The prevalence of periodontal disease constitutes a very high percentage of all stomatological diseases and falls on the age group of 15-19 years (55-89 %) and 35-44 years (65-98 %). In the adult population, by the age of 35-44, a sufficient number of chronic background diseases accumulate, violations of carbohydrate and mineral metabolism, and foci of chronic infection appear. Locally in the oral cavity inadequate treatment or complete absence of gingivitis treatment in adolescence leads to the spread of inflammation to underlying periodontal tissues. Current non-surgical methods of periodontitis treatment include various pharmacological groups of drugs, including collagen and digestase.

The study included patients with a form of verrucous leukoplakia of the oral mucosa, the treatment of which was carried out by traditional scheme (cryosurgery and topical anti-inflammatory treatment - 1st group) and with postoperative ozonated olive oil solution with a known peroxide value (second group). To assess the effectiveness of the chosen postoperative wound method using a comparative analysis of the results of the patients oral fluid with the 1st and 2nd groups. As a criterion used indicator of the activity of superoxide dismutase (SOD) oral fluid. We get more significant increase in the activity of SOD oral liquid in the postoperative period using ozonated oil than adaptive zoom cryoablation. Use during the postoperative period in the complex treatment of the ozonized solution of olive oil resulted in lower levels of oxidative stress in the saliva due to the persistent and long-term increase of activity of salivary SOD that accelerated repair processes, improved during the wound healing process, reduce the life of the oral mucosa healing (confirmed by morphological studies) compared to conventional treatments.

The actual problem of aesthetic medicine is the delimitation of professional responsibility zones in the face area between dentists and cosmetologists, since aesthetic services are one of the most vague issues in the field of legal regulation. The interdisciplinary approach is an innovative solution for a team of physicians of various specializations who form and implement a comprehensive treatment plan for patients. In this paper, we reflected the intersection of professional occupational responsibility areas at the junction between dentistry and aesthetic medicine. The purpose of this study is to analyze the clinical and legal aspects of the use of botulinum toxin type A and hyaluronic acid in dental practice.

The article presents information on the anatomy of the first upper molars the residents of the Moscow region obtained by cone-beam computed tomography. To date, the dentists of the Russian Federation use the data on anatomy of root canals obtained by foreign authors. The achievements of science and technology in recent years allow a wide use of cone-beam computed tomography to study the anatomy of the root canal system, which is extremely important for dentists working in endodontic practice.

Aim. Conducting a comparative analysis of the Pont and Linder-Harth methods in measuring the width of the dental arches in the region of premolars and molars in people with different gnathic, dental facial types and dental arches taking into account the dimensions of permanent teeth. Materials and methods. The materials of the research were the results of measurements of the cephalometric parameters and diagnostic gypsum models of the dentition senes of 227 people of the first period of adulthood with a complete set of permanent teeth, physiological occlusion and various gnathic and dental types of the face and dental arches. Measurement and calculation of the parameters of the dental arches in the transversal direction was carried out using the methods of Pont and Linder-Harth. To determine the dental type of face, estimation was made of the diagonal sizes of the facial part of the head between the cephalometric points t and sn.When establishing the gnathic type of face, a gnathic index was used, calculated as the percentage of diagonal and transversal dimensions of the facial part of the head. Transversal dimensions represented the width of the face between the goat-bearing landmarks t-t. Gnathic variants of dental arches were determined taking into account the dental index calculated as the ratio of the half sum of the width of the crowns of 14 teeth to the width of the dental arch between the second molars. The types of the dental system were determined from the summation of the width of the crowns of the upper teeth. Results. In humans with different gnathic, dental types of face, the Pont and Under-Harth methods are acceptable when examining mesognathic dental arcs as an estimate of transverse dimensions. There was no significant difference between the calculated values and actual sizes in patients with different types of dental system, both in the premolar and molar regions. When studying brachygnathic dental arches in people with different gnathic, density facial types, the indices obtained by the Under-Harth method are reliably smaller than the actual values. Thus, the use of the Linder-Harth method in the analysis of brachygnathic dental arches has significant errors. Analysis of dolichognathic dental arches in people with different gnathic, dental types of face shows that the calculated indices using Pont indexes are significantly more than actual values. This indicates that the use of the Pont method in the analysis of dolichognathic dental arches has significant errors and cannot be used to assess latitudinal parameters. Conclusion. Optimization of diagnostic and treatment methods for adult patients with anomalies of the dentoalveolar system not only makes it advisable to revise the conventional traditional diagnostic regimens for determining the shape and size of dental arches in order to increase the effectiveness of orthodontic treatment, but also implies the expansion of existing modern ideas about the morphology of the craniophatic complex and its relationship to the shape, the size of the dental arches. Mathematically derived dependences of dental types of dental arches on their transversal parameters are informative, diagnostic significant values that can be used to predict the shape and size of dental arches in the treatment of patients with dentoalveolar anomalies in order to achieve the optimal functional and aesthetic result.

Earlier the lower human jaw was used to study prostheses in a toothless lower jaw, which is not always available. To conduct experiments it is nessesary to create a conditions approximating to real situations, which was not used for researchesof the edentulous mandibl prostheses.

A comparative analysis of the application of the method treatment of commissural cracks with the use of collagen-containing injections and the traditional method of treatment is carried out. The attention is focused, on the method of treatment the oral mucosa with the use of collagen-containing injections. It has been established that with this method of treatment, it is noted to remove pain syndrome and the phenomenon of inflammation, to shorten the periods treatment of chronic injury and to achieve remission and complete restoration of the anatomical shape of the lips.

Providing optimal root canal irrigation and subsequent sealing of the size and shape is a necessary component at the stage of endodontic treatment of teeth. The creation of these optimal conditions is often complicated anatomical features of the structure of root canals, obliteration of, prior poor treatment. Application of modern Nickel-titanium endodontic instruments together with a new improved entomotherapy allows root canal treatment better, faster, without a big risk of complications, while maintaining the anatomical form of the channel.

Dental membrane has a certain set of parameters and characteristics including thickness, surface density, elastic modulus, surface tension, and stress or elongation. According to these characteristics the behavior of the membrane can be predicted after implantation to calculate the resorption time, strength, and other properties. The physico-mechanical properties of some commercially available dental membranes were investigated in these studies.

The addition of chlorhexidine acetate compounds to composite material can increase its antimicrobial properties and reduce the risk of secondary caries. In order to evaluate the antimicrobial activity, samples of composite material containing an antimicrobial additive were prepared by adding various amounts of chlorhexidine acetate to the composite paste. The study showed that the addition of chlorhexidine acetate to the composite material Restavrin increased its antimicrobial properties.

The result of implant treatment must be a complete rehabilitation of the patient with some form of tooth loss. Modern standards of treatment have an implant survival rate of 99 % in the first year of treatment and a 90-92 % survival rate after 10 years of implant installation. To achieve these results, you need to carefully perform all stages of dental implantation. The main stages in this method of treatment are: patient examination, diagnosis and treatment planning; the surgical stage; the prosthodontic stage; the rehabilitation stage. Examination of the patient prior to treatment should be considered an important stage in the planning of all possible medical actions in dental implant treatment.
