What are the functions of the molars?
Mastication, maintenance of vertical dimension, supports cheeks, keeps tongue confined in arch
Which is bigger on all the molars? Mesiodistal or occlusocervical?
Mesiodistal
The molars are the shortest teeth in the mouth
For all molars, which are generally larger: medial or distal cusps?
Medial cusps
Where are the interproximal contacts?
Middle third
As you move from the first to the third molar, what happens to the roots?
The roots are closer together
How many roots does the maxillary molars have?
3
On the maxillary first molar, explain the inclination and the roots general appearance.
Inclines distally
Roots converge at the apex
Palatal root is the longest

What’s are the seven grooves visible on the maxillary first molars?
Central groove of the central fossa Buccal groove Buccal groove of the central fossa Distal occlusal groove Transverse groove of the oblique ridge Lingual groove Fifth cusp groove
Which root in maxillary molars has two or more root canals?
Mesiobuccal root
How many roots do mandibular molars typically have?
2
