Traumatic tooth dislocations

Priv. Doz. Dr. Pohl
Traumatic tooth dislocations cause periodontal and pulpal damage. Depending on type and severity of injury, root development and - in avulsed teeth - extraoral storage the prognosis of healing and survival is very good to extremely poor.
Following trauma often communications between endodontium and periodontium are established via dentinal tubules which are opened at the periodontal aspect. Infections located in the endodontium cause periodontal complications, the retention of the injured teeth is threatened even in the short run. In cases with a high risk of pulp necrosis a prophylactic endodontic treatment is indicated which additionally should be performed immediately or early after trauma. In appropriate teeth an extraoral retrograde insertion of posts into the root canal is advantageous. Besides, the early instillation of Ledermix promises a positive effect. Damage in the periodontium impairs healing. Modern antiinflammatory, antiresorptive and regeneration supporting therapies seem to enhance the results. An immediate and more active treatment is demanded in severe cases, an observant and delaying behavior is discouraged.
