yes it is true, because of small lingual cusp on 1st premolar. thank u pb2007 for posting this.
svetlana, add this to your exception list too.

in packet M ques no 138 says
lingual embrasure is smaller than facial in
mand 1st and 2nd premolar,is it true??

 

[Cindrella]

Help please !!


1. If the respiratory quotient is 0.7, the primary energy source is:
Options -fat, ketone bodies, glucose, etc. 🙁
2. What increases the affinity of Hgb for oxygen?
Options - Increased pH- ANSWER ?, temp, etc
3. lingual a's relation to hyoglossus ms. is deep ..right ?
4. which ms depresses lat borders of tongue? Ans- hyoglossus
5. which nerve fibers travel throughout the course of the ling n to receive sensory input from ant 2/3 of tongue? Ans - Chorda Tympani ?
6. secretory IgA protects the mouth from S.mutans by: Ans- preventing invasion of mucous memb

If the lingual cusp of Mandibular 1st PM is small... how can the lingual embrasure be small ... ? It should be wide 😕

 

[Svetlana]

Is it right that Max.M have 3 major cusps
Mand.M - 4 major cusps
?

 

[Cindrella]

A few more --

1. which detergent eliminates lipophilic and nonlipophilic bugs?
2.which is the most likely cause of GI cancer? Villous adenoma, duodenal ulcers
3.where are submucosal glands located? Duodenum, stomach
4.Nerve Supply For Circumbvallate Papilla ?
5.PAPILLOMA VIRUS 13.16- DISEASE THEY CAUSE

Help please !!


1. If the respiratory quotient is 0.7, the primary energy source is:
Options -fat, ketone bodies, glucose, etc. 🙁 it's fatty acids and for glucose=1
2. What increases the affinity of Hgb for oxygen?
Options - Increased pH- ANSWER ?, temp, etc right
coz Hb will not release oxygen(dissoc,curve to the left)
3. lingual a’s relation to hyoglossus ms. is deep ..right ? think so
4. which ms depresses lat borders of tongue? Ans- hyoglossus
5. which nerve fibers travel throughout the course of the ling n to receive sensory input from ant 2/3 of tongue? Ans - Chorda Tympani ?
Right!
6. secretory IgA protects the mouth from S.mutans by: Ans- preventing invasion of mucous memb

Right!

6,11-genital warts

 

[Cindrella]

Right!

Thank you 👍

[teethie]

because also the crown is tilted lingually. so embrassure is small on lingual side.
hop e this helps.

[teethie]

yes it can be true, if you go with talon cusp concept that u mentioned abt distolingual cusp of max molar.
mand molar Distal cusp is smallest.

Is it right that Max.M have 3 major cusps
Mand.M - 4 major cusps
?

Thank you 👍 ANother Q

Canine protected occlusion is a normal finding that we see in ideal dentition.. am i right ?

Group function is when some or all the posterior teeth are contacting on the working side only -- now this is when malocclusion is there right ? Cuz ideally in canine guided when the canine mandi overrides the maxillary canine etc ,no other posterior teeth are contacting !

IS my understanding ok ?

 

[anniemirza]

@CINDRELLA:
1- If post crossbite which cusps would contact in mediotusive movement.? -----I guess it would come into proper class-1 occlusion.(mediotrusive)
2- What syndrome is characterized by, increased succeptibility to infection, retinal infection?

A. Gardner sydrome
B. Hypothyrodism-anr???
C. Hypopitutaryism
D. Hyperthyrodism....
all the options are related to retinitis....?

3-What characterizes Albers-Jeheurs syndrome?-dint find anything regarding this

primary active transport-anything that uses ATP

 

[Cindrella]

👍 @ pb2007 and svetlana ... both u guys pls pls don't disappear from SDN after your exams.. pls stick around pls pls pls .... Thanking you in anticipation... i know u'll want freedom from academics for a while but pls do check this thread and answer as much as possible... Wish you good luck for the battle 👍

Thanks 👍

 

[anniemirza]

Thanks 👍

PRIMARY ACTIVE TRANSPORT -we discussed it few days back...active transport of potassium and sodium during transmisson of nerve impulse.
And regarding retinal infections...almost all the options are related to retinal infections...gardners syndrome,hyperthyroidism/hypo,hypopituitarism...they all cause retinal infections

3-What characterizes Albers-Jeheurs syndrome? ---CENDRELLA i know about Peteus jegher syndrom that it cause cancer pancreas, lung ,breast ovary ,,,and its favorite site that it affects is jejenum .... hope that what u want in case its PETUEZ JEGHER SYNDROM

4-Example of primary active transport is?-- Na/K pump !

5-Atrial depolarization is represented as what on EKG? P wave..agree

6-Ventrical repolarization is represented by what on EKG? T wave agree

7-Bacteria that causes green pus? Pseudomonas aueroginosa ...agree ,and its important to know that it givesa Fruity odor

8-Oncofetal antigens?---all i remember is that this gene is expressed in fetus development,and expressed by specefic cancer cells .....
Any one would like to add anythin on this ,,it would be helpful if someone can add to it !

Pls correct if iam wrong

cationic detergents inactivate lipophilic virus,i forgot the name ,anyone remembers it then plz tel
i think it was either herpes or hepatitis

If post crossbite which cusps would contact in mediotusive movement.?

annie i didnt understand what u wrote abt the above ques ,can u plz explain it a bit,my brain seems blocked now ...

mediotrusive movement is non workin so there should be no contact?? does this make any sense

 

[Svetlana]

how to calculate percentage of Adenine for ex.,if given others?

