Aim. To evaluate the clinical efficacy of long-acting remineralizing medical means in the complex prevention of caries in pregnant women.

Materials and methods. The study was conducted on the basis of the Department of Therapeutic Dentistry of the Kuban State Medical University of the Ministry of Health of Russia. A total of 87 people were examined, aged 24 to 37 years, with different levels of oral hygiene 84 patients confirmed their consent to the treatment and prophylactic measures, after which three working groups were formed depending on the long-acting remineralizing agents used “Clinpro-XTVarnish” manufactured by 3MESPE, “Schmelz-versiegelungsliquid” manufactured by HUMANCHEME, “InnoDent Repair” manufactured by InnoDent LLP respectively) and 1 control group. The assessment of the dental status of pregnant women was carried out using indices: CFE, Fedorov-Volodkina oral hygiene index (HI), gingivitis index GI (Loe H., Silness J.).

Results. According to the data of a clinical study, it was determined that a high quality oral cavity sanitation with concomitant use of long-acting therapeutic and prophylactic agents increases the effectiveness of preventive measures in pregnant women.

Conclusions. The data obtained indicate the achievement of a long-term preventive result, which makes it possible to recommend the investigated fluorine-containing agents for remineralization of hard dental tissues in order to control the state of the oral cavity of women during pregnancy.

Aim. Substantiate the use of light exposure as physiotherapeutic methods of root canal treatment.

Materials and methods. For the study, 93 human teeth were taken, all teeth were divided into 3 groups of 31 samples. Optical microscopy was used as the main research method.

Results. The effect of laser radiation on biological structures depends on the wavelength of the energy emitted by the laser, the energy density of the beam, and the temporal characteristics of the beam energy. The processes that can occur in this case are reflection, absorption, scattering and transmission. The interaction of laser light and tissues occurs with optical proximity between them. This interaction is specific and selective, based on absorption and diffusion. The smaller the approach, the more light will be reflected or transmitted.

Conclusions. Currently, in endodontics, diode lasers are the best systems for disinfecting the root canal system due to their ability to penetrate the dentinal tubules. The optical proximity of their wavelengths to bacteria leads to the destruction of the latter due to the photo-thermal effect.

Aim. To assess the size of the alveolar ridge / part of the jaws in patients with gnathic mesial occlusion of the dentition.

Materials and methods. A study was carried out, during which we determined the structural features of the alveolar ridge of the upper and lower jaws of 50 adult patients (from 18 to 44 years old), and also studied the presence / absence of the relationship of this parameter with the inclination of the teeth.

Results. The smallest thickness of the alveolar bone in the upper jaw was observed in the area of the mesio-buccal root of the first molars and in the area of the first premolars and canines. The smallest thickness of the alveolar bone in the lower jaw was observed in the area of the vestibular surface of the first and second premolars, canines and incisors. The greatest thickness of the alveolar bone is observed in the distal-buccal region of the second molars.

Conclusions. A natural mechanism promotes dentoalveolar compensation, while maintaining the amount of bone in the region of the vestibular and lingual alveolar bones to maintain the integrity of the periodontium.

Aim. The study of the effectiveness of the use of the biologically active additive Reptin-plant in the complex treatment of patients with herpetic stomatitis.

Materials and methods. We examined 189 patients with a diagnosis of herpetic stomatitis, which were divided into 2 groups depending on the receipt of complex antiviral therapy with the inclusion of ERYX biomass lipid concentrate in the treatment regimen and without it. The following were assessed: clinical status, index assessment of the state of the oral cavity, state of local immunity, frequency of relapses and duration of the latency period.

Results. 57 (30.2%) patients were identified with a mild form of herpetic stomatitis (HS), the average severity of HS was determined in 93 (49.2%) and a severe course of the disease was diagnosed in 39 (20.6%) patients. Analysis of the index assessment of the state of the oral cavity (OHIS, PMA), molecular genetic parameters, immunological studies (lysozyme titer, phagocytosis, concentration of sIg A in saliva) showed a statistically significant difference when included in the complex treatment of Reptin-plant, demonstrating the benefits of using it.

Conclusions. The use of ERYX biomass lipid concentrate in the complex treatment of herpetic stomatitis effectively affects the dynamics of the course of the disease, improves the quality of life of patients.

Conclusions. The use of FibroMATRIX 3D collagen matrix for the regeneration of soft tissues of the oral cavity is an effective method for treating Miller Class I gingival recession.

The aim of this review article is to determine the positive and negative qualities and properties of restoration structures based on fiber posts. After endodontic treatment, it is necessary to strengthen the remaining tissues, since there is an irreversible decrease in the strength characteristics of the tooth.

Materials and methods.Produced a systematic review of the literature in the electronic databases Google Scholar and Pubmed. Articles based on the method of using fiberglass posts in clinical practice, analysis of methods for modifying the adhesive preparation of the dentin surface and the post itself, as well as publications related to the discussion of factors that led to the success/failure of the treatment are considered were included.

Results. 45 articles were reviewed in the course of information collection. As a result of the submitted articles analysis according to the exclusion criteria, the number of included studies has become 39.

Conclusions. Based on the literature studied, the use of structures based on fiber posts is an acceptable method ofpost-endodontic restoration of teeth. But, like any medical manipulation, it has its limitations and side effects.

Human nutrition has changed dramatically over the past few decades. The food industry now offers a huge variety of attractive foods that are high in sugars and acids, and the average human consumption of these soft drinks, snacks and convenience foods has skyrocketed. It has been established that nutrition significantly affects dental health. For example, excessive consumption of sugar and sugar-containing foods significantly increases the development of tooth decay. On the other hand, it has been proven that the mechanical properties of the hardness and elastic modulus of enamel and dentin are a predictor of tissue erosion and cariogenic changes in the structure of teeth and can be considered as diagnostic indicators. In this regard, it seems interesting and timely to review the literature data on the study of the effect of sugar and sweet foods on the hardness of tooth enamel.

