Avulsion and replantation of a primary incisor tooth.

Avulsion of a primary tooth is a serious dental trauma, and the guidelines of the International Association of Dental Traumatology and textbooks in paediatric dentistry do not recommend replantation. Such management can result in severe damage to the supporting structures, and together with avulsion itself is commonly associated with developmental disturbances of the permanent tooth. We report the case of replantation in a 9-month-old child with a successful outcome, in a unique situation where conditions were optimal and careful long-term follow up was possible.
