When assessing a fractured lingual cusp of a mandibular premolar, what should be evaluated FIRST?
Show answer and explanation
Correct answer: B. Restorability
Restorability must be assessed first before any other treatment planning step. Evaluating restorability determines whether the tooth can be restored at all — considering the extent of fracture, remaining tooth structure, margin location relative to bone crest (biologic width), and crown-to-root ratio. It is futile to assess pulp vitality or plan restoration if the tooth is ultimately non-restorable.
- A. ❌ Pulp vitality testing is important but comes after confirming the tooth can be restored — an unrestorable tooth needs extraction regardless of pulp status.
- B. ✅ CORRECT – Restorability must be evaluated first. If the tooth cannot be restored, no further treatment planning is required.
- C. ❌ Occlusal contacts are relevant for the final restoration but are not the first priority when assessing a fracture.
- D. ❌ Periodontal status is part of comprehensive assessment but is not the first step when a fracture is present.
