A 12-year-old patient has an Ellis Class 3 fracture (involving enamel, dentin, AND PULP) with a NEGATIVE pulp test. The MOST appropriate treatment is:

Correct answer: B. Root canal treatment (pulp necrosis indicated by negative test → RCT)

• A. Pulp capping requires vital pulp tissue — a negative test indicates necrosis, making pulp capping ineffective.
• B. Correct. ELLIS CLASS 3: fracture involving PULP. A NEGATIVE pulp test (non-vital/necrotic pulp) in a 12-year-old with a Class 3 fracture indicates the pulp has necrotized. ROOT CANAL TREATMENT is required. If the apex is CLOSED (mature root), standard RCT. If the apex is OPEN (immature, younger patient), apexification or regenerative endodontics would be considered.
• C. Apexogenesis requires vital pulp in an immature tooth — not applicable to necrotic pulp.
• D. Enameloplasty is for Class 1 (enamel only) — not for Class 3 with pulp exposure.
