Correct answer: C. Maxillary first molar
- A. Mandibular first molar
- B. Mandibular second premolar
- C. Maxillary first molar
- D. Maxillary second premolar
Explanation
Most posterior teeth are broader mesiodistally on the buccal than on the lingual side, but the maxillary first molar is the exception because its lingual portion is particularly broad. Its prominent mesiolingual cusp contributes to this reversed outline.
