It was investigated in anthropological aspect, the contemporary Bulgarian population from the regions of Kustendil, Sapareva banja, Alino and Batanovtsy. It were explored four groups by 100 persons of both sexes, 12-16 aged persons. A big number of basic odontological traits of race-diagnostic and taxonomic meaning were examined. The obtained data were processed and analyzed by Zubov's method (1968). As a whole, according to the percentage frequency of the odontological traits, the investigate a population can be related to the Western odontological stem. Some of the odontological traits, however, like the showel-shaped upper medial incisors show an increased frequency, that is an indication of a presence of 'eastern' admixture in the ethnogenesis of this population.
