Dental treatment of children under general anesthesia during the period of matrial law.

OBJECTIVE: Aim: To summarize the experience of providing dental medical care under general anesthesia to children from different regions of Ukraine during the martial law, taking into account the factors affecting the choice of optimal conditions for dental treatment. PATIENTS AND METHODS: Materials and Methods: Dental treatment under general anesthesia of 1,258 children from different regions of Ukraine has been performed since March 2022. The condition of the teeth (df, df+DMF, DMF) and hygienic state of the oral cavity (OHI-S) were determined. The level of awareness of parents regarding the preservation of children's dental health was studied through a questionnaire. RESULTS: Results: An unsatisfactory oral hygiene, a high level of caries were found in the vast majority of children. The highest df was observed in the group of children aged 3 to 6 years (7.14±0.33), which is significantly higher than in the group of children under 3 years of age (4.32±1.04, p≤0.05). The worst oral hygiene was observed in children aged 6-12 years (OHI-S 2.62±0.32). An insufficient level of awareness of parents and children regarding dental health was revealed. A total of 1,712 operations under general anesthesia were performed. The majority of patients could not regularly appear for follow-up examinations due to the forced departure from the country. CONCLUSION: Conclusions: The organization of dental treatment under general anesthesia allows solving a number of problems of dental care for children during the war.

PROFESSIONAL TRAINING OF MASTERS OF DENTISTRY WITHIN QUARANTINE RESTRICTIONS AND MARTIAL LAW: A COMPARATIVE ANALYSIS OF EDUCATIONAL PROCESS.

OBJECTIVE: The aim: To present a comparative analysis of the educational technologies effectiveness that were used in the process of professional training of masters of dentistry during quarantine restrictions and martial law. PATIENTS AND METHODS: Materials and methods: To perform the set tasks, the following the empirical methods of scientific research were used: quantitative data were collected based on analyzing the results of students' educational achievements, as well as implementing special questionnaire that was sent to the students of the Faculty of Dentistry of NMU; qualitative data were collected with the help of several focus groups formed from students and teachers of the faculty. Analysis was undertaken using statistical methods (Pearson's test), and qualitative data were analyzed descriptively. RESULTS: Results: This paper analyzes the effectiveness of educational technologies used during quarantine restrictions and martial law, the role of phantom classes in providing professional training of dentistry specialists, summarizes the results of a comprehensive analysis of scientific literature, teaching experience at the dental faculty and the results of sociological research (student surveys, discussion in focus groups). CONCLUSION: Conclusions: The outbreak of the COVID-19 pandemic and the full-scale war unleashed by the russian federation in Ukraine forced to quickly find and implement mixed forms of teaching future masters of dentistry, which, in combination with digital technologies, enables implementing high-quality and effective training.

The effect of hyaluronic acid on the periodontium in spontaneous periodontitis in rats / El efecto del ácido hialurónico sobre el periodonto en periodontitis espontánea en ratas

SUMMARY: The aim of the article was to study changes in periodontal tissues in rats with spontaneous periodontitis (SP) and to evaluate the effect of hyaluronic acid (HA) on the state of the periodontium. Wistar rats with signs of SP were divided into 6 groups: 1) intact group; 2) intact animals with HA "HD-1,0 MDa"; 3) SP group; 4) SP with HA "S-2,4 MDa"; 5) SP with HA "ST-2,4 MDa"; 6) SP with HA "HD-1,0 MDa". The study of the periodontium rats with SP noted the main structural changes (collagen reduction, resorption of alveolar bone, dilatation and stasis of the vessels of the periodontium, gingival papilla and tooth pulp), which were assessed as moderate. Morphological evidence of inflammation was infiltration of neutrophils into the connective tissue of the gums, without the formation of abscesses. Local administration of HA did not cause additional structural damage in periodontal tissues of rats with SP, but also did not affect changes in the microvascular system of periodontium and tooth pulp, periodontal ligaments, only a tendency to inhibit alveolar bone resorption in rats was noted. One can consider the tendency to improve the condition of periodontal tissues in the group of rats injected with high molecular HA and HA with mannitol (2.4 MDa).

RESUMEN: El objetivo del artículo fue estudiar los cambios en los tejidos periodontales en ratas con periodontitis espontánea (PE) y evaluar el efecto del ácido hialurónico (HA) sobre el estado del periodonto. Las ratas Wistar con signos de PE se dividieron en 6 grupos: 1) grupo intacto; 2) animales intactos con HA "HD-1,0 MDa"; 3) grupo PE; 4) PE con HA "S-2,4 MDa"; 5) PE con HA "ST-2,4 MDa"; 6) PE con HA "HD-1,0 MDa". En las ratas con PS se observaron los principales cambios estructurales (reducción de colágeno, reabsorción del hueso alveolar, dilatación y estasis de los vasos del periodonto, papila gingival y pulpa dentaria), que fueron evaluados como moderados. La evidencia morfológica de inflamación fue la infiltración de neutrófilos en el tejido conectivo de las encías, sin la formación de abscesos. La administración local de HA no causó daño estructural adicional en los tejidos periodontales de las ratas con PE, pero tampoco se produjo cambios en el sistema microvascular del periodonto y en la pulpa dental y ligamentos periodontales.Se observó una tendencia a inhibir la resorción del hueso alveolar. Se puede considerar la tendencia a mejorar el estado de los tejidos periodontales en el grupo de ratas inyectadas con HA de alto peso molecular y HA con manitol (2,4 MDa).
