Since 2009, a group of enthusiastic doctors in Russia has initiated a professional movement for gratuitous implantation for people, mostly elderly, «Quality of life for our parents» for war veterans. Currently, charity events with a slightly modified slogan «Quality of life for our veterans» are held for participants in military operations and local conflicts, widows and mothers of soldiers. For more than 12 years, gratuitous implantation and dental prosthetics of socially dependent groups of the population has been practiced in several subjects of the Russian Federation. Many of the patients were medical indications implantation with immediate loading. The implantation protocol with intraoperative immediate prosthetics reduces the duration of treatment and is most in demand among patients. Patients start using prostheses immediately after implantation surgery. For some patients of the older age group, with facial injuries and cancer patients, this factor was the most decisive in improving their quality of life. Over the years of the campaign, methods and clinical protocols have been developed and optimized. As a result, a charitable program of dental rehabilitation of patients using dental implants «Quality of life for our veterans» was created.

Relevance. At the present stage, the choice of high-quality adhesive material is an important task of dentistry. The choice of the ideal adhesive material remains an urgent task to this day.

The aim of the study was to study in laboratory conditions the adhesive shear strength for fixing ceramic braces of a universal adhesive system containing 3D-SR monomer (Universal Bond II (Tokuyama Dental)) and adhesive cement ESTECEM II PLUS (Tokuyama Dental) before and after thermal cycling, with and without the use of varnish.

Materials and methods. For the preparation of samples, removed teeth without carious lesions and large fillings were used. Samples of 60 teeth were divided into 2 groups (n=30) with and without varnish. In each group, the adhesive shear strength was studied before and after thermal cycling (n=15). The following materials were used: two-component self-curing dental adhesive system Universal Bond II (Tokuyama Dental), varnish SHIELD FORCE PLUS (Tokuyama Dental), adhesive fixing cement double curing ESTECEM II PLUS (Tokuyama Dental). Tests of the adhesive shear strength of the prepared samples were carried out on a universal testing machine «SYNTHEZ 5» at a traverse speed of 5 mm/min according to the methodology of GOST R 56924-2016 (р. 7.15).

Results. The adhesive strength index of the control group (before thermal cycling) was 4.33±1.28 MPa, in the main subgroup (after thermal cycling) 3.48±0.81 MPa. The presence of varnish on the enamel surface did not affect the adhesive strength of the bonding of the bracket system and tooth tissue and amounted to 4.50±0.25 MPa and 3.14±0.82 MPa, respectively (p= 0.0005).

Conclusions. The presence of varnish on the enamel surface did not affect the adhesive strength of the connection of the bracket systems with tooth tissues in the control (before thermal cycling) and the main (after thermal cycling) subgroups (p≤ 0.05). The adhesive strength index in the control subgroups (before thermal cycling) and the main ones (after thermal cycling) of both groups differed slightly. Thermal cycling reduces the adhesive strength of braces with tooth tissues when using universal adhesive Universal Bond II (Tokuyama Dental) (p≤ 0.05).

This article discusses current research methods of periodontitis and periimplantitis with the use of immunological diagnostic methods in relation to the hormonal balance of the body, the level of defensins and metalloproteinases. The main conclusions of studies of the composition of saliva in inflammatory periodontal diseases are presented. Salivadiagnostics is used not only as definitions of pathology of the oral cavity, but also of the whole organism as a whole.

Lack of response to the treatment of periodontal disease depends on systemic disturbances, one of which is vitamin D deficiency. Vitamin D deficiency is an absolute risk factor for osteopenia and osteoporosis for adult and aged patients. The analysis of clinical and laboratory studies results revealed a positive dynamic of the treatment given. The obtained data prove the necessity of vitamin D status correction in the combined treatment of the periodontal profile patients.

Relevance. Denture stomatitis, including fungal infection, which affects many wearers of removable dental prostheses, has a multifactorial etiology with poor oral hygiene as the main predisposing factor. Therefore, the search for means that contribute to the prevention of occurrence and elimination of denture stomatitis in persons using removable dental prostheses remains relevant.

Objective. The effect of the adhesive cream for fixation of dentures Asepta Рarodontal with plantain extract on the mucosal microbiome and secretory immunity of the mouth of patients using removable dentures was evaluated.

