.
Abstract
The relevance of the use of superelastic titanium alloys in medicine is due to biomechanical advantages when interacting with the tissues of the body. To date, such an alloy is known - titanium nickelide, but the high content of nickel limits its use. Superelastic alloys of titanium (titanium-niobium-zirconium and titanium-niobium-tantalum) are more favorable in comparison with titanium for dental implants due to physico-mechanical properties closer to bone tissue. Animal morphological studies of the biocompatibility of these alloys in comparison with titanium have been carried out. Control of the interaction with the bone tissue of titanium alloy samples was 30 and 90 days; The method of investigation is scanning electron microscopy and microprobe element analysis of tissue along the boundary with titanium alloys. The proximity of the morphological pattern and elemental composition of bone tissue along the border with titanium and superelastic alloys of titanium is shown, both at a control period of 30 days (in contact with alloys, a poorly mineralized connective tissue is found) and under control of 90 days (the border with titanium alloys is covered with mineralized bone tissue, similar in composition to the surrounding bone tissue). based on niobium with bone tissue.

MORPHOLOGICAL STRUCTURE OF ENAMY, DENTINE OF TEETH AND COMPOSITE FORMING MATERIALS IN VITRO
Kolodkina V.I., Arutyunov A.V.
Abstract
Solving the problem of increasing the effectiveness of treatment of diseases of hard tooth tissues is an urgent task not only for the dental community of doctors, but for dentistry in general. Provision of edge tightness and high adhesive bond of copolytic material with enamel and dentin to prevent the occurrence of micro-permeability of restoration for toxic agents and subsequent inflammation of pulp is one of the most urgent problems of therapeutic dentistry. Universal microhybrid composites used for sealing all groups of teeth were created in the last century, however, a number of important problems remain unresolved until now. The purpose of this study was to assess the morphological structure of the enamel and dentin of the teeth before and after using restorative sealing materials with and without sealant coating. The data obtained as a result of the research allows us to estimate from the scientific point of view the changes in the micro-morphological structure of enamel and dentin at the points of contact with the composite material, accompanied by a decrease in the microhardness of the dentine on the background of unsatisfactory oral hygiene, increased consumption of soft and carbohydrate-rich foods, salivary capacity, as well as direct exposure of microorganisms and products of their vital activity to hard dental tissues.

Kalinina A.N., Lasko I.S., Tsarev V.N., Olesov E.E., Stepanov A.F., Glazkova E.V., Olesova V.N.
Abstract
The article presents the results of a microbiological experiment to study the sensitivity of periodontal pathogens to coniferous polyprenols in the preparation of “Solagift”. The optica density of clinical isolates Streptococcus constellatus; Staphylococcus aureus; Fusobacterium nucleatum; Aggregatibacter actinomycetemcomitans during cultivation with the addition of polyprenol concentrate 1:5 was measured during 3-7 days. Comparison criteria: the change in the phase of adaptation (lag-phase), the phase change of geometric growth, the amplitude of the peak phase of geometric growth, the duration of the stationary phase, the period of the withering away of culture. In comparison with the parameters of periodontal pathogens in the control, the presence of coniferous polyprenols led to a significant decrease in the activity of all microbes according to all criteria, especially Staphylococcus aureus, whose growth was completely suppressed.

COMPARATIVE ANALYSIS OF DENTAL DISEASES AND ANTIOXIDANT DEFENSE OF MOUTH LIQUID IN CHILDREN FROM KRASNODAR HAVING CONGENITAL CLEFTS OF LIP AND/OR PALATE AND NEUROPSYCHIATRIC DISORDERS
Gulenko O.V., Volobuev V.V., Vasiliev Y.A., Gracheva A.S., Udina I.G.
Abstract
The degree of antioxidant defense of mouth liquid is studied in children with cleft lip and/or palate (N=46) and in children with neuropsychiatric disorders (N=76) in connection with development of dental diseases. Control group is formed by somatically healthy children (N=60). Inspected children were subdivided into two subgroups dependant on their age: from 8 to 12 years (mixed bite) and from 13 to 15 years (permanent bite). All children were on clinical account in children dental office clinic of Kubanskii State Medical University and constantly lived in Krasnodar. In children with defects of maxillofacial area and with neuropsychiatric disorders in comparison with control, reduced indices of hygiene of mouth cavity, higher indices of distribution and intensity of caries, more heavy flow of periodontal diseases and increase of indices of «oxidative stress» in mouth cavity were observed. Obtained results evidence the display of «oxidative stress» on a background of low level of hygiene in two studied children groups with pathology, which by no means support the development of dental diseases (caries and periodontal diseases), and might be used in practical health protection for the prognosis of the flow of dental diseases.

