one quick qn- are there mistakes in asda released papers's ans keys??
im askin this bcoz there were few qn whose ans in key were diff from what i have read.so i want to make sure if its betr to confirm the ans first or go along wid marked ans

 

[dentstudnit]

Yes,there are few,not always.
At the sametime,for few ques,we may feel asda ans is wrong.but there are some hidden informstion which we may fail to understand.So,better to confirm ur answers with the references.
hope this helps.

what syndrome causes increases susceptibility to infection
a/ Gardner's syndrome
b/ hypothyroidism
c/ hyperthyroidism
d/ hypopituitarism

plz i need the answer,my exam is within a matter of HOURS

 

[amolar]

I would say its Gardner's Syndrome. (familial colorectal polyposis).Not sure !!!!
Good luck on your exam

 

[dentstudnit]

a/ Gardner's syndrome
b/ hypothyroidism
c/ hyperthyroidism
d/ hypopituitarism--ans?

plz i need the answer,my exam is within a matter of HOURS

Is it hypopituitarism?coz,ACTH production is affected.
ACTH stimulates adrenal cortex to secrete cortisol which is antiinflammatory.So,decrease in cortisol -->infection(one of the complications)

 

[amolar]

Makes sense, and I was just reading about it too.

 

[amolar]

Q. which cusp is the smallest in primary mandibular 1st molar?
DF or DL ??

Thank You dentstudnit ;-)

Thank You dentstudnit ;-)

you are welcome🙂

i dont get it,decrease in cortisol --> infection
cortisone has ANTI-inflammatory effect,so an INCREASE in cortisol would stop the anti-inflammatory effect,hence enhancing the chance of infection
clinical correlate(patient taking glucocorticoids is more prone to infection than a normal patient)

 

[Playmaker83]

i guess i found it
lot of books are mentioning a relationship between HYPOthyroidism with susceptibility to infection
but yet didnt get the exact link between them,i guess it has something with the low metabolic rates of cells compromising the production of enzymes and hormones

yes hypothyroidism is the ans but couldnt find any explanation

can pls anybody tell m a source to read active tooth eruption?there r so many qns n im just guessin them

is this statement about dna true or false? - it is not confined to chromosomes (i think i shoud b true....like mitochondrial dna??/)
and also that in polyploidy,it is a multiple of normal chromosome content....(shouldnt this be chromosomal number instead of content??)

 

[generationX]

Is it hypopituitarism?coz,ACTH production is affected.
ACTH stimulates adrenal cortex to secrete cortisol which is antiinflammatory.So,decrease in cortisol -->infection(one of the complications)

by process of elimination a is the answer, i would think

 

[perfectionist1]

Would agree,its hypopituitarism....decrease in cortisol means more prone to infections....
N regarding glucocorticoids supress the immune...here is the thing...
There is a large amount of data indicating that steroids may have some effect(s) on modulating the immune system. As with most potential side effects, this is largely dose and compound dependant. There is strong evidence that different analogues produce vastly different effects on the immune system. Testosterone and certain analogues have been shown to be possibly immunosuppressive, while Nandrolone and other steroids are possibly immunostimulating. Both, however, have been found to be beneficial when given to AIDS patients, who clearly have an already compromised immune system. This is because the increase in lean body mass that those steroids can provide is consistent with an enhanced ability to fight off infections, enhanced survival rates, and a better quality of life. 👍

1. True...Nuclear DNA(Chromosomal DNA) and Mitochondrial DNA
2. Its chromosomal no. only...the no. of haploid chromosomes...3n....4n( isnt that chromosome content only)

hi.
please help me where i can get some good points on occlusion questions for quick review..i have my exam in couple of days and i am not so sure on this topic..

 

[dentstudnit]

hi.
please help me where i can get some good points on occlusion questions for quick review..i have my exam in couple of days and i am not so sure on this topic..

okeson is my only source for occlusion🙁.sorry fsi.

 

[fsi]

dentstudnit...which chapter u would say is the most impo...as i really dun have much time and the text in okeson is huge...i alredy did 1-2 chap but really not gettin occlusion question

 

[Gotaf]

Good luck to everyone who has exam in next few days...denstudnit, fsi, playmaker, R19🙂

 

[R19]

👍 thnx gotaf

 

[dentstudnit]

dentstudnit...which chapter u would say is the most impo...as i really dun have much time and the text in okeson is huge...i alredy did 1-2 chap but really not gettin occlusion question

1 and 2 chapter emphasize more on tmj anatomy.3,4,5,6 chapters are really good for occlusion.