Introduction. The malocclusion can be defined as developmental pathology of maxillofacial structures that affects function, esthetics, worsening life quality of a child.

The aim of this study was to review the literature and to investigate the reasons of the wide variation of malocclusion prevalence data in primary dentition.

Materials and metods. This study consisted of a systematic review and the search for the theoretical composition was performed in the Lilacs, PubMed and Scielo database using as descriptors the words Prevalence, Malocclusion, Primary Dentition, Teeth.

Results. This research afforded the authors to declare that the rates of malocclusion prevalence in primary dentition vary a lot so that it is inconclusive to rely on them.

Conclusions. According to the literature review, it is possible to emphasize that malocclusion prevalence rates depends on data collection geographic place, child’s dental and chronologic age, researcher’s professional skill on the issue of maloclussion diagnostic in primary dentition.

The aim of this review article is detailed analyzation of the effect of sodium hypochlorite on the structural components of dentin. This compound is one of the strongest antimicrobial medicines for root canal treatment. However, sodium hypochlorite in certain concentrations has a detrimental effect on dentin, which leads to the loss of its physicochemical properties.

Materials and methods. The study of publications was produced in the electronic databases such as Google Scholar, PubMed and ScienceDirect in the course of a systematic review of the literature. Included articles contain information about the on the effect of sodium hypochlorite on the structural components of dentin and the harmful effects of medicines for root canal treatment on organic elements.

Results. 67 articles were viewed during the rview. After analyzing the literature for inclusion criteria, the total number of publications has become 43.

Conclusions. According to the literature, it can be assumed that an increase in sodium hypochlorite concentration and its exposure time can lead to depletion of dentin organic matrix, which in turn, is responsible for the root fracture.

Orthodontic treatment may lead to the patients dissatisfaction with the anterior teeth microesthetics. This case report demonstrates the reasons of anterior direct restorations choice after digital mock-ups and patient compliance. The clinical procedures improved the patient's oral esthetics of teeth. At one week recall the general outlook of the maxillary anterior teeth was considered natural and esthetical. Clinically, restorations demonstrated no discolorations and dispolishing.

Aim of the study was, based on the analysis of dissertation research prepared in scientific laboratories and departments of the St. Petersburg Institute of Bioregulation and Gerontology, to present the contribution of the staff of this Institute to the development of modern gerontostomatology. Dissertation research carried out within the walls of the St. Petersburg Institute of Bioregulation and Gerontology in the field of gerontostomatology touched on the pathology of hard tissues and pulp of teeth, rehabilitation in case of tooth loss, periodontal diseases, oral mucosa, injuries and inflammatory diseases of the jaws and peri-maxillary soft tissues, as well as pathology temporomandibular joint and masticatory muscles in elderly and senile people.

Aim of the study was to evaluate the clinical efficacy of a nanomatrix with Miramistin based on M-Chip (Double White, Russia), which is used subgingivally as an addition to SRP (scaling and root planing) as a combination therapy in patients with chronic generalized periodontitis.

Materials and methods. T he s tudy i ncluded 4 5 p atients w ith c hronic g eneralized p eriodontitis (20 f emales a nd 25 males; age span is 35–60 years; mean age 57.87 ± 8.2 years). Patients with a probing depth ≥5 mm were included. Selected patients did not receive antibiotic therapy during the last 6 months of follow-up.

Results. The mean clinical parameter values between the M-Chip + SRP treatment group and the SRP control group showed a statistically significant improvement in clinical parameters at 6 months compared to baseline values for the following indicators: plaque index (API), gingival pocket depth at probing, Mühlemann Bleeding Index (BI), the level of clinical attachment.

Conclusions. SRP has been shown to be effective in reducing pocket depth, increasing periodontal attachment, and reducing inflammation. However, when SRP was used with the M-Chip, possible additional clinical benefits have been shown.

The recessions of the 3 Miller class are the most difficult in the prediction of the result during surgical treatment. Such recession in the anterior region of the mandible is often combined with a small vestibule of the oral cavity. The treatment of combined pathology in the standard protocol was provided in 2 stages: correction of small vestibule of the oral cavity and elimination of the recession by the method of the coronal advanced flap.

Aim. To develop the protocol of one-stage operation for patients with III miller class gum recession in combination with small vestibule.

Materials and metods. Surgical protocole. after conducting anesthesia at the region of the lower teeth held tunnel access to the region of teeth with gingival recession, formed split-thikness flap, discharge below the periodontal line connection 3 mm, mobilization of the flap.The flap is fixed with sutures Polyprophylene 6-0. Taken from the palatal free gingival graft. Placed in the region of holding vestibuloplasty fixed to the periosteum of the simple suture and suturing the donor area in the palate.

Results. The patients were found to have closing of the recession, the increase in the area keratinisation gums and keeping of the vestibule in the recovery area.

Conclusions. The development of a new one-stage treatment of recession 3 class at Miller in combination with vestibuloplasty allows you to more quickly treat patients with this pathology.

Resorption of the alveolar bone after tooth extraction is an irreversible process due to biological bone remodeling. It will greatly complicate the further treatment of patients for dental implantation, since for the latter a prerequisite is a sufficient volume of bone tissue. It leads to a protracted treatment process: the volume and timing of interventions increases. The literature review has shown possible methods of preservation of the alveolar ridge after tooth extraction and the results of their application.
