Abstract
This case report describes a case of avulsed left maxillary central incisor tooth which was replanted in the dental office. The tooth was gently rinsed of any debris and placed in normal saline during the examination and preparation of the replantation socket. The tooth was replanted and functionally splinted. The following week the tooth was opened for pulp extirpation and placement of calcium hydroxide. Two weeks later, the root canal was filled with gutta-percha and zinc oxide eugenol sealer, and the access cavity was restored with a bonded composite restoration; the splint was removed. Two year clinical and radiological follow up of the case showed ankylosis and infraocclusion of the replanted toothUpdate Dent. Coll. j: 2015; 5 (1): 30-34
Highlights
Avulsion or exarticulation occurs when a traumatic injury totally displaces a tooth from the socket
According to the National Clinical Guideline of The Royal College of Surgeons, England, the incidence of traumatic avulsion of teeth has been reported as 0.5-16% of all traumatized teeth
The extent of injury sustained by the periodontal ligament and the pulp, and the subsequent healing of these tissues will depend on the extra-alveolar period i.e. the time remains out of its socket and the handling of the tooth. 3
Summary
Avulsion or exarticulation occurs when a traumatic injury totally displaces a tooth from the socket. Traumatic injuries are quite common. 3. Pathophysiology lies in the fact that extrusive forces impinging on the teeth, when severe enough, can cause a tooth to be displaced out of its socket. Pathophysiology lies in the fact that extrusive forces impinging on the teeth, when severe enough, can cause a tooth to be displaced out of its socket For this to happen, the periodontal ligament would have ruptured with remnants remaining on the cementum of the root of the tooth and the inner walls of the alveolar socket. Clinical and radiological follow up-good healing of the soft tissue surrounding the replanted tooth was evident. Patient was recalled after three months for clinical and radiological evaluation His maxillary right central incisor tooth was diagnosed as pulp necrosis and treated endodontically. At two year follow up, clinically replanted tooth was sound but radiograph showed marked resorption
