In normal occlusion , with which grooves / surface of the permanent mandibular first molar does the mesiobuccal cusp of the permanent maxillary first molar occlude______________?

Correct answer: A. Mesiobuccal surface

  • A. Mesiobuccal surface
  • B. Mesial surface
  • C. Distobuccal groove
  • D. Transverse groove

Explanation

The mesiobuccal cusp of the maxillary first molar normally fits into the buccal groove region of the mandibular first molar, establishing the Class I molar relationship. Among the listed choices, the mesiobuccal surface is the intended description, although “buccal groove” would be more anatomically precise.