BIOLOGY OF THE ORAL CAVITY IN CHILDREN LIVING IN THE CITY OF CHIRCHIK
Khaidarov A.M., Mukhamedov I.M., Bekpolotov S.K.
Abstract
The study of microbiological and immunological parameters of the oral cavity among children living in the industrial city of Chirchik, the total number of anaerobes, aerobes, phagocytic activity of neutrophils, the level of lysozyme and the immunoglobulin A secretion fraction of the secretory fraction (sIgA) has been studied. To address this goal, we conducted microbiological and immunological studies in 57 children living in the town of Chirchik. All these children, depending on their age, were divided into 3 groups: Group 1 included 17 children aged 6-7 years. Group 2 consisted of 25 children aged 8-12 years. The third group consisted of 15 children aged 13-15. In children aged 6-7 years, it can be noted that the total number of the optional group of microbes is higher than in anaerobic. In this case, the quantitative indicators of the lactobacillus are especially affected among the anaerobes, so their number is Lg. 2.10 ± 0.1 cfu /ml. Alarming in this group of children is the sowing of pathogenic strains of staphylococcus. The remaining groups of microbes, although there are minor changes, but they are unreliable. At children in the age of 2 and 3 group the flora of the oral cavity in many respects stands close to normal indices. Although it should be noted a significant increase in the number of streptococci, especially strains of Str. mutans and mitis. In children in the age group 6-7 years, almost all indicators show immunodeficiency, so the lysozyme titer was 14 ± 0.41 mg /%, it was normally 19.180 ± 0.60 mg/%, the index of phagocytosis was 48.4 ± 1.45% significantly lower than the control indices, the level of secretory immunoglobulin of class A (sIgA) was 1.7 ± 0.1 g/l, which is much lower than normal values. It is interesting to note that in children older than 8-12 and 13-15 years, these indicators have improved significantly, although it should be noted that their immunodeficiency has worsened, only in terms of the fraction of secretory immunoglobulin A (sIgA). From the above, it follows: 1. According to the sanitary and hygienic and microbiological studies carried out, it is possible to state that the city of Chirchik is an ecologically unfavorable region. 2. The study of oral micro-ecology in children in Chirchik made it possible to establish that in children in the age group 6-7 years the most pronounced are dysbiotic conditions, the main feature of which is the decrease in the amount of lactobacillus, but the increase in the number of staphylococci and fungi of the genus Candida 3. When studying the local factors of oral protection in children living in Chirchik in the age aspect, it was found that immunodeficiency states are most pronounced in children of the I group. 4. The study of the state of colonization resistance of microbes in children living in the city of Chirchik established that the most pronounced violations in these issues were noted in the children of group I.

ANALYSIS OF LABOR AND MATERIAL COSTS IN ORTHOPEDIC TREATMENT OF PATIENTS WITH DENSE OF DENTIST SERIES
Novozemtseva T.N., Zaslavskij R.S., Olesov E.E., Morozov D.I., Glazkova E.V.
Abstract
The article presents the results of the phased timing of the implantation and the production of a permanent prosthesis on implants with complete absence of teeth. The results of the economic calculation of the cost price of prosthetics on implants are given in view of labor costs, material costs, wages and other expenses. The labor intensity and cost of the implantation and prosthesis manufacturing operation were determined, in the amount of 18.8 hours and 98.5 thousand rubles, respectively. In the structure of labor, prosthetics on implants with complete absence of teeth, the labor of the surgeon, orthopedist, dental technician and the operation of technological equipment without the participation of the operator are approximately uniform. In the structure of the cost of prosthetics on implants up to 70.0% is occupied by material costs (cost of implants and components, alloys and ceramics); The salaries of medical personnel and support staff are 22.0%. The discrepancy between the calculated cost price of prosthetics on implants and the higher prices for such prosthetics existing in clinics is due to the need to purchase new equipment and materials, as well as the need to pay higher wages to qualified dentists and dental technicians in comparison with the minimum salary under the Presidential Decrees of May.

GENERAL AND SPECIFIC CASES OF HEMOSTASIS IN RECONSTRUCTIVE SURGERY OF ORAL CAVITY
Kirsanova N.M., Lomakin M.V., Soloshchanskii I.I.
Abstract
In the present article the general and specific cases of hemostasis, in relation to reconstructive surgery of oral cavity, development of which helps to expand the recommendation of dental implants treatment, were systemized and presented for discussion. Secondary healing is the integral condition of successful recovery of organotypical bones and soft tissues volumes in the process of reconstructive surgery. In case of unsatisfactory intraoperative hemostasis the emergence of hematoma of pathological hemorrhagic substratum is possible. It will negatively influence the wound process as secondary healing and, as a result of, will lead to compromising or negative outcome of reconstruction. By this, the relevance of the development of controlled hemostasis methods at reconstructive surgery and dental implantation aiming at increasing clinical and predictive efficiency of the current treatment is determined.
