Abstract:

Traumatic dental injuries are caused by a collision that can generate enough mechanical energy to produce the injury. Injuries involve the hard dental tissues， the pulp and the periodontal tissues. Crown fractures and luxations of permanent teeth occur most commonly in all dental injuries. Proper diagnosis， treatment planning and follow-up are important for improving a favorable outcome. The study highlighted Chinese dentists’ need for continuing education in order to improve current knowledge in emergency management of teeth injuries. The International Association of Dental Traumatology（IADT）Guidelines for management of fractures and luxations of permanent teeth represent the best current evidence based on literature search and professional opinion. Guidelines should assist dentists and other health care professionals in decision making in order to provide the best care effectively and efficiently.

摘要：

牙外伤是指在突然的机械外力作用下，牙体硬组织、牙髓或牙周组织发生急性损伤的一种疾病。牙外伤可单独破坏一种组织，也可使多种组织同时受累。恒牙冠折和牙齿脱位性损伤是所有牙外伤中最常见的类型。牙外伤所涉及的临床诊断和治疗技术以及牙外伤的研究范围与口腔医学的多个学科密切相关。所以，正确的诊断、合理的治疗计划、按时随诊观察非常重要，直接影响着牙外伤的预后效果。本文通过对国内口腔医生牙外伤认知水平和临床诊治能力的分析，阐述了牙外伤继续教育的必要性；详细介绍了国际牙外伤协会（IADT）向全世界推荐使用的牙外伤临床治疗指南，帮助医生更好地掌握牙外伤的正确诊断与规范治疗，以及了解未来国内外牙外伤的临床研究方向。
