COMPARATIVE ANALYSIS OF STUDYING THE INFLUENCE OF IONIZED SILVER SOLUTION DURING IRRIGATION OF THE OPERATING FIELD WITH DIFFICULT EXTRACTION OF TEETH ON THE LOWER JAW IN DYNAMICS
Antonyan A.B., Kharitonov D.Y., Petrosyan A.E.
Abstract
In the daily practice of a dental surgeon, a doctor is often faced with the need to carry out surgical interventions for complex tooth extraction in the lower jaw. These surgeries are performed for various reasons, for example, for chronic periodontitis, periodontal diseases, teething diseases, orthodontic indications. All stages of surgical intervention for tooth extraction are accompanied by the risks of complications of various origins. In order to prevent all complications, there are many ways and techniques of both the extraction operation itself and drugs that reduce the risks of such. However, the relevance of the study of this issue does not lose its importance, since every day doctors also face the problems of complications of inflammatory genesis in the post-extraction period.

ELECTROCHEMICAL CHARACTERISTICS OF THE SYSTEM "DENTAL IMPLANT - PROSTHESIS"
Shashmurina V.R.
Abstract
The development of implantology requires studying the urgent problem of electrochemical compatibility of construction materials and implants in order to prevent pathological processes caused by galvanism in the oral cavity. The electrochemical compatibility of a titanium implant and materials of dental prostheses in vitro was studied by measuring the electrode potentials of alloys in a stationary state, interacting through layer of a model solution of different thickness. It was experimentally established that in the system "metal alloy prosthesis - model solution (artificial oral fluid) - titanium implant" galvanic currents arise, the magnitude and direction of which depend on the type of metal alloy. For the manufacture of dentures on titanium implants it is recommended to use chromium and chromium-nickel alloys and limit the use of stainless steel and gold-platinum alloys.

ASSESSMENT OF RESIDUAL MICROFLORA IN PATIENTS WITH INFLAMMATORY DISEASES OF MAXILLOFACIAL REGION
Andreev A.A., Stepanov I.V., Khryachkov V.I., Khodorkovsky M.M., Podoprigora A.V., Moiseeva N.S.
Abstract
In the practical work of the maxillofacial surgeon, it is necessary to take into account the presence of a pathogenic microflora with a small number of colony-forming units, since when the reactivity of the body decreases, they will cause local inflammatory reactions, which leads to a deterioration in microcirculation and trophy of neighboring tissues. The aim of the study was to assess residual microflora in patients with inflammatory diseases of the maxillofacial region. In 43 patients surgically treated with the purulent focus, oral flora surrounding the purulent focus of tissues and the wound contents directly were examined. In most cases, a combined microbiological flora has been isolated. The difference in the amount of CFU/ml determines the course of the local inflammatory reaction, as well as the state of microcirculation. The latter factors play a large role in the successful course of a smooth postoperative period.

ASSESSMENT OF BIOLOGICAL COMPATIBILITY OF METHYL ACRYLIC POLYMERS IN CORRECTION OF PARTIAL SECONDARY ADENTIA AND CONCOMITANT PATHOLOGY OF DIGESTIVE ORGANS
Zukanova E.A., Mikheev A.A., Morozov A.N., Sushchenko A.V., Pdoprigora A.V., Popov P.A.
Abstract
The article presents the data of an original study on the improvement of orthopedic treatment of partial secondary adentia in patients with concomitant chronic pathology of the gastrointestinal tract by the method of removable plate prosthetics. For this purpose, a comparative analysis of three alternative to each other preparations of methyl acrylic polymer for the manufacture of bases of prostheses was made: 1) «GC», 2) «3M-Espe», 3) «Ftorax». A scientific assumption has been formulated that the choice of a specific polymer preparation (within the comparison base) will lead to a fundamental decrease in the level of local inflammatory changes in the mucous membrane of the prosthetic bed. In three independent groups of patients, using the compared preparations of methyl acrylic polymer, a cytological assessment of local inflammatory changes was made. For this, the parameters of neutrophils were studied (show a picture of subacute and chronic inflammation) and the level of fibroblastic infiltration (shows a picture of chronic inflammation) within the mucous membrane of the prosthetic bed. After the implementation of the study, it was found that the most positive results are shown by the polymer «GC», the least positive - by the polymer «Ftorax», the polymer «3M-Espe» occupies an «intermediate position». The results obtained have a high level of statistical significance, which makes it possible to recommend them for consideration for use in the practice of orthopedic dentistry.

