Enamel-dentin-pulp fracture - diagnostic signs

Description A fracture involving enamel and dentin with loss of tooth structure and exposure of the pulp.
Visual signs Visible loss of enamel and dentin and exposed pulp tissue.
Percussion test Not tender. If tenderness is observed evaluate the tooth for luxation or root fracture injury.
Mobility test Normal mobility.
Sensibility test Usually positive. The test is important in assessing risk of future healing complications. A lack of response at the initial examination indicates an increased risk of later pulp necrosis.
Radiographic findings The loss of tooth substance is visible.
Radiographs recommended Periapical, occlusal and eccentric exposure. They are recommended in order to rule out displacement or the possible presence of a luxation or a root fracture.

Radiograph of lip or cheek lacerations to search for tooth fragments or foreign material.