 

[dentstudnit]

yes u r right !hypothyroidism seems to be the ans.
Though rarely thought of as part of the immune system, the thyroid gland plays a crucial role in maintaining the body's defenses. Hormones produced by the thyroid help regulate the metabolic rate within each cell and directly influence over 100 different cellular enzymes. With hypothyroidism, individuals routinely become more susceptible to viral and bacterial infections, especially those of the respiratory and urinary tracts.
Sinus problems, sore throats, middle-ear infections, tonsillitis, pneumonia, and other respiratory problems have gone from relatively rare conditions to common and recurring complaints. Business is booming for allergists and respiratory therapists all over the country, no longer just in "allergy-prone" regions. Middle-ear infections top the list of reasons for children's medical visits, and asthma has become so common among adults that it is no longer considered a childhood disease.
In terms of urinary infections, kidney dysfunction and failure can in many cases be linked to chronic infections of the urinary tract that were originally caused by an underactive thyroid.

cortisol impairs immunity--->prone to infections.hence decrease in cortisol will have the opposite effect.i got confused with the second statement 😀

 

[fsi]

I am bit confuse about some occlusion question can anybody please explain me what xactly this is about..
if there is a right movemnt so working side id right and non working is left..( simple)
confusion....
working side the contacting cusp slopes are: mx tooth lingual slope of lingual cusp against buccal slope of lingual cusp
i dunt know why im not gettin it..its in dr.kaims board review notes

 

[fsi]

in cross bite occlusion, the owrking and non working cusp are reversed for the affected teeth....not gettin itt... 🙁 plz explain

 

[fsi]

no one helping me out 🙁

 

[generationX]

in cross bite occlusion, the owrking and non working cusp are reversed for the affected teeth....not gettin itt... 🙁 plz explain

It is self explanatory if you understand what working and nonworking cusps are. Working cusps: Mandibular buccal and Maxillary lingual cusps in normal occlusion. In posterior crossbite situation, mandibular buccal cusps are buccal to the maxillary buccal cusps, hence the reversal of finctional role of the cusps.

hey dun get so tensed....refer okeson's TMJ ...its easy to understnd....no confusions there.gudluck.

 

[alzagoum]

@cindrella:
Ameloblasts will not differentiate from preameloblasts unless they

contact dentin... why can't it be this ?----------because it is not called predentin. if the option is predentin then it is the right answer.

are touched by odontoblast processes... ans by ASDA 👍
are touched by stratum intermedium
contact stellate reticulum
contact neural crest mesoderm

the answer for the amloblasts deffrentiation is somwwhat unclear. i have looked in books and journals and they all say that probably the stratum imtermedium affects the defreentiation of the preameloblasts to ameloblasts.

Hey
Would like to know what the difference between subnucleus caudalis of trigminal and subnucleus oralis of trigminal /!!
Thanks

 

[briansle]

Hey
Would like to know what the difference between subnucleus caudalis of trigminal and subnucleus oralis of trigminal /!!
Thanks

caudalis is pain. not sure what oralis does

 

[wdent]

Thanks Brainsle..
Saw this quest. in pilot exam came across ,,,but didnt know why they picked sub.nucl.caudalis...
Thanks

 

[teethie]

hi wdent, pl read okeson for this chapter 1 or 2. it is given in detail there.

Thanks Brainsle..
Saw this quest. in pilot exam came across ,,,but didnt know why they picked sub.nucl.caudalis...
Thanks

 

[wdent]

Thanks teethie..ill look at it when ever possible..

In ur owen words how can u explain it nucleus caudails and oralis ...anyway ill take a look

 

[teethie]

hi wdent,

subnucleus oralis-------THIS IS FOR ORAL PAIN MECHANISMS

subnucleus caudalis ,also called medullary dorsal horn

caudalis part is the principal brain relay site of nociceptors info arising from the orofacial region.
its called medullary dorsal horn too coz its continuos and structurally similar to spinal cord dorsal horn and it also extends into medulla .

Thanks teethie..ill look at it when ever possible..

[wdent]

Thanks Teethie ..
I got it now . 🙂

Hey Milestogo Best of luck for your exam!
I will try to answer these questions!
1. My guess is somehow D.replication
2. Should be A.pyriform fossa as it is a hidden cavity often missed and common for foreign bodies to lodge there.

3. Hmmm. This is tricky cos Primary max 2nd molar is similar to permanent 1st max molar so it should have oblique ridge and transverse ridge. By that logic so should permanent max 2nd molar. are you sure about this question?

I hope I am right about these! Would be great if someone else could also try answering these.

 

[MilesToGo]

Yes, I'm sure I copied everything correctly. Thanks so much for your help though!

is not functioing ? and why ?

 

[IMFdoc]

is not functioing ? and why ?

it is caused by paralysis of the 4th cranial nerve...superior oblique musle brings about the depression, abduction and intortion of the eye..
paralysis of this muscle will lead to hypertropia( upward deviation), exortion and slight inward deviation of the eye..
the patient have the habit to the tilt the head away from the affected side in order to reduce second image.

 

[start6030]

which tooth has the longest cusp ?

maxillary canine
or
mandibular canine ?????

 

[start6030]

i tried attempting asda papers... how would u co relate asda practice score out of 200 with a score in nbde ??

means , when should i start feeling confident of getting a score above 85 , if i try asda papers (with what score of some asda question paper )?

 

[chorea6]

1......diminished parotid salivation due to middle ear involvement...nerve mostly involved...ans lesser petrosal....y not auriculo temporal as it also supplies parotid
2..sensation of clogged ears is due to pressure on auditory tubes......nerve providing this sensory innervetion is......glossopharyngeal nerve....y not vestibulocochlear
3)female with bilateral pain in TMJ,ears clogged ringing sensation,..region of articular surface of TMJ not present...ans is proliferative zone

 

[start6030]

In position in the alveolar bone, the longitudinal axis of which of the following teeth is inclined toward the lingual?
