Relevance. The new Rules for the provision of paid medical services by medical organizations, approved by Decree of the Government of the Russian Federation of March 11, 2023 No. 736, are aimed at developing and improving the legal framework for the provision of medical services. In this regard, it seems relevant to draw the attention of doctors dentists on the legal aspects of contractual relations. The main goal of the work. The purpose of the study is to draw the attention of dentists to certain legal aspects of contracts for the provision of paid medical services, which are essential for the effective protection of their interests in the event of disputes regarding the proper performance of contractual obligations. Approaches used. The provisions of legislative and by-laws related to paid medical services have been studied. A survey of 125 respondents (72 dentists, 53 consumers of medical services) was conducted on some legal aspects of the provision of paid medical (dental) services. Results. Using the survey method, the attitude of dentists and consumers to pre-contractual relations, to information about medical workers involved in the provision of paid medical services, as well as to the provision in written form of rules for using the results of the service or their storage is shown. Main conclusions. When providing paid medical (dental) services, it is necessary to pay special attention to: 1) pre-contractual notification to consumers in writing about the consequences of failure to comply with the instructions (recommendations) of the performer (medical worker providing a paid medical service; 2) notification to the consumer ( to the customer) information about medical workers involved in the provision of paid medical services, about the level of their professional education and qualifications; 3) providing the consumer with written rules for using the results of the service or storing them.

Background. One of the autoimmune diseases is pemphigus, a chronic malignantly occurring autoimmune dermatosis accompanied by the development of blisters on the skin and mucous membranes. Isolated lesions of the SOPR occur in 10–20% of cases, complicating differential diagnosis. Numerous studies have proven the role of herpes virus infection as an aggravating factor in the course of true acantholytic pemphigus. The aim of the study was to determine the features of the clinical course of vulgar pemphigus against the background of reactivation of chronic EBV infection (glossitis caused by EBV). The clinical case of a patient with a diagnosis of “Vulgar pemphigus. Glossitis caused by the Epstein-Barr virus”. The anamnesis of the disease was carefully collected, a clinical and laboratory examination was performed with a cytological examination of a smear taken from a LITTER, a general blood test with an expanded leukocyte formula, C-reactive protein. In order to diagnose the viral load, PCR diagnostics was performed on the DNA of the herpes virus 1, 2, 4, 5 types in saliva, on the DNA of EBV in the blood, quantitatively. Specific antibodies of Ig classes M and G to EBV were determined by the ELISA method. Results. Due to the lifelong persistence of EBV in the structures of the oral cavity, its reactivation leads not only to chronic pastoral infection and the local development of the corresponding glossitis, but also, first of all, to a decrease in the level of local immunity. This fact aggravates the course of pemphigus, shortens the period of absence of relapse. The appointment of antiviral therapy at the first visit allowed to stabilize the symptoms caused by EBV, which led to positive dynamics in the course of pemphigus against the background of average dosages of prednisone in a shorter time. Conclusions. With clinical and laboratory confirmation of chronic EBV infection (glossitis caused by EBV), it is recommended to include antiviral and immunocorrective drugs, systemically and topically, in the complex treatment of pemphigus erythematosus.
背景。丘疹性荨麻疹是自身免疫性疾病之一，是一种慢性恶性自身免疫性皮肤病，伴有皮肤和粘膜水疱。在 10-20% 的病例中，SOPR 会出现孤立的病变，从而使鉴别诊断变得复杂。大量研究证明，疱疹病毒感染是真性溶血性丘疹性荨麻疹病程中的加重因素。本研究旨在确定在慢性 EBV 感染再激活（EBV 引起的舌炎）的背景下，寻常型丘疹性荨麻疹临床病程的特征。该临床病例被诊断为 "庸俗性丘疹性荨麻疹"。由 Epstein-Barr 病毒引起的舌炎"。仔细收集了该病的病史，进行了临床和实验室检查，包括从 LITTER 采集的涂片的细胞学检查、用扩大的白细胞公式进行的一般血液检查、C 反应蛋白。为了诊断病毒载量，对唾液中的 1、2、4、5 型疱疹病毒 DNA 和血液中的 EBV DNA 进行了定量 PCR 诊断。用 ELISA 方法测定了 EBV 的 M 和 G 类 Ig 特异性抗体。检测结果由于 EBV 终生存在于口腔结构中，它的再次激活不仅会导致慢性口腔感染和相应的舌炎，而且首先会导致局部免疫水平下降。这一事实加剧了丘疹性咽峡炎的病程，缩短了不再复发的时间。首次就诊时进行抗病毒治疗，可以稳定 EBV 引起的症状，从而在较短时间内，在泼尼松平均剂量的背景下，使丘疹性荨麻疹的病程呈现积极的动态变化。结论在临床和实验室证实慢性 EBV 感染（EBV 引起的舌炎）的情况下，建议将全身和局部抗病毒和免疫纠正药物纳入丘疹性红斑狼疮的综合治疗中。