THE PROBLEM OF FRONTAL TEETH ROOT CANALS CLASSIFICATION: A RATIONAL DECISION BASED ON MULTI-FACTOR ANALYSIS OF ADVANCED DIAGNOSTIC VISUALIZATION DATA
Ovsyannikova N.A., Mikheeva O.I., Morozov A.N., Popov P.A.
Abstract
The article presents the data of the original research on the development of the optimal ergonomic classification of the root canals of the frontal teeth. The classification system was created on the basis of multivariate analysis of a significant statistical data set (400 research objects). Empirical data on root canal morphology were obtained using the currently most accurate diagnostic imaging technique - cone-beam computed tomography (CBCT) instead of traditional radiography. The solution to the problem of classification and objectification of research results is based on the use of variation statistics and cluster analysis. When classifying the morphological characteristics of the root canals of the teeth of the frontal group, their basic classifying categories were confirmed - the type of tooth, maxillary or mandibular affiliation, the number of root canals, their diameter and separation. In addition, in the course of the study, 11 most common «additional morphological singularitys» of the structure of the canal system were typified. Due to the procedure of clustering the morphological characteristics of the channels, their statistically stable combinations were determined, which made it possible to identify 16 classification groups. The verification of the developed classification model has shown its high efficiency - due to its use, it became possible to significantly facilitate the choice of endodontic programs in a specific clinical situation and improve the subsequent results of the planned treatment.

IMPROVING THE DIAGNOSIS OF PERIODONTAL DISEASES USING A MODERN RESEARCH METHOD
Postnikov M.A., Tkach T.M., Lyamin A.V., Vinnik A.V., Vinnik S.V.
Abstract
In modern times, inflammatory periodontal diseases remain in the leading place among the pathology of organs and tissues of the oral cavity. The percentage of the total population suffering from chronic inflammatory diseases of periodontal tissues ranges from 70 to 98%. Intact periodontium occurs in 2-10% of the population of Russia. In 52% of the population, inflammatory phenomena in the periodontal tissues of an initial character are noted, in 24% there are manifestations of moderate and 14% of severe [1]. For the diagnosis and the appointment of personalized treatment, the most complete examination of the patient is necessary. To develop optimal treatment tactics, patients undergo laboratory and other types of examinations of the contents of the gingival groove and / or periodontal pocket. The combination of diagnostic methods allows examining the patient to identify the etiological agent, formulate the correct diagnosis and prescribe personalized treatment. In the study, we evaluated the titer of aerobic and anaerobic microorganisms in samples, in larger quantities in a clinically significant titer. There are a number of different instruments for taking the contents of the gingival groove and / or periodontal pocket, but they all have many drawbacks that complicate the inoculation of the material, degrade the quality of the samples obtained and distort the research results. Taking into account the advantages and disadvantages of existing instruments for taking the contents of the gingival groove and / or periodontal pocket, we have developed an instrument for collecting the contents of the periodontal pocket for the purpose of microbiological examination.

Azarova O.A., Pankova S.N., Lepekhina L.I., Lepekhina O.A.
Abstract
The number of identified cancer diseases at the dental appointment is constantly increasing. Dentistry as a branch of medicine works with problems of the oral cavity, which as an anatomical area is available for examination and instrumental examination using basic and additional methods. A doctor who has the concept of “on-alertness” will be able to avoid trauma to the soft tissues of the oral cavity in his work. A doctor who has the concept of “oncological diagnosis” will not miss pathology, he will be able to conduct differential diagnosis, a course of therapeutic treatment in a strictly defined time frame and, if necessary, refer the patient to oncologist. The primary care doctor will be able to psychologically correctly inform the patient about serious problems in the oral cavity.
