A patient addicted to methamphetamine has extensive caries and a Class IV crown fracture on a maxillary central incisor with NO pulp exposure. What is the BEST treatment?
Show answer and explanation
Correct answer: B. Composite resin restoration
For a non-pulp-involved Class IV fracture, composite resin is the most conservative and appropriate choice even in high-caries-risk patients.
- A. Extraction is not indicated when the tooth is restorable and the pulp is not involved.
- B. CORRECT. Composite resin is the most conservative treatment for a Class IV fracture without pulp involvement. It is reversible, immediate, and appropriate for the clinical situation regardless of caries risk.
- C. A full crown is overtreatment for a fracture without pulp involvement that can be restored with composite.
- D. A veneer requires significant tooth preparation and is not indicated for Class IV fractures — structural compromise makes it inappropriate.