Relevance. Improving the diagnosis and provision of periodontal care to patients with chronic periodontitis in combination with herpetic and candidal lesions is an urgent goal of many modern studies. The COVID-19 pandemic, and the post-COVID syndrome, have sufficiently changed the view of dentists on the diagnosis and treatment of these comorbid and associative diseases. Purpose: comparison of the Shannon biodiversity index of the studied groups. Materials and methods. We conducted a single-center, randomized, prospective, clinical-microbiological, controlled, open study to determine the comorbidity of herpes and candida infections with chronic generalized periodontitis; 61 patients (aged 18 to 19 years) were examined. Results: In general, I would like to emphasize that the less we record the Shannon biodiversity index, the healthier the space under study, in our case the periodontal area, is. Since less biodiversity is a formed stable microbial community, contributing to the preservation of constancy and protection from opportunistic and pathogenic forms. In conclusion, I would like to note that the pathogenesis of COVID-19 is truly interesting and unique, and there is practically no data on changes in the spectrum of periodontopathogenic and normal microbiota in the pathology under consideration, therefore the use of metagenomic analysis of the oral microbiome against the background of a coronavirus infection will expand the understanding of the course of these comorbid diseases. Therapeutic measures aimed at reducing the viral load in periodontal tissues can help not only reduce the number of possible niches for the life of the virus, but also strengthen periodontal tissues, preventing the development of comorbid and associative forms of diseases.

Background. As a result of teeth loss, a complex of factors arises that leads to changes in the dental system and impaired speech of the patient. Speech is an important communicative function, and assessing its intelligibility allows us to evaluate the result of prosthetic treatment. It is necessary to ensure unimpeded movement of the tongue, lips, cheeks and to fill in the missing components of the sound-producing system to restore phonetics. The optimal method of restoring complete absence of teeth is treatment with complete removable plate dentures made of acrylic plastics. Adaptation to this design over time restores the functions of sound pronunciation and the digestive system. The adaptation process depends not only on the patient’s abilities, but also on the quality of the manufactured structure. The discrepancy between the prosthetic bed and the base of the orthopedic structure is manifested by a violation of fixation and stabilization, which leads to pain. Aim. To evaluate the dynamics of the phonetic adaptation process of patients after the application of a complete removable prosthesis. Materials and methods. Application of phonetic control according to W. Wright and logopedic exercise “Drawing”. Results. During the study, the results were obtained that patients of groups II, III and IV improved their initial indicators, while group III increased their indicators by 25%. On average, the groups that followed the recommendations improved their results by 19.4%. Conclusions. According to the results obtained, the exercises used help patients with removable plate prostheses to adapt to them faster and accelerate the restoration of sound reproduction.
背景。由于牙齿缺失，一系列复杂的因素导致牙科系统发生变化，患者的言语能力受损。言语是一项重要的交流功能，评估言语的清晰度可以帮助我们评估修复治疗的效果。有必要确保舌、唇、颊的活动畅通无阻，并填补发音系统缺失的部分，以恢复语音功能。修复全口缺失牙的最佳方法是使用丙烯酸塑料制成的全口活动板式假牙。随着时间的推移，适应这种设计可以恢复发音和消化系统的功能。适应过程不仅取决于患者的能力，还取决于制造结构的质量。假体床与矫形结构基座之间的差异表现为固定性和稳定性受到破坏，从而导致疼痛。目的评估使用全可摘义齿后患者语音适应过程的动态变化。材料和方法。根据 W. Wright 和逻各斯练习 "画图 "进行语音控制。结果。研究结果显示，II、III 和 IV 组患者的初始指标有所改善，而 III 组患者的指标提高了 25%。平均而言，遵循建议的各组患者的治疗效果提高了 19.4%。结论。根据所获得的结果，所使用的练习有助于活动板式义齿患者更快地适应活动板式义齿，并加快声音再现的恢复。

