The biological aging of hard tissues of the human body, including bone, dentin and enamel, is of substantial importance to their fatigue and fracture behavior. Investigations performed in this area have shown that the process of aging generally involves changes to the mineral content, which impairs the mechanisms of toughening and causes an increase in fragility. A topic less frequently explored in this area is the spatial variation in biological aging of these tissues, and the contributing mechanisms. The differences between chronological and biological aging are seldom discussed, as well as the potential for accelerated aging to occur as a result of environmental and physical stimuli. This talk will review the aging of dentin and enamel of human teeth, including the changes in microstructure and their contributions to the fatigue and fracture behavior. Then the concept of accelerated aging and spatial variations in the aging process will be explored.
