NBDE II - questions discussions

[Life9]

Hi Everybody.

I am planning to take the NBDE II exam. Wanted to discuss some questions. Hopefully thru this we can help each other out.

Lets start:

Q1. Which antibiotic combination has the widest spectrum?
- Amoxicillin + clavulanic acid
- Pen V + tetracycline
- Amoxicillin + Metronidazole
- Erythromyicn + Tetracycline

which is most likely to result in pulp necrosis
a, intrusion---
b, extrusion
c lateral

 

[BENNY4567]

1 If anybody can pls clear, necrosis is due to intrusion or extrusion, as somewhere ans is int. and somewhere ext.

2 SYMPTOMS of pain and tenderness on palpation of tmj are usually associated with:
a impacted mand.3rd molars
b excitability of 2nd division of 5th nerve
c deviation of jaw to painful side upon mouth opening(ans)
But i thought ans to be b, if anybody can pls explain it.

-pupal necrosis is due to intrusion..plz check this link

a impacted mand.3rd molars
b excitability of 2nd division of 5th nerve
c deviation of jaw to painful side upon mouth opening(ans)
But i thought ans to be b, if anybody can pls explain it.
- i guess this is related to myofacial pain dysfunction where the pain is due to muscle affected and and there will be lateral deviation of jaw on opening towards the muscle affected.

 

[BENNY4567]

Thanx a lot aim high.
Can u pls explain this too
1 Resistance to proximal displacement in class2 is by:
a occusal dovetail
b converging proximal wall
c retentive grooves in proximoaxial line angle
Ans is a&c but don't we converge proximal wall too for resistance.
I have a confusion of how to learn retention, resistance forms for amalgam, composite, inlay and for differnt cavities as for class1,2,3,5.
There r so many diff. questions, can u pls clear my this concept.
thanx again

Resistance to displacement means RETENTION...
So now, for retention the ans is a and c.
ans b is for RESISTANCE..

I hope that helps..

 

[BENNY4567]

Thank u very much jaishrikrishan,
So if resistance to displacement is retention then wat is resistance?

 

[jaishreekrishna]

Thank u very much jaishrikrishan,
So if resistance to displacement is retention then wat is resistance?

i m not too good at explaining.. but i can try..

resistance to prevent the restoration frm breaking, like when occlusal forces
and retention means holding the restoration in position that means preventing its displacement...

 

[hydhaval]

I guess the ans is primodial cyst...

thanks

[ronu24]

I think E ( medial pterygoid )is the answer ,the needle lies lateral to medial pterygoid muscle during inf alv nerve block.

E is correct ans as meadial pterygoid muscle fibre are cross over there .

But if one can explain wen do we need to ground working and wen non-working cusps.

Hi,
1. An 84 year old father is accompanied by his 24 year old son to your dental office for
extractions and treatment, and the 24 year old son signs in the paperwork provided by your office as his legal guardian, what are the procotols of informed consent in this situation??

Can anyone explain this please?

2. 7 months pregnant women comes to your dental office in need for dental treatment, and as the appointment progress she is in syncope, how do you treat this situation? with respect to postioning of the patient.

Thanks

Nops dear,

its wrong It cannot be distal shoe coz the permanent first molar is already erupted.

Hi,
According to Mosby's `Unilateral loss of a second primary molar in the mixed dentition will usually require a bilateral holding arch.' Going by that, it will have to be the Nance holding arch. I hope it is right.

Hey,

Even I thought the same...thanks for clarifying my doubt.

Thanks a lot

Hi,
1. An 84 year old father is accompanied by his 24 year old son to your dental office for
extractions and treatment, and the 24 year old son signs in the paperwork provided by your office as his legal guardian, what are the procotols of informed consent in this situation??

Can anyone explain this please?

2. 7 months pregnant women comes to your dental office in need for dental treatment, and as the appointment progress she is in syncope, how do you treat this situation? with respect to postioning of the patient.

Thanks

Hi,
I think I can answer second question.
A pregnant woman can be placed on her left side with the legs slightly elevated to prevent problems caused by the weight of the fetus on the vena cava. The second critical step is to maintain an open airway, making certain that the person is breathing well.

Hi Star Jasmine,
answering your question as to the PM you sent, I am just going with the Decks(2006) and Mosby's. I am sure there are more materials if you have the time, but unfortunately, I do not have the time. I have only one month to study for the exam, and I don't think I can do more than these. I am doing my MPH, and my final semester starts the second week of August; which is why I have to give the exam as soon as the blocked period opens (September 1st).

A medium sized torus is observed in the mandible.The best form of treatment is..
1.to remove tori surgically
2.relieve the torus of pressure
3.cut thehole in the denture in the area of tori.
4.none of the above

thanks,
drpuri.

Can someone kindly answer with explanation: most of the questions have multiple answers.

1. In preparation for restoration with composite resin all cavosurface angles should be:
a. well rounded
b. right angles
c. acute angle
d. obtuse angles

2. Solubility of zinc phosphate cement is markedly influnced by:
a. powder/ liquid ratio
b.diet and oral flora
c. brand of material
d. age of patient

3. In which of the following ways is cast gold inlay superior to amalgam restoration
a. better adaptation to cavity walls
b. low thermal conductivity
c. better capacity to withstand forces of mastication
d. more accurate postioning of contact area

4. Which of the foloowing statements describe composite resins?
a. they can be placed and finished at the same appoint
b. more color stable than unfilled direct resins
c.similar to amalgam with coffecient of thermal expansion
d. finished surface tends to be rough

1. In preparation for restoration with composite resin all cavosurface angles should be:
a. well rounded
b. right angles
c. acute angle
d. obtuse angles
Beveling is indicated for composite margins to increase surface are available for etch. Beveling would create an obtuse cavosurface angle. (From Sturdevant’s Art and Science of Operative Dentistry – Chapter 6: Fundamentals in Tooth Preparation)

2. Solubility of zinc phosphate cement is markedly influnced by:
a. powder/ liquid ratio
b.diet and oral flora
c. brand of material
d. age of patient
A decrease in powder –liquid ratio decreases compressive strength, decreases film thickness, increases initial solubility, increases acidity, and lengthens setting time. (From Dental Materials Properties and Maniupulation by Robert Craig – Chapter 7: Cements)

3. In which of the following ways is cast gold inlay superior to amalgam restoration
a. better adaptation to cavity walls
b. low thermal conductivity
c. better capacity to withstand forces of mastication
d. more accurate postioning of contact area

Thermal conductivity of amalgam (0.055 cal/sec/cm2)
Thermal conductivity of gold (0.0710 cal/sec/cm2) (Not B)

Elastic modulus of amalgam (27,600 MPa)
Elastic modulus of gold (97,000 MPa)
Elastic modulus of enamel (83,000 MPa) (From same book as #2)

4. Which of the foloowing statements describe composite resins?
a. they can be placed and finished at the same appoint
b. more color stable than unfilled direct resins
c.similar to amalgam with coffecient of thermal expansion
d. finished surface tends to be rough
