К вопросу о палеопатологических особенностях населения V–VII вв. н.э. с территории Волго-Донских степей

The paper presents the results of the paleoanthropological materials study of the 5th – 7th centuries originating from under the kurgan mounds and ground burials located in the Volga-Don steppes territory. Eleven skeletal remains of 8 men, 2 women, and 1 child were studied. The data obtained as a result of the paleopathological analysis of the material dating back to the post-Hunnic-early Turkic period have been introduced into scientific circulation for the first time. In the course of the paleoanthropological material analysis, analogies with nomadic cattle breeding groups residing on this territory in the Bronze Age, Early Iron Age, and Late Middle Ages have been established in terms of gender, age, and pathological indicators. The findings were confirmed despite the small number of the analyzed series. In adult individuals, a number of dental conditions were recorded, indicating that viscous foods rich in fats and proteins had dominated the diet of the early Turkic time population. The mobile lifestyle of the Volga-Don steppes population of the 5th – 7th centuries was reflected on the skeletal remains of the studied individuals in the form of stress indicators associated with horse riding and body exposure to low temperatures. The presence on a number of skulls of the studied group of traces of the use of deliberate artificial deformation allows us to make the assumption that they had traditions that were characteristic of the nomads of the Eastern European steppes of the first centuries of our era.

CVApool: using null-space of CNN weights for the tooth disease classification

In light of current developments in dental care, dental professionals have increasingly used deep learning methods to get precise diagnoses of oral problems. Using intraoral X-rays in dental radiography is imperative in many dental interventions. Integrating deep learning techniques with a unique collection of intraoral X-ray images has been undertaken to enhance the accuracy of dental disease detection. In this study, we propose an alternative pooling layer, namely the Common Vector Approach Pooling technique, to address the constraints associated with average pooling in deep learning methods. The experiments are conducted on a large dataset, involving twenty different dental conditions, divided into seven categories. Our proposed approach achieved a high accuracy rate of 86.4% in identifying dental problems across the seven oral categories.

Preventive dental care reduces risk of cardiovascular disease and pneumonia in hemodialysis population: a nationwide claims database analysis

This study aims to investigate the impact of dental care utilization status on the occurrence of fatal complications such as cerebral/cardiovascular disease (CVD) and infectious diseases in patients with end-stage renal disease (ESRD) undergoing hemodialysis. This retrospective cohort study was performed using the Japanese claims database and included patients who first underwent hemodialysis between April 2014 and September 2020. The exposure variable of interest was the pattern of dental utilization, which was categorized into three groups, “dental treatment group”, “preventive dental care group”, and “no-dental visit group”. The primary outcomes were the time interval until a composite end point of first major cardiovascular event (acute myocardial infarction, heart failure, or cerebral infarction) of infectious disease (pneumonia and sepsis). The secondary outcomes were the time interval until the incidence of each component of primary outcomes. Survival analyses, including log-rank tests and Cox proportional hazards regression analyses, were performed. Among the 10,873 patients who underwent the first dialysis treatment, 6152 were assigned to the no-dental visit group, 2221 to the dental treatment group, and 2500 to the preventive dental care group. The preventive dental care group had significantly lower hazard ratios (HRs) of the incidence of CVD (adjusted hazard ratio [aHR]: 0.86, 95% confidence interval [CI]: 0.77–0.96) and infectious diseases (aHR: 0.86, 95% CI: 0.76–0.97). As for pneumonia, preventive dental care and dental treatment groups had significantly lower HRs (aHR: 0.74 and 0.80, 95% CI: 0.61–0.88, 0.66–0.96) than the no-dental visit group. This study demonstrated that dental visits for preventive dental care were associated with a significant risk reduction in CVD and infectious complications in patients with ESRD undergoing hemodialysis.

Regular dental check-up status and related factors among Thai residents in Japan.

