This article explores the biomechanical properties of dentin, focusing on intrinsic toughening mechanisms such as crack deflection, bridging, and microcracking, which act to diminish crack propagation. The composite-like structure of dentin, comprising mineralized collagen fibrils within a heterogeneous matrix, facilitates a balance between stiffness and flexibility, resisting multiple cyclic loads under complex intraoral environments. The impact of dentin dehydration, age-related changes, and the formation of sclerotic dentin on fracture resistance in dentine is discussed. A thorough understanding of toughening mechanisms in dentin is essential for optimizing clinical approaches aiming to ensure the durable success of dental treatment. Додано в НРАТ 2025-03-24 Закрити
