Abstract

The crack propagation in the proximity of the dentin-enamel junction (DEJ), was studied using interfacial fracture mechanics. The DEJ in teeth represents the zone between two distinct calcified tissues with biomechanical properties, enamel and dentin. To evaluate the toughness of the DEJ, a series of Vickers microhardness indents is placed in polished sections of 13 non-carious extracted human molars. It is found that the DEJ has a hierarchical microstructure with a three-dimensional (3D) scalloped appearance along the interface.
