Item Клінічна оцінка ефективності девіталізуючих паст при лікуванні пульпіту(ФО-П Шпак В.Б., 2023) Лахтін, Юрій Володимирович; Лахтин, Юрий Владимирович; Lakhtin, Yurii VolodymyrovychПроведено ретроспективне вивчення результатів лікування хронічного фіброзного пульпіту. Хворим накладали миш'яквмісну пасту та пасту на основі параформальдегіду. Оцінювали мортальний ефект. Результати дослідження показали, що доцільно використовувати девіталізуючу пасту на основі параформальдегіду, так як вона є більш ефективною та має клінічні переваги над девіталізуючими миш’яквмісними пастами.Item The state of the optical density of the alveolar process of the jaws of rats in supraocclusive relationships of individual teeth in the age aspect(Aluna Publishing, 2021) Лахтін, Юрій Володимирович; Лахтин, Юрий Владимирович; Lakhtin, Yurii Volodymyrovych; Звягін, Сергій Миколайович; Звягин, Сергей Николаевич; Zviahin, Serhii Mykolaiovych; Карпець, Лідія Михайлівна; Карпец, Лидия Михайловна; Karpets, Lidiia MykhailivnaThe aim of the study was to conduct a comparative assessment of the optical density of bone tissue of the alveolar process of the jaws of rats in supraocclusive relationships of individual teeth in the age aspect. Materials and methods: The study was performed on 60 white laboratory rats. Rats were divided into control (30 individuals) and experimental (30 individuals) groups. According to the age of rats each group was divided into 3 subgroups (10 animals): young, mature and senile. In the experimental group, the state of supraocclusion was modeled by increasing the height of the lower right second molars placing a seal 1 mm high. Experimental animals were removed from the experiment on the 15th day through decapitation. The lower jaws were skeletonized, jaw blocks were sawn in the molar area. Bone mineral density was determined using optical densitometry. The statistical processing defined the average (M) and its error (m). The statistical significance of the difference in two independent groups was performed according to nonparametric criteria (Mann-Whitney U-test and W-Wilcoxon test). Statistical processing was conducted with the help of integrated package of statistical program AtteStat 12.0.5 for MS Excel. Differences at p≤ 0.05 were considered statistically significant. Results: Statistical discrepancy is present in rats of mature and senile age, as well as between the indicators of all rats of the control and experimental groups (≤0.05). No significant difference was observed in young rats, but the indicators of the experimental group were 3.82% worse than in the control group. In senile rats, the density of the alveolar process decreased by 26.6%, in adult rats by 17.5%. Conclusions: The presence of supraocclusive relationships of individual teeth causes a decrease in bone density of the alveolar process of the jaws in rats. The greatest loss of density among age groups in elderly rats.Item Application of saliva crystalloscopy methods in the diagnosis of malignant tumours of salivary glands and Sjögren disease(International Academy of Science and Higher Education, 2016) Москаленко, Павло Олександрович; Москаленко, Павел Александрович; Moskalenko, Pavlo Oleksandrovych; Лахтін, Юрій Володимирович; Лахтин, Юрий Владимирович; Lakhtin, Yurii Volodymyrovych; Levkov, A.A.; Сміянов, Юрій Владиславович; Смиянов, Юрий Владиславович; Smiianov, Yurii VladyslavovychA high informational content of saliva crystalloscopy in the diagnosis of salivary glands tumours was proven; typical symptoms of Sjögren disease and malignant tumours of the salivary glands were found on the ground of the analysis of the presented research method.