The objectives of this online study were to determine the status of regular dental check-ups among Thai nationals living in Japan and to identify barriers to regular dental check-ups by comparing them with general health check-ups. We conducted the online survey twice, in 2021 and 2022, among Thai nationals aged 18years and older living in Japan via social networking services by an organization that supports Thai nationals living in Japan. Respondents between the ages of 30 and 59 were included in this study. Independent factors included gender, age, length of stay in Japan, family economic status, confidence in Japanese and stay for work purposes. Dependent factors were regular dental check-ups and general health check-ups in the past year. Chi-square tests and multiple logistic regression analyses were used for analysis. 56.6% of respondents had regular dental check-ups. The adjusted odds ratio for the proportion of people with regular dental check-ups was significantly higher for those with high economic status, 2.15 (1.06-4.33), compared with those with low economic status. It was also significantly higher 1.88 (1.10-3.21) for those with confidence in the Japanese language compared with those without. The study suggested the need for Japanese language support in addition to financial support for dental health prevention programs for foreigners living in Japan.

Association between oral health and cognitive impairment in older adults: Insights from a Six-year prospective cohort study

ObjectiveThis study aims to investigate the relationships between four baseline oral conditions (periodontal status, dental caries, tooth wear, and dentition) and repeated global cognition or domain-specific cognition (memory, executive function, attention, and verbal fluency) in non-demented older adults over time. MethodsThis prospective cohort study (2011–2019) enrolled 516 non-demented community-dwelling older adults (age ≥ 65) to explore the association between oral health and cognitive function. Global and domain-specific cognition were assessed biennially (four repeats) using a battery of neuropsychological tests. The baseline oral health conditions were examined, including periodontal status, dental caries, tooth wear, and dentition. The association of these oral conditions with cognition was evaluated by generalized linear mixed models. Stratified analyses were performed by important covariates. ResultsOver time, dental caries was associated with poor memory in two different logical memory tests (β^= -0.06 and β^= -0.04). Incomplete dentition with less than 28 teeth was associated with poor performance in attention (β^= -0.05) and verbal fluency (β^= -0.03). These associations became more evident in those with an elevated inflammatory marker (IL-6, β^= -0.11 to -0.08). In contrast, tooth wear was associated with better memory in two different logical memory tests (β^= 0.33 and β^= 0.36) and better executive function (β^= 0.06) over time, and this association became more evident in those with the lowest inflammatory marker (IL-6, β^= 0.10). ConclusionsDental caries and incomplete dentition were associated with poor memory, attention, and verbal fluency performance. Conversely, tooth wear was associated with better memory performance and executive function. Clinical SignificanceFor early prevention of dementia, an evaluation of multiple dental and periodontal status in older adults helps predict the risk of dementia in the preclinical phase. Maintaining intact tooth structure without caries progression and eventually tooth loss may help prevent the worsening of memory, attention, and verbal fluency over time.

The objective of present work is to formulate and evaluate herbal mouthwash and to evaluate its effectiveness against microbial load of oral cavity. The plant materials were collected and extracted for water soluble ingredients. Prepared mouthwash was further evaluated for its physicochemical properties and antimicrobial activity. The present mouthwash possesses a good antibacterial property. The results of stability study also confirm the effectiveness of preparation. Present mouthwash is a liquid preparation which normally contains antibacterial and antiseptic agents. Commercially available mouthwash formulations are often medicated and contain chemicals that may elicit adverse effects to the users. A mouthwash may be recommended for its efficacy in preventing dental caries other oral conditions due to its antimicrobial, anti-inflammatory properties

DENTAL AND ORAL HEALTH COUNSELING FOR ELEMENTARY SCHOOL STUDENTS IN NGGELA VILLAGE

Children are still in a period of growth and development. Therefore, efforts to maintain oral health and dental health are critical, especially in the school and preschool environment. The development of dental health in adulthood is influenced by past dental conditions. Through counseling programs, communities can actively contribute to increasing their self-defense efforts and better understand the importance of maintaining their oral and dental health. This study aims to educate children about the importance of maintaining oral and dental health. Thus, children who receive counseling will better understand oral health.

