Aleksandrov M.T., Zubov S.V., Berezinskaya A.S., Kukushkin V.I., Pashkov H.E., Ivanchenko O.N.
Abstract
Applying the Express-method of laser-conversion diagnostics (ACL) conducted experimental and theoretical substantiation of increasing the efficiency of diagnosis and pathogenetic treatment of caries of teeth. For the studied range of action of the laser radiation in the optical range with a wavelength of637 nm (red range of the laser radiation), 532 nm (green range of the laser radiation), 405 nm (blue range of the laser radiation) for effective pathogenetic diagnosis of caries. Investigated the possibility of Raman scattering and fluorescence as the basic components CALS, for example etiology, pathogenesis, stages of clinical course and treatment of tooth decay, as well as in intact and кариозно modified tooth tissue method CALS (fluorescence and Raman scattering). Defined perspective of clinical application.

THE STUDY OF MECHANICAL PROPERTIES OF ADHESIVE SYSTEM WITH A SILVER NANOPARTICULATE FILLER
Bessudnova N.O., Bilenko D.I., Venig S.B.
Abstract
In the present study nanoparticulate silver filler influence on adhesive system mechanical properties has been researched. In the course of laboratory experiments it has been shown that adhesive system mechanical properties are changing in a different manner as soon as silver percentage in adhesive system is increasing. It has been established that 1% silver nanoparticle embedding into adhesive system that is enough to make the material X-Ray-sensitive holds its mechanical properties close to the optimum. Thus, the mechanical properties are enhancing in comparison with those of adhesive system without silver nanoparticles. Research findings point to the opportunity to use nanoparticulate silver as a filler while producing X-ray adhesive systems.

EXPEREMENTAL PREVENTION OF STRESS CHANGES OF TOOTH PULP TISSUES AND PERIODONTIUM WITH NITRIC OXIDE DONOR MOLECULES
Yermak E.Y., Maters T.V., Panina E.V., Ananyina E.V., Rodionova T.I., Zotova I.N.
Abstract
The research results of influence of donors and anzyme blocker NO-synthesis on morphological state of tooth pulp and periodontium tissues at stress influence on laboratory animals. It is revealed, that nitric oxide donor molecule L-arginine is able to limit the development of stress-reaction and decrease quantity of morphofunctional infrigements in periodontium tissues and teeth stump. Enzyme blocker NO-synthesis L-NNA helps to strengthen alternating effects of stress reaction in periodontium tissue and teeth pulp.

BACTERIAL FACTOR AS A MEMBER OF INFECTIOUS AND INFLAMMATORY PROCESSES IN THE ORAL CAVITY
Labis V.V., Bazik'an E.A., Kozlov I.G.
Abstract
Violation of the integrity of the periodontal tissues as in the mechanisms of periodontitis and peri-implantitis, is attributed to immune-mediated diseases. Opening of the TLRs and NLRs receptors enables a new way to consider the pathogenetic aspects of the mechanisms of development of these clinical entities. Interaction of microbial factor with the human body, on the basis of genetic mediation by the immune system in the development of infectious and inflammatory diseases, makes it possible for a new study and interpret the complex symbiotic relationships. The ability to "escape" the oral pathogenic mechanisms of the innate immune system, can lead to diseases in the oral and maxillofacial region.

THE ROLE OF THE IMMUNE SYSTEM IN THE PATHOGENESIS OF REPARATIVE PROCESSES
Labis V.V., Bazikyan E.A., Kozlov I.G.
Abstract
Immunology as implantology, can be attributed to the rapidly growing fields, which is a prerequisite to their further joint development. The role of dendritic cells (cDCs) in the development and regulation of the immune response to the injury of bone tissue, namely BMDCs (dendritic cells in the bone marrow) is just beginning to be studied both in this country and abroad. Becomes relevant new perspective on cell-cell interactions that occur in the collagen-elastin matrix of bone. The search continues for molecular biological markers involved in reparative osteogenesis, and focuses on new aspects of the mechanisms of regeneration, which are of a regulatory nature during reconstructive surgery in the maxillofacial region.

