A patient presents after trauma with a fracture involving the enamel and dentin of the crown, but the pulp is NOT exposed. How is this classified?
Show answer and explanation
Correct answer: A. Uncomplicated crown fracture
- A. An UNCOMPLICATED crown fracture involves fracture of enamel and/or dentin WITHOUT pulp exposure. The pulp remains protected by dentin, and treatment focuses on covering exposed dentin and monitoring pulp vitality. ✓
- B. A crown-root fracture extends below the gingival margin and involves the root structure — more complex than a simple crown fracture.
- C. A vertical root fracture runs longitudinally through the root — it is a different entity not visible clinically after trauma.
- D. A COMPLICATED crown fracture involves enamel, dentin, AND pulp exposure. This is classified as complicated because the pulp is at risk for infection.
