Abstract
The problem of studying the prevalence of dentofacial abnormalities in children in the Sverdlovsk region is relevant, as the data for different regions are differ, which is confirmed by the heterogeneity of indicators and statistics in the research. In 2022, an epidemiological study was conducted among the children's population of 4 cities of the Sverdlovsk region to study the prevalence of dentofacial abnormalities in the age groups 3–5, 6, 12 and 15 years, a total of 455 children were examined. Registration of dentofacial abnormalities was carried out in the author's card of dentofacial system disorders developed, using the classifications of MGMSU and ICD-10. Statistical processing of the data obtained was carried out in STATISTICA 13.3. The study revealed a high prevalence of dentofacial abnormalities in children in the Sverdlovsk region – 71.43% ± 2.12. With age, there is a tendency to increase the frequency of dentofacial abnormalities: in children 3–5 years of dentofacial abnormalities were in 34.85% ± 5.87 cases; in the group of 6-year-olds – in 70.18% ± 4.28; and in groups of 12-year-old and 15-year-old children – 81.38% ± 3.23 and 80.00%. It was revealed that the older the children are, the more likely they have severe malocclusion compared to children aged 3–5 and 6. The groups noted high rates of dentition deformities, the number of which also increases with age (decrease in the length of the upper dentition was detected in 36.26% ± 2.25, the lower dentition – in 47.47% ± 2.34 of cases; narrowing of the upper dentition – in 55.60 ± 2.33%, lower dentition – in 45.49% ± 2.33 of cases). Dentition deformities are associated with the development of teeth abnormalities, such as teeth retention (13.10% ± 2.80 and 9.23% ± 2.54 of cases in 12- and 15-year-old children, respectively), as well as mandibular displacement (displacement to the side was detected in 22.20% ± 1.95 of cases). Performed study is justification for the development and implementation of a regional program for the prevention of dental diseases in children of the Sverdlovsk region.
