Which tooth is the widest FL?

  1. Maxillary first molar

  2. Mandibular first molar

  3. Maxillary second molar

  4. Mandibular second molar

The correct answer is: Maxillary first molar

The maxillary first molar is the widest FL, as it has three large cusps and a wide buccal surface compared to the other molars. The mandibular first molar (option B) is narrower due to its two smaller buccal cusps. The maxillary second molar (option C) has a smaller mesiolingual cusp and a narrower buccal surface than the first molar. The mandibular second molar (option D) is also narrower due to its smaller mesiolingual cusp and smaller buccal cusps. Therefore, the only option that fits the criteria of being the widest FL is the maxillary first molar (option A).
