When you see the mandibular molars from facial view which embrasures u can see
Facial and occlusal,
Facial and cervical,
cervical and lingual,
cervical and incisal
Teeth present with maximum inclination to plane of occlusion?

Members don't see this ad.

 

[make you smile]

1)Facial and occlusal

2)Mandibular first premolar

I think so,not sure.What are the answers given?

I think its Max insior.......... Mad first premolar inclenation of occlusal surface not whole teeth

1.Facial & Occlusal
2.Max Central Incisor

 

[krasnodar]

The largest embrasure in the anterior teeth is found Between:

Max central insisor
Max central and lateral
Max lateral and canine

Hi,are you preparing for the Nbde 1 exam?

 

[morphology]

The largest embrasure in the anterior teeth is found Between:

Max central insisor

pls confirm the answer again .....why cant it be facial & cervical ?

 

[Truth seeker]

i know its max central incisor from books wher did u get max canine as answer too, pls quote the source

Facial and cervical,
it will be facial and cervical sa we can't see the occlusal embrasure from facial view.


Max CI has maximum inclination facially from the sagittal view to the plane of occlusion.

nerve supply of the floor of the mouth？？？


nerve of mylohoid muscle
lingal n

 

[Katalyst]

nerve supply of the floor of the mouth？？？


nerve of mylohoid muscle
lingal n

Floor of the mouth constitutes the Mylohyoid and Geniohyoid muscles, therefore, Nerve to the Mylohyoid off the IA. Carries sensory and motor fibers. C1 ventral rami to geniohyoid muscle.

what r the other options?
mylohyiod nerve supply tot he maylohyoid and anter digastric
lingual to anterior third

may be in proximal

because thick ascending is in the outer zone
correct me if i am wrong.

please explain

its a percentage based question..
0.05% of F in 100
? in 1000000
=0.05x1000000/100
=500

a. cervical line of permanent teeth.

c. fissures.

18.. As the mouth is opened widely, the articular disk moves in what direction in relation to the articular eminence?
A Laterally
B. Anteriorly
C. Posteriorly
D. Medially
E. Superiorly

articular disc moves anteromedially as the lat pt moves in tht direction..



On the occlusal surface of a maxillary molar, the groove that representt the working path of the distofacial cusp of the mandibular molar is the
1. central groove.
2. facial groove.
3. lingual groove.
4. distal oblique groove.

remember this mandi moves in distofacial direction during lat working side movement...n maxillary teeth moves in mesiolingual direction...
