This post is an adaptation of the Enamel-dentin-pulp fracture article found in the Dental Trauma Guide
A fracture involving enamel and dentin with loss of tooth structure and exposure of the pulp.
Etiology
Diagnosis
- 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.
