Sir, the clinical problem of diagnosing and managing traumatised teeth is threefold, in terms of prevalence, complexity and ambiguity.

In 2012, the International Association of Dental Traumatology (IADT) published guidelines for the management of traumatic dental injuries and we would like to bring some of the available resources to the attention of BDJ readers.1,2,3

The Dental Trauma Guide is a non-profit website developed in cooperation between the Copenhagen University Hospital and IADT.4

The website contains a useful Trauma Pathfinder, which allows clinicians to input the presenting features of a traumatic dental injury, such as stage of tooth maturity, type of injury, and extraoral time. The Pathfinder uses this information to advise the clinical management indicated and to estimate prognosis using interactive diagrams to support learning. Annual subscription of £25 is required in order to fully access the interactive learning tools.

Smartphone applications to aid in the management of dental trauma are available to download on Apple and Android, negating the need to digest the full content of the IADT guidelines in an emergency situation that may present with little or no warning.

ToothSOS, the official free app of IADT, provides information to both patients and professionals in the event of a traumatic dental injury. The app provides pictures to help patients recognise injuries and direct them to seek emergency treatment as required. For professionals, a copy of IADT guidelines is made readily accessible.

Dental Trauma is a free app designed to provide accessible first aid advice and is endorsed by IADT. It aims to help parents, teachers, sports coaches and others to make appropriate decisions if they witness or experience a traumatic dental injury.

InjuredTooth app is available to purchase for £5 and is targeted for use by dentists. A basic trauma pathfinder is included. Data protection regulations restrict the transfer of personal data outside the EEA, therefore the functionality of this app is currently limited within the UK.5

Facilitating access to evidence-based guidelines for the diagnosis and management of traumatic dental injuries may improve outcomes for affected children. Smartphone applications may have a useful application in this respect.
