Dear Friends,
lets start discussing NDEB II (American) & Canadian NBED questions and answers.
Students preparing for 2012
All the best, Good luck
Happy studying

1)A gingivectomy approach to pocket elimination results in:

a.healing by primary intention
b.adequate access to correct irregular osseous contours
c.retention of all or most of attached gingiva
d.none of the above
I think answer to be c

2)A surgical flap approach to periodontal pocket elimination permits
A. healing by primary intention.
B. retention of gingiva.
C. access to perform osseous recontouring.
D. All of the above.
I gusee answer to be D

3)The most important factor in determing the dosage of systemc fluoride supplementation is
1) daily water consumption
2) climate
3) water fluoride concentration
4) total daily fluoride intake
5) patients age

I think the answer to be 3,what say??

 

[bashg]

In a young patient living in an area with communal water fluoridation, the fluoride concentration of an erupted tooth is greatest

1. at the dentinoenamel junction
2. on the surface of the clinical crowns
3. at the layer of dentin nearest the pulp chamber
4. evenly throughout the enamel

I belive the ans should be 2 on the surface of the clinical crown?? not sure
but what say

 

[bashg]

Furcation involvement can be treated by

1. root planing and oral hygine instruction
2. periodontal surgery with osseous and or tooth recontouring
3. root resection
4. antibiotics threapl only

A) 1,2 & 3
B) 1 & 2
C) 2 & 4
D) 4 only
E) all of the above

i am confused as to if antibiotic therapy should be given in this, if not then the answer should be A and if it is to be included then the answer should be E.
can anybody please guide me through??

 

[bashg]

In periodontics, the best prognosis for bone regeneration follows the surgical treatment of
A. suprabony pockets.
B. one-wall infrabony pockets.
C. two-wall infrabony pockets.
D. three-wall infrabony pockets.

I am confused between A and D.
since suprabony pocket had only horizontal bone loss,there are chances of it to regenerate first. but if we look at only infrabony pocket then the answer should be D HELP !!!!!

 

[bashg]

in a patient with advanced periodontitis mobile teeth should be splinted in order to:

1. reduce gingival inflamation
2. accelerate epitheliazation after periodontal surgery
3. enhance formulation of a new connective tissue attachment after surgery
4. noneof the above

could it be 3??

 

[bashg]

The treatment of choice of a deep pocket whose base extends beyond the attached gingiva is

1. gingivectomy
2. mucogingival surgery
3. root planing
4. none of the above

could it be mucogingival surgery??

 

[bashg]

The best prognosis for new attachment (reattachment) of periodontal ligament is in

1. narrow infrabony pocket
2. narrow suprabony pocket
3. wide infrabony pocket
4. wide suprabony pocket

I have no clue for this, can some body give me an answer with explanation would really appreciate it😕

The answer should be wide infrabony pocket, because new attachment or reattachment should form in infrabony pocket if we look at the definitions of both (it is the reunioun of connective tissue with a root surface) and wider the angle between the root surface and defective wall the less the chances of repair or regeration. The link supporting this wide issue is as below pg130

pls correct me if i am wrong

 

[bashg]

The most objective measurement of successful scaling and root planing is
1. reduction of pocket depth.
2. root smoothness.
3. absence of plaque.
4. absence of bleeding upon probing.
5. increased sulcular fluid flow.

A. (1) and (5)
B. (2) and (4)
C. (1) (4) (5)
D. (1) and (4)

iI think it should be B but not sure, coz for root planng i rebr my teacher cheking 4 root smoothness. plz guide me through
i cannot find a good refrence to find a proper answer

 

[bashg]

Calculus contributes to gingival inflammation by:
A. having a porous surface.
B. having cytotoxic bacterial products.
C. favouring bacterial colonization.
D. all of the above.

should the answer be only C or D plz help me

 

[bashg]

in the oral cavity decalcification of enamel occurs only through
1)proteolytic enzymes
2)loss of calcium
3)sulfuric acid
4)hyaluronidase

HELP
