The hemodynamics of flow in the tooth pulp are most likely analogous to those in the

1. heart.
2. lungs.
3. cranium.
4. liver.
5. gut.

hey friends,
please help me. The answer given is 3.cranium.I jus can't co-relate it.

what was the corelation that u where thinking about ,please explain
thanks

hemodynamics is the study of the flow of blood in the vessels. In tooth pulp the its the efferent n afferent vessels carrying blood .So according to me its the same tht happens in every organ.Whts the special about cranium n toothpulp???
May be i;m missing some gross point BUt thts wht m thinking.
Hemodynamics depends upon few physical factors like diameter of the vessel, peripheral resistance, viscosity etc.But how does it explain d above mentioned question??

i thought the answer was brain because the rq of brain is less i think 1 and rq of pulp is .7 that is the similarity so it is more or less similar

Ithink you are getting stuck with the definition to the word"hemodynamics".the question intends towards the analogy between tooth pulp and cranium.
*the pulp chamber and the cranium are enclosed cavities,
* both contain vital,highly vascular tissue and organ,
* if you imply your answer to this question by an exclusion criteria- the other choices have a dual circulation.
hope this helps.Please correct me if i'm wrong.

Thanx orthowiz
u r right 👍 . It just striked me. Both r the hard enclosed cavities.

That's right. #3 Cranium.

Both of these cavities (pulpal and cerebral) are enclosed cavities, bound by hard tissue/structures. This is a prime contributing factor to pain initiation in the pulpal cavity/tooth and the reason behind it's severity;
Increased circulation --->
Inflammation --->
Increased intrapulpal presure (no room for swelling) --->
Pressure on adjacent nerves ---> Call 1-700-DENTIST 😀

In addition to that, both cavities lack viable "collateral circulation". Although the cranium exhibits collateral circulation to some extent -circle of Willis- , it is usually impaired due to the build up of intra cranial pressure and due to the many end arterial branches. This would, from my point of view, be more relevant to the hemodynamics aspect of this question.

Good Luck !

Thanks nile .Great explanation.

Hello friends,

I want to know tht when one applies to dental school for advance standing program ,does the part II score matters for the admission??

I mean if two applicants are at same level in part I, GPA and did almost same in interview , then does the school considers part II score also or they don't even ask for it .

Thanks.

Part 2 candidate will be given preference
