| 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. |
