“…It should have a root canal filling placed immediately, be kept moist while outside the mouth, be stabilized after insertion in the tooth socket and be protected from occlusion. The severed periodontal fibers must be left intact on the root surface [28], Calcium aluminate has proved to be a good nontoxic ceramic implant material for root replacement and alveolar ridge augmentation [27]. Pyrolite carbon has produced excellent clinical results as a blade vent type replacement material or a two-stage root/crown cone-shaped artificial tooth implant [25].…”

“…But not all dentin resorption is followed by cementogenesis. For example, a recent reimplantation study in baboons 44 noted that tooth surfaces, at which cementum had been disked away immediately prior to reimplantation, showed resorp tion of the dentin wall. Root surfaces at which cemen tum and severed but still attached, fibers were left intact demonstrated reformation of a functioning perio dontal membrane.…”

“…Dentoalveolar ankylosis has therefore also been called replacement resorption (1,2). Ankylosis occurs when an avulsed tooth is replanted after prolonged extraoral dry storage (3)(4)(5)(6)(7)(8)(9), or after storage in an unsuitable medium (10)(11)(12). Partial or complete removal of the periodontal membrane prior to replantation has also resulted in ankylosis (3,7,(13)(14)(15).…”

The mechanism behind the develop-ment of ankylosis is not known, but clinical experience and experimental studies indicate that the vitality of the periodontal membrane is of critical importance in preventing ankylosis (3,11,12,16,17).…”

The present experimental studies in monkeys were undertaken to study the initiation and progression of dentoalveolar ankylosis of replanted teeth and associated root resorption. Maxillary and mandibular lateral incisors were extracted and replanted after an extraoral period of 15 min or 1 h. Teeth with an extraoral period of 1 h were endodontically treated. Half the number of monkeys were given antibiotics at the time of replantation. The observation periods varied from 2 days to 40 weeks. Irrespective of the length of the extraoral period, initial root resorption and minor areas of ankylosis were found 1 week after replantation. The initial ankylosis was not preceded by root resorption. In teeth replanted after an extraoral period of 15 min the ankylotic area did not increase with increasing time after replantation. Instead the periodontal membrane was re-established, separating the root surface from the alveolar bone. In teeth replanted after an extraoral period of 1 h, the initial ankylotic area increased with increasing time after replantation. Eight weeks and more after replantation, most of the periodontal membrane was replaced by bone covered by osteoblasts and occasional osteoblasts that were in continuity with the endosteal cells outlining the marrow spaces of the alveolar bone. The cementum and dentin were then gradually resorbed with increasing time after replantation. Antibiotics given at the time of replantation reduced the initial inflammation in the periodontal membrane and the inflammatory root resorption after all observation periods and it also seemed to some extent to prevent bacteria from entering the necrotic pulp tissue. Based on the present results it is suggested that root resorption associated with dentoalveolar ankylosis is initiated by endosteal osteoblasts and is thus a hormonally regulated process. This is in contrast to inflammatory root resorption, which seems to be triggered by inflammatory cells.
