Study of force loss of orthodontic elastomeric chains in the laboratory
Objective: to assess force degradation over time of four commercially available orthodontic elastomeric chains (Ormco, Dentaurum, 3M Unitek and G & H). Methods: The synthetic elastics were submerged in 37 °C synthetic saliva and stretched on the instrument at a distance of 30 mm. With a dynamometer, the delivered force was evaluated at different intervals: at baseline, after 1 hour, 1 day, 4 days 7 days, 14 days, 21 days and 28 days. The results were subjected to ANOVA and Tukeyâs test. The results showed that the elastomeric chains âOrmcoâ develop the least loss of power in all time tests (to 31.5% after 7 days, up to 35.1% after 28 days). At the same time, the elastomeric âDentaurumâ chain showed the highest percentage of strength loss (47.14% after 7 days, 58.57% after 28 days). No statically significant difference was found in force loss between«3M Unitek» and «G & H» elastomeric chains
Nonsurgical correction of skeletal class 2 malocclusion with Carriere Motion appliance

Overall, the Carriere Distalizer appears to be effective in early results in the treatment of Class II malocclusion
Studying of interrelation of quality of potable water in the zone of residing of children with noncariouses defeats of enamel of the teeth
The ecological trouble of water, influencing on the infringement of the mineralization of enamel, is able to serve as a factor of the stomatologic disease. Enamel hypoplasia is connected with mineralization infringement during the certain age period under the influence of the local and general pathological factors leading to infringement of formation of an enamel matrix, its mineralization and maturing
THE EFFECT OF ENVIRONMENTAL FACTORS ON ELASTOMERIC CHAINS AND NICKEL TITANIUM COIL SPRINGS
It is well known that elastomers exhibit viscoelasticity and as such have their mechanical properties modified by temperature. Nickel titanium archwires are also affected by temperature and have been modified with specific temperature related properties for clinical use. What is less well known is the effect that other environmental factors, such as food, might have on the force delivery properties of both elastomeric materials and nickel titanium coil springs used for space closure. The aim of this work was to determine the effect three common environmental factors coca cola, refined sunflower oil, and pasteurized milk have on elastomeric chain and nickel titanium coil springs. In addition, it was decided to re-examine the effect of temperature at 22 C, 36,6 C, and 55 C on both these space closing materials. Degradation force measurements were made at the following intervals: 0, 1, 7, 14, 21, and 28 days. The results indicated that elastomeric chains were affected by all the test food liquids while nickel titanium springs were more affected by low temperature
Intensity of development of somatic diseases of children's population in Kizlyar and Khasavyurt and cancer incidence
Aim. Study of the development of somatic and oncological diseases and the state of the dentoalveolar system as an indicator of somatic health on the example of the city of Kizlyar (a city of ecological trouble) and the city of Khasavyurt (ecological well-being).Materials and methods. To determine the health status of children and their mothers, a survey was conducted of 1015 children and (or) their parents (three age groups of the study), of which 528 were girls and 487 were boys, and for comparison, 542 children aged 2-17 years in the city of Khasavyurt (ecological well-being) northern zone of Dagestan. Patient selection criteria: 1) identical area of residence (Kizlyar, Khasavyurt); 2) children of preschool age from 2-6 years (1, 2, 3 health groups in the absence of somatic diseases in sub- and decompensated forms), 4 health groups with chronic somatic diseases and congenital malformations; 3) Children at the age of the period of changeable occlusion from 7 to 13 years old, 1-4 health groups; 4) Children aged 14 to 17 years of permanent occlusion, 1-4 health groups.Results. According to a study of schoolchildren aged 7 to 17 years in the city of Kizlyar, 47.1% of children with habitual mouth breathing or mixed breathing. Infantile type of swallowing in children was found in 23.8% of cases. Violation of posture in children was observed in 29% of cases, while in children from the city of Khasavyurt, this type of violation was observed only in 10.5% of cases. The main localizations of malignant neoplasms in the male population are the respiratory organs, stomach, skin, bladder, lip; in the structure of oncological morbidity in the female population, the largest number of patients with neoplasms of the mammary gland, skin, lymphatic and hematopoietic tissue, cervix, and stomach.In the population (period of permanent occlusion), there was a significant decrease in tumors from 0.8% to 0.4% out of 1000 examined, the endocrine system from 0.5% to 0.4%, blood diseases from 0.2% to 0.1%.Conclusions. The results obtained confirm the presence and development of somatic and oncological diseases from unfavorable factors in the region of residence. All indicators for the city of Khasavyurt (ecological well-being) 2 times lower than the data of the city of Kizlyar (city of ecological trouble)
Factors of congenital malformations of dentoalveolar anomalies in the children's population of Kizlyar (environment of trouble) and Khasavyurt (environment of well-being)
Analysis to identify the relationship between the unfavorable living environment and congenital malformations of dental anomalies in the children's population of Kizlyar (the environment of disadvantage) and Khasavyurt (the environment of well-being).Materials and methods. To identify the main causes of the appearance of congenital clefts, we conducted a survey of 125 parents of children with questions included in the questionnaire: Full name, gender, date of birth, address, nationality, what is the pregnancy, whether the mother took medication in the first 3 months of pregnancy, the level of hemoglobin and infectious diseases during pregnancy, whether there were cases (heredity).Results. Dates from 125 medical histories for 2017-2019 with different types of congenital cleft lip and palate showed that in 59 children, the chemical factor was the cause of the disease, since one of the parents worked in agriculture or an industrial enterprise with a chemical bias, for genetic reasons, 15 children; viral colds-22 children, anemia of pregnant women-25 cases. 35 patients with the chemical factor were born in Kizlyar, only 5 patients from Khasavyurt. Conclusions. The high level of morbidity of the child population in Kizlyar indicates the need to develop and implement recommendations for the organization of preventive and medical-dental care for adolescents and children from an early age

Oral health of children living in an orphanage
The hygienic condition of an oral cavity, intensity and prevalence dental caries in children living in Asenevsky orphanage of the Kaluga region and without regular dental service is studied. 17 children aged from 4 until 18 years (9 boys and 8 girls) were examined. Obtained data revealed low level of oral hygiene, a high prevalence (94.1%) and intensity of dental caries (5,9%). Furthermore the analysis of stomatologic health of handicapped children of the Moscow children's boarding school â 28 for the disabled where the stomatologist works is carried out
