Section 1

Question Answer
The primary tooth that has the most distinctly prominent facial cervical ridge isMandibular 1st molar (note: cervical ridge is MF)
The lingual cusp of the maxillary premolars is offset to themesial (the first more than the second)
The primary maxillary 2nd molar generally exhibits acusp of Carabelli
Mamelons that remain beyond the age of 10 generallyindicate an open bite
Mandibular central incisors and maxillary third molars generally occlude withonly one opposing tooth.
The developmental groove between the DF cusp and the DL cusp of the mandibular 1st molar isdistofacial
The roots of the maxillary second molar tend to beless divergent and have greater distal inclinations.
The teeth whose function is primarily biting areincisors and canines.
The tooth with the longest root is themaxillary canine.
The groove pattern for the mandibular first molar is consideredY or Dryopethicus pattern

Section 2

Question Answer
The groove pattern for the mandibular second molar is considered to bea cross (+) pattern.
When compared to a maxillary canine the mandibular canine has contact areas locatedmore incisally
The mesial marginal rdige of the mandibular 1st PREmolar is located morecervical than the distal.
The oblique ridge of a maxillary 1st molarforms the distal boundary of the central fossa.
A transverse ridge results fromthe union of the facial and lingual triangular ridges.
For multi-rooted teeth, dentin continues to form MOST rapidlyat the floor and roof of the pulp chamber.
Maxillary incisors are the only anterior teeth that arewider mesio-distally than facio-lingually
Mandibular molars are the only posterior teeththat are wider mesio-distally than facio-lingually
Mandibular 1st molars usually have two roots and three canals
Mandibular 1st molars usually havetwo mesial canals.
The primary maxillary 2nd molar is the primary tooth that generally hasan oblique ridge.

Section 3

Question Answer
The mesiolingual cusp of the maxillary molars occludes in thecentral fossa of the mandibular molars
The distobuccal cusp of the mandibular molars occludes in thecentral fossa of the maxillary molars.
The primary 2nd molar exhibits more cuspsthan the primary 1st molar.
The occlusal outline of a mandibular first molar is apentagon
The lingual concavity of the maxillary anterior teeth is most influenced by the side shift of themandible
The side shift of the mandible is also known asthe bennett movement
The contact between a max central and lateral incisor makes thelingual embrasure larger than the facial
The non-molar tooth that most frequently has a mesial and distal pulp horn is themax central incisor
