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