Relevance. To maintain dental health and maintain the normal structure of the dental system, a deep understanding of methods for restoring lost dental tissue is necessary. When restoring class II carious lesions, open and closed sandwich techniques were used, as well as various methods of manipulating composite materials. Systematization of existing research will allow the dentist to better navigate the available techniques and provide better treatment to his patients. Aim: To conduct a systematic review of the effectiveness of the method for restoring proximal contacts of posterior teeth. Materials and methods. As part of the study, a systematic analysis of the technique for restoring contact points of teeth was carried out, in compliance with established criteria. Initial data were obtained by searching the Google Scholar, ScienceDirect, PubMed, ResearchGate, CyberLeninka and eLIBRARY.RU databases using the following key terms: «recovery methods», «contact point», «open sandwich», «closed sandwich», «filling technique», «point of contact», «closed centripetal», «open centripetal». Results. To conduct a systematic review, 7 articles were reviewed on the seal quality of restorations made using the open sandwich, closed sandwich, and total bonding methods. In 85% of cases, the open sandwich method was indicated by the authors as the most appropriate for creating sealed class 2 restorations. Conclusions. The best tightness of restorations in in vitro studies in 85% of cases was achieved using the technique of filling an open sandwich. The tightness of the restoration not only affects the choice of material, but also prevents its application. Further comparative in vivo studies on the survival of class 2 restorations made using the open sandwich or total bonding method are needed.

Item. A review of the literature is presented on the current problem of maxillofacial surgery – methods of fixation of bone fragments in fractures of the lower jaw. The purpose of the study is to study publications on methods of fixation of fragments in fractures of the lower jaw in the comparative aspect of their influence on the clinical course. Methodology. The publications of domestic and foreign authors on modern methods of fixation of bone fragments in fractures of the lower jaw were studied, and a comparative analysis of their effectiveness was carried out. Results. Currently, orthopedic and surgical methods of immobilization of bone fragments are used, which are used both in isolation and in various combinations. During surgical treatment with the help of mini-plates, it is possible to perform optimal reposition and stable fixation of fragments, however, the traumatic nature of the operation, leading to bone hypoxia, slows down the processes of reparative osteogenesis and leads to the development of postoperative complications. The use of bone glue-cement makes it possible to achieve reliable fixation of bone fragments, accelerate the formation of a callus. At the same time, there is no need to remove the glue, since it is a biodegradable material. Conclusions 1. None of the currently used methods of fixation of bone fragments in clinical practice for fractures of the mandible, both orthopedic and surgical, as well as in their combination, can fully meet the optimal conditions of reparative osteogenesis. 2. A promising alternative method is the use of bone adhesives that fill the bone voids between fragments, which contributes to their stable fixation and reparative osteogenesis, biodegrading simultaneously with the formation of a callus.

