| Description |
A fracture confined to the enamel with loss of tooth structure. |
| Visual signs |
Visible loss of enamel. No visible sign of exposed dentin. |
| Percussion test |
Not tender. If tenderness is observed evaluate the tooth for a possible luxation or root fracture injury. |
| Mobility test |
Normal mobility. |
| Sensibility pulp test |
Usually positive. The test may be negative initially indicating transient pulpal damage. Monitor pulpal response until a definitive pulpal diagnosis can be made.
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 enamel loss is visible. |
| Radiographs recommended |
Periapical, occlusal and eccentric exposures. They are recommended in order to rule out the possible presence of a root fracture or a luxation injury. |
