Alexandrov M.T., Dmitrieva E.F., Akhmedov A.N., Artemova O.A., Potrivailo A., Prikule D.V.
Abstract
The aim of the study is to study the state of mineralization of various anatomical and topraphic zones of teeth for different functiona I groups and to justify its clinical feasibility. In a preclinical in vitro study on 20 model test objects of teeth (incisors, canines, premolars and painters), removed according to clinical indications, Raman-fluorescent study of the degree of mineralization of various anatomical and topographic zones of the tooth in different functional groups of teeth was carried out. Used APC Inspector M with a wavelength of532 nm probing radiation. The advantages of Raman fluorescence spectroscopy for determining the degree of mineralization of hard tooth tissues are objectivity (digital technology), expressiveness, non-invasiveness, simple and non-destructive control of the degree of mineralization/remineralization of hard tooth tissues, the ability to document and store information. In th e course of the study, a qualitative and quantitative analysis of the mineralization of various anatomical and topraphic zones of teeth for different functional groups of teeth was carried out. High sensitivity and reproducibility of the method allowed to reveal significant differences in mineralization of tooth enamel in the area of the cutting edge, equator and neck of the tooth. It is shown that these differences are manifested in other functional groups of teeth (p < 0.05).

Tarasenko S.V., Shehter A.B., Istranova E.V., Morozova E.A., Blagushina N.A.
Abstract
The aim is to increase the efficiency of surgical treatment of dental patients with the use of bioresorbable collagen membranes to close postoperative wound defects of the oral mucous membrane. Material and methods. The experimental model was created on 18 laboratory rabbits. The animals were divided into 3 groups: in the control group the healing of the mucous membrane defect on the hard palate was carried out by secondary tissue tension, in the research groups - under the xenopericardium membrane (1) and collagen membrane (2). The morphological study was based on biopsy of all animals' mucous membranes of the hard palate. Microvolume slices 4-5 microns thick were examined on a light microscope. Results. The results testify to the formation of granulation tissue an d epithelization of defects both in the research groups and in the control group. When using collagen materials, a noticeable activatio n of the wound process, shortening of epithelialization were found. A certain advantage of pericardium in activation of wound repair was noted. Conclusion. Application of collagen membranes can be recommended as a method of choice at closing of postoperative defects of the oral mucous membrane after clinical studies.

Sashkina T.I., Abdullayeva A.I., Mirzekhanova E.P., Pustovaya E.P., Faskhutdinov D.K., Zaichenko O.V., Saldusova I.V.
Abstract
In the experimental study, the penetrating power of dental temporary filling materials Cresofen, Eugenol, Cresodent, Calasept was analyzed. The assessment was made by studying the diffusion of colored solutions of drugs. As a dye used jodoin. It was revealed tha t preparations for temporary filling had different penetrating ability. The greatest penetrating power in the tooth tissue from the studied antiseptic solutions has Cresophen, which penetrates to the entire depth of the tooth tissues after 3 days after application, the intermediate value was shown by Eugenol and Cresodent, which penetrated the cervical and apical regions after 7 days, and Calasept had minimal penetrating properties. These data should be taken into account when planning treatment activities.

