很少有人注意到牙髓治疗后修复的牙齿对断裂的抵抗力。本研究探讨上颌中切牙对模拟创伤的抗冲击能力。未经治疗的牙齿、经根管治疗的牙齿和使用平行不锈钢桩修复的牙齿受到相同的影响。记录各组的吸收能值与根管预备物的大小和桩径的变化进行比较。研究结果表明，保留牙齿内部结构和使用较小的根管桩可以最大限度地抵抗骨折。
Little attention has been given to the resistance to fracture of teeth that have been endodontically treated and subsequently restored. This study investigates the impact resistance of maxillary central incisors to simulated trauma. Untreated teeth, teeth treated endodontically, and teeth restored with the use of parallel stainless steel posts were subjected to identical impacts. The absorbed energy values recorded for each group were compared with changes in the size of the endodontic preparation and the post diameter. Results of the study show that preservation of internal tooth structure and the use of smaller posts in teeth that have been endodontically treated provide maximum resistance to fracture.
