What is the eruption sequence for the mandibular permanent dentition?

The eruption sequence for the mandibular permanent dentition is characterized by the order in which the permanent teeth typically emerge. The correct sequence begins with the first molars and progresses through the incisors, canines, and then the premolars.

In this case, the sequence "61234578" can be broken down as follows:

• The numbers correspond to specific teeth:
  • 6: Mandibular first molar
  • 1: Mandibular central incisor
  • 2: Mandibular lateral incisor
  • 3: Mandibular canine
  • 4: Mandibular first premolar
  • 5: Mandibular second premolar
  • 7: Mandibular second molar
  • 8: Mandibular third molar

Eruption usually starts with the first molars, which are among the first permanent teeth to emerge around age 6. This is followed closely by the central incisors, lateral incisors, canines, and premolars, with the second molar erupting around age 12 and the third molar (wisdom tooth) typically coming in later, usually in late adolescence or early adulthood.
