the enamel of the deciduos teeth develops partly before and partly after birth.the boundary between two portions of enamel in the deciduos teeth is marked by an accentuated incremental line of retzius or neonatal line or neonatal ring.it appears to be result of abrubt change in environment and nutrition of the newborn infant.

hey guys,,,here is a question drivin me nuts !!

which of the followin represents the correct size and characteristic of a nerve
fiber that conduct sensory input of pain from the oral-facial region ?

a. large diameter myelinated
b.small diameter myelinated
c.small diameter unmyelinated
d. large diameter unmyelinated

according to the asda answer is (c).......... but isnt it suppose to be small myelinated since its gona be faster in transmittin the impulse !!! or what i mean with myelinated its suppose to go fater to transmit the pain ??? or how !! can some one clarify this pls !!!!!!!!!!!

Thank you pb2007
Rapid heat sterilization will cause dulling of cutting edges rt?
Click to expand...
dri heat and ethyleneoxide are used wen sharp edges are important to maintain.
autoclave tends to dull or corrode sharp edges especially carbide steel.
for more info refer to kaplan notes chap 2 in micro .

hi wadent ,i think ada key is correct ,its small diameter ,unmyelinated coz group C fibres are pain sensing nociceptors which r umyelinated n small .
check this link http://en.wikipedia.org/wiki/C_fiber

wadent said:
thanks !!!

but here
C fibers are a type of axon that classifies its attached free nerve endings, which are pain-sensing nociceptors.[1] The other main classification of nociceptors is Aδ fibers.[1] These fibers have axons that are larger (1-5 μm), in diameter, are myelinated, and have a higher conduction velocity, which is on the order of about 20 m/s.[1]

now i'm myself confused abt th explanation ,this ques is drivin me crazy frm so many days n still th explanation is not correct,anyways i think i'l too jst mug it up in case its there on exm .

The correct answer is still C. I have seen that question and had the same doubt. So let me give you a hand with it. The pain fibers are two types. The first group are myelinated and responsible for the "quick pain" (you discussed them as Adelta) and the other group is for slow pain (unmyelinated) (group C). Now the question is asking you for the unmyelinated since they are the ones in the oral facial region which are abundant and actively pass the pain fibers. If they were asking you about the thoracic region - you have to choose B.

hey goodluck,,how u doin buddy..
well thats what i was thinkin (B) but the asda chose c!!! how why ??? i dunno

hey bombshell,,, well ok ...ur sayin c-fibers are unmylenated and they r slow pain,,,is that a feature of the oral facial region !!!!???????~!!!!!!! ,,i know its fast,,well thanks anyway..

There must be mistake in either asda or in decks.some one correct this

jst want to share this piece of info i found in 'monheim's local anesthesia and pain control in dental practice' .
a delta fibres r large myelinated n conduct fsat impluse .they r confined to the pregang autonomic fibres .no such fibres forund in dorsal roots ,therefore they hav no afferent function .so wer left with c fibres which r slow conducting small unmylinated .
which of the lesion is seen when facial nerve is cut right after its exit from stylomastoid foramen
1 ipsilateral loss of taste to anterior of the tongue
2 ipsilateral paralysis of facial muscles
malate aspartate shuttle
1]has one membrane carrier
2]transfers the elctrons of cytoplasmic NADH to mitochondria at a cost of one ATP molecule .
3]has similar role to glycerol 3 phosphate shutlle
4]transfers alpha ketoglutarate and aspartate across inner mitochondrial membrane via an antiport .

which glusoce can you elobrate little bit? any options?[/QUOTE]
sorry gudluck i dont hav options for this ,frm wat i hav read in kaplaN notes ,it says g6 pase is absent in muscles so muscle glycogen cannot serve as blood glucose .bt not sure if this is th answer

G6P may be the answer but it can be degraded in glycolysis.

but the wheelers page 312 says the answer is distobuccal.pls clarify
4.each of the following is the primary developmental cusp of the maxillary molar except one .which is the one?
mesiolingual
mesiobuccal

cusp of carabelli
please explain
5. when viewing the maxillary 1 molar from the facial aspect all major cusps are seen except?
mesiobuccal
mesiolingual-answer
distobuccal
distolingual
but wheelers page 266 says all the 4 major cusps are seen from this view.Pls clarify
6. which of the following morphological variation could have worst prognosis for existing peiodontal disease?

mesiobuccal
mesiolingual
distolingual
distobuccal -answer

if there is other option, answer will be distal cusp, mesiolingual is the highest cusp and then comes distolingual. DIstolingual is visible behind the disto buccal cusp , so it can not be the smallest.

thank you wadent, pbkal n teethie for the replies! Please come forward n clarify the rest. As thhethis says, if there's been distal then the answer be that for the smallest cusp in the mandibular 1 molar.
Pbkal, I hope the answers are for sure! Be lemme know the changes! Thank you all once again.
