what is the last succedaneous tooth
|
Max. K9, molars are non-succedaneous!
|
|
which is the largest max molar
|
1st > 2nd > 3rd
|
|
in maxillary posterior teeth which dimension is largest
|
FL>MD>IC
|
|
IN max. molars how do the buccal and lingual cusps differ in size
|
buccal cusps are closer to the same size and lingual susps differ in size
|
|
true or false max molars have one buccal and one lingual cusp
|
true
|
|
how many occlusal pits do max lolars have
|
3: mesial, central, distal occlusal
|
|
how many total pits will you find on a max molar
|
5 pits. one buccal, one lingual and 3 occlusal
|
|
how many root branches do max molars usually have
|
3, Lingual>mesial buccal> and distal buccal
|
|
These teeth have a rhomboidal or heart shaped occlusal view
|
max. molars
|
|
how do you tell the right from the left tooth on max
|
mesial buccal root is broader than the DB
|
|
Describe the dimensions of the mand. molars in comparison to max molars
|
Mand. molars are wider MD > FL and Max molars are wider FL > MD
|
|
how many cusps do max molars generally have
|
4 cusps
|
|
how many cusps do mand. molars generally have
|
4-5 cusps both lingual cusps nearly the same size
|
|
is there a lingual pit on the mand. molars?
|
no lingual pit but 1 or 2 buccal pits
|
|
why are there 2 buccal pits on the mand. molars
|
this is the terminis of the mesial and central grooves
|
|
how many root branches and pulp canals will you find on a mandibular molar
|
2 root branches but usually three pulp canals
|
|
which root has 2 pulp canals in mand. molar
|
Mesial root will have 2 pulp canals
|
|
how do the number of roots found on the maxillary molars compare with mandibular molars
|
Max. molar has 3 roots, L>MB>DB
Mand. molar has 2 roots, Mesial root is broader than distal root and the mesial has 2 pulp canals |
|
from an occlusal view, wher are the proximal contacts of posterior teet located relative to the facio-lingual midline of the crowns
|
buccal
|
|
what is the geometric outline of a max molar in comparison to the man molar... and why is this so
|
max molar = trapezoidal
man. molar = rhomboidal why? b/c the mand. teeth must fit into the maxillary arch |
