The prospects of using biopolymer nano-containing films for wound healing were substantiated. The main components of biopolymer composites are gelatin, polyvinyl alcohol, glycerin, lactic acid, distilled water, and zinc oxide (ZnO) nanoparticles (NPs). Biopolymer composites were produced according to various technological parameters using a mould with a chrome coating. The therapeutic properties of biopolymer films were evaluated by measuring the diameter of the protective effect. Physico-mechanical properties were studied: elasticity, vapour permeability, degradation time, and swelling. To study the influence of technological parameters of the formation process of therapeutic biopolymer nanofilled films on their therapeutic and physico-mechanical properties, the planning of the experiment was used. According to the results of the experiments, mathematical models of the second-order were built. The optimal values of technological parameters of the process are determined, which provide biopolymer nanofilled films with maximum healing ability (diameter of protective action) and sufficiently high physical and mechanical properties: elasticity, vapour permeability, degradation time and swelling. The research results showed that the healing properties of biopolymer films mainly depend on the content of ZnO NPs. Degradation of these biopolymer films provides dosed drug delivery to the affected area. The products of destruction are carbon dioxide, water, and a small amount of ZnO in the bound state, which indicates the environmental safety of the developed biopolymer film.

In the problem of solving diagnosis and treatment of hard tissue defects, a significant role is played by the choice of tactics for dental treatment of tooth decay. This work was aimed at studying the problem of diagnosis and systematization of hard tissues defects, that will contribute to the objectification of diagnostic and therapeutic approaches in dental treatment of patients with this disease. The objective of the research was to develop an anatomical and functional systematization for differentiated evaluation of tooth defects, as a basis for the application of differentiated diagnostic and therapeutic approaches to dental treatment of hard tissue defects. Materials and methods. For differential assessment of the extent of tooth defects and precise estimation of the strength of the composition “tooth-restoration”, we conducted   mechanical and mathematical modeling of contact interaction of restoration with dental tissues. We conducted anthropometric studies of all types of cavities of different groups of teeth as well.  Results. As a result of the study, there was proposed the systematization of hard tissues defects – location of defects, occlusive load, extent of defects/ depth of decay. The algorithm for choosing the method of treating hard tissues defects that is based on the systematization of location of defects, occlusive load, extent of defects/ depth of decay and may serve as a selection criterion for the treatment of such pathologies was offered. Conclusions. The proposed systematization filled the obvious gap in academic ideas of hard tissue defects, suggested the prospect of reaching a consensus on differentiated diagnostic and therapeutic approaches in treatment of patients with this disease building the methodological “bridge of continuity” between therapeutic and orthopedic dentistry in the field of hard tissue defect treatment.

The development of technologies transforms, develops, and improves old and creates new forms of human life organization, optimizing and modernizing them. Technologies also influence transformational changes in education and require the joint efforts and collective work of all educators, which necessitates updating approaches to organizing educational processes, determining the renewal of the educational space, and developing a modern educational environment characterized by technological saturation. One of the elements of the information and digital learning environment is the so-called digital (virtual) educational hub. Digital educational hubs can support any educational field, including the «Health care» sector. Learning during the pandemic and war has prompted us to create an online platform for self-education or an Education Hub based on the university website. The target audience of the hub includes students of the specialized medical college of Ivano-Frankivsk National Medical University in the field of knowledge 22 «Health Care», specialties 223 «Nursing», 221 «Dentistry», 226 «Pharmacy»; students of the medical and dental faculties of IFNMU, and students of other medical educational institutions. The Educational hub consists of a homepage that provides general information about the Professional Medical College, Ivano-Frankivsk National Medical University, the goals of the hub, and more. The next page, «Nursing» is designed for students of specialty 223 «Nursing». Virtual learning blocks have been created for students, which contain videos and algorithms for various manipulations, test tasks, materials for preparation for the Krok M exam, tactical medicine guides, and more. From the «Nursing» page, one can navigate to the «Dentistry» page, designed for students of specialty 221 «Dentistry» and the «Pharmacy» page, designed for students of specialty 226 «Pharmacy». As part of the cooperation between the professional medical college of the Ivano-Frankivsk National Medical University and the Andrey Krupinsky Lviv Medical Academy before the war, various events took place. The war has had an impact on our lives... However, our cooperation continues. During times of unstable electricity and constant anxiety for the implementation of academic mobility, we have used the Educational Hub. In particular, professors Natalia Tsubanova, Oleksandra Palahitska, and Natalia Rudakova from the Andriy Krupinsky Lviv Medical Academy posted a series of educational materials on the Educational Hub. Associate Professor Oleksandr Bulbuk (professional medical college of the Ivano-Frankivsk National Medical University) shared his educational materials on dentistry. This ensured free access and the establishment of organized learning opportunities, allowing all interested students from both educational institutions to participate in the educational process regardless of their location and time. The Educational Hub of the Professional Medical College of Ivano-Frankivsk National Medical University is an element of the information and digital learning environment that modernizes and enhances it, providing the development of the educational process in the field of "Healthcare". Additionally, this educational platform enables academic mobility for all participants of the educational process.

Background. Restoring large defects with proximal caries extending below the cemento-enamel junction and cavity margins located beneath the gingival tissues represents a very common clinical situation. The aim of this article is to propose a clinical classification of the localization subgingival margins of cavity.Material and methods. Diagnosis is carried out by periodontal probe perpendicular to the long axis of the tooth in the deepest point of the cavity’s margin. To describe the localization subgingival margins of cavity we use exponent which value is equal to the distance (integer number expressed in millimeters) of the level of epithelial attachment to the margin of the cavity. Three periodontal examiners, with >10 years of periodontal practice, were required to attend a calibration session aimed at the validation of the proposed classification. Results. The intrarater and interrater agreement among the localization subgingival margins of cavity: for intrarater agreement ranged from 0.74 to 0.95 (almost perfect agreement), whereas interrater agreement ranged from 0.26 to 0.59 (moderate agreement).Conclusions. The classification the localization subgingival margins of cavity is useful for reaching a more precise diagnosis.

Попередні дослідження встановили, що зі збільшенням об'єму дефекту твердих тканин зуба, збільшується чутливість відновленої структури до фізико-механічних характеристик реставрації. Оскільки існуючі методики визначення об'ємів неможливо використати в клінічних умовах, це дає підстави вважати проблему визначення величини об'єму дефектів твердих тканин зуба надзвичайно важливою, тому наше дослідження є актуальне.Мета дослідження. Розробити та оцінити можливість використання методик визначення об'ємів коронок зубів і об'ємів дефектів твердих тканин зубів.Матеріали і методи дослідження.
