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.
