Is anybody getting ready for the next eligibility exam in Canada or has anyone recently passed or almost passed IT. I hear that the next May exam is going to be pretty much easier that the passed ones and the ones to come. NEED SOME INSIDE INFO, LET'S SHARE, LET'S UNITE, LET'S KICK ASS :smuggrin: !!!!

Thanks for the answers eebigdog...thanks...I have a few more questions..Please help me if you can..

1) Allergy to latex gloves will fade after repeated exposure or not?
Ans. No

2) Baroreceptors are innervated by what nerves?
Ans. 9 and 10th cranial nerves

3) Healing of extraction sockets..is it primary intention or secondary intention?
Ans. Primary intention

4) Is codeine the only antitussive in the morphine family or other derivatives of morphine are antitussive?
Ans. Yes morphine have same antitussive action but we are not using it as it cause respiratory depression!!

Thanks again and most appreciated..

Thank you for the answers again..But I have a very simple yet confusing question to ask...

What is the antibiotic of choice for a patient who is allergic to Penicillin?
According to some literature it is Erythromycin, according to others it is Clindamycin and yet according to some other texts I have been reading it is Vancomycin..

Please what is the correct answer if we get this question on the EE exam?

Thanks again... And good luck on the test everybody...

Hi,
Why do u say Clindamycin and not Erythromycin I am pretty sure the ans for this is Erythromycin.Please explain.THANX!

"Clindamycin can be given to patients allergic to penicillins since there is no cross allergenicity"
This sentence is from Dental decks.

Can you explain your answer.....

Hi...According to my notes it is Enterococci...I hope it is right...

Sorry but could you explain.

As enterococci found most frequently in secondaryly infected canal, while in primary canal its Bacteroids, and if you talk about newly infected canal then its Streptococcus viridans.

Second thing in question, they didnt asked about microogranism found more in number in infected canal, they asked about microorganism found more frequently....and as well all know Streptococcus is most frequently found in caries and it also aerobic to facultative anaerobes, so it can survive in infected root canal even in anaerobic enviournment.....

Can you explain your answer .....
Thnks

Hi there....well as far as I know it was like that :
1) Effect of Caffeine : it's on cerebral cortex
2) Least irradiating is panoramic
3) Sugar in chewing gum is Xylitol

least hazard to pt. is MRI surely since its not ionized radiation from the begining
 
check this

"Clindamycin can be given to patients allergic to penicillins since there is no cross allergenicity"
This sentence is from Dental decks.

Can you explain your answer.....

Erythromycin is a macrolide antibiotic that has an antimicrobial spectrum similar to or slightly wider than that of penicillin, and is often used for people that have an allergy to penicillins. For respiratory tract infections, it has better coverage of atypical organisms, including mycoplasma and Legionellosis. It is also used to treat outbreaks of chlamydia, syphilis, acne, and gonorrhea. (THIS is from Wikipedia)

According to Pathway of the Pulp, Clindamycin is an apprppriate antibiotic for patients who are allergic to penicillin. It is beta lactamase resistant and is highly effective against orofacial infections. Erithromydin, which is commonly prescribed for pationes with an allergy to penicillin, has been shown to be ineffective against most of the anaerobes assoceated with endodontic infections. Thus it is no longer recommended.
New Dental Decks also recommend Clindamycin.:)

I think that amalgam can cause amalgam tatoo and this is not good in such esthetic important area as maxillary cental incisor. I prefer to cement the post using zinc-oxyphosphate cement.
Correct me if I wrong:)

Sorry but In this condition better to use Amalgam after raising the flap rather than using zincoxyphosphate cement... for explanation check ASDA papers...

Thanx!! If the decks recommend it then no point in discussing, the answer is clindamycin then.

C. over the buccal shelf area.
D. lingual to the crest of the mandibular ridge

I think the answer is A

The position of the teeth should be in neutral zone between the forces of the lips and cheeks from one side and the force of the tongue from the other side.
the mandibular posterior teeth shouldn't be placed too far buccally or too far lingually, they should normally be placed over the crest of the mandibular ridge (the central groove of the molars must be placced over the crest of the mandibular ridge with lingual inclination) and the mandibular anterior teeth are placed slightly labially to the residual ridge because the mandibular natural teeth are labially to their apices

could someone please explain in detail .Thanx!
 
hey plant this is what i think.. but others also help as i am not sure.. thanks buddy..put few more questions


..
1 A BITE WING Radiograph of an early mixed dentition should include the following proximal surfaces?

A) Distal of the primary canine to distal of permanent 1st molar.:thumbup:
B) Disatal of primary canine to mesial of permanent 1st molar.
C) Mesial of primay 1st molar to mesial of permanent 1st molar.

i think A

2 dietary deficiency of vitamin D can result in
A Abnormal formation of Osteoid:thumbup:
B Osteitis fibrosa cystica


3 Most ZOE Cements are not suitable for permanent cementation of crowns and fixed partial dentures because of
A High viscosity
B High solubility in saliva:thumbup:

4 An acute periapical abscess originating from a mandibular 3rd molar generally points and drains in the
A Submandibular Space:thumbup:
B Pterygomandibular Space
 
Can anyone help me with this question??

-accessory
-parotid
-submandibular
-sublingual gland

I could not find an answer in any book
 
phosphate related drug targets
