[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!

Hey all,

As we are getting 2 different opinions on this q, wanted to find out the right answer.

54) what happens if there is a premature exfoliation of a mandibular primary canine ?
the mandibular incisors would move distally and lingually
decrease arch length ??
shift midline to affect side
need space maintainer

Deck: Ref:
The premature exfoliation of primary canine indicates an arch length deficiency.
The premature loss of a primary mandibular canine : Lingual collapse of mandibular anterior teeth.

in case of early loss of single primary canine....
in this circumstance, arch length shortens as the incisor teeth drift distally n lingually.

now wht do u think, folks?

.digitalis can lead to
a. hypokalcemia
b. hyponatremis
c. hypocalcemia.

The mechanism of action of Digitalis is brought about ( in the treatment of heart failure) by the inhibition of the Na/K , Mg dependent pump in the myocardial cells, which results in a transient increase of the intracellular Na, which in turn promotes Ca infflux via the Na/Ca pump leading to increased contractility.
Digitalis toxicity is increased in the conditions of electrolyte imbalance like Hypokalemia, hypomagnesemia, and Hypercalcemia ! Hence digitalis leads to hypokalemia.

[eebigdog]

It's all explained in Peterson's ...the orthognathic surgery part

and i guess the answer is to correct the deepbite

 

[eebigdog]

As for the above, all answers are good except :

[SIZE=-1]B[/SIZE]est success rates for implants ...it goes like this : (from best to worst)

[SIZE=-1]anterior mandible, posterior mandible, anterior maxilla, posterior maxilla

[/SIZE][SIZE=-1]Cyst has more chances to displace neighbor teeth :

Lateral periodontal

Finish line of crown over amalgam should be placed at 1 mm below
[/SIZE]

Hi Sarna, well regarding this question about GI :
in composite resin restoration GIC can be used a s base because they are
a.sedative to pulp
b.neutral in color
c biocompatible
d.compatible with the expansion of resin

i have not read any where that it says GI has sedative effect !!and if we look at the options we can eliminate B and D and we have to chose either A.sedative or C.biocompatible. and as i think that,any other dental material which can be placed in contact with living tissues whithout causing any harm is Biocompatible, but is not necessarily sedative.
i always put GI underneath resin composite in deep restorations so i spare the the thin dentin layer above the pulp from being etched and boned PLUS GI is caries-protective, releasing fluor ions prevent bacterial accumulation and pulpal irritation. in some cases,patients return complaining of pain after placing a composite obturation without GI base, and once i redo the obturation putting a GI base underneath and then composite obturation, the pain is gone. thats why it implies to me that GI has a sedative effect.
but u made me rethink and i searched in many books. In my university books say that GI r biocompatible and caries-protective. and the acidity is very low and it is neutralized after the mixing is complete
In Art and science of operative dentistry book i found that they recommend placing Ca(OH)2 always when the residual dentin layer is less than 0.5 mm, in spite of the self-limiting initial acidic effect of the GI.

in other books wherever i read sedative they mean Ca(oh)2.

I need a definition and example for a Biocompatible material and for a Sedative material !!

Hi Rachel,
I appreciate you are willing to discuss things. I thought you found it somewhere that GIC is sedative to pulp, and maybe this was another thing I should have read and remembered, but did not. The exam is in 6 days and I feel my head is boiling....
Anyway, I don't think GIC has any sedative properties as such and I have never been taught that. Answer biocompatible makes sense to me.
What kind of expansion did they have in mind. Thermal?

hi star jasmine,

had chosen the answer frm the research study online n now after reading yr post, i searched fr some other material and i found something related to arch alignment.... well, after reading thru all these... i think leveling curve of spee actually opens up the bite... therefore, correction of deepbite sounds good to me.

How do you support staining from tetracycline during mineralization? Do yoy have any referrence ? I found material that tetracycline can cause enamel hypoplasia and discoloration, I think it affects the apposition stage, the production of the enamel.

Sarna, I think that enamel pearls is the right answer.If there is enamel projection in the bifurcation there is no way you can treat periodontitis.

How do you support staining from tetracycline during mineralization? Do yoy have any referrence ? I found material that tetracycline can cause enamel hypoplasia and discoloration, I think it affects the apposition stage, the production of the enamel.

Sarna, I think that enamel pearls is the right answer.If there is enamel projection in the bifurcation there is no way you can treat periodontitis.

Thanks Leda, I was thinking about enamel pearl too, but I still get a few answers wrong in Web assessment and I thought it was one of them..

As to tetracycline staining I could not find any reference, but I think it is mineralization/calcification but I don't know what difference is between them- for me it is the same thing. Tetracycline can be deposited in bones too so I think it is not aposition
Has anyone info in this matter??

enamel pearl and projections are corrected with odontoplasty but when you have narrow furcation, cleaning is very difficult which decreases succes of perio

mineralisation is the same as calcification.
there's a page in Mosby's review for part II , i think it's in pedo/ortho section with teeth calcification dates
Tetracycline will stain teeth if given from 4-6 month in utero till around 8 years of age (except for third molars)
It crosses the placenta and it's deposited in teeth and bones
Teeth appear fluorescent under UV light

no i have no article for sloughing, thats why I did not mark my answer as 100% sure ,
are you sure of distortion of tissues?

I haven't read it anywhere, but it felt logical to me and also I did not see any connection between amount of anesthetic and sloughing....
