During mechanical debridement of root surface of teeth, it is important to ensure not only the smooth and biocompatible surface, but also make a complete evacuation of removed substrate of periodontal pockets that can be complicated in furcation area. Difficult tool access, complicated instrumentation and lack of complete information about this zone leads to unsatisfactory results of treatment. Therefore, for a full evacuation of microbal biofilm components it is necessary to use manual instruments. Morphometric study of 30 furcations of maxilla teeth allows to form an idea about specificities of this zone. For making correct selection of tools it is necessary to take into consideration the specificity of the treated area, especially furcation.

In the investigation the assessment of the distribution of the elementary composition in the superficial layers of the tooth enamel in the field of erosion was held using XRF analysis. The results showed the increased content of Zn, S, Cl, K and Sr. And its maximum appeared in the middle of the erosion. Besides that in the investigation the assessment of the qualitative changes in the elementary composition of the tooth enamel in the field of erosion was held using XRF analysis. It showed that in the field of erosion the content of phosphorus decreases more intensively in comparison with calcium and, as a result, Са/Р increases.

It is provided a certain range of literary sources, reflecting the adaptation features of ICD, as well as an example of its practical application at the Department of Еndodontics and Сariology of MSUMD while implementing Federal State educational standards of the third generation.

Nanoimpregnation with particles of copper hydroxide-calcium in treatment of dental hyperesthesia (experimental study). Based on the Branstrem's theory of development of dental hyperesthesia, reliable and deeper obturation of dentinal tubules with microscopic particles may most effectively reduce this hyperesthesia. The aim of the study was the experimental validation of methods of nanoimpregnation of hypersensitive dentine with particles of copper hydroxide-calcium. Study results have provided rationalization for the new and the most effective ways to eliminate dental hyperesthesia using electrophoresis or galvanophoresis with copper hydroxide-calcium. Light-optical analysis of teeth revealed the density differences of precipitate of copper sulfide, indicating the differences between the intensity of impregnation of dentine using these two methods of copper hydroxide-calcium application for this purpose.

Dynamics and proportions of proinflammatory and anti-inflammatory cytokines in patients with dental implantation were studied. In 106 patients with dental implants without complications, the study was performed before and after 7-10, 30 days. IL-1β, IL-6, TNF-α, IFN-γ, IL-4, IL-10 were determined in the gingival fluid by solid-phase enzyme immunoassay. A significant increase in the level of TNF-α and IL-10 was observed on day 7-10, and TNF-α at day 30. At 7-10 days after implantation, an imbalance in the ratio of IL-1β / IL-10, TNF-α / IL-4, TNF-α / IL-10 was observed in comparison with the control, the proportion of pro- and anti-inflammatory cytokines was almost normalized on day 30, Only the ratio of TNF-α / IL-10 remained elevated. The enhanced synthesis of pro-inflammatory cytokines was countered by the enhanced synthesis of IL-10, which in our opinion is related to the ability of IL-10 to inhibit the cytotoxic activity that TNF-α exerts.

The results of measuring the depth of penetration of the ultrasonicated bactericidal solution of nanosilver Poviargrol into Dentinal Tubules of the tooth are presented. Investigations were carried out using the method of monochromatic X-ray microtomography with synchrotron radiation source with a critical energy of 7.1 keV. The diffusion indices indicate a deeper penetration of the ultrasonic-activated solution of nanosilver into the dentin in comparison with free penetration. Monochromatic X-ray microtomography with synchrotron radiation source can be an effective method of analyzing the penetration of inorganic drugs into hard tooth tissues.

Saving teeth and maintaining their function are the main objectives of dentistry. Currently, an increasing number of patients are motivated by the fact that dentists have made every effort to save the tooth. Despite notable achievements of world and domestic implantology, endodontic treatment is still important in the treatment of periodontal diseases. The emergence of new tools and equipment has significantly improved the quality of endodontic treatment, but even the use of the microscope in endodontic practice has not reduced the importance of radiological diagnosis and treatment monitoring. The aim of this work is to remove fragments endodontic tool in the root canal by the proposed method.

A research objective was performing treatment and dynamic observation within 12 months of 52 patients at the age of 25-35 years with chronic apikalny periodontitis. The assessment of the dental status was carried out under the WHO recommendation, the radioviziografichesky research with function of determination of optical density of a bone tissue (densitometry), a microbiological research of contents of the root channel, an immunological research with definition of a tsitokinovy profile of oral liquid and an elektroodontodiagnostik (EOD) has been conducted. Complex treatment was carried out according to the scheme developed by us with use of mix of the medicines «Galavit» and «Trapeks-gel» and physiotherapeutic treatment. On the basis of the received these researches, treatment of chronic apikalny periodontitis was effective. As a result we have received restoration of a rezorbirovanny bone tissue at all patients.

In the work on the basis of clinical and functional examination of 120 men of draft age (16-17 years), the frequency of occurrence of temporomandibular joint (TMJ) diseases was studied and the role of temporomandibular arthralgia during the examined pathology was clarified. It is established that the diseases of the TMJ and masticatory muscles in persons of conscript age are often enough, respectively, in 26,7% and 10% of cases, often burdens each other. The pathology of the TMJ in pre-opioids in 31,3% of cases occurs in moderate or severe degree, with temporomandibular arthralgia indicative of the course of the TMJ pathology in moderate or severe form. It is emphasized that when conducting military medical commissions among persons of pre-conscription age for the purpose of putting them on military records, it is necessary to identify in a timely manner conscripts suffering from TMJ and masticatory muscles diseases and direct them to clarify the diagnosis and conduct specialized treatment.

Effective treatment of pulpitis of teeth is an important and urgent problem of modern dentistry. The aim of the work was to evaluate the clinical effectiveness of the bioactive dentin substitute in the treatment of reversible forms of pulpitis. The doctors performed a procedure for direct coating of pulp in 87 teeth in 62 patients. . Most of the teeth in an objective study met all the criteria for success: the restoration was fully preserved (98.8% of the score was «good» and «excellent» according to the specified criteria), postoperative sensitivity was absent in the next (89.3%) and in the long term (95, 2%), the vitality of the teeth was confirmed with a cold test and radiologically (97.6% success).

The article is devoted to the review of possible reactions to the use of sulfite-containing anesthetics and ways to detect and prevent allergic reactions in dental practice. About 7% of all people suffering from bronchial asthma have an increased sensitivity to sulfites. To date, the mechanisms that underlie susceptibility to sulfites remain unclear, although a number of potential mechanisms have been proposed, including genetic predisposition. Undoubtedly, optimal selection of a local anesthetic for patients with weighed allergic anamnesis will require adequate diagnosis of possible drug allergies, joint management of such patients by a dentist and an allergist.
