ABSTRACT
Microhardness of dental tissues was assessed. Hard tissue specimens from 65 teeth removed for medical indications were examined. The enamel microhardness is 30-40% decreased in caries, whereas dentine is virtually intact. Depulpation decreases the enamel microhardness by 23-26%, while the microhardness of dentine is changed negligibly (by 1-1.5%).

A new approach to the anatomical structure peculiarities description of the crown part of the tooth surface by the system of the parallel sections is suggested. It helps to make their graphic picture and analytical description producing a new anthropometric system of assessing normal and pathological conditions.
