This article substantiates the structure of the author’s concept of training future pediatric dentists by means of situational-communicative models of professional interaction. The author’s concept combines several spheres of activity of subjects of scientific research: medical since the organization of the scientific research process concerns representatives of the field of health care; stomatological since the target aspect outlines the training of future dentists, whose professional activity is concentrated in the system of pediatric dentistry; educational, aimed at updating dental education in medical institutions of higher education due to the use of modern pedagogical technologies and is therefore considered as a pedagogical concept. The conception consists of five concepts and reflects the sequence, phasing and logic of scientific research. The essence of actuality-argumentative, prospective-innovative, scientific-methodological, methodical-providing and analytical-resultative concepts of research and experimental work has been concretized. The conception takes into account the integrability of various directions of scientific research. The expediency of modernizing the professional training of future pediatric dentists for the formation of readiness for professional interaction is argued, focusing attention on progressive changes in the system of higher medical education. The views of researchers regarding the necessity to improve the professional training of students, taking into account the diversity of education of future pediatric dentists, are summarized. The scientific and methodological justification of scientific research in the context of research is highlighted. The need for methodical maintenance of the practical aspect of experimental work and proving the reliability of the obtained results is substantiated. The presence of integration of all defined concepts in a holistic author’s concept of training future pediatric dentists by means of situational-communicative models of professional interaction is emphasized.

Abstract. The conducted study aimed for the integration of cloud technologies into the educational process to evaluate their influence on different aspects of the professional competence of future doctors. For this, methods of comparative analysis, questionnaire, expert assessment, observation and statistical analysis were used. Results showed that students of the experimental group demonstrated significant improvement in the professional competence of such components as cognitive, motivational-volitional and organizational performance aspects. This confirms the importance of the skill to effectively use digital technologies in both professional and personal life spheres. The use of cloud technologies such as Google Docs, Pbwiki, Sway, Microsoft Azure, and Microsoft Planner led to significant improvements in students’ results. Still, at the beginning, many teachers doubted these tools, although their attitude changed with time. Thus, reconsideration of educational programs to ensure their compliance with world education standards, in particular through the integration of new technologies, contributing to the development of professional competencies is relevant. The scientific novelty of the research is stipulated by the insufficient number of studies devoted to the use of cloud technologies in training future doctors.

Abstract:Theaim of the article is to determine the effectiveness of simulation training for the development of critical thinking in medical students. The Starkey’s Critical Thinking Test and specialized observation of the critical thinking of doctors in their professional activities were used to check the levels of the studied parameters. The initial diagnostics showed a predominance of low indicators of the general critical thinking of dental students. The medium and low indicators of the parameter were distributed almost equally in the sample of surgical students. The samples recorded a similar division of persons with low, medium, and high levels of critical thinking in professional activity. The delivered simulation training with interactive scenarios resulted in a slight increase in the general indicators of critical thinking in the experimental group (EG) of dental students. No significant dynamics of results for this parameter were recorded in other samples. Critical thinking in professional situations shows positive changes in all control groups (CG) and EGs as a result of simulation training. Therefore, it can be unequivocally stated that educational simulations are an effective tool for the development of clinical thinking. The implementation of interactive scenarios can provide an additional developmental effect. The obtained data enable making the development of professional competencies in medical students more effective. Further research may focus on studying the influence of simulation training on the critical thinking of medical students in other fields (therapeutic, traumatology, neurology, etc.).

   Aim: To investigate in an experiment the dynamic changes in the mandible bone following traumatic injury and subsequent defect replacement with an osteoplastic material - natural collagen.
   Materials and Methods: Experiments were conducted on 45 male rabbits aged 6-7 months, weighing 2.5-3.0 kg. The control group included 20 animals
with a bone tissue defect that healed under a blood clot. The experimental group consisted of 20 rabbits where the bone defect was filled with natural collagen (Col-C). Post-traumatic bone tissue status within the defect area was monitored for 84 days by The assessment of jaw macrostructure, radiographic examination, radiovisiography, examination of bone sections under a microscope, and lectin-histochemical analysis of decalcified bone sections.
   Results: A comprehensive examination of the experimental bone defect in the rabbit mandible, following implantation of natural collagen revealed extensive regenerative processes. These processes were observed at both the macroscopic and microscopic levels, corroborating the findings of radiographic and radiovisiographic analyses. Microscopic evaluation further elucidated the sequential nature of these regenerative changes and provided insights into the composition of the newly formed bone tissue.
   Conclusions: The application of the osteoplastic material (Col-C) demonstrated a high capacity to positively influence the processes of neo-osteosynthesis, followed by remodeling of the damaged bone. This ensures reliable functionality of the entire dentoalveolar system.

   Aim: to investigate the factors of bacterial virulence of oral microbiotopes against the background of long-term experimental action of an opioid analgesic.
Materials and Methods:The study was performed on 72 white outbred rats, which were injected “Nalbuphine” with a gradual increase in dose for 12 weeks.
The microbial composition and virulence factors of bacteria in the microbiotopes of the oral cavity were studied.
Results: At the end of the 4th week of opioid exposure, the appearance of hemolytic escherichia was noted. At the end of the 8th week the appearance of
capsular bacteria Klebsiella was registered, as a virulence factor. The production of staphylococcal virulence factors – lecithinase, was noted. At the end of the
12th week of opioid use, the appearance of phycomycete fungi was noted, Gram-negative diplococci, Klebsiella, Hemolytic Escherichia coli and Pseudomonas
aureginosa. These changes indicated the development of dysbiotic changes, as well as the gradual formation of foci of the inflammatory process in the oral cavity.
   Conclusions: In the short-term stages of opioid exposure, changes in biocenoses were manifested in an increase in the contamination of certain types of
microorganisms. In the long-term effects of the opioid, the activation of bacterial elements of the microbiocenosis was revealed, which were characterized by
increased expression of virulence factors. At the later stages of opioid exposure, the predominance of gram-negative microflora and the activation of cytotoxic action against the background of suppressed activity of the body’s protective response were established.