Strategic Analysis of Feature Selection Methods for Enhanced Dental Therapy Recognition in Machine Learning Applications

The popularity of smart clinics has increased significantly as a result of technical developments in fields like computer vision. At the heart of such systems is the ability to recognize objects and activities as well as perceive the environment as a whole. This is crucial for both eco-independent systems and human-machine interaction, especially in settings with constrained workspaces, like dental care. Our study delves into an extensive analysis of multiple machine learning models designed to robustly predict dental treatments. These models encompass Lazy Instance-based Learning, Sequential Minimal Optimization, Hoeffding Tree, and Random Tree. Leveraging object-oriented input sourced from gaze-guided wearable cameras, we scrutinize intricate attributes such as material properties, patients' dental conditions, and the array of instruments in use. Notably, we exploit the insight that identifying visual cues during an activity holds the potential to address the specific therapy identification challenge. Utilizing a dental data set that we gathered in the real world, we conducted our experiments and discovered that combining multiple criteria enhances accuracy in comparison to using each one alone. We did see, nevertheless, that in certain circumstances employing the symptoms alone produced superior outcomes. Additionally, symptoms demonstrated to have lesser error than combination in terms of RMS error convergence. Finally, we observed that the machine learning models' build and test durations increased as a result of the combined method. This demonstrates that adding additional parameters does not necessarily result in better outcomes in machine learning applications generally and in medical/dental applications in particular. Instead, it relies on the machine learning tool used, the settings taken into account and the input data provided. The versatility of our approach extends beyond dental contexts. It has been systematically validated across diverse domains, including the recognition of kitchen activities within smart home environments. This methodology holds relevance for various outdoor scenarios where the focal point of attention guides ongoing activities.

German guidelines for airway management 2023.

The German airway management guidelines are intended to serve as an orientation and decision-making aid and thus contribute to the optimal care of patients undergoing anesthesiologic- and intensive medical care. As part of the pre-anesthesiologic evaluation, anatomical and physiological indications for difficult mask ventilation and intubation shall be evaluated. This includes the assessment of mouth opening, dental status, mandibular protrusion, cervical spine mobility and existing pathologies. The airway shall be secured while maintaining spontaneous breathing if there are predictors or anamnestic indications of difficult or impossible mask ventilation and/or endotracheal intubation. Various techniques can be used here. If there is an unexpectedly difficult airway, avideo laryngoscope is recommended after unsuccessful direct laryngoscopy, consequently avideo laryngoscope must be available at every anesthesiology workplace. The airway shall primarily be secured with avideo laryngoscope in critically ill- and patients at risk of aspiration. Securing the airway using translaryngeal and transtracheal techniques is the "ultima ratio" in airway management. The performance or supervision of airway management in the intensive care unit is the responsibility of experienced physicians and nursing staff. Appropriate education and regular training are essential. Clear communication and interaction between team members are mandatory before every airway management procedure. Once the airway has been secured, the correct position of the endotracheal tube must be verified using capnography.

The effectiveness of a self-reported questionnaire on masticatory function in health examinations.

Periodontal diseases have been reported to be lifestyle-related and associated with metabolic syndrome (MetS). The introduction of dental checkups in a health checkup program may create a synergistic effect and aid the prevention of MetS. In Japan, a chewing function questionnaire has now been introduced into the national health checkup program. The purpose of this study was to investigate whether the questionnaire reflects dental and oral conditions and whether it helps improve general and oral health. A total of 6599 subjects who underwent health checkups or guidance specified by the National Health Insurance of Japan for two consecutive years were included. A single comprehensive question to evaluate masticatory function was asked. Medical and dental examinations and insurance data were collected and used for analysis. In terms of masticatory function during chewing, 82.3% of subjects experienced no problems, 17.3% experienced some difficulty, and 0.4% experienced severe problems. There was a significant relationship between the questionnaire response and dental examinations results for several items of examination. The overall dental consultation rate after health screening was 42.3%. Improvement in periodontal disease was achieved in those who reported some problems with chewing function. Improvement in blood pressure was also observed in those who reported some problem with chewing function and subsequently had a dental consultation. The results of this study indicate that questionnaires on masticatory function reflect the status of dental and oral health. In addition, the results suggested that questionnaire results are potentially linked to improvement in dental and oral health status, and improvement in MetS.

