[Diagnosis and treatment planning of traumatic dental injury].

Traumatic dental injury (TDI), one of the common dental diseases, is defined as acute injuries to tooth hard tissues, dental pulp and/or periodontal tissues caused by sudden forces. Based on the Guidelines for the Management of TDI by International Association of Dental Traumatology (2012) and the Recommended Guidelines of the American Association of Endodontists for the Treatment of TDI (2013) for the permanent teeth, and combined with the authors' clinical experiences, the contemporary classification and clinical perspective of TDI were introduced in detail. 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.