Is it right?
A+G=T+C
purines=pyrimidines

or

A+T=G=C
????

 

[Svetlana]

8-Oncofetal antigens?---all i remember is that this gene is expressed in fetus development,and expressed by specefic cancer cells .....

Im not sure,are they those Ag that we can find in amniotic fluid
Like alphafetoprotein,hCG...

 

[pb2007]

how to calculate percentage of adenine for ex.,if given others?

Is it right?
A+g=t+c
purines=pyrimidines

or

a+t=g=c
????

a=t
g=c
so if 3 are given see wat's the value for t ,should be same
can u pinpoint specific ques

Okie the key word here is POSTERIOR CROSSBITE(both sides)...so wen mandible moves lateral...in normal -mediotrusive wud be the lingual cusps of maxillary wud occlude the fossa rt...now in posterior crossbite,the mandi buccal cusps are already on the outer side...on mediotrusive they will move inside and occlude in class 1 position.
got it???i knw its confusin😛

AS you said.
The Q#130,1999
A=20%
T=30%
C=40%
G?

A+T(50)=G+C(50)

10

Ok
Thanks

 

[anniemirza]

thanku annie,i understood it👍👍

hehehe now are we goin on the wrong direction again!!!lol....Am i confused or r u confused!!?
ahhhh i ws right....edited it again!

 

[pb2007]

hehehe now are we goin on the wrong direction again!!!lol....Am i confused or r u confused!!?

omg annie,my brain stopped workin ,goin out now , will look at it again in a while .
oh god ....i jst cant stop laughing .

ur formula is absolutly rite for this ques svetlana,i though u were pointin to another ques i think 96 or 98 one .

 

[anniemirza]

omg annie,my brain stopped workin now i guess ,goin out now, will look at it again in a while .
oh god ....i jst cant stop laughing .

hahaha same here.....🤣.....but finally i guess i was right initially!!all that confusion arised becoz i think we wr thinkin it in terms of maxilla movin....n not mandible!!!phewww finally!

 

[pb2007]

Is it right that there is NO maarginal ridges on mand.inc???
1999#132

 

[anniemirza]

Is it right that there is NO maarginal ridges on mand.inc???
1999#132

thanx 4 bringing up this questn.dint know it till now that marginal ridges are seen on the lingual aspect of mandibular incisors!
👍

 

[teethie]

yes, because they have got indistinct lingual anatomy. ref: kaplan

pb2007 and annie: i enjoyed ur conversations a lot but i could not get what the question was and what the answer u chose😀

hehehe....yea teethie that was hell of confusion!!And the final answer is what i wrote initially to explain pb.its class-1 relation on mediotrusive.

 

[teethie]

is not it the isopropyl alcohol.

[anniemirza]

annie: marginal ridges are not seen.

marginal ridges are absent on incisal surface but they are present on lingual surfaceof mandi inci.checked out all the books!!
also +ve in wheelers.

 

[teethie]

no annie, i checke din wheeler, marginal ridge is only prominent on incisal edge mesial and distal are inconspicuous.

[Svetlana]

The contact area that is most nearly CIRCULAR is located
ans-mesial of the max.2nd PM

"Circular"-see it for the 1st time!
1999 #151

 

[anniemirza]

no annie, i checke din wheeler, marginal ridge is only prominent on incisal edge mesial and distal are inconspicuous.

precisely-words of wheelers: "on the lingual surface,the marginal ridges are prominent NEARthe incisal edges."
n even if it says inconspicuous...i guess the presence of a ridge is confirmed.

 

[teethie]

yes incisal ridge is there but marginal meaning mesial and distal are not well apppreciated.
so if question is not seen, it confirms the above lines too. asda wont ask exact words always.

precisely-words of wheelers: "on the lingual surface,the marginal ridges are prominent NEARthe incisal edges."
n even if it says inconspicuous...i guess the presense of a ridge is confirmed.

 

[Svetlana]

the max.canine has a midroot section outline which differs from the cross section of cervical area in...
1.more ovoid outline
2.more square
3.more rectangular
4.much greater facioling.dimension ans

coz i remember smth like cervical 1/3 the largest in max.or mand.canine...???
This ans.is right?

 

[pb2007]

is not it the isopropyl alcohol.

u r rite teethie
70%isopropyl alcohal is effective against herpes simplex coz it has envelope made of lipid layer{98 exm ques 78}

but the ques asked which detergent
so i wrote cationic ,see deck no 278 n plz confirm

 

[Svetlana]

there is no longitudinal groove on the mes/dist surface of the DISTAL ROOT OF THE 1st mand.M
???

1999#175

 

[Cindrella]

Thank you all for ur input ..can someone pls check deck # 109 dental anat

There seems to be something wrong at the bottom of the back of the card ( importnat point : The laterotrusive movement .... )

 

[Cindrella]

DECKS - dental anat - card # 56 {09-10} ( 2nd point on mandibular first molar root ) says crossection made apical to the bifurcation - we see,

kidney shaped canals in the distal

smaller , circular canals in the mesial...

shouldn't it be ,

kidney shaped canals in the MESIAL ( since 2 root canals are there MB and ML )

smaller , circular canals in the DISTAL...

pls confirm. This is not mentioned in dental deck correction page.

😕

 

[teethie]

well, i read here an d there all, but no options are given so can not comment which detergent. no reference found.

u r rite teethie
