Mandibular Eruption Sequence — NDEB AFK MCQ

Correct answer: B — First molar

The mandibular first permanent molar typically erupts first in the mandible (age 6-7), although in some individuals the mandibular central incisor erupts simultaneously or slightly before. The eruption sequence in the mandible is typically: 6 → 1 → 2 → 3 → 4 → 5 → 7 → 8 (first molar → central incisor → lateral incisor → canine → first premolar → second premolar → second molar → third molar). Note that in the mandible, the canine erupts BEFORE the premolars, unlike the maxilla.
