Abstract

The rate of biological maturation may have a genetic nature, associated with a certain type of constitution (Nikityuk, 2000). Longitudinal study of 210 boys and 159 girls was conducted for 4 years (ages 3 to 6) and of 66 boys and 59 girls for 10 years (ages 7 to 17). Biological age of the examined subjects was estimated from 3 to 9 years with the somatic criterion (Philippine test), from 5 to 14 years with odontological criterion, and from 9 to 17 years by the development of secondary sexual characteristics. Somatotypes of all children were assessed according to the Shtefko-Ostrovsky method (1929) with the 4 selected types: asthenic (A), thoracic (T), muscle (M) and digestive (D). In the first childhood constitutional differences in biological maturity were expressed as trends likely due to insufficient differentiation of somatotypes at this stage. In the second childhood somatotypes significantly differ in the results of the Philippine test only at the age of 7 years, when children have positive and negative values. Complete replacement of milk teeth with the permanent ones occurs in girl of type D at 10 years, of type M – at 11 years, of types T and A – at 12 years. In boys constitutional differences in teeth replacement are more pronounced before 11 years, while at the final stage (up to 13 years) they develop more synchronously. Variations of the loss of primary teeth in the representatives of different somatotypes are stronger than in the eruption of the permanent dentition. Secondary sexual characteristics in girls are accelerated in the types as follows: A