The use of interim (provisional) prostheses is an obligate stage of modern dental practice. The problem of provisional bridges recognized by most experts is their use under heavy occlusal stress due to the possibility of their fracture. The development of a simple method of reinforcing provisional of prostheses during a clinical appointment that does not require special equipment is an urgent scientific and practical task. Objectives. The goal of this study was to evaluate the stress distribution in fiberglass reinforced and non-reinforced short-span and long-span provisional bridges according to different acrylic and bis-acrylic resin. Methodology. For this purpose, four finite element models were developed to reproduce the properties of prosthetic materials and hard dental tissues (Young’s modulus, Poisson’s ratio, hardness). Each model was subjected to a vertical load of 100 N applied to the middle of the bridge. Calculations were carried out in APM 3D Studio, and the results obtained were monitored in Ansys 12.2. The results obtained were displayed on the monitor screen, printed and analyzed. Results. Stress distribution pattern for an acrylic non-reinforced short-span bridge (model 1) showed the highest stress (4.2–5.2 n/mm2) in the area of the occlusal surface. Stress distribution pattern for an acrylic non-reinforced long-span bridge (model 2) showed the highest stress (11.4–12.3 n/mm2) both in the load zone and in the cervical zones of the connector facing the defect. Stress distribution pattern for acrylic reinforced long-span bridge (model 3) showed the highest stress (10.5–12.0 n/mm2) in the area where the fiber reinforcing tape is located deep in the bridge. Stress distribution pattern for bis-acrylic reinforced long-span bridge (model 4) showed the highest stress (9.8–10.5 n/mm2) observed both in the area where the glass fiber reinforcing tape is located and on the occlusal surface. Conclusion. Finite element analysis confirmed the feasibility of fiberglass reinforcement of long-span provisional bridges made of acrylic or bis-acrylic resin.
使用临时修复体是现代牙科实践的必经阶段。大多数专家都认识到临时牙桥的问题在于，在咬合压力较大的情况下使用临时牙桥可能会发生断裂。开发一种不需要特殊设备就能在临床就诊时加固临时修复体的简单方法，是一项紧迫的科学和实践任务。研究目的本研究的目的是根据不同的丙烯酸树脂和双丙烯酸树脂，评估玻璃纤维加固和非加固短跨度和长跨度临时牙桥的应力分布。研究方法。为此，开发了四个有限元模型，以再现修复材料和硬质牙体组织的特性（杨氏模量、泊松比、硬度）。每个模型均承受 100 牛顿的垂直荷载，荷载施加在牙桥中部。计算在 APM 3D Studio 中进行，所得结果在 Ansys 12.2 中进行监控。所得结果显示在显示器屏幕上，并进行打印和分析。结果。丙烯酸无加固短跨度桥（模型 1）的应力分布图显示，咬合面区域的应力最大（4.2-5.2 n/mm2）。丙烯酸树脂非加固大跨度桥体（模型 2）的应力分布图显示，负荷区和面向缺损的连接体颈区的应力最大（11.4-12.3 n/mm2）。丙烯酸加固大跨度桥梁（模型 3）的应力分布模式显示，纤维加固带位于桥梁深处的区域应力最大（10.5-12.0 n/mm2）。双丙烯酸加固大跨度牙桥（模型 4）的应力分布模式显示，玻璃纤维加固带所在区域和咬合面的应力最大（9.8-10.5 n/mm2）。结论有限元分析证实了用玻璃纤维加固丙烯酸或双丙烯酸树脂制作的大跨度临时牙桥的可行性。