Materials and Methods. The content of secretory immunoglobulin A (sIgA) in saliva was studied by enzyme-linked immunosorbent assay and microbiological examination for periodontopathogens (Prevotella intermedia, Bacteroides forsythus, Treponema denticola, Actinobacillus actinomycetemcomitans, Porhyromonas gingivalis), as well as Streptococccus spp, Staphylococcus spp and Candida spp in 3 groups of patients who did not use any dental prostheses (1 control group, 30 people). ), as well as those who were made partial removable acrylic dentures from the first day of application were offered to use domestic adhesive cream for fixation of dentures Asepta Рarodonta (2 main group, 30 people) and who were made partial removable acrylic dentures, but their adaptation period and subsequent use of dentures passed without the use of any adhesive means for fixation of dentures (3 comparison group, 30 people).

Results. It was found that after 6 months of application of adhesive cream for fixation of dentures with plantain extract there was a significant decrease in detection of Bacteroides forsythus and Porphyromonas gingivalis in comparison with the control group, as well as a significant increase in the level of sIgA, which was noted 1 month after the beginning of application of Asepta Carodontal denture fixation agent and continued after 6 months. This indicates the strengthening of secretory immunity, which leads to increased binding of microbes in saliva with their further excretion, inhibition of adhesion of C. albicans to the walls of the denture and epithelial cells of the oral mucosa, which ultimately contributes to a decrease in colonization of the oral mucosa epithelium by fungi and a decrease in the incidence of stomatitis.

Conclusion. Prevention of denture stomatitis by optimizing the microbiome of the oral mucosa and mucosal immunity is possible due to the use of adhesive cream for fixation of dentures Asepta Carodontal, as it creates the possibility of preserving and optimizing the microbiocenosis and immune balance in the oral cavity after dental prosthetics, which allow us to recommend the use of adhesive agents for fixation of removable dental prostheses, including cream Asepta Carodontal.

The aim of this research was to identify the factors that can further the development of infectious and inflammatory complications of a fractured mandible and search for ways to eliminate them. 643 medical histories of patients with mandibular fractures that received inpatient treatment in the maxillofacial surgery department in the State Budgetary Healthcare Institution of the Volgograd region «The Regional Clinical Hospital №1» between January 2019 and December 2021 were studied. The results of retrospective analysis of the frequency rate and nature of inflammatory complications from 2019 to 2021 were presented. The relation was revealed between the frequency rate of inflammatory complications, the quality of medical services, the time people wait until seeking medical help, and also whether patients have chronic diseases, which could lead to metabolism disruptions, that can cause chronic endogenous intoxication, secondary immune deficiency and reparative regenerations disruptions. Recommendations were proposed about a more reasonable treatment plan and elimination of common mistakes during the stages of medical care, which could reduce the risk of inflammatory complications.

The article is devoted to the method of improving bone tissue regeneration after tooth extraction and filling the hole with tissue of an engineering design – scaffold. Biomimetic SFERO (R) in the form of a gel was used as a scaffold. SFERO (R) was used to improve bone regeneration and subsequent implantation and prosthetics. The preparation of Russian production, developed and introduced into practical health care and allowed for transplantation to humans in the Russian Federation (date of state registration June 5, 2004, IN 269774, valid until March 24, 2033). The paper presents clinical examples of application of SFERO(R)gel in patients after extraction of one or more teeth of the chewing group of teeth.

After injury or removal of neoplasms, bone, soft tissue scar defects and deformities are formed. Methods of reconstructive bone surgery do not reliably allow to restore defects in full. The main problem is constriction, subsequent atrophy and deformation of soft tissues in the defect area. Dental implant-prosthetic rehabilitation in the area of significant bone defects requires the use of design and prototyping of the final result using computer programs and diagnostic models. The clinical experience of using an individual temporary endoprosthesis, a «tissue expander» made by layer-by-layer synthesis (3D printing) of biologically inert plastic according to CT data of the patient is presented. The expander is made in the form of a 3D element for the formation of the necessary volume of soft tissues in the patient for a period of 2–4 months, fixed under the periosteum, in the area of the lateral defect of the lower jaw with intraosseous screws. Dental implants are installed in front. Intraoperative direct prosthetics was performed. A temporary screw prosthesis is installed in the mouth. After 3 months, 3 implants were installed and bone grafting was performed. Final prosthetics 7 months after the start of treatment.

The aim of the work was to study the antibacterial effectiveness of anodic dissolution of copper electrodes in endodontic treatment of teeth with root canals obliterated by more than half the length of the root.

