Members don't see this ad.

i just cant imagine how in a laterotrusive movement(working,right or left) the lingual cusp of a maxillary second premolar passes thru the facial embrasure between the second premolar and the first molar as the decks state.
please help/just a week aaway.
am so worked up that i just cant think properly..

hey njsmahal looks like u r online now,
can u help with another doubt i had
its abt the superior an inferior heads of lateral pterygoid.
which is useful for the actions of the muscle??

 

[de297]

hpw is it that the crown of mandibular molar is tipped distally with respect to the long axis of the root
my understnading was that mandibular crowns are inclined lingually and mesially wrt the roots while the roots are tipped distally.and vice versa with the maxillary molars
someone please shed some light and enlighten me

mand. molar: crown: lingual/mesial

hey njsmahal looks like u r online now,
can u help with another doubt i had
its abt the superior an inferior heads of lateral pterygoid.
which is useful for the actions of the muscle??

the two heads insert in different locations. they act in a way that the capsule always stays on top of the condyle and doesnt stay behind. so the superior heads are inserted onto the medioanterior aspect of the capsule adn the inferior heads on the condyle...both move simultaneously

the roots are tipped distally and teh crown is inclined mesially... i didnt read this anywhere... will have to check and get back at it

 

[de297]

thanks guys
what abt the inclination of maxi molars??

 

[njsmahal]

thanks guys
what abt the inclination of maxi molars??

maxillary molars are inclined mesially and bucally

all the teeth have the tendency to shift to the mesial side so i am guessing they should be tilted mesially... but gotta check. coz in Ortho there was this line that if a tooth mesial to any tooth is removed... the tooth distally placed moves forward and moreover mandibular molars are generally inclined mesiallya nd lingually even if we see an x ray

For above questions -
Peridontium is best able to tolerate -

answer should be - to tolerate forces vertically [as oblique fibres resist forces acting along the long axis { masticatory forces } ] - its given in decks

Greatest value in determining the etilogy of oral ulceration -
i am confused between history of oral lesion or systemic evaluation
but prefer former as some frequent and common ulcers of mouth are apthous ulcers , canker sores reoccur during adulthood and some persistent ulcers [like more than 2 weeks ] indicate cancer

ok.. this question took way tooo much time from me..
i really dont have a clue..if i had to diffrentiate pemphigus vulgaris to bollus phemphigoid.. i would go for a smear..but since this question is more general..some tests will help us rule out diffrent casuse (like stress,malnutrition etc..) very quickly..but the gold standard may be a smear..again im not sure..

hi.. im not 100% sure if this the correct answer but in protrusion,condyles incline 30 degrees downword and forword..this first influence is the sliding movement of the mandible against the maxilla..it can also be ant teeth but first the influence is by the post relation..hope it made sense..;-)

the protrusive pathway of condyle ...means steepness of articular eminence.....it will affect the cusp height......not sure

hey i was right in the oral TB question. the most common is through self innoculation and not through the dental instruments... was reviewing it and found this. check it out.

The primary form of the disease most often is localized to the lungs. In most patients, the infection does not spread, and as host immunity develops, the caseous foci and hilary nodes undergo healing by fibrosis and eventually calcification. In a minority of patients, the progressive pulmonary disease spreads to the other organ systems through self-inoculation via infected sputum, blood or lymphatic system, establishing the secondary form of TB.

thanks .....but still confused!!!!!!!
the protrusive pathway of condyle ...means steepness of articular eminence.....it will affect the cusp height......not sure

ya thats what i thought.... and the question asks about RESTORING THE ANATOMY... the most probable right answer seems to be teh cusp heights... we cannot precisely measure the angles of the cusps... all we can do is approximate the height so taht we dont end up wit a traumatic occlusion in protruding movement.... same thing as overjet and overbite concept with cusp height.... but still make sure... thats what i think

and moreover the supporting cusps interact and guiding cusps dont occlude in the protrusive movement so i dont think there should be any effect on the inclines on those cusps.... gotta read that too....

 

[njsmahal]

the q is asking antiviral action against??????? it is against protein
it inhibit enzyme....and interfere with nucleic acid formation.
antivirals r both competitive or non-competitive inhibitor of enzyme

ok maybe i am confused between the terms action against and acting by ----- i think action against is for the product which is not being formed and acting by is what is the drug doing to cause the change.... like inhibiting the enzymes to act AGAINST formation of nucleic acids.. tahts what i was thinking....
can anyone put some light on that???

[njsmahal]

cant it be smear??they r asking for etiology,as in like herpes,tb,syphilis..then wouldnt smear be more appropriate??well thats how i interpreted the q.

cytological smears woudl yield various types of organisms normally found in teh mouth and hence it is highly non specific, histology can tell about hte type fo ulcer and underlying cause like whether it is punched out or smooth margins or crater like. lab tests i dont know what lab testst are they talking about and seems highly non specific.
what i though was that most ulcers are due to some underlying systemic cause and hence that seemed to be the answer but sinatra is one of the great brains who almost always proves me wrong... so i guess gotta search for this answer

hey everyone... my exam is in 8 days and im clueless on how to answer occlusion questions... for example

the dentist asks the patient to go into laterotrusive movement. the lingual cusp of #31 passes through the
1. ML cusp of #2
2. MB cusp of #3
3. lingual cusp of #4
4. MB cusp of #2
5. ML cusp of #3

how do i approach these questions?i tried but i just cant figure it out
.. also where should i study it from?

question 2

anterior guidance results in
1. postural vertical dimension and inter condylar distance
2. posterior cusp height and horizontal overlap
3. vertical and horizontal overlap
4. freeway space and intercondylar distance
5. posterior and vertical cusp height

 

[njsmahal]

failure of heart to show tetanus when stimulated is explained by automaticity isnt it??

automaticity is just htat if heart doesnt get input it will STILL contract

and heart muscle doesnt show fatigue coz it cannot be stimulated during refractory period or something like that...

the protrusive pathway of condyle ...means steepness of articular eminence.....it will affect the cusp height......not sure

upto my knowledge if the steepness of articular eminence increases , the cusps of mand. teeth will be longer i.e. longer cusps, deep fossa n more overbite.... narrow arch ?

correct if i'm wrong

1.medial pterygoid and masseter
2.digastric and masseter
3.temporalis and medial pterygoid
4.scm and temporalis
5.lateral pterygoid and temporalis

these two muscles place the condyles in most superoanterior postion.
CR defination---most superoanterior postion of the condyles in the articular fossae with the dics properly interposed.
also temporalis muscle have fibers that are oriented posteriorly predominantly elevates the condyle in a straight superior direction.
so most common med.pterygoid and masseter but also temporalis mus. responsible for CR.

these two muscles place the condyles in most superoanterior postion.
CR defination---most superoanterior postion of the condyles in the articular fossae with the dics properly interposed.
also temporalis muscle have fibers that are oriented posteriorly predominantly elevates the condyle in a straight superior direction.
so most common med.pterygoid and masseter but also temporalis mus. responsible for CR.

hi..
imo this is wrong..
CR is the position of condylle in their most unstrained position from lat movement can occur.the position is sup mos middle of the condyle in the fossa.

if u remember posslet diagram from icp to cr a retrusion needs to be occured.
main muscle to produce retraction is temporlais.. i would choose also med.pterygoid..(not sure in the second muscle)