COMPARISON OF OPERATIONAL PROPERTIES OF THE DOMESTIC MATERIAL FOR TEMPORARY NONREMOVABLE DENTURES "ESTERFILL PHOTO" WITH FOREIGN ANALOGUES
Lebedenko I.Y., Goryainova K.E., Pojurovskaja I.J., Aliev A.D.
Abstract
Materials for temporary prostheses different manufacturers have different physical, mechanical properties and aesthetic parameters. In our work we compared the domestic composite material «Esterfill PHOTO» with foreign analogues: «Systemp ®c&b» and «VITA CAD-Temp». A comparison is made between the following parameters: color stability, transparency, water absorption, surface properties and internal structure. According to the results of this research material «Esterfill PHOTO» has the most homogeneous surface. Also, this material showed the best results of the indicators of water absorption and transparency. However, «Esterfill PHOTO» has lower rates of color stability than other tested materials.

CLINICAL AND ELECTROMETRIC ASSESSMENTS OF CHILDREN'S DIRECT RESIN RESTORATIONS AND CERAMIC FILLINGS MADE WITH CEREC 3 ARE THE PURPOSE OF THIS RESEARCH
Kisel'nikova L.P., Koval'chuk M.A., Masterova I.V., Plyukhina T.P., Lebedenko I.Y.
Abstract
60 first permanent molars with “dental caries (K02.1)” (31 by the direct resin restoration and 29 by dental restoration with CEREC) were restored among 41 patients. The assessment of the quality of the restoration/filling marginal fit to the dentine was based on the results of the electrometric research (Geosoft DentEst equipment) and on the data shown on the G. Ryge scale in 10 minutes, in 3 months and in 6 months after the restoration. 6 months of the research showed that all restoration were clinically and electrometrically admitted as excellent and acceptable. None of the restorations was received a “C” mark. After 3 months there was no statistically significant difference in the results of the restoration ’s view (inlay or filling) and of their localization (I and II according to Black).

THE TREATMENT OF PATIENTS WITH ACUTE ODONTOGENIC OSTEOMYELITIS, COMPLICATED PHLEGMONS
Medvedev Y.A., Gunter V.E., Kharnas P.S.
Abstract
There are results of treatment of patients with acute odontogenic osteomyelitis, complicated phlegmons in the article. During the observation the separation of patients on group depending on prevalence of purulent- inflammatory process, methods of treatment — traditional or using of nickelid titanium shape-memory retractors. In patients were treated with shape-memory retractors. There was a normalization of temperature on average 4 ± 1 days earlier than in the control group, granulation appeared on average 4 ± 2 days earlier, which contributed to more rapid imposition of secondary joints and curing of the patients respectively.

OPTIMIZATION OF SURGICAL TREATMENT OF PATIENTS WITH MANDIBULAR FRACTURES WITHIN THE DENTITION AND BONE DEFECTS WITH THE HELP OF THE MATERIAL “COLLOST”
Medvedev Y.A., Serova N.S., E.Ju. D.Y., Milyukova D.Y.
Abstract
Issue of filling bone defects remain unresolved as the planned and emergency maxillofacial surgery and dentistry. In the case when the hole after tooth removal heals under the clot may develop chronic inflammatory diseases of the message with the oral cavity. In our study, under the supervision within 1 year were patients with mandibular fractures within the dentition. All the patients were divided into 2 equal groups. In the main group was filling defect bone material "Collost" unlike the comparison group, in which patients were treated surgically without implantation material in the area of bone defect. The results of our study indicate a reduction of terms of osteoreparative processes and rehabilitation of patients using material "Collost".

DIAGNOSIS METHODS EVOLUTION OF ODONTOGENIC RUPTURED MAXILLARY SINUSITIS
Haritonov J.M., Frolov I.S.
Abstract
Odontogenic ruptured maxillary sinusitis has been an up-to-date problem in the surgical odontology and maxillofacial surgery for long time. Despite the fact that this pathology is known and described well in medical sources the number of those who suffer from this disease is increasing. It is obvious that timely and proper diagnosis is the guarantee of effective treatment. The authors of the article made an attempt to study cases of odontogenic ruptured maxillary sinusitis in details, including clinical, laboratory and instrumental methods of examination. Specific attention was given for such newest and informative methods as computer tomography, magnetic resonance imaging and also endoscopic, histologic, bacillary diagnosis etc. The authors point out advantages and disadvantages of these methods emphasizing the necessity of team approach for diagnostication of odontogenic ruptured maxillary sinusitis.