The study included two stages: experimental and clinical. In an experimental study using automatic cultivation of microorganisms in liquid nutrient media, it was found that anodic dissolution of a silver-copper electrode was more effective with respect to the clinical isolate of P. Intermedi and of C. Albicans, as well as a mixed culture of pathogenic microorganisms Streptococcus sanguis + Enterococcus faecium – a copper electrode. In the clinical part of the study, 30 patients with chronic forms of pulpitis were treated using intra-channel anodic dissolution of a copper electrode in the teeth, where the root canals were obliterated by more than half the length of the tooth root.

After the procedure, not a single type of pathogenic microorganisms found in the root canals before treatment was detected. All patients had no complaints, and a control X-ray examination showed no pathological changes after year treatment.

Purpose: to determine the frequency of occurrence of gnathological complications during therapeutic treatment in the opinion of dentists-internists, dentists-general practitioners and to identify their approaches to the treatment of this group of patients.

Materials and methods: a survey of dentists-internists, dentists-general practitioners was conducted (82 respondents). The questionnaire was provided for filling out in paper form, as well as in electronic form by Google Forms, depending on the preferences and location of the respondent.

Results: this survey showed a high incidence of gnathological complications during therapeutic treatment, 92.68% of respondents encountered complications from the TMJ after treatment in patients. Most often, complications occurred during root canal treatment (34.2%) and work lasting more than 60 minutes (61.5%). Both similar and different features were identified in the treatment of this group of patients.

Conclusions: despite the high incidence of gnathological complications in the therapeutic rehabilitation of patients, according to dentists, there is currently no unified approach to the treatment of patients in this group and requires further development.

Relevance. Correcting periodontal and aesthetic problems associated with irrational previous fixed prosthetics is a difficulty faced by orthopedic dentists all over the world. One of the solutions at the moment is to use the idea of vertical preparation with further rational temporary and permanent prosthetics

Objective. Assessment of symptoms in patients with vertical preparation, with mandatory curettage of the gums with a flame-shaped bur, receiving local therapy, including the use of the domestic drug Superlimf adhesive plates.

Materials and methods. During the clinical study, a comparative analysis of the symptoms of gums traumatized during preparation was carried out in groups of patients with different treatment options. A total of 36 people took part in the study. The observation was carried out for 28 days.

Results. It was found that groups of patients treated with Superlimf or Solcoseryl showed the best results in terms of increasing gum volume.

Conclusion. Our data allows us to conclude that the use of additional medications such as Superlimf or Solcoseryl Dental can speed up the gum healing process in some patients, which is why it is possible to move to the stage of permanent prosthetics earlier.

Currently, patients are increasingly turning to dentists with complaints about unsatisfactory dental aesthetics. All this is associated with both carious and non-carious lesions of the teeth. Methods of dental treatment today are diverse and satisfy the desires of even the most fastidious patient. So, in the treatment of dental caries, dentists prefer filling. All kinds of composite materials, mainly of foreign production, are used for sealing. Due to the changed global trends, we are faced with the task of finding and developing a new domestic nanofilled light-curing composite that will not be inferior in its properties and composition to leading foreign analogues.

The materials used to restore the crown part of teeth after endodontic treatment in modern conditions are presented. The advantages of post-endodontic dental treatment using a variety of pin structures in the system of providing dental care to the population are shown. The relevance of the search and development of new domestic materials for intra-channel pins with improved properties is shown in the program that promotes import substitution in dentistry, thereby solving one of the main strategic components in improving the quality of life of the patient.

The majority of periodontal visits in dental care to the population are made up of patients in the elderly age group (according to the WHO classification, these include persons 60–74 years old). Features of periodontal treatment of elderly people require a new approach to standard treatment regimens. In recent years, treatment with the «Vector» device (Dürr Dental, Germany) has found widespread use in periodontal consultations. The purpose of the study is to determine the volume of periodontal care for the elderly population in the State Medical Institution of the RO «SP» in Rostov-on-Don in dynamics from 2020 to 2022 using the «Vector» device. Results of the study: periodontal doctors performed ultrasonic removal of supragingival and subgingival dental plaque in the area of one tooth (using the Vector apparatus) in 2020, 1825 services, and in 2022 2562, which is 737 services more than in 2020, At the same time, 1241 services were performed for elderly people in 2020, and in 2022 there were 552 more services.

