Dental clinicians should understand and master the international guidelines for the management of TDI, including proper diagnosis, standardized treatments and regular follow-up, so as to obtain the favorable outcomes.牙外伤是一种常见的口腔疾病，是指在突然的外力作用下，牙体硬组织、牙髓和（或）牙周组织发生急性损伤的一类疾病。本文以国际牙外伤协会恒牙牙外伤诊疗指南（2012年版）和美国牙髓病医师协会牙外伤诊疗指南（2013年版）为指导，结合临床实际，就口腔医师应掌握的牙外伤诊治指南及进展进行阐述，包括正确诊断、合理的治疗计划、规范的治疗并定期随访，更好地提高临床疗效。.
