Modern reconstructive methods of dentistry (stopping, restoration, and prosthetics with different types of orthopedic constructions) require detailed examination of the anatomical structure of the teeth crowns, especially examination of the knowledge about the relief of masticatory surface. That is why, we conducted a detailed examination of the features of odontoglyphics of molars, according to the sex and determination the odontometrical teeth indices of the citizens of Ternopil region. To achieve the goals, we use the following research methods, such as odontological, odontometrical, and statistical. According to the odontometrical indices of the sizes of the crowns of the molars, women’s processes of reduction are reflected more than men’s. Sex differences of the crown sizes are specially defined on the second upper and second lower molars. In the result of the conducted researches, it was found and theoretically confirmed racial identity of Ternopil and Ternopil region citizens, and it was given the characteristics of the differences of odontometrical indices of molar crowns of males and females. The lore of these characteristics plays a great role in the clinic of prosthetic dentistry.

Background: The rapid development of the dental industry and the daily practice of dentists necessitate constant learning because replenishing the stock of acquired knowledge and skills is the basis for the formation of a highly qualified specialist. Self-directed learning, especially reading and purposeful work with medical literature, constantly contribute to the development of thinking, which should correspond to the modern level of science in medical professionals in the context of the Covid-19 pandemic. The aim of the study was to monitor and analyze ways to obtain new scientific and practical knowledge by dentists to improve their dental practice. Materials and methods: The study involved 4.026 dentists who filled out for dentists online. Results: To improve daily dental practice, dentists additionally use information that is provided in lectures at scientific and practical events (80.19%) and Internet resources (71.48%). For dentists, the most convenient way to read scientific and practical articles was through the electronic version on the websites of the journals (62.20%). Informing doctors with articles with well-illustrated clinical cases (72.66%) and lectures along with practical materials (64.75%) are of the greatest interest to the vast majority of dentists. Conclusion: According to the analytical results, it is shown that the main ways of obtaining scientific and practical information for dentists in the process of self-directed learning is the active involvement of the materials gained on the lectures, scientific and practical events, from Internet resources, from scientific and methodological literature, from scientific articles of domestic and foreign English-language professional journals.

Background:In everyday clinical practice, patients who seek dental care in case of oral mucosa diseases are one of the most difficult categories of patients due to difficulties in diagnosis and treatment. Materials and methods: The review and analysis of scientific and medical literature based on the Scopus, Web of Science, MedLine, PubMed, NCBI databases, the study of which does not exceed 5 years, including literature reviews and the results of clinical trials. Results: Changes in the oral mucosa can be clearly specific. Clinicians can make the correct diagnosis and determine the tactics of treatment by appearance. However, in most cases the diagnosis of diseases with this anatomical location is complicated, because the clinical picture is nonspecific and often burdened with additional local and general adverse factors. A detailed clinical examination and additional research methods are required to establish the correct diagnosis. Diagnosis of oral mucosa diseases is based on a careful assessment of clinical and laboratory data. Conclusions: Taking into account the prevalence of diseases of the oral mucosa, of particular interest is the question of the course of the process of differentiation of the epithelium of various anatomical zones in the norm and the mechanisms of restructuring of the cellular composition in pathological processes, with the cops of objectifying the diagnosis, predicting the course of the disease and pathogenetically substantiated treatment.

The aim: Determination of the factors complications occurrence in prosthetics with metal-ceramic prostheses. Materials andmethods: Clinical, cytological, cytochemical methods and methods of statistical processing of the received data are applied. Results: A number of factors with different degrees of significance have been identified, which in the dynamics of clinical observations of the percentage of absorbed dispersion are decisive in the development of changes in the gums. At the stage of odontopreparation – the 1 factor, with the percentage of absorbed dispersion (12,3%) – preparation. The 2 factor – (11,9%) – traumatic. The 3 factor, periodontal, was slightly less significant (9,8%). In the dynamics of clinical observations for 45 days in the first place was the dissecting factor – (14%). The second most important factor was the vitality of the teeth – (11,5%). The 3 factor remained relatively stable – periodontal (8,5%). In the dynamics of clinical observations after 1 year, a redistribution of significance was noted. The largest percentage of absorbed dispersion covered periodontal factor – (15%). Vitality factor – (11%). Slightly lower, but clinically significant, of (8%) absorbed dispersion, was the preparation factor. Conclusions: Statistical analysis of the studied parameters made it possible to determine the key factors for predicting their development and diagnostics, it is important for organizing an increase in the effectiveness of orthopedic prophylactic therapeutic measures at the stages of restoration of dental hard tissues.
