Abstract
Replantation has been a subject of interest for centuries, and innumerable case reports of replanted teeth have been published. For 200 years one of the main points of discussion has been whether the teeth should be replanted with or without the periodontal membrane which remains attached to the tooth after extraction. The vitality of the periodontal membrane is directly related to the rapidity of root resorption which is the main cause of tooth loss. The more current research has established that, if the time the tooth has been exposed to the extra-oral environm ent is minimal, the prognosis for the attached periodontal membrane is good. However, in most cases the extraoral exposure time for accidentally avulsed teeth is not minimal and precludes the survival of the ·periodontal membrane. In these instances other means should be investigated to improve the prognosis for these teeth.
This study was directed toward preventing or retarding the resorption of the roots of replanted teeth. Nuva-seal pit and fissure sealant was selected as an agent to provide a thin plastic coating on the root surface to prevent resorption of the tooth structure. Phosphoric acid (50%) was the other agent to be applied to the roots of the teeth to produce a more porous surface and thus facilitate the reattachment of the periodontal fibers projecting from the alveolar socket walls. Also a new splinting technique was employed using Nuva-seal to attach replanted teeth to the adjacent teeth at their interproximal contacts and reinforcing this splint with acrylic bonding GAC cement.
In general, it was hoped that this experiment would result in more information about the healing process of the periodontium and expand existing knowledge concerning the replantation of teeth.
