[The microhardness of dental tissues as an index of their normal functional stability and in pathological states]. / Mikrotverdost' tkanei zuba kak pokazatel' ikh funktsional'noi ustoichivosti v norme i pri patologicheskikh sostoianiiakh.

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 description of the anatomical characteristics of the surfaces of human teeth]. / Novyi podkhod k opisaniiu anatomicheskikh osobennostei poverkhnostei zubov cheloveka.