Conclusion: the use of the «Vector» device in addition to traditional treatment regimens for chronic generalized periodontitis in elderly patients accelerates periodontal recovery time.

The article presents clinical and diagnostic aspects of leukoplakia of the oral mucosa and red border of the lips and approaches to the treatment of the verrucous form of leukoplakia. The effectiveness of laser thermal ablation and adhesive balm with magnetic polymers, hexethidine, cytylpyridinium chloride and hyaluronic acid has been shown, which opens up new possibilities in the treatment of this pathology with minimal risk of complications.

Introduction. Currently, the direction of minimally invasive surgical interventions in surgical dentistry is relevant to reduce the time of postoperative rehabilitation. Detachment of the mucoperiosteal flap during dental implantation leads, depending on the extent of the defect, to a hematoma, which increases the risk of complications (suture dehiscence, wound infection). Because of this, treatment tactics have been developed that allow dental implantation to be performed using surgical navigation templates using a flapless technique. However, despite the obvious effectiveness and efficiency of the method, there are few experimental studies to substantiate the flapless technique of dental implantation.

Purpose: clinical substantiation of the effectiveness of the use of flapless navigation techniques for dental implantation Materials and methods: the clinical study included 40 patients with secondary partial edentia. The patients were divided into two groups: the main and control groups. A life history was collected, as well as a history of the development of the present disease. The patients underwent dental implantation surgery in the area of the lateral groups of teeth. In the main group, dental implantation was carried out using a navigation template with a complete protocol and the use of a “flapless” technique; in the control group, dental implantation was carried out with a full-thickness incision and detachment of the mucoperiosteal flap. The evaluation criteria were clinical parameters of healing in the early postoperative period, the height of the soft tissues around the dental implant in the late postoperative period (CBCT, probing), as well as the presence of complications (mucositis, peri-implantitis). The data was entered into a table for further statistical analysis.

Results. In the control group, the average height of the formed gingival cuff was 1,55±0,43 mm, 95% CI (1,34–1,75), with primary healing the average height was 1,64±0,44 mm, 95% CI (1,31–1,98), with secondary healing the average height is 1,46±0,43 mm, 95% CI (1,17–1,75). In the main group, the average height of the formed gingival cuff was 2,42±0,45 mm, 95% CI (2,21–2,62), with primary healing the average height was 2,40±0,45 mm, 95% CI (2,17–2,63), with secondary healing mean height 2,50±0,53 mm, 95% CI (1,19–3,81). In the control group, the average loss of marginal bone tissue was 1,27±0,47 mm, 95% CI (1,05–1,49), with primary healing the average loss was 0,96±0,29 mm, 95% CI (0,73–1,18), with secondary healing the average loss is 1,53±0,44 mm, 95% CI (1,23–1,82). In the main group, the average loss of marginal bone tissue was 0,50±0,31 mm, 95% CI (0,35–0,65), with primary healing the average loss was 0,48±0,33 mm, 95% CI (0,31–0,65), with secondary healing the average loss is 0,63±0,12 mm, 95% CI (0,35–0,92). Comparison of the main and control groups in terms of the height of the formed gingival cuff showed a statistically significant difference (p<0,001). This indicator differs significantly between groups with primary (p=0,0004) and secondary wound tension (p=0,004). In the early period, in the control group of 20 patients, 8 (40%) had mucositis, 2 (10%) had peri-implantitis, in the main group 3 (15%) had mucositis. In the late period, in the control group, 7 (35%) had mucositis, 1 (5%) had peri-implantitis, in the main group, 2 (10%) had mucositis. A comparison of the main and control groups in terms of the presence of pain, as well as the presence of complications in the early and late periods, showed a significant difference. In the control group, 60% of patients felt pain, and in the main group, 15% (p=0,009). The presence of complications in the early period was observed in 50% in the control group and in 15% in the main group (p=0,042). In the late period, the proportion of complications decreased and amounted to 40% in the control group and 10% in the main group (p = 0,03). The groups differ in the proportion of primary and secondary healing, so in the main group 85% of patients had primary healing, and in the control group patients with secondary healing of 55% predominated (p = 0.02). Comparison of the study and control groups in terms of loss of marginal bone tissue showed a statistically significant difference (p<0,001).

Conclusion. The use of a flapless navigation technique can reduce the likelihood of complications in the early and late postoperative periods, while predictably controlling the height of the gingival cuff.