Kudasova E.O., Kagramanova N.I., Kochurova E.V., Gavrushova L.V., Nikolenko V.N., Kochurov V.A.
Abstract
Objective. The chewing group of teeth is intended for equally crusher of food and forming food lump. This group is presented by two kinds of teeth: premolars and molars, and more often affected by caries, because a lot of retention zones are contribute to the active delay of plaque and the appearance of carious cavities. It is happening before 18 years. In the absence of these teeth or badly damaged of the crown part, food is chewed badly and as a result, stomach contain extremely large pieces. But its size is impossible for physiological digestion by the gastrointestinal tract and as a consequence the occurrence of gastrointestinal diseases. According to modern data, to work with lesions of hard tissues of the teeth, namely the chewing group of teeth, it is advisable to use composite light-curing microhybrid materials, which are characterized by particles close to the spherical shape. The aim of this study is determination of the possibility using a budgetary aesthetic composite for restorative restoration of the masticatory group of teeth in patients with a burdened anamnesis. Material and methodology. Was examined 22 people with aesthetic and anatomical disorders of the vestibular and occlusal surface of the hard tissues of the chewing group of teeth (n=154), followed by their recovery. The stability of filling materials was assessed according to Ryge-criteria: color coincidence, discoloration of the marginal segment, marginal adaptation, anatomical shape integrity, restoration surface, secondary caries. Results. Clinical and dental examination showed all the above violations of existing restorations (according to Ryge classification) in patients before restoration manipulations. After 1 week after the restoration, the examination showed that both groups of composites completely restore the anatomical and aesthetic chewing group of teeth and meet all the criteria. After 3 months, the assessmen t of the restoration by the composite of group A and group B did not reveal evidence of secondary caries on the perimeter of the restorations. Clinical and dental examination after 6 months showed minor changes in the restorations of composites of both groups in assessing the stability of color (90.9% and 83.3% in groups A and B) and the stability of surface polishing (89.6% and 81.8%, respectively). Discussion. The main signs of the restoration, which are undergoing changes, are discoloration, as well as the preservation of the smoothness of the surface regardless of the cost and branding of the base material.

NON-CARIOUS DENTAL LESIONS IN TYPE 2 DIABETES
Prisyazhnyuk O.V., Iordanishvili A.K.
Abstract
The article presents an analysis of the results of a study of the incidence of non-carious tooth lesions in adults with type 2 diabetes, including when they were under dynamic observation by a dentist for 2.5-3 years. It was found that in patients with type 2 diabetes mellitus non-carious lesions of the teeth (49.51%) were significantly more likely to occur than in people in the control group (29.13%). At the same time, it has been shown that in people with type 2 diabetes, a significant improvement in dental health can be achieved due to their being under dynamic supervision by a dentist with a 2-time visit during the year. This allows to reduce the incidence of non-carious tooth damage in type 2 diabetes mellitus by 17.7%, mainly due to the constantly implemented secondary and tertiary dental prophylaxis, rational and competent use of individual oral care products by patients, and also due to dental orthopedic treatment.

Abstract
The aim of the study was to increase the effectiveness of treatment of facial hemangiomas in children because of the usage of non-selective beta-blocker - propranolol in complex treatment. Materials and methods of research. 18 children under the age of 1 year with maxillofacial hemangiomas were observed. Localized hemangioma was observed in 38.8% (n=7). In 44.4% (n=8) hemangiomas occupied 2-3 adjacent anatomical areas. In 16.8% (n=3) hemangioma occupied more than 3 anatomical areas. For drug therapy of facial hemangiomas in children, non-selective beta - blockers - «Propranolol»were used. Results. The minimum course of treatment was 6 months, the average - 9 months, the maximum - 13. Treatment was completed in 11 (61.1%) children, 4 of them (22.2%) had involution of education. 2 (11.1%) were operated after a course of therapy of betablockers. 5 (27.8%), after 12 months of photothermolysis. Another 5 (27.8%) continue to receive drug therapy with non-selective beta-blockers to date. there is a positive dynamics, consisting in persistent degradation of tumor volume. All children had a significan t decrease in the area and volume of hemangioma. Summary. Localization of vascular tumors in the maxillofacial region, rapid growth, leading to irreversible functional and aestheti c disorders - is a direct indication for active therapy. Treatment of facial hemangiomas in children with non-selective beta-blockers as an independent method refers to the method of choice, in case of impossibility or high risk of surgical treatment, or is part of the combined treatment.

