牙外伤造成牙体硬组织和牙周组织的损伤,可能会引起牙髓暴露、感染或影响牙髓组织的血液供应,继而对牙髓组织的预后造成影响。本文通过分类阐述恒牙外伤的牙髓组织预后和牙髓治疗方案,为临床及时准确判断外伤牙的牙髓状态、合理选择牙髓保存和治疗技术、提高恒牙外伤的远期疗效提供参考。
Dental trauma causes damage to the hard and periodontal tissues of the tooth and may cause pulp exposure, infection or blood supply to the pulp tissue, which in turn affects the prognosis of pulp tissue. In this paper, we classify the prognosis and endodontic treatment of pulp of permanent tooth trauma, and provide a reference for clinical judgment of endodontic status of traumatic teeth in time, reasonable choice of pulp preservation and treatment techniques and improvement of long-term efficacy of permanent tooth trauma.
