Vascular changes in replanted and autotransplanted apicoectomized mature teeth of dogs.
The purpose of the present investigation was to study whether international fracturing of the root tip at the time of replantation or autotransplantation of mature teeth might improve the revascularization capacity of the pulp. The vascular system in apicoectomized and nonapicoectomized replanted and autotransplanted mature dog teeth was studied 10, 30 and  120 days postoperatively by means of a barium sulfate injection medium combined with microradiography. Pulpal revascularization occurred during a 120-day period in eight out of nine apicoectomized teeth. The pulp of the nonapicoectomized teeth did not revascularize.
