Aging and the related changes in mechanical behavior of hard tissues of the human body are becoming increasingly important. In this study the influence of aging on the mechanical behavior of human enamel was evaluated using 3rd molars from young (18 ≤ age ≤ 30 years) and old (55 ≤ age) patients. The hardness and elastic modulus were quantified using nanoindentation as a function of distance from the Dentin–Enamel Junction (DEJ) and within three different regions of the crown (i.e. cervical…

Mechanical Properties of Enamel Nanocomposite
TLDR
The predicted value of the toughness of the protein present in the nanocomposite was comparable to that of other bioproteins reported in the literature and the work of fracture estimated from the measured value of Toughness agreed well with the experimental data reported inThe literature.
VARIATIONS IN THE MECHANICAL, CHEMICAL, AND MICROSTRUCTURAL PROPERTIES OF ENAMEL
Teeth are important in the survival of humans and animals and have functions in mastication, esthetics, speech, and protection. Teeth are composed of a hard outer covering of enamel, a mid-layer of

The role of property gradients on the mechanical behavior of human enamel.
On the brittleness of enamel and selected dental materials
TLDR
The brittleness index could serve as a useful scale in the design of materials used for crown replacement, as well as a quantitative tool for characterizing degradation in the mechanical behavior of enamel.
Variation in mechanical and structural properties of enamel in primate molars
TLDR
Overall structural and mechanical patterns were similar in the primate species studied despite substantial differences in diet, suggesting these properties are potentially evolutionary conserved.

TLDR
This study investigated the dependence of the hardness and elastic modulus of human enamel on the indent depth and attributed the depth dependence to the continuous microstructure evolution induced by the nanoindenter tip.
Indentation Damage and Mechanical Properties of Human Enamel and Dentin
TLDR
In indentation studies to understand the microfracture and deformation and the microcrackmicrostructure interactions of teeth, it is concluded that the cracks strongly interact with the DEJ and the enamel rods, and that the mechanical properties of teeth are functions of microstructural orientations.
