The Aim: Of this study was the evaluation of the effect of the antioxidant gel on the oral mucosa and reduction of the time of adaptation to a removable denture in patients with partial adentia.

Material And Methods: The study comprised 105 patients aged 30-65 years divided into three groups: the main group of 45 patients, the comparison group of 35 patients, the control group of 25 patients. The main group was given a prophylactic gel with natural astaxanthin after the delivery of a removable prosthesis.

Objective: To study the physical and mechanical properties of the new basic light polymer material in clinical conditions in pediatric orthodontic patients.

Material And Methods: The strength properties of 113 basic orthodontic devices made of photopolymer material without reinforcement with a screw, vestibular arch, and clasps t (55 devices, 30 of them for the upper jaw, 25 for the lower jaw) and with quartz mesh reinforcement of the base (58 devices: 30 for the upper jaw, 28 for the lower jaw) were studied in 60 children aged 3 to 12 years in the periods of temporary and removable bite.

Results: In total, breakdowns of the base in devices without reinforcement were noted in 5.

The aim of the work was to study changes in the time range of heart rate variability (HRV) against the background of changes in the concentration of corticosterone in blood plasma in rats after surgical trauma to the nasal septum. Septoplasty was simulated in 30 mature male Wistar rats weighing 210-290 g. ECG was recorded with subsequent analysis of the time domain of HRV, as well as blood sampling to estimate changes in the concentration of corticosterone in the blood plasma was performed.

Objective: The objective of the study was to improve the strength properties polymer by modifying its basis with various materials.

Material And Methods: A polymer in the form of a pink-colored plasticine mass with veins was studied, a quartz mesh «Quartz splint mesh» manufactured by RTD (France) and two metal gold-plated wire mesh (0.1 mm and 0.
