Effect of ageing and endodontic treatment on the thermal stability of human dentin.

Background: Human dentin is a highly calcified tissue of mesenchymal origin with a heterogeneous structure. Its morphology is constantly remodelled throughout the life span of the tooth, as well as under the influence of external stimuli.

Objective: The aim of the present study was to obtain information about the thermal changes in the crown and root dentin specimens of vital and devitalized teeth.
