Part 2 Shuffled Flashcards
Largest root of max first molar
Palatal
Which non-molar tooth most frequently exhibits three roots
Max first premolar
Only tooth with a mesio-lingual groove
Mand first premolar
Only premolar with multiple lingual cusps
Mand second premolar - Y type
The occlusal outline of mand first molar
Pentagon
How to tell the difference between a right and left mand second molar
the mesial third has a greater F-L diameter
The maxillary first molar tends to taper towards which direction
taper towards the facial rather than lingual
The cervical cross section of max 1st premolar has what shape
Kidney shape - because of mesial concavity
Of the three furcations of max first molar, which is closest to the cervical line
Mesial furcation
Alignment of mand second molar crown
Inclines to the mesial and lingual - think of the larger mesial cusps weighing it downThis places the apex of the crown more facial, and the crowns more lingual
The mesiolingual cusp of max molars occludes where
in central fossa of mand molars
Mandibular first molar usually has how many roots and canals
two roots and three canals
If distolingual cusp is not present on max 2nd molar, describe tooth
3 cusp type heart shape
Cervical cross section of max first premolar pulp chamber floor has what shape
kidney shape
Only premolar with a lingual groove
Mand second premolar - Y type
Occlusion of lingual cusp of mandibular first premolar in normal occlusion
does not occlude
Nature of max second molar roots
less divergent-greater distal inclinations
Smallest cusp of mand first molar is
distal cusp
Which molar has the oblique ridge
max first and second molar
Angle of the mesial marginal ridge of mand 1st premolar
runs at a 45 degree angle because of mesial marginal ridge
Lingual cusp of mand first premolar is similar in development to what
cingulum of canine
Most congenitally missing premolar
Mand second premolar
Cross sectional outline at cervical of 2nd max molar is what shape
roughly triangular
Facial surface of mandibular molars in relation to border of ascending ramus
they are medial to border of ascending ramus
In the rare event of a second canal for a mand 1st premolar, it is most likely located where
to the lingual
Which premolar frequently only has one pulp horn
Mand first premolar
Cusp locations of the Y type mand premolar
one facial and two lingual cusps
Mand molars and border of the ascending ramus
Facial surfaces of mandibular molars located medial to the border of the ascending ramus
Which corners of max first molar coincide with direction of the oblique ridge
the obtuse cornersmesiolingual and distobuccal
Where is masticatory mucosa (attached gingiva) narrowest
facial aspect of man premolars
What is the most symmetrical posterior tooth
Max 2nd premolar
Y type mand second premolar has same number of occlusal pits as what tooth
Max first molar - 3 pits
Largest occluso-cervical dimension of any mandibular molar
Mand first molar
The facial cusp of the max first premolar is offset to what side
offset to the distal
Which tooth has greatest root separation of any other tooth
mand first molaronly two roots, less going on, more space, less distally and less crowded
Mesio-lingual and disto-facial line angles of max first molar from occlusal view
obtuse angles (of the rhomboidal shape)
Which max first molar cusp is not part of the the cusp triangle
distolingual cusp
Smallest facio-lingual dimension of all posterior teeth
mand first premolar
Which facial cusp ridge is longer on max first premolar
Longer mesio-facial cusp ridge (cusp tip offset to distal)-only premolar with longer mesial cusp ridge (along with primary maxillary canine)
Only Mandibular teeth that are wider mesio-distally than facio-lingually
Mand molars
Which tooth has a short central groove and lots of supplemental grooves giving it a wrinkly look
Max 2nd premolar
Smallest root of max first molar
distobuccal root(mesiobuccal root needs room for the 2nd canal (MB2), so it will be bigger)
Greatest distal root inclination of any other tooth
Mand 3rd molar
