Документ Assessment of indicators of bone tissue resorption in patients with chronic generalized periodontitis according to the data of cone-beam computer tomography(Тернопільський національний медичний університет, 2023-02-01) Hasiuk, P. A.; Korobeinikova, Yu. L.; Piasetska, L. V.; Korobeinikov, L. S.; Demkovych, A. Ye.; Kalashnikov, D. V.; Zubchenkо, S. G.; Гасюк, Петро Анатолійович; Коробейнікова, Юлія Леонідівна; Коробейніков, Леонід Сергійович; Калашніков, Дмитро Вікторович; Зубченко, Сергій ГригоровичSummary. One of the criteria for assessing the degree of pathological changes in periodontal tissues is resorption of the bone tissue of the alveolar process of the jaw. However, changes from the vestibular and oral surfaces on a panorama or focused intraoral x-rays are covered by the shadow of the teeth and objectively do not provide an opportunity for accurate diagnosis of pathological changes in periodontal tissues. The only technique that makes it possible to obtain a three-dimensional image of the studied area with minimal exposure is cone-beam computed tomography (CBCT). The aim of this study – to evaluate bone tissue resorption in the area of frontal teeth of patients with chronic generalized periodontitis according to CBCT data. Materials and Methods. The study analyzed the resorption of bone tissue in the area of frontal teeth (80 teeth) in patients with chronic generalized periodontitis. The average age of the subjects was 34–44 years. The EzD2009 software and the basic interface to work in the main MPR (multiplenar reformation) option – multiplenar visualization of a threeplane image was used for CBCT analysis, with adjustment of the thickness of the selected layer (TH) from 0.03 mm to 3.0 cm. Results and Discussion. The results of cone-beam computed tomography revealed a significant difference in the bone resorption rates of the alveolar process of the jaw from the medial, distal, and vestibulo-oral sides. Conclusions. This indicates that a detailed study of this indicator is an essential factor in the diagnosis of periodontal changes in patients with chronic generalized periodontitis.Документ Аnalysis of the influence of basic acrylic plastics "Ftoraks" and "Villacryl H Plus" on the main hematological parameters in the experiment(Тернопільський національний медичний університет імені І. Я. Горбачевського, 2023-05) Rosolovska, S. O.; Kindiy, D. D.; Hasiuk, P. A.; Kindiy, V. D.; Vorobets, A. B.; Demkovych, A. Ye.; Kindiy, P. D.; Росоловська, Світлана Олексіївна; Кіндій, Дмитро Данилович; Гасюк, Петро Анатолійович; Кіндій, Віктор Данилович; Воробець, Анна Богданівна; Демкович, Андрій Євгенович; Кіндій, Павло ДмитровичThe effectiveness of orthopedic treatment significantly depends on the properties of the basic plastics used in the manufacture of dentures. The aim of the study – to study the effect of acrylic plastics "Ftoraks" and "Villacryl H Plus", the polymerization of which was carried out by different methods, on the main hematological parameters. Materials and Methods. The study and comparative characterization of the possible toxic effects of dental base acrylic plastics "Ftoraks" and "Villacryl H Plus", which were polymerized by different methods, on the main hematological parameters were performed on white outbred rats, which implanted samples of these materials in periodontal tissue. Results and Discussion. As a result of the study, it was found that animals implanted with samples of the above acrylic plastics polymerized in a "water bath" methodic in the blood had a decrease of hemoglobin, leukocytosis, increased number of band and segment nuclear neutrophils, increase in the number of eosinophils and decrease of basophils in comparison with the control and other groups of animals. In the study of samples polymerized in the apparatus for dry polymerization under pressure and in the apparatus for molding plastics, it was found that fluctuations in the content of the main hematological parameters are within the physiological norm and do not differ significantly from the control. Сonclusions. Dental basic acrylic plastics "Ftoraks" and "Villacryl H Plus" polymerization of which was carried out by the method of dry polymerization with pressure and in the apparatus for foundry pressing of plastics cause less toxic effects on hematological parameters of the blood.