Structural and Functional Characteristics of the Oral Cavity Organs and Tissues in Workers of the Petrochemical Industry of the Republic of Uzbekistan.

Purpose: The aim of the study was to determine the dental status, level, and structure of dental diseases, as well as to identify some clinical and functional deviations in the organs and tissues of the oral cavity among workers in certain industrial enterprises. Methodology: A comprehensive dental examination was conducted on 1600 individuals, including 420 from the Fergana Oil Refinery Plant (FNPP - main group (MG)-1), 425 from the Almalyk Mining and Metallurgical Plant (AGMK - MG-2), and 605 from the Navoi Chemical Plant (NavCP - MG-3), as well as 150 patients as a control group (CG) who visited a dental clinic. Tooth sensitivity (TS), pain and discriminatory sensitivity (PS and DS) of the oral mucosa, taste perception threshold, and functional mobility of the taste receptors on the tongue, enamel resistance to caries, microhardness (MH) of enamel and dentin, and the condition of periodontal tissues and pH of mixed saliva were determined. The data obtained were processed using statistical methods. Findings: It was determined that the levels and relative weights of the main dental diseases among workers in the studied industries remain quite high; carious and non-carious lesions of the tooth hard tissues, deformation and defects of teeth and dental rows (18.5%), periodontal tissue diseases (74.7%), diseases of the oral mucosa - 38.7%; the need for prosthetics (58.4%) and other pathologies. Additionally, almost all clinical and functional indicators and local non-specific reactivity of the tissues of the oral cavity in workers were disrupted. Unique Contribution to Theory, Policy and Practice: The presence of the main dental diseases among those surveyed from the studied groups is quite high, with noted reductions in the excitability threshold of teeth, around tooth tissues and the oral mucosa, disruption of PS and DS of the oral mucosa, as well as deterioration of the condition of tooth hard tissues. Based on the obtained results, the authors suggest continuing in-depth scientific research with the aim of developing effective methods for the diagnosis and prevention of dental diseases among workers in these industries.

Current Strategies for Treatment of Mandibular Fractures With Plate Osteosynthesis: A European Prospective Study.

The training and preferences of surgeons influence the type of surgical treatment for mandibular fractures. This multicentre prospective study analyzed the current treatment strategies and outcomes for mandibular fractures with open reduction and internal fixation (ORIF). This prospective study included patients aged ≥16 years who underwent ORIF for mandibular fractures in 12 European maxillofacial centers. Age, sex, pretrauma dental status, fracture cause, site and type, associated facial fractures, surgical approach, plate number and thickness (≤1.4 or ≥1.5mm), duration of postoperative maxillomandibular fixation, occlusal and infective complications at 6 weeks and 3 months, and revision surgeries were recorded. Between May 1, 2021 and April 30, 2022, 425 patients (194 single, 182 double, and 49 triple mandibular fractures) underwent ORIF for 1 or more fractures. Rigid osteosynthesis was performed for 74% of fractures and was significantly associated with displaced ( P =0.01) and comminuted ( P =0.03) fractures and with the number of nonsurgically treated fracture sites ( P =0.002). The angle was the only site associated with nonrigid osteosynthesis ( P <0.001). Malocclusions (5.6%) and infective complications (5.4%) were not associated with osteosynthesis type. Rigid osteosynthesis was the most frequently performed treatment at all fracture sites, except the mandibular angle, and was significantly associated with displaced and comminuted fractures and the number of nonsurgically treated fracture sites. No significant differences were observed regarding postoperative malocclusion or infections among osteosynthesis types.

