Dental Anatomy final cram Flashcards
What do we need to know about the mesiodistal length of the PRIMARY maxillary central incisor?
its MD is greater than its Crowth length
What do we need to know about the root of the PRIMARY maxillary lateral incisor?
the root is much longer in proportion to its crown

mesial slope
the permanent maxillary 1st premolar is the same ways
On the primary mandibular canine, which slope is longer? The mesial or the distal?
the distal slope is longer, this is opposite of the PRIMARY maxillary canine
Which tooth is bigger, the PRIMARY maxillary 1st or second molar?
2nd
Which tooth does the PRIMARY Maxillary 1st Molar resemble?
the maxillary permanent 1st premolar
Which too does the PRIMARY maxillary 2nd molar resemble?
the permanent maxillary 1st Molar
What is weird about the PRIMARY mandibular 1st Molar?
it does not resemble any other tooth - deciduous or permanent
Which tooth has the greatest cervical curvature of the CEJ than any other tooth?
the Maxillary Central incisors
Which tooth has the most variation (including being missing) other than the 3rd molars? What is the weird form of the tooth called?
Maxillary lateral incsors
weird form of the tooth is called a peg-lateral
Which anterior tooth hast the most distinct and deepest lingual fossa? Which means it also has the most prominent marginal ridges of all anterior teeth
maxillary lateral incisors
Which tooth has a MD length nearly identical to its LL length
Maxillary lateral incisors
Which tooth is twisted distally slightly on the root base to try to accommodate the arch of the mouth?
the mandibular lateral incisors
Which anterior tooth has the greatest LL dimension of the anterior teeth?
Maxillary canine
Which slope is longest on the maxillary canine, distal or mesial?
distal - because it is like the bulk of the tooth has been pulled distally
Which tooth has the greatest overall tooth length?
Maxillary canine
Which tooth has the longest root of all teeth?
maxillary canine
Which tooth has a vertical and centrally placed Labial Ridge?
maxillary canines
Which tooth has the longest crown of any other tooth?
the mandibular canine
Which tooth has the longest root of any mandibular tooth?
the mandibular canine
Which anterior tooth most frequently exhibits a bifurcated root?
mandibular canine
What is the relationship between the cusps of the Maxillary 1st premolar?
the buccal cusp is offset to the distal and the lingual cusp is offset to the mesial. The buccal cusp is taller than the lingual
What is on the Maxillary 1st premolar that makes it difficult to clean and difficult to adapt a matrix band to?
Mesial Developmental Depression
What is the identifying factor of the Maxillary 1st premolar? What does this identifying factor cause the root shape to look like?
it has a MesioMarginal Groove. This causes the root to indent on the mesial side and gives the root a kidney bean shape
Which non molar tooth most frequently exhibits 3 roots?
the maxillary 1st premolar
What is the relationship between the cusp heights of the maxillary 2nd premolar?
they are of equal height
Which tooth is the most symmetrical posterior tooth?
the maxillary 2nd premolar
Which tooth looks wrinkly?
the maxillary 2nd premolar
Which tooth has snake eyes?
the mandibular 1st premolar
Which tooth has a mesiolingual groove?
the mandibular 1s premolar
Why can you see more of the occlusal table from the mesial side of the mandibular 1st premolar?
because the mesial marginal ridge is located more cervicaly than the distal marginal ridge
Which posterior tooth is the smallest in the BL direction?
Mandibular 1st premolar
What is the shape of the occlusal outline of the mandibular 1st premolar?
diamond
What is the shape of the occlusal table of the mandibular 2nd premolar?
rectangle
What is the shape of the crown of the Mandibular 2nd molar?
pentagonal
Which tooth shows a Y, U, and H shape possibility? Which shape is most common?
the mandibular 2nd molar
the U shape is the most common
How many lobes does the Mandibular 2nd molar develop from?
5
The mandibular 2nd premolar in the Y shape has the same number of occlusal pits as which tooth?
maxillary 1st molar
Which premolar has multiple lingual cusps, a lingual groove and a central fossa?
the mandibular 2nd premolar
If you were congenitally missing a premolar, which one would it most likely be?
the mandibular 2nd premolar
which tooth has a root that approximates the mental foramen?
the mandibular 2nd premolar
What is the occlusal outline shape of the Maxillary 1st Molar?
rhomboidal
Which angles are acute and which are obtuse on the Maxillary 1st molar occlusal outline?
the distobuccal and mesiolingual angles are obtuse
the mesiobuccal and distolingual angles are acute
What are the sizes of the roots from biggest to smallest of the maxillary 1st molar?
palatal, mesiobuccal, distobuccal
What are the lengths of the furcations of the the maxillary 1st molar from shortest to longest?
M<b></b>
What are the 2 teeth that can cause problems for cleaning and matrix placement due to concavities?
the maxillary 1st molar - distal concavity
the maxillary 1st premolar - mesial developmental groove and root concavity
Which cusps does the oblique ridge connect on the Maxillary 1st molar?
the distobuccal and the mesiolingual
Which tooth has a cusp of carabellie and which cusp is it riding on?
it is the maxillary 1st molar - carabelli is riding on the mesiolingual cusp
What is the order of cusp size from largest to smallest on the maxillary 1st molar?
it is ML>MB>DL>DB
The maxillary 1st molar is wider _________ than _______ and wider _______ than _______.
wider mesially than distally
wider lingually than bucally
Which tooth does NOT follow the normal trend that lingual embrasures are bigger than buccal ones?
the maxillary 1st molar
Which tooth can be heart shaped or rhomboidal shape?
the maxillary 2nd molar
The cusps of the maxillary second molar look very much like the cusps of the maxillary 1st molar except for which one?
The maxillary 2nd molar has a small DL cusp
all teeth are developed from 4 lobes except which ones?
maxillary and mandibular 1st molars and
mandibular 2nd premolar with the Y shape
The mandibular 1st molar is wider _______ than ______
MD than BL which is opposite of the maxillary 1st molar
