Canadian EE Released Test Item Bank

[brain in dds]

Hey Friends,

i'm starting this new thread only limited to Released Qs released by NDEB of Canada. They 660 pages looooooooooooooong!
So, another platform for all EE students to dance on and get each other's help in getting the right answer!

Good Luck!

in ankylosis the mandible is deviated to the unaffected side
am i correct

ankylosis in the mandible will deviated to the affected side...i think..this was the only answer that made sense

 

[brain in dds]

ankylosis in the mandible will deviated to the affected side...i think..this was the only answer that made sense

agree...
yeah, mandible will deviate towards the unaffected side only in case of hyperplasia.

do correct me if it is wrong, plz!

Hi

just wanted to cross check regarding APF( apically positioned flap)
can it be done on palatal side or not?

also if do APF: palatal side you would need to trim the margins of flap to proper length during procedure. what does this mean/ relate to?

can anyone explain pl

thanks!

Hi Sarna/ Teethie:

This is the info on the deck on Glutaraldehye: Hope it helps

How long does it take to kill bacterial spores when a dental instrument is place in 2% sloution of glutraldehyde?

ans: 10 hours
2% glutraldehyde is an alkalizing agent and highly lethal to essentially all microorganisms, if sufficient contact time( 10 hours ) is provided and there is an abscence of extraneous organic material.

Advantages

Most potent category of chemical germicide
Capable of killing spores ( after 10 hours)
EPA registered as a chemical sterilant
Can be used on heat sensitive instruments

Disadvantages
Long period for sterilization
Allergenic
Not an environmental disinfectant
Extremly toxic to tissues

In hospitals, G are used to sterilize Repiratory therapy equipment
Alcohols, Chlorex and QA compounds are disinfectants.

High level disinfection is a process in which chemical sterilant are used in a manner that kills vegetative bacteria, tubercle bacilli,lipid nonlipd viruses and fungi BUT not all bacterial spores, if they are present in high number.

High level disinfectants: Glutraldehyde/ sodium hypo

thanks!!

Dr. Puris post info :

Thanks Jasmine, but according to this, option nr.4- minimal effectiveness against spores is also true... So answer- all of the above? Also how it has minimal effect to pulp if it is highly toxic?

Some more q: Please answer & pl explain

There are 2 normal children of the same age and sex , In one all permanent teeth except 3rd molars have erupted. In the other no permanent canines or premolars have erupted.

How old are these children??

Parents distressed of a 4 yr old child because of the thumb sucking habit that has resulted in app: 3mm in an anterior open bite, Most authorities agreee that parents should do what?

Stop worrying about habit
Do their best to break the habit of child
Have dentist contruct an appliance to stop habit


Space closure is LEAST likely to occur following early loss of :
primary maxillary 1st molar
primary maxillary 2nd molar
