Summary

The microhardness of the tooth enamel of human permanent premolars and canines differs in different parts of the crown. The microhardness of the enamel is lower in the sections of the predominantly straight-line orientation of enamel prisms. Such areas include the middle part of the crown of permanent premolars on its vestibular, lingual and lateral surfaces, the upper part of the lingual surface and the lower part of the lateral surfaces; the upper part of the crown of permanent canines on its vestibular and lingual surface. The microhardness of the enamel of deciduous canine tooth does not differ in different parts and surfaces of the crown.

Key words: enamel microhardness, premolar teeth, canine teeth
