This study aims to explore the mechanical factors contributing to tooth fractures that helps reduce the risk of failure. Cracks typically propagate through enamel that has lower fracture toughness. As the crack progresses toward the dentin-enamel junction (DEJ), the material becomes more ductile and exhibits higher fracture toughness. Whether the crack is arrested or continues to propagate depends on factors such as tooth health, and age. The study concluded that isotropic models provide an adequate representation for simulating cracks in enamel. Therefore, Linear Elastic Fracture Mechanics (LEFM) was employed to assess the fracture toughness. The stress intensity factor (SIF) was calculated for different crack lengths, indicating that longer cracks result in higher stress intensities, thus reducing the number of cycles required for failure.
