Abstract
Object. Dentoalveolar anomalies contribute to the development of morphological and functional disorders in the temporomandibular joint, and also lead to changes in aesthetics, chewing functions and speech formation. This report presents the results of a study of the prevalence and structure of dentoalveolar anomalies in adolescents of the indigenous minorities population of the Khanty-Mansiysk Avtonomniy Okrug ― Ugra. Data on the epidemiology of dentoalveolar anomalies are necessary for planning regional measures for the prevention of dental anomalies and deformities in the study area.
 The goal ― is to study the prevalence and the structure of dentoalveolar anomalies among adolescents of the indigenous minorities population of the Khanty-Mansiysk Avtonomniy Okrug ― Ugra.
 Methodology. Expedition and exploration method carried out a comprehensive dental examination adolescents of indigenous minorities population in a number of areas of the Khanty-Mansiysk Avtonomniy Okrug ― Ugra. Evaluation of dental status was carried out according to the criteria of the World Health Organization. In the section “dento-alveolar anomalies”, the density of teeth and gaps, as well as the main types of malocclusion, were recorded. 
 Results. The prevalence of dentoalveolar anomalies among the surveyed was 35,4 %. The proportion of crowded teeth in the overall structure of the dental-alveolar anomalies is 30,3 %, the proportion of diastema is 2,1 %. The frequency of occlusion anomalies against the background of connective tissue dysplasia is 3,5 times higher.
 Summary. The high prevalence of dentoalveolar anomalies among adolescents of the indigenous minorities population of the Khanty-Mansiyskiy Avtonomniy Okrug ― Ugra was revealed. Most often, dental-alveolar anomalies were occured in the form of crowding of the upper and lower teeth, the gaps between the incisors and canines, the abnormal position of the incisors on the upper and lower jaw, changes in the closure of the molars. Dental-alveolar anomalies were more often recorded in the group of adolescents with signs of CTD.

Summary
The prevalence of dentoalveolar anomalies among the surveyed was 35,4 %. The proportion of crowded teeth in the overall structure of the dental-alveolar anomalies is 30,3 %, the proportion of diastema is 2,1 %. Dental-alveolar anomalies were occured in the form of crowding of the upper and lower teeth, the gaps between the incisors and canines, the abnormal position of the incisors on the upper and lower jaw, changes in the closure of the molars. При этом эпидемиологического исследования с оценкой уровней стоматологического здоровья, медицинской помощи при стоматологических заболеваниях, факторов риска их развития у коренного малочисленного населения в ХМАО ― Югре, позволяющего внести изменения и дополнения в программы профилактики, не проводилось [14, 15].
