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

 

[drpuri18]

1 is the correct answer : mental injection for the primary mandibular second molar

I agree with ur ans. But sorry for my earlier ans as I read it wrong

Pl answer

2. why is it advisable to dispense the liquid component of cement of cement immediately before mixing?
a. to avoid absorption of moisture from the air
b. to avoid spreading over a large area of the slab
c. to allow tempering of the powder by the mixing slab
d. to reduce the temperature influence of the mixing slab
e. to prevent evaporation of the volatile components.

13 increasing the amount of water in the mix of an improved gypsum die-stone will MOST likely result in
which of the following
a. more expansion and more strength
b. more expansion and less strength
c. less expansion and more strength
d. less expansion and less strength

Which of the following causes bone loss?
1 C3a, C5a
2 Endotoxin
3 Interleukin
4 B glucorinidase

Correct it if anyone is wrong.

 

[kathrm]

Correct it if anyone is wrong.

I think 13 is more expansion and less stength

 

[Sarna]

I think 13 is more expansion and less stength

No, actually the more water the less expansion, ******ed setting time, weaker product- ref. Decks

 

[dentistgirl08]

Thanks Sarna!
Yes it is correct.
Increase in water: powder ratio: less expansion,less strength= weaker product, the crystals are further apart and have weaker forces of attraction btwn them.

2 questions

1. Epinephrine Reversal when you take an alpha Blocker? can anyone explain?
AND also what happens to beta 1 , what does it do?

2. Why is epinephrine containdicated with MOA inhibitors?


Thanks!!!

Thanks!!!

1. when an alpha blocker is taken it will block the alpha 1 receptors on blood vessels so there is no alpha 1 blocker fro epinephrine to act.. so thts why it will vasodialte instead of constrictin it..the bwta 2 vasodilator effect will be pronounced bcoz they are not blocked.......... i hope it will help...


2. bcoz moa will increase the conc of epi nor epi in the brain.. so when epi is given the toxic levels might be there. i hope it willl help/ correct me if wrong..

[dentistgirl08]

Thanks so much !!!

1. Methacholine
2. Epinephrine
3. Pilopcarpine
4. Physostigamine
5. Pralidoxime

Pl can anyone answrs? and why?

whats the minimal # implants when doing full dentures in maxilla/mandle?
what's the minimal # implants in overdenture retained dentures?
what's the minimal distance that should be between implant and maxillary snus?
what's the minimal thickness of a ridge for a given diameter of an implant?

thanks a bunch

 

[briansle]

T3 i meant Tyneol 3. i think that is the answer.

PLease help another
question:

In a standard inferior alveolar nerve block, which
muscle is penetrated by the needle?
A. Buccinator.---i think this might be the answer, please correct me if i am wrong. http://www.drchetan.com/inferior-alveolar-nerve-block.html
B. Mylohyoid.
C. Superior constrictor.
D. Masseter.
E. Medial (internal) pterygoid.

Standard mandibular nerve block - The nerve is approached from the opposite side of the mouth by angling the syringe from the premolars on the opposite side. After piercing the mucosa and the buccinator muscle between the palatoglossal & palatopharangeal folds until hitting bone (the ascending ramus), the syringe is drawn backwards slightly and brought parallel to the width of the ramus, so that the needle lies lateral to the medial pterygoid at the mandibular foramen

 

[lotus982]

i think the answer is mand molars

 

[briansle]

best site for implant success?

ant mand

What is the last suture to ossify?

with class iii malocclusion growth does ANB decrease?

Which drug is most likely to cause damage to CN 8? gentamycin? etrythromycin?

