An Ellis Class II fracture involves which tissues?
Show answer and explanation
Correct answer: D. Enamel and dentin, without pulp exposure
- A. ❌ Root involvement without crown fracture is Ellis Class IV/V territory in the extended classification (necrosis, avulsion, root fracture).
- B. ❌ Enamel-only is Ellis Class I.
- C. ❌ Enamel + dentin + pulp exposure is Ellis Class III.
- D. ✅ CORRECT — Ellis Class II is a fracture through ENAMEL AND DENTIN with the pulp NOT exposed. Dentinal tubules are open, so the tooth is sensitive and there is a route for bacterial contamination — prompt dentin coverage (glass ionomer or bonded composite) is required.
Note: Ellis: I = enamel · II = enamel + dentin · III = pulp exposed · IV = non-vital tooth · V = avulsion · VI = root fracture.