РАЗРАБОТКА НОВОЙ КОНСТРУКЦИИ АРМИРОВАННОЙ ОККЛЮЗИОННОЙ ШИНЫ С ПАРАМЕТРИЗОВАННЫМ КАРКАСОМ НА ОСНОВЕ МЕДИЦИНСКИХ И ИНЖЕНЕРНЫХ ЦИФРОВЫХ ТЕХНОЛОГИЙ

Subject. Today, the use of splint therapy is an essential part of specialized dental treatment, since in recent years the number of patients with dysfunctional conditions of the dentofacial apparatus, has increased significantly. In addition, according to recent research, the use of occlusal splints as part of complex therapy is effective in the treatment of neurological diseases, such as bruxism, chronic tension-type headache, and neuromuscular syndrome. Traditionally used designs of occlusal splints have some disadvantages, such as fragility of use, insufficient rigidity, and the impossibility of relining if the patient's dental status changes. The article provides a description and clinical and laboratory stages of manufacturing the developed new design of an occlusal splint reinforced with a titanium frame. Objectives. Increasing the effectiveness of treatment of patients with functional disorders of the dentofacial system through the development and implementation of a new prosthetic construction – a combined occlusal splint with a titanium frame, using modern intellectual and medical 3D technologies. Materials and methods. Titanium alloy (Rematitan®) was chosen as the material for the frame of the occlusal splint. Manufacturing method implies the use of additive technologies, in particular, 3D-printing for obtaining a high-precision structure with a minimum cross-sectional thickness. Hot-curing acrylic plastic was used to cover the parameterized frame; it is also possible to use a light-curing composite. Results. During the study, the expediency of introducing a reinforcing component in the form of a metal frame into the construction of the occlusal splint was determined. A new design of a combined occlusal splint and a method for its manufacture were developed. Conclusion. By reinforcing the occlusal splint with a titanium frame, high structural strength, durability of use, maintainability or relocation if necessary are ensured; at the same time, due to 3D-printing, the frame has a minimal cross-sectional thickness, which practically does not affect the thickness of the structure as a whole.

Dental status of children of early and preschool age in Moscow

INTRODUCTION. Conducting an epidemiological survey allows us to obtain reliable initial data on the level of prevalence and intensity of dental diseases, identify priority needs for providing all types of dental care to children, plan and implement dental programs, focusing on the initial dental status of the child population at different age periods.AIM. To study the dental status of children of early and preschool age based on data from a cross-sectional epidemiological study.MATERIALS AND METHODS. A cross-sectional epidemiological survey of the child population was conducted as part of preventive medical examinations of minors to study the dental morbidity of children of early (1–3 years) and preschool (4–6 years) age in Moscow. The study involved 1470 Moscow children aged 1 to 6 years old. The results of the survey were processed statistically.RESULTS. Data analysis showed that the indicator of the need for oral sanitation tends to increase as children grow older. A statistically significant dependence of the need for rehabilitation on the age group was revealed. The indicator of previously sanitized children is variable at different age periods. The rate of natural sanitation decreases as children grow older. A statistically significant dependence of natural sanitation on the age group was revealed. Categorical variables (absolute and relative) of the need for sanitation are higher among girls in all age groups and lower among boys. But statistically significant differences in the need for sanitation in boys and girls were observed only in the age group 1 year, 3 years and 5 years. In the age groups of 2, 4 and 6 years, there was a similar need for sanitation among boys and girls; no statistically significant differences were identified, despite the fact that categorical variables (absolute and relative indicators) indicated a higher need for sanitation of the oral cavity in girls than boys.CONCLUSIONS. Categorical (absolute and relative) variables indicate that the need for oral sanitation in girls is higher than in boys at all age periods.

