Measurement of the elastic modulus of dental pieces

Understanding the mechanical properties of human teeth is important to clinical tooth preparation and to the development of restorative materials. Particularly, the elastic modulus of materials used in restoration of dental parts subjected to endodontic treatment must be compatible with the original...
