Study Notes
Maxillary First Molar
- The distolingual cusp of the maxillary first molar is of little practical use.
- The supplemental cusp can grade down to a series of grooves, depressions, or pits on the mesial portion of the lingual surface, a morphological trait known as "Carabelli trait".
- The maxillary first molar has 4-5 well-developed functioning cusps.
Maxillary Teeth
- The maxillary first molar is normally the largest tooth in the maxillary arch.
Maxillary Second Molar
- The root of the maxillary second molar typically completes its development at around 12-13 years of age.
- The enamel of the maxillary second molar completes its development at around 2-3 years after eruption.
- The eruption of the maxillary second molar typically occurs at around 12-13 years of age.
- The first evidence of calcification for the maxillary second molar occurs at around 2-3 years after birth.