Evaluation of the accuracy of seven intraoral scanners for the full dentate and partially edentulous complete-arch mandibular casts: An in vitro comparison

Statement of problemIntraoral scanners (IOSs) are widely used in dentistry, providing high accuracy in short-range scanning. Nevertheless, when scanning the full dental arch, it remains a challenge. Furthermore, there is a lack of studies reporting the differences in scan accuracy between dental arches with large-span mucosal areas and fully dentate casts or optimal IOS selection for different dental statuses. PurposeThis study aimed to evaluate the accuracy and scanning time of different IOSs for full dentate (FD) and partially edentulous (PE) casts with missing teeth in the #34–#44 range and to determine the IOSs with the optimal clinical adaptability and scanning accuracy for different complete-arch casts. Material and methodsReference scans of two complete-arch (FD and PE) casts were obtained using a laboratory scanner (Ceramill Map 600). Subsequently, the same casts were scanned ten times each by seven IOSs (3Shape Trios 3, CS3600, Planmeca Emerald, iTero Element 5D, Medit i500, BAMBOO B1, and Shining Aoralscan 3), and the scanning time was recorded. The test data were superimposed on the reference scans for the selected areas, and three-dimensional deviations between the reference and test casts (trueness), and between test casts (precision) were determined using reverse engineering software (Geomagic Wrap). The dataset was analyzed using a two-factor analysis of variance with post-hoc Bonferroni tests. ResultsTwo-factor analysis of variance revealed significant differences in accuracy and scanning time for different casts (P < 0.001) and IOSs (P < 0.001). For the FD cast, the i500 (0.35 ± 0.11 mm trueness) and CS3600 (0.23 ± 0.12 mm precision) performed worse than the remaining scanners. For the PE cast, the BAMBOO B1(0.89 ± 0.58 mm trueness; 0.88 ± 0.48 mm precision) performed worse than the remaining scanners. There were no differences in the accuracy of scanning between the Element 5D and Emerald for both cast types. However, the scanning time differed significantly between the different IOSs (P < 0.001). Regardless of the cast type, the fastest and slowest scans were performed by the Trios3 and CS3600 scanners respectively. ConclusionsThe accuracy and scanning time differed between the different IOSs and types of complete-arch casts.

Exploring the Benefits of Antioxidants in Dentistry: New Frontiers in Oral Care.

In recent years, antioxidants have gained significant attention in the field of dentistry due to their potential therapeutic benefits in various dental conditions. This comprehensive review aims to provide a detailed analysis of the role of antioxidants in dentistry, focusing on their mechanisms of action, clinical applications, and future prospects. The review highlights the potential of antioxidants in preventing and managing oral diseases, promoting oral health, and enhancing the outcomes of dental treatments.

A Systematic Review on the Role of Antibiotics and Analgesics in Systemically Ill Patients Undergoing Tooth Extraction.

Antibiotics are commonly prescribed as a preventive measure, particularly post-tooth extraction, aiming to minimize the risk of infection. Preemptive analgesia functions by disrupting the nervous system's ability to encode pain stimuli, thus preventing the formation of pain memory. Dentists often recommend analgesics and antibiotics either as adjuncts or sole treatments for various dental conditions, offering both efficacy and cost-effectiveness. A comprehensive literature search was conducted across multiple databases, including PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Science Direct, and Lilac, using MeSH terms relevant to the role of antibiotics and analgesics in systemically ill patients undergoing tooth extraction. Out of 178 articles screened, 83 underwent full-text assessment for eligibility, and six were selected for qualitative analysis. The review process adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, ensuring methodological rigor and transparent reporting. Across diverse study populations, the role of antibiotics and analgesics consistently demonstrated a statistically significant impact. Hence, the utilization of analgesics and antibiotics plays a pivotal role in preventing infection following tooth extraction in systemically ill patients, thereby promoting optimal oral hygiene and overall health.

