Which tooth has the most distinct MF cervical ridge and transverse ridge?

  1. Primary mandibular first molar

  2. Primary mandibular second molar

  3. Mandibular first molar

  4. Maxillary first molar

The correct answer is: Primary mandibular first molar

The primary mandibular first and second molars both have well-developed mesial and distal cervical ridges, while the mandibular first molar has a prominent transverse ridge which is most distinct on the MF surface. The maxillary first molar does not have as prominent of a transverse ridge as the MF cervical ridge, making it an incorrect choice. Additionally, the mandibular second molar does not have as prominent of a transverse ridge as the first molar, making it an incorrect choice as well.
