title: Different treatment outcomes of two intruded permanent incisors--a case report.
abstract: Intrusive luxation involves the displacement of the tooth apically into the alveolar socket. This type of injury represents a very complex wound, involving disruption of the marginal gingival seal, alveolar bone, periodontal ligament fibers, cementum and the neuro-vascular supply to the pulp, which results in severely compromised healing and possible complications. The case presented is a report of a 60-year-old lady who fell and intruded her two maxillary central incisors. The healing outcomes of the two central incisors were markedly different from each other even though they sustained similar injuries.
