primary dentition
Letters (A-T) - CORRECT ANSWER- ✔✔Primary teeth are identified by _________
20 - CORRECT ANSWER- ✔✔# of teeth in the primary dentition
Premolars
3rd molar - CORRECT ANSWER- ✔✔Posterior teeth that are absent from primary dentition
Anatomic Crown - CORRECT ANSWER- ✔✔Portion of the tooth covered by enamel
(doesn't change)
Clinical Crown - CORRECT ANSWER- ✔✔Portion of the tooth that is clinically visible
(changes with age)
A= Anatomic Crown (does not change with age)
B = Clinical Crown (changes with age/different factors affecting gingival tissue) -
CORRECT ANSWER- ✔✔(A) Which crown?
(B) Which crown?
A = Young patient
B = Old patient - CORRECT ANSWER- ✔✔Which patient is older and which is younger?
, Proximal Surface - CORRECT ANSWER- ✔✔The place where the mesial of one tooth
contacts the distal of the adjacent
Between central incisors (midline)
3rd molars - CORRECT ANSWER- ✔✔Where would you find two mesial surfaces making a
proximal surface? What other teeth only have 1 proximal surface?
Axial Surface - CORRECT ANSWER- ✔✔What is the more generic term for mesial, distal,
facial, and lingual surfaces? (posterior teeth have 4 of these)
False (Triangular ridge of a distofacial cusp ) - CORRECT ANSWER- ✔✔True or false: The
arrow indicates a lingual ridge of the distofacial cusp.
False (Triangular ridge of the distolingual cusp) - CORRECT ANSWER- ✔✔True or False:
The arrow indicates a facial ridge of the distolingual cusp.
Oblique Ridge - CORRECT ANSWER- ✔✔A special transverse ridge which forms from the
union of the triangular ridge of the distofacial cusp and the distal cusp ridge of the
mesiolingual cusp.
Pure - CORRECT ANSWER- ✔✔In order to be a ______ transverse ridge, both ridges must
be triangular.

Primary maxillary 1st, 2nd molar - CORRECT ANSWER- ✔✔Where are oblique ridges
found in the permanent and primary dentition?
Lingual Ridges - CORRECT ANSWER- ✔✔A special ridge to canines that is NOT found on
