pls mention bout which primary tooth r u talking???? All??
If u would ask bout molar 1 st primary the answer is lingually

6 on crown of mandibular 1st molar , facial cusp ridge of ml cusp originates at cusp tip and normally terminates at which of following
a lingual groove
b halfway down the facial cusp
c halway down he lingual surface
d mesial portion of central groove(answer)
e ml occlusal pt. Angle area

where r these questions frm???

where r these questions frm???

These are unsolved previous questions of SDN

These are unsolved previous questions of SDN

which of following restoration is most likely to interfere with a patient physiologic maximum intercuspal position contacts -
a DL class 3 restoration on max right canine
b Mo on mandibular right 1st PM
c MOD on max. right 2nd PM
d Mo on max. left 1st molar


the answer to this question could be MO of mand 1st premolar resons:mand 1st premolar mesial marginal ridge is slanting at an angle of 45 degrees with the long axis. Also the rigde is at alower level ,lastly it is intrupted by themesial groove that extends from the occusal surface onto the misla surface.. charecteristic of mand 1PM. these feature make carivng difficult n obtaing the low lying slant usually result in hHIGH POINTS IN RESTORATIONS , LEADING TO INTERFERENCE IN MCP.

1 in protusive movement of mandible , which wall of condyle comes to lie against the slope of eminence -
a medial wall of articular fossa
b lateral lateral wall of articular eminence
---is it protrusive movement or lateral protrusive movement??coz i think it shud be lateral protrusive movement and on working side it is lateral wall of articular eminence and if asked on non working side then it is medial wall of articular fossa..

2 If mandibular cannine on right side is lost , how it effect protusive contact on left canine? ----no effect i think not sure

3 What is the cause of buccal vestibule to decrease in size when jaw is opened wide-
a condyle
b coronoid----answer
c humular
d styloid
4 which of following restoration is most likely to interfere with a patient physiologic maximum intercuspal position contacts -

b Mo on mandibular right 1st PM
c MOD on max. right 2nd PM
d Mo on max. left 1st molar----answer
5 In primary teeth which postion of crown is shorter occlusogingivally?
a mesially
b distally
c mid facial ----answer
d mid lingual
6 On crown of mandibular 1st molar , facial cusp ridge of ML cusp originates at cusp tip and normally terminates at which of following
a lingual groove
b halfway down the facial cusp
c halway down he lingual surface
d mesial portion of central groove------answer
e ML occlusal pt. angle area

correct me if iam wrong..

thanks for nice explanation
🙂

Thanks missiondds and aimshigh for providing answers but i have doubts

which of following restoration is most likely to interfere with a patient physiologic maximum intercuspal position contacts -
a DL class 3 restoration on max right canine
b Mo on mandibular right 1st PM
c MOD on max. right 2nd PM
d Mo on max. left 1st molar


i think MOD on maxilary right 1st PM because we have to prepare and restore both mesial and distal surface which can cause maximum problem



3 What is the cause of buccal vestibule to decrease in size when jaw is opened wide-
a condyle
b coronoid----answer
c humular
d styloid
Can u pls. explain this because i think with condyle lateral pterygoid is attached which helps in opening of mouth during and mouth opening buccal vestib
4 On crown of mandibular 1st molar , facial cusp ridge of ML cusp originates at cusp tip and normally terminates at which of following
a lingual groove
b halfway down the facial cusp
c halway down he lingual surface
d mesial portion of central groove------answer
e ML occlusal pt. angle areaule decrease in size.
according to me b should be answer

a DL class 3 restoration on max right canine
b Mo on mandibular right 1st PM
c MOD on max. right 2nd PM
d Mo on max. left 1st molar-----answer.
i think the answer is D because mesio-occluso surface of max 1st molar will be in occlusion with mand 1st molar and hence the restoration ll cause interference with max intercuspal position contacts.


3 What is the cause of buccal vestibule to decrease in size when jaw is opened wide-
a condyle
b coronoid
c humular---answer
d styloid
i think the answer is hamulus..coz i read that pterygomandibular raphe limits the buccal vestibule when jaw opens and pterygomand raphe is attached to hamulus of medial pterygoid...can any 1 confirm the answer


4 On crown of mandibular 1st molar , facial cusp ridge of ML cusp originates at cusp tip and normally terminates at which of following
a lingual groove
b halfway down the facial cusp
c halway down he lingual surface
d mesial portion of central groove------answer
e ML occlusal pt angle decrease in size.

the answer is D coz--if u imagine the ML cusp..it has 4 triangular ridges..mesial, distal, lingual and facial..the facial cusp ridge starts from tip of the ML cusp and slides down in between ML cusp and MB cusp and joins central groove mesially..


correct me if iam wrong
