Imaging Studies

Tooth displacement can often be viewed radiologically. Lateral and axial extrusive displacements may reveal widened periodontal ligament spaces. Axial intrusion displacement may reveal a blurred periodontal ligament.^[12]

Obtain 4 films (maxillary anterior and 3 periapical films from various angles) to evaluate a dental fracture or displacement. In the emergency department, because such specialized films often are not available, use a limited facial series and a Panorex to evaluate maxillary and mandibular fractures, foreign bodies, and displacement. A Panorex can be used to assess mandibular fracture.

Use a periapical film to view foreign objects, such as tooth fragments, within lacerated soft tissue.

Illumination can be used to visually identify fractures within the tooth, if present.
