Replantation of avulsed teeth. A review.

Time is a critical factor in successful replantation. The avulsed tooth is simply washed and replaced immediately. Where contamination with soil occurs anti-tetanus prophylaxis is given and some form of splinting is necessary for 3-4 weeks. Endodontic therapy is performed prior to replacement if there is a delay of more than two hours and where apex formation is complete it should be commenced within 10 days. Calcium hydroxide is useful as a root canal dressing and in controlling resorption. The value of immediate replacement and treatment should be publicised.
