  16. what are distinguishing features of MAX LATERALS? (2)
    • crown has greatest degree of variation in form EXCEPT 3rds.
    • congenitally missing
  17. the mandibular CENTRALS distinguishing features are: (2)
    • MOST symmetrical
    • SMALLER than laterals
  18. the mandibular LATERAL distinguishing features are:
    • slightly LARGER than centrals
    • crown appears DISTALLY oriented
  19. which teeth are the smoothest because they have no cingulum and are the smallest?
    mandibular incisors
  20. what other teeth do the mandibular canines resemble from the lingual aspect?
    mandibular laterals
  21. from the facial, mandibular canines most resemble:
    maxillary canines
  22. on incisors, the mesial marginal ridge is more_____ and the distal marginal ridge is more_______
    • distinct
    • rounded
  23. what are the functions of premolars? (2)
    tearing and grinding (oh baby!)
  24. the first mandibular premolar resembles:
    a canine
  25. a bifurcated root is found on which premolars?
    max 1st premolars!
  26. which premolar has a non-functional lingual cusp but functional buccal cusp?
    mandibular 1st premolar
  27. what are the succedaneous teeth that replace the primary 1st and 2nd molars?
    1st and 2nd premolars! Yay! this if fun!
  28. R/L distinguishing features of which premolar are:
    mesially displaced lingual cusp
    mesial concavity
    mesial cusp slope longer than distal cusp slope on buccal cusp
    Max 1st premolar
  29. R/L distinctions of which premolar are:
    lingual cusp displaced toward mesial?
    Max 2nd premolars
  30. R/L distinctions of which premolar are:
    mesial cusp slope shorter than distal
    distal margin more rounded
    man 1st premolar (that one was easy! not!)
  31. R/L distinctions of which premolar are:
    2 cusps: lingual cusp shifts mesially
    3 cusps: ML cusp larger
    ROOT: proximal root concavities
    dead give away, it is the man 2nd premolar!
  32. which tooth can have the cusp of carabelli?
    the MAX 1st Molar!
  33. which lingual root is the largest and longest?
    max 1st molars
  34. T/F all MAX MOLARS can account for sinusitis?
  35. which occlusal table has the cross-shaped groove pattern?
    MAN 2nd molars!!!!!!!! NICE! I don't see it, but i can dream it!
