Twelve-year follow-up of a replanted incisor

A case report with a 12-yr follow-up of a replanted maxillary incisor is presented. A maxillary incisor, #8, with incomplete root formation was replanted without splinting following a 2-h sojourn in salt water. The pulp responded positively to the electric pulp tester for 2 yr. There was no response to the electric pulp tester 5 yr postoperatively. Although there was some external root resorption, the root appeared to have reached normal length. Two parallel vertical radiolucent slits were present in a trabeculated substance in the site normally occupied by the pulp. This case illustrates an example of revascularization and pulp obliteration. Interestingly, at the 12-yr follow-up, the replanted tooth, as well as tooth 7, showed blunted apices that occurred following orthodontic tooth movement.
