Abstract

The study of occurrence of main dentoalveolar anomalies among young men residing in St. Petersburg and Leningrad region is based on dental inspection of 2,854 males aged from 17 to 21 years. It is established that 72.2% of the teenagers examined suffer from various dentoalveolar anomalies including distal occlusion - 20.5%, mesial occlusion - 10.2%, overbite - 16.2%, crossbite - 5.3%, open bite - 7.3%. Misplacement and teeth crowding (7.3%) as well as diastema (5.4%) were noted as the most often dentoalveolar anomalies among young men. Among young men residing in St. Petersburg 55.4% examined teenagers underwent orthodontic treatmen, with 59.7% - in municipal health clinics, and 40.3% - in private dental clinics and surgeries. Among residents of Leningrad region orthodontic treatment was received by 44.6% of young men; 22.5% of them- in municipal clinics, and 77.5% - in private dental surgeries. There are some difficulties in providing orthodontic treatment to persons living in suburbs of the megalopolis.