Objective. To study the dental pathology frequency and structure of clinical polymorphism among respondents in adolescence and 1st period of adulthood studying at universities in Stavropol. Methodology. 508 respondents aged 17–35 years according to the Gurov V.A. (2018) classification of human age periodization were examined clinically, by questionnaire and 3D-biometrically. Therapeutic, orthopedic, orthodontic and gnathological complaints were identified when filling out the proposed express dental health card for a first-year students. Using virtual dynamic 3D-reformats of diagnostic jaw models, the types of occlusal relationships of dentitions and the types of dentitions shape anomalies (V-shaped, saddle-shaped, triangular, trapezoidal, asymmetrical) with a distal relationship were determined. Results. The dental pathology frequency of occurrence and structure of clinical polymorphism in respondents of adolescence and 1st period of adulthood with complete and incomplete dentitions were diagnosed in descending order as follows: anomalies of occlusion without gnathological disorders, various localization defects of dentitions, anomalies of occlusion with gnathological disorders, defects of dentitions with anomalies of occlusion, defects of dentitions with gnathological and occlusal disorders and defects of dentitions only with gnathological disorders. The structure of occlusion anomalies was diagnosed in descending order as follows: distal occlusion, cross occlusion, mesial and vertical incisal occlusion. Physiological occlusion was the least during the study. Conclusion. Structured data from questionnaires, clinical examinations and 3D-biometric data from shape analysis of the virtual dynamic 3D-reformats of diagnostic jaw models can be used in conducting epidemiological studies, simplifying diagnosis, prognosis, archiving and increasing the efficiency of complex dental treatment.

Introduction. Anticoagulant therapy is prescribed for surgical interventions in the heart and blood vessels, atrial fibrillation, thromboembolism and thrombophlebitis of various etiologies, myocardial infarction, new coronavirus infection. This group of patients is characterized by a decrease in physical and social activity, and motivation to care about their own health. As a result, poor oral hygiene can cause gum bleeding, which is often mistaken for a side effect of the anticoagulant being taken. Without proper attention, the process risks moving into severe stages of the development of periodontitis, which has a direct impact on the course of cardiovascular diseases. Maintaining a level of personal oral hygiene is especially important. An additional tool, in addition to a toothbrush and toothpaste, is an irrigator - a device that creates a pulsating stream of water, which under pressure washes and removes food debris and soft plaque. Aim. To evaluate the effect of the irrigator on the severity of inflammatory processes in periodontal tissues in patients on anticoagulant therapy. Methodology. 30 patients were examined (15 using warfarin, 15 using new oral anticoagulants) according to the following criteria: complaints of bleeding gums, degree of gum bleeding according to Mullemann, hygiene index, objective periodontal index (OPI – patent No. 265521 of 2018). Signs were assessed by statistical methods before professional oral hygiene and after 1.5 months of using irrigators OMIO-350, OMIO-450, OMIO-560 to maintain personal hygiene and prevention. Results and its discussion. After using the irrigator, complaints of bleeding gums remained in 4 patients out of 16 examined. The average hygiene index decreased by 48.7%, the objective periodontal index decreased by 42.9%. In most patients, bleeding disappeared or decreased in intensity. Conclusions. The positive effect of irrigators, as an additional means of personal hygiene, on periodontal tissue and improvement of oral health in patients has been proven.

Item. The review of literature devoted to the actual problem of maxillofacial surgery — processes of bone tissue regeneration in mandibular fractures is presented. The purpose of the study — to study and analyze the materials of publications on the processes of bone tissue regeneration in mandibular fractures. Methodology. The publications of domestic and foreign authors devoted to the processes of bone tissue regeneration in mandibular fractures were studied. The publications were analyzed using scientific search library databases: PubMed Central, Google, Cyberleninka, eLibrary. Materials were selected by keywords. Full-text articles were included in the search. Results. In domestic and foreign literature, the processes of restoration of bone structures of the maxillofacial region as an organism's response to damage have been studied and described in detail. It has been established that two processes are simultaneously launched: resorption of damaged osteocytes and formation of osteoid tissue, one of which may be predominant at the moment. Conclusions. The article presents modern data on the key moments of bone tissue regeneration in the region of the mandible. All stages of the reparative process in bone tissue are described at the cellular level, and information about the main mechanisms, pathways and cell types involved in bone tissue regeneration is presented in detail, taking into account the stage of osteogenesis. Knowledge of the regularities of biological processes in the bone tissue regeneration zone allows scientific search and development of effective methods of treatment of mandibular fractures.
