Abstract:

Tooth fracture reduced mastication efficiency of patients, therefore, it is necessary to understand the crack propagation behavior of tooth. Studying the fracture toughness and fatigue crack growth behavior of enamel and dentin using fracture mechanics is also important for preventing various disease of tooth and developing materials for restorative dentistry. In this article, the fracture behaviors of dentin and enamel were reviewed.

Key words: enamel, dentin, fracture toughness, fatigue crack growth
