<p>Traumatic Dental Injuries – Avulsions<br>LT Allen D. Rasmussen, DC, USN and CAPT Terry D. Webb, DC, USN<br><br>Introduction<br>Avulsion of permanent teeth accounts for 0.5 – 3% of dental trauma and most frequently occurs among 7 – 9 year old children. Avulsions are more common due to the decreased mineral content in bone and still ma-turing periodontal ligament among newly erupted teeth.<br><br>The included chart titled Treatment Guidelines for Avulsed Permanent Teeth reviews step by step protocols by the International Association of Dental Traumatology and the American Association of Endodontists. Protocols are established based on root developmental status (open apex or closed apex) and tooth status at time of presentation to the dentist (already replanted, dry time less than 60 min, dry time greater than 60 min). Additional information and clarification for the protocols are given below.<br><br>The purpose of this Clinical Update is to review the treatment guide-lines and recent updates in managing avulsions from the International Association of Dental Traumatology (IADT) guidelines for the management of traumatic dental injuries: 2. Avulsion of permanent teeth and The recommended Guidelines of the American Association of Endodon-tists (AAE) for the Treatment of Traumatic Dental Injuries.
