The research targeted 3,232 children, 49,7% boys and 50,3% girls, aged 4,5 to 17, living in Tashkent city. The initial and average timing of permanent teeth on the lower jaw was characterized by incisor type and on the upper jaw by molar type; the age of completion of teething on both jaws was characterized by molar type. In children of both sexes, the teething sequence did not differ in the initial and middle teething stages, except for the upper canines and lower second premolars, and gender differences were clearly visible when the permanent bite was completed in the sequence of lower canines, lower first premolars and upper second premolars. In children, the lower teeth were teething before the upper teeth except for the premolars. In terms of teething timing, the asymmetry between contralateral teeth ranged from 1 to 3 months, indicating left-handed teething in boys and right-handed teeth in girls. In the 15-year-old age group, children in Tashkent have a complete permanent bite formation.
