Study the available specialized literature on the use of CBCT in maxillofacial imaging and the combination of this research method with artificial intelligence to improve the diagnosis and treatment of complex dental diseases. \u0000Methodology. The data of special literature were studied using scientific search library databases: Pub Med, Elibrary, Cochrane, Google Scholar. \u0000Results. The use of cone-beam computed tomography (CBCT) in the examination of patients in need of prosthetics allows to obtain a large amount of diagnostic information about the condition of hard tissues of teeth, bone tissue of jaws, temporomandibular joint and nearby anatomical structures in comparison with other radiological methods of additional examination of patients. The possibilities of this type of research were evaluated together with a representative of the \"Diagnocat\" artificial intelligence system and an analysis of its advantages was carried out. It also describes a comprehensive protocol for planning orthopedic treatment of patients based on digital (virtual) modeling and its advantages for a practicing orthopedic dentist. \u0000Conclusions. The CBCT method is widely used in modern dental practice due to its accuracy, accessibility and high objectivity. Artificial intelligence technologies introduced into the planning process of complex dental treatment are gradually becoming a tool for the practitioner. Automatic recognition of teeth and diagnostics of facial deformities using artificial intelligence systems based on CBCT are very likely to become an area of increased interest in the future. The review is aimed at giving practicing dentists and interested colleagues in the field of healthcare a comprehensive understanding of the current trend in the development of artificial intelligence in the field of 3D visualization in dental medicine.","PeriodicalId":430676,"journal":{"name":"Actual problems in dentistry","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128977272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The age of patients in these groups was 60–74 years, which corresponds to an elderly age. The control group included 20 healthy volunteers under the age of 40. The content of tumor necrosis factor (TNF), interleukin-6 (IL-6), and protein p53 were determined in the oral fluid. The concentration of these proteins was determined by multiparametric fluorescence analysis with magnetic microspheres (xMAP technology, Luminex 200, USA) using the ProcartaPlex Apoptosis 6-Plex Human ProcartaPlex ™ Panel and ProcartaPlex test systems Human Cytokine/Chemokine (Invitrogen, USA). According to a number of authors, these parameters indirectly characterize the processes of cellular aging. We have identified laboratory markers of oral fluid characteristic of age-associated syndromes, for occlusive syndrome it is salivary TNF, for inflammatory periodontal – TNF and possibly IL-6, for dystrophic syndrome – protein p53. In addition, a correlation was found between age and the severity of the process.

In this regard, the task of searching for highly informative markers, both morphological and laboratory, as well as molecular genetic markers, remains extremely relevant, allowing predicting the risk of developing periimplantitis in various populations. An equally urgent task is the search for effective means of adjuvant therapy and prevention of inflammatory complications after dental implantation. The aim of this study was a comprehensive histopathological assessment of the state of the gingiva by biopsy at the stage before implantation in a clinical case series. \u0000In a clinical case series (25 patients), using a descriptive histological method, a histopathological analysis of gingival biopsy samples obtained at the stage of implant placement was performed. The data of the descriptive histological analysis were supplemented by the results of an immunohistochemical study for the expression of vitamin D receptors (VDR) in the gingival tissues and inflammatory infiltration cells. \u0000According to the results of a descriptive histopathological analysis, in 7 out of 25 cases (28%) in the gingival tissues of the edentulous area of the jaw in the area of the included defect of the dentition, the phenomenon of less or more pronounced chronic inflammation was revealed, manifested in lymphocytic or mixed lymphohistiocytic infiltration. Other significant histopathological changes were presented by the changes in the gingival epithelium, as well as disorders in the vessels of the microvasculature. Immunohistochemical analysis demonstrated the presence of a strong nuclear and/or cytoplasmic expression of VDR both in the epithelium and cells of the inflammatory infiltrate, regardless of the age and gender of the patients or the severity of inflammatory changes in the gingival tissues. \u0000The results of the pilot analysis of clinical case series are of interest for further study of pre-implantation gingival or periodontal lesions, and may help identify biomarkers of the subsequent development of periimplantitis, as well also provide a fundamental rationale for the use of vitamin D as a prophylactic or therapeutic adjuvant.","PeriodicalId":430676,"journal":{"name":"Actual problems in dentistry","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126321924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Creating high-quality interdental contacts is the most important and difficult step in the treatment of proximal caries. In modern dentistry, most methods for restoring the proximal wall of teeth involve the use of dental matrices. The choice of matrix and the peculiarities of working with it are the determining factor in the formation of the proximal contour of the tooth and often causes difficulties, especially for young specialists. \u0000The aim of the study is to conduct an experimental-mathematical determination of the tensile strength of dental matrices to elastic deformation based on the curvature of the proximal surface of the chewing teeth. \u0000Materials and methods. The work consisted of 2 stages. Initially, a test bench was developed to assess the deformation capabilities of dental matrices, consisting of a strain gauge and a model of the proximal tooth wall with the possibility of fixing the matrix and imitating pushing. The model was created in SolidWorks software and 3D printed from light-cured polyamide. At the second stage, computer models of teeth and matrices were created, as well as an analysis of data from x-rays and other sources. \u0000Results. In the course of the work, the strength characteristics of dental matrices were obtained, the limits of their deformation capabilities were determined depending on the thickness of the material and the area of impact on it. Titanium matrices have the best strength characteristics, withstanding a force of 70 N, with an impact area of 2.25 mm2. An analysis of the curvature of the proximal surfaces of the chewing teeth revealed the best match between the matrix contour and the tooth contour on the medial surface of the first molars of the upper and lower jaws. \u0000Conclusions. To achieve high results in the restoration of the proximal walls of the teeth, in most cases it is recommended to press the matrix with an instrument with a working area of at least 2 mm2.","PeriodicalId":430676,"journal":{"name":"Actual problems in dentistry","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133858448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main method of influencing the patient is individual preventive counseling. Hygienic education and upbringing should be strictly differentiated by purpose and content, depending on the age of children. However, pediatric dentists have difficulties in teaching the patient and their parents hygiene skills. For example, this may be due to the lack of free time for parents to listen to information from a doctor about the prevention of dental diseases. Parents receive information from the Internet and social groups without thinking about the correctness of the information received and the availability of a scientific approach. The authors have developed a software product for patients of dental medical organizations of children's profile, in which the space is divided by age: from 0 to 17 years. \u0000Conclusions. Despite the scaling up and implementation of preventive measures, the intensity of caries and its increase in many regions of the Russian Federation is at a fairly high level. The lack of information received at the clinical reception, the psycho-emotional component of the child's behavior, the lack of a scientific approach in the Internet information networks lead to low effectiveness of prevention programs. That is why one of the main directions in healthcare is the prevention of diseases, as well as the formation of a healthy lifestyle for both adults and children. The use of the developed product provides various advantages both for the dental medical organization and for patients and their parents.
