Abstract
Clinical Center of Stomatology of FMBA of Russia, 123098, Moscow, Russian FederationDental morbidity in childhood is practically not reduced. The effectiveness of preventive measures is great in early childhood, and therefore relevant research on the epidemiology of the prevalence and intensity of caries and gingivitis in children 6-9 years. Surveyed 176 people at the school of Moscow and the indicators of dental disease and treatment needs among schoolchildren 6 to 9 years. In Moscow, the prevalence of caries - 92,0%, periodontal disease - 19,3% with intensity of 1,67±0,03 (CPU) and 0,53±0,03 (CPI), respectively, with satisfactory and good oral hygiene in 81,1% of the surveyed children is high in the period of a change bite. The need for dental treatment in the examined patients has a structure: in the treatment of caries - 32,4%, in the removal of teeth - 15,3%, in professional hygiene - 19,8%, in the preventive sealing of fissures - 34,1%. The total need for dental and periodontal sanitation was 52.8%.

NEED IN PROPHYLACTIC AND TREATMENT OF SCHOOLCHILDREN USING OF INTERNATIONAL CARIES DETECTION AND ASSESSMENT SYSTEM
Ashurov G.G., Mullodzhanov G.E., Yuldoshev Z.S.
Abstract
With using the index of the international caries detection and assessment system organized cariesology examination of 150 детей in the key’s age groups (6, 12, 15, 16-19 years). Herewith examined all surfaces of each teeth. For estimation of the depth of the carious defeat used the following codes: 0 - health surface of the teeth; 1 - an initial changes of enamel (visible after long drying by air); 2 - an evident visible changes of enamel; 3 - a carious cavity within enamel; 4 - subjecting to darkening shade in dentine; 5 - an evident cavity within dentine; 6 - an extensive cavity in dentine, possible involvement of the pulp. In undertaking given of medical-preventive action of cariesology nature need 96.9%, 99.3%, 95.9% and 98.4% schoolchildren accordingly in the age groups of 6, 12, 15 and 16-19 years. Results of the study have shown high need for invasive treatment of carious cavities amongst examined person. Using the criterion of the the index of the international caries detection and assessment system allows to conduct the early diagnostics of the carious defeats and prevent progressing initial caries in stage, requiring uninvasive of the treatment.

CLINICAL AND FORENSIC ASPECTS OF ASSESSING ADVERSE OUTCOMES IN SURGICAL DENTISTRY IN THE TREATMENT OF MANDIBULAR FRACTURES
Butenko O.G., Topolnitsky O.Z., Romodanovsky P.O.
Abstract
There were the data adduced concerning the rate and character of the physician mistakes and complications while surgical treatment of the mandibula fractures. The main causes of the physician mistakes occurrence and the ways of their prophylaxis were determined. There was established, that the physician mistakes rate while performing mandibular ostheosynthesis constitutes 32.8%, in 6.8% of the observations the negative outcomes elimination demands the essential prolongation of the treatment period, reoperations performance of the dental malocclusion correction, using orthopedic or orthodontic methods. The majority of mistakes, afforded intraoperatively, constitute the outcome of nonadequate preoperative diagnosis and planning of the treatment measures. There are discussed the possibilities of application of modern methods of computeric diagnosis and virtual modeling of surgical interventions for minimization of intraoperative risk and reduction of the mistakes and complications rate of the mandibular fractures surgical treatment.

PERSONIFIED BIOMECHANICS OF EDENTULOUS JAW WITH RESTORATION ON THE SCHEME OF “ALL-ON-4” AND WITH PARALLEL IMPLANTS
Dashevskiy I.N., Gribov D.A., Olesova V.N.
Abstract
The technology of patient-specific computer planning of the restoration process of the edentulous mandible dentition using dental implants is considered. A model of the jaw and distribution of elastic modules by its volume are reconstructed from a computer tomogram. The model is supplemented with virtual implants and a model of the prosthetic structure and is passed on to the finite element complex, where the loading and supporting conditions are specified. Biomechanical analysis and comparison of two implant placement schemes (“All-on-4” and in parallel implants) is carried out for two types of loading that model biting and chewing.

OPTIMIZATION OF THE ROUTINE WORK OF A DENTIST QUALITY CONTROL PHOTOCOMPOSITE RESTORATIONS OF ANTERIOR TEETH
Lobach O.I., Lapina N.V., Skorikova L.A., Gayvoronskaya T.V., Kochurova E.V., Gavryushova L.V.
Abstract
The aim of the study is to optimize the routine work of a dentist to control the quality of photocomposite restorations of the frontal group of teeth. Materials and methods. 30 people with violation of aesthetics of hard tissues of the anterior group of vital teeth (n = 166) were examined and treated. The quality of the produced restorations was assessed according to the generally accepted Ryge criteria by the classical method and using the “Intraoral optical microscope” [1] immediately after the restoration, 6 and 12 months later. Results and discussion. There were no significant differences in the stability of restorations according to the Ryge criteria when using foreign and domestic composites (p > 0.05). After 6 months, color stability, edge fit and roughness decreased in both cases (p > 0.05). When comparing the restorations immediately after the filling, 6 and 12 months after the Ryge criteria by the classical method of quality assessment and using the “Intraoral optical microscope”, statistically significant (p < 0.05) differences were found in terms of “edge adaptation”, “secondary caries”, “surface roughness”, “change in the color of the edges of the cavity”; at the same time, such criteria as “color matching” and “preservation of anatomical shape” when using both methods had minor differences. Summary. Stability in the quality of the restorations according to the criteria Ryge both photocomposite materials (Estelux NK and Filtek Z550), no significant differences were found. Therefore, the domestic material Estelux NK, taking into account its financial availability can be recommended as a composite of choice in aesthetic dental rehabilitation. To control the results of treatment with the use of restoration photocomposites, it is possible to recommend the generally recognized Ryge criteria with the use of an “Intraoral optical microscope” due to greater objectivity and simplicity in application.

Abstract
The analysis of the prevalence of malignant neoplasms (EIT) on the lips and oral cavity according to the annual report on Russia prepared by the Moscow Oncology research Institute named after P. A. Herzen and the Moscow regional oncologic dispensary. The dynamics of the analysis was carried out for 2011 - 2017 years. The detectability of the lip and oral cavity ZNO in the Moscow region is significant. The incidence of malignant tumors of the oral cavity is more pronounced in comparison with the ZNO lips. The extent of the EIT I-II degree are more characteristic of ZNO lips, and for TESTING of the oral cavity II-III degree. Mortality during the first year after diagnosis was established in every fourth patient with oral HEAT. The prevalence of lip ZNO for the period from 2011 to 2017 decreases, and the ZNO of the oral cavity increases.
