300 Dental anatomy facts to know cold Flashcards
The primary tooth that has the most distinctly prominent facial cervical ridge is
Mandibular 1st molar
The lingual cusp of the maxillary premolars is off set to
the mesial the first more than the second.
The primary second molar generally exhibits
cusp of Carabelli
Mamelons that remain beyond the age of 10 generally
indicate an open bite
Mandibular central incisors and Maxillary third molars generally occlude with
only one opposing tooth.
- The developmental groove between the df cusp and the dl cusp of the mandibular 1st molar is
distofacial.
- The roots of the maxillary second molar tend to be
less divergent and have greater distal inclinations.
- The teeth whose function is primarily biting are
incisors and canines.
- The tooth with the longest root is the
maxillary canine
- The groove pattern for the mandibular first molar is considered
Y or Dryopethicus pattern
- The groove pattern for the mandibular second molar is consider
a cross (+) pattern.
- When compared to a maxillary canine the mandibular canine has contact areas located
more incisally
- The mandibular 1st PREmolar the mesial marginal ridge located more
cervical than the distal.
- The oblique ridge of maxillary molars
forms the distal boundary of the central fossa.
- A transverse ridge results from
the union of the facial and lingual triangular ridges.
- For multirooted teeth dentin continues to form MOST rapidly
at the floor and roof of the pulp chamber.
- Maxillary incisors are the only anterior teeth that are
wider mesio-distally than facio-lingually
- Mandibular Molars are the only posterior teeth
that are wider mesio-distally than facio-lingually
- Mandibular 1st molar usually has
two roots and three canals
- Mandibular 1st molars usually have
two mesial canals.
- The primary maxillary 2nd molar is the primary tooth that generally has
an oblique ridge.
- The mesiolingual cusp of the Maxillary molars occludes in the
central fossa of the mandibular molars
- The distobuccal cusp of the mandibular molars occludes in the
central fossa of the maxillary molars.
- The primary second molar exhibits more cusps
than the primary first molar.
- The occlusal outline of a mandibular first molar is a
pentagon.
- The lingual concavity of the maxillary anterior teeth is most influenced by the side shift of the
TEST
- The side shift of the mandible is also known as the
Bennett movement.
