||Displacement of the tooth into the alveolar bone. This injury is accompanied by comminution or fracture of the alveolar socket.
||The tooth is displaced axially into the alveolar bone.
||Usually gives a high metallic (ankylotic) sound.
||The tooth is immobile.
||Sensibility test will likely give negative response.
In immature, not fully developed teeth, pulpal revascularization may occur.
||The periodontal ligament space may be absent from all or part of the root. The cemento-enamel junction is located more apically in the intruded tooth than in adjacent non-injured teeth, at times even apical
to the marginal bone level.
||As a routine: Occlusal, periapical exposure and lateral view from the mesial or distal aspect of the tooth in question. If the tooth is totally intruded a lateral exposure is indicated to make sure the tooth has not penetrated the nasal cavity.