Abdrashitova A.B., Saleev R.A.
Abstract
Introduction: cases of temporary disability in patients with loss of teeth, treated in dental health care organizations for 11 years. Objective: to study the group of diseases (tooth loss due to accident, removal or localized periodontitis (K08.1)) as a factor affecting the duration of temporary disability cases in the Republic of Tatarstan (RT) for 2007-2017. Material and methods: analysis of accounting and reporting forms 16-HV, 036/y, 035/y, 043/y in dental medical organizations fo r the period 2007-2017. Results: In the structure of the General dental morbidity with temporary disability, the group of diseases associated with tooth loss ranks third (7%) after odontogenic inflammatory diseases and injuries of the maxillofacial region. During the period of treatment and rehabilitation of working patients, there is a case of disability, the duration of which depends on the nosological form of the disease: the longest duration was established in the diagnosis of «peri-Implanitis» and « Loss of teeth in the lower jaw» (10.22±1.65 an d 10.98±0.69 days, respectively). Depending on the gender, cases of LN in the pathology studied are divided as follows: male patients - 37.5%, female - 62.5 %. The greatest number of cases of temporary disability associated with the group of the disease was revealed in 2011, the smallest - in 2008. We have established statistically significant differences in the frequency of hospitalization of patients depending on the nosological form groups of diseases of tooth loss (p<0.001).

Mishutina O.L., Volchenkova G.V., Shashmurina A.B.
Abstract
From 01.01.2018 year came into force the new order of Ministry of health of the Russian Federation «About carrying out of preventive medical examinations of minors» No. 514н, according to which the dentist is part of the medical Commission and examines children in the following life periods: 1 month, 2 years, 3 years, and then annually until the age of 17. The aim of our study was to compare the prevalence and intensity of dental caries in children, the prevalence of dental anomalies in children aged 2 years, 4 years, 6 years and 7 years, which were carried out preventive examinations in 2016 and 2017. In children aged two years, the prevalence of caries of temporary teeth increased from 14.3% in 2016 to 20.7% in 2017, the intensity of caries also increased by 2 times from 0.3 to 0.6 (p<0.05). In 2017, the prevalence of dental caries in children aged 4 years decreased by 7.4% compared to 2016 (p < 0.05). The prevalence of caries of permanent teeth at the age of 6 years in 2017 significantly decreased compared to 2016 data from 11.7% to 7.7% (p<0.05), in 7-year-olds, there was also a significant decrease in this indicator by 2 times from 5.3% in 2016 to 2.5% in 2017 (p<0.05), with the same value of the average CPI index in both groups. Preventive examinations of children allow timely detection of existing dental pathology and assess the effectiveness of dental care.

Klinovskaya A.S., Gurgenadze A.P., Zhuruli G.N., Bazikyan O.A., Abramyan S.A.
Abstract
Periodic disease - hereditary disease spreaded among the ancient peoples of the Mediterranean coast. The questionnaire and retrospective analysis of manifestations of periodic disease for patients living in the Russian Federation was composed in the child-maxillofacial department of the MSMSU named after A.I. Evdokimov. The research of medical histories of patients let us notice that every patient needs individual treatment and prophylaxis of frequent attacks. Nowadays Russian pediatricians are poorly informed about the periodic disease. As a consequence, we have detected a large number of mistakes in the diagnosis.

ROLE OF TOLL-LIKE RECEPTORS IN LICHEN PLANUS PATHOGENESIS
Mikhalev D.E., Stolyarova V.A., Cherevko N.A., Sysolyatin P.G., Baidik O.D.
Abstract
Among diseases of the oral mucosa, lichen planus (LP) is up to 13%. Over the past decade, the number of patients with this dermatosis has doubled. Currently, the etiopathogenetic factor of LP development remains unclear, but there are many theories of the development of this disease. However, in the literature there is no description of a common pathogenetic link. In connection with th e above, the authors believe that these theories can be combined with new scientific facts and ideas about the barrier role of innate, and in particular, mucosal immunity. The review article describes the role of mucosal immunity of mucous membranes - toll-like receptors (TLR), describes the mechanism of activation of the immune system through TLR2 and TLR4, shows the relationship of immune inflammation triggers - the reaction of food intolerance, factors that contribute to the development of hypersensitivity in the pathogenesis of LP. The mechanism is presented for the presentation of autoantigens to immunocompetent cells with the participation of heat shock proteins. The prospects for further study of TLR with the aim of increasing the effectiveness of the treatment of LP are presented.
