An update version of the International Association of Dental Traumatology (IADT) guidelines for the management of traumatic dental injuries has been released in June 2020 (http://www.dentaltraumaguide.org). In this current revision, IADT has put forward a "core outcome set" (COS) for the diagnosis and treatment of dental trauma both in children and adults. The COS was developed and underpinned by a systematic review of the outcomes in the literature of dental trauma treatment. An outcome that was relevant to all traumatic dental injuries (TDI) was identified as "generic outcome" and those related only to one or more particular TDI were then included as "injury-specific outcomes". The aims of the present article are to help the dental clinicians in learning the latest version of the guideline so that they may quickly and accurately grasp the essence of the updated content and to assist them to choose the optimized treatment plan after judging and evaluating the specific clinical circumstances so as to maximize the chance of a favorable outcome.
