2.temporalis
3.medial pterygoid

a linguogingival groove is most liek to b seen on

1.mesial
2.distal
3.midfacial
4.mid lingual

which of the ridges represents teh linear elevation extending between teh distoincisal angle and teh cingulum
1.distal
2.lingual
3.cervical
4.distal marginal
5.distolingual

which root branch of mandibular molars is normally teh shortest in length
1.mesial fo first
2.distal of first
3.mesial of second
4.distal of second

which of teh following represents teh most obvious difference between a primary max second molar and permanent max first molar?
1.primary tooth has 3 roots
2.primary tooth has a much narrower measurement at the CEJ compared to its contact area
3.permanent tooth has cusp of carabelli
4.permanent tooth has a rhomboid occlusal outline

 

[rashiarora]

the greater the horizontal overlap(overjet) of anterior teeth,then the
1.shorter teh cusps of posterior teeth
2.greater the intercondylar distance
3.lesser the intercondylar distance
4.more acute the Bennett angle
5.more obtuse the Bennett angle

teh bulk fo a tooth consists of
1.enamel
2.dentin
3.crown
4.pulp
5.cementum

which msl positions teh condyle in its most superior and anteriro position?
1.temporalis and sternocleidomastoid
2.temporalis and superior lateral pterygoid
3.masseter and digastric
4.masserter and medial pterygoid
5.medial pterygoid and sternocleidomastoid

eahc premolar has a mesial root depression except
1.maxillary first
2.maxillary second
3.mandibular first
4.mandibular second

when viewed from the sagittal plane and progressing anteriorly,teh axial inclination of anterior teeth
1.remains vertical
2.inclines facially
3.inclines lingually
4.inclines mesially
5.inclines distally

stability of TMJ is maintained by constant activity of teh msls that pull across teh joint.they are
1.posterior neck msls
2.suprahyoid
3.infrahyoids
4.depressors
5.elevators

shouldnt it be elevators??? elevators wil elevate adn the glenoid fossa will have opposite effect thus stabilizing the TMJ????

not sure though

 

[krasnodar]

can anybody excplain How and why :

teh bulk fo a tooth consists of
1.enamel
2.dentin
3.crown
4.pulp
5.cementum

what about Crown ( we say always bulky crown )

enamel- just on the crown
crown- half of the tooth
pulp- amount decreases with age
cementum- only on root
dentin below enamel and cementum alla round the tooth

 

[PaxRoma]

which of teh following msls has an imp influence on the function of the mandible,although its not a msl of mastication
1.omohyoid
2.geniohyoid
3.mylohyoid
4.digastric
5.sternocleidomastoid

If I can, I will complain about this question because which of the digastric muscle they mean? I consider anterior digastric part of the muscle of mastication group and the posterior digastric is not (which does affect the mandible function). bad question!