Protocol for a Systematic Review and Meta-analysis of the Epidemiology of Early Childhood Caries in Nigeria

Abstract Background: Early Childhood Caries (ECC) is a prevalent dental condition among children under six years, characterized by tooth decay linked to microbial interaction with sugary substances. ECC poses significant health risks, including pain, infections, and tooth loss, impacting oral health and overall well-being. Objective: This systematic review and meta-analysis aims to comprehensively evaluate the epidemiology of Early Childhood Caries (ECC) in Nigeria. The study seeks to consolidate existing literature, assess study quality, and analyze data on ECC prevalence, distribution, and severity across different regions of Nigeria. Methods: Following Meta-Analysis of Observational Studies in Epidemiology (MOOSE) guidelines, databases including PubMed/MEDLINE, Cochrane, Scopus, and African Journals Online were systematically searched. Inclusion criteria encompass cross-sectional and cohort studies reporting ECC prevalence in healthy Nigerian children under six. Data extraction will utilize standardized protocols, focusing on WHO criteria such as dmft scores and caries severity. Quality assessment will be conducted using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Prevalence Studies. Results: Initial searches identified a scarcity of comprehensive studies, predominantly from southern Nigeria, highlighting the absence of national-level data on ECC in Nigeria. Data synthesis will explore geographic and demographic factors influencing ECC prevalence and severity, aiming to provide a holistic understanding of the disease burden. Conclusion: This review addresses the critical gap in ECC epidemiology within Nigeria, aiming to inform targeted interventions and policy decisions. By synthesizing available data, the study aims to contribute towards improving oral health outcomes among Nigerian children.

Linking orthodontic treatment and sleep apnea among adult Indian patients

The differences in the effects of orthodontic treatment on airway and craniocervical posture in patients with OSA (obstructive sleep apnea) having skeletal class II high-angle malocclusion is of interest. Hence, 48 individuals with OSA and skeletal class II high-angle malocclusion were chosen from among all patients in need of orthodontic therapy. Every patients had CBCT (cone beam computed tomography) taken both before and after receiving orthodontic therapy. All parameters were assessed on the lateral cephalogram from CBCT in order to assess the indices of craniocervical posture, hyoid position, skeletal and dental conditions. Parameters of upper airway (position of hyoid) showed statistically significant increase in values after orthodontic treatments. Thus, there was increase in values of dimensions of upper airway, post orthodontic treatment. Hence, orthodontic therapy help improve the upper airway morphology and craniocervical posture in patients of OSA with hyperdivergent skeletal class II malocclusion.

ВЛИЯНИЕ РЕВМАТОИДНОГО АРТРИТА НА ТЕЧЕНИЕ ЗАБОЛЕВАНИЙ ПАРОДОНТА

The most common chronic systemic autoimmune disease of connective tissue is rheumatoid arthritis, the incidence of which is up to 50% (in Russia). The etiology of rheumatoid arthritis is still not known for certain. Scientists pay special attention to searching and studying the factors influencing the occurrence of this disease. Researchers are interested in periodontitis as a likely factor in the development of rheumatoid arthritis. The literature presents limited data on the study of the characteristics of the course of dental diseases in patients with rheumatoid arthritis, which indicates the need for further study of this issue and clarification of the relationships between the intensity of caries, the condition of periodontal tissues and the temporomandibular joint in this category of patients. The study of these issues is of scientific and practical interest, as it allows us to improve the methods of diagnosis and monitoring of patients with rheumatoid arthritis by a dentist. The purpose of this study is to determine the effect of rheumatoid arthritis on the course of periodontal diseases. Materials and methods. The methodology of the scientific research is based on the analysis of domestic and foreign literature in the eLIBRARY databases; basic and additional methods of examining the patient were carried out. During the clinical examination, we assessed the general condition of the patient with rheumatoid arthritis, his dental and periodontal status. Results and discussion. A clinical examination of a patient with somatic pathology was carried out. Microorganisms of periodontal pockets were determined, the data obtained were compared with a patient who does not have a systemic disease. Conclusions. Patients with rheumatoid arthritis generally have a thin gingival biotype. Immunological parameters of oral fluid (IgA) in rheumatoid arthritis decrease, which indicates a lack of local and general immunity and leads to damage to periodontal tissue. In the future, this scientific research will help us develop optimal methods for diagnosing and treating patients with autoimmune disease.
