A 5-year-old fell with a complicated crown fracture (pulp exposure) of a primary maxillary central incisor; the tooth is mobile and adjacent teeth are also slightly mobile. Most appropriate treatment?

Correct answer: C. Extraction

• A. Pulpotomy doesn't address the significant mobility/luxation injury.
• B. Pulpectomy is undermined by the mobility and questionable supporting bone.
• C. Correct. With pulp exposure PLUS mobility (likely alveolar/luxation injury) in a primary incisor, extraction is most appropriate (also protecting the developing successor).
• D. Monitoring leaves an exposed pulp and unstable tooth — inappropriate.

Note: The document's highlight was ambiguous; the best clinical answer given mobility + pulp exposure in a primary tooth is extraction.
