Tooth fracture is a major concern in the field of restorative dentistry. However, knowledge of the causes for tooth fracture has developed from contributions that are largely based within the field of mechanics. The present manuscript presents a technical review of advances in understanding the fracture of teeth and the fatigue and fracture behavior of their hard tissues (i.e., dentin and enamel). The importance of evaluating the fracture resistance of these materials, and the role of applied mechanics in developing this knowledge will be reviewed. In addition, the complex microstructures of tooth tissues, their roles in resisting tooth fracture, and the importance of hydration and aging on the fracture resistance of tooth tissues will be discussed. Studies in this area are essential for increasing the success of current treatments in dentistry, as well as in facilitating the development of novel bio-inspired restorative materials for the future.
牙齿折断是修复牙科领域的一个主要问题。然而，关于牙齿折断原因的认识是基于力学领域的大量贡献而发展起来的。本手稿对牙齿折断以及其硬组织（即牙本质和牙釉质）的疲劳和断裂行为的理解进展进行了技术综述。将回顾评估这些材料抗折性的重要性以及应用力学在发展这一知识方面的作用。此外，还将讨论牙齿组织的复杂微观结构、它们在抵抗牙齿折断中的作用以及水化和老化对牙齿组织抗折性的重要性。该领域的研究对于提高当前牙科治疗的成功率以及推动未来新型生物启发式修复材料的开发至关重要。