What is the last suture to ossify?

pag 146 mosby said sphenooccipital,, and the first to have ossify is the intersphenoid

with class iii malocclusion growth does ANB decrease?

if malocclusion is class III ANB is increase and ANS is decrease I will not talk about that much because is more than a simple explanation but ANB line is going from porion to point B then if the jaw has protrusion or is more prominent than maxillary here the Line ANB will be longer than ANS line anyway depend of the case at I said is a lot to said here but if the case is protrusion of the jaw class III is increase

Which drug is most likely to cause damage to CN 8? gentamycin? etrythromycin? etrythromycin side effects are GI irritation such as diabetic gastroparesis or peristalsis and do not give this antibiotic to a patient with history of arrithmias.... that information is pag 171 and 173 of clinical microb. made ridiculously simple edition 4

please corret me if I am wrong... and about the first one is only my opinion from what I had read so if you find something else please tell me because I am not sure

Some q

Pl kindly answer:

1.Small white lesion patients whole life:
Hypercalcification during first 6-12 mon/
hypercalcification during natal/
hyper during primary tooth calcification

2.-Which tooth least surface area-?

3.-Most soluble: HA/ FA/ CA( carbonic apetite)

4.-If both primary molars are missing: what do u do?

5.-Upright a mandibular molar with lingual and omega loop what happens?-

Can someone also pl try & answer the IMPLANTS q posted by TBoz

whats the minimal # implants when doing full dentures in maxilla/mandle?
what's the minimal # implants in overdenture retained dentures?
what's the minimal distance that should be between implant and maxillary snus?
what's the minimal thickness of a ridge for a given diameter of an implant?

[odontologia]

best site for implant success?

Ant mand
post mand - not maxillary because bone is more porous/ think thickest bone which is on mand post

I had a ? on my test that had to do with if you are extracting one of the premolars (can't remember which but it was either first or second) which injection to give. answs were a. long buccal b. ia c. lingual d. infiltration e. a,b,c.

 

[mirell]

Some q

Pl kindly answer:

1.Small white lesion patients whole life:
Hypercalcification during first 6-12 mon/
hypercalcification during natal/
hyper during primary tooth calcification

most likely should be hypocalcification but if I have to chooce here I will said this because calcification stage of permanent tooth start with the birth

2.-Which tooth least surface area-? mandibular central incisor

3.-Most soluble: HA/ FA/ CA( carbonic apetite)

4.-If both primary molars are missing: what do u do? if have first molar permanet erupted is lingual arc... if do not have any permanent then wait until they get erupted and if the patient can not eat because of that a protesis RPD should be considered in this case untill molars get erupted and then place lingual arc

5.-Upright a mandibular molar with lingual and omega loop what happens?-
inclination retro or lingual of anterior teeth, that mean over tiltin of anteriors, and extruction of molars with no inclination of molars
Can someone also pl try & answer the IMPLANTS q posted by TBoz

hey guys, these were the questions i asked in a previous post, any response is appreciated
whats the minimal # implants when doing full dentures in maxilla/mandle?
what's the minimal # implants in overdenture retained dentures?
what's the minimal distance that should be between implant and maxillary snus?
what's the minimal thickness of a ridge for a given diameter of an implant?

 

[mirell]

whats the minimal # implants when doing full dentures in maxilla/mandle?

OK if is for a fixed detachable protheses will be 5 in the jaw and 6 in the maxillary mosby 320

what's the minimal # implants in overdenture retained dentures?
it is the same Q ?

what's the minimal distance that should be between implant and maxillary snus?
1mm ( pag 387 contemporary fixed prosthodontic) and mosby 80

what's the minimal thickness of a ridge for a given diameter of an implant?
this I dont understand
thanks a bunch

corret me if I am wrong

 

[TBoz129]

hey ok so i was just reviewing the decks, i think you need a minimum of 10mm for ridge height, i also think you need 2mm between max sinus and implant, not 1 (friend just told me that). the question regarding overdentures, i meant if you were going to retain teeth as overdentures for fixed and/or removable dentures is there a minimum?
and going back to the 6/5 for fixed retained...is this the same number removable dentures?

and going back to the 6/5 for fixed retained...is this the same number removable dentures?

well jejeeje you friend did read mosby?Ijust said what mosby said 100% sure that is 1 mm as minimun I even did give the page, listen Tboz do not believe even what I said , just go to the book and it will make you understand better and the other I will look for it then if nobody answere before because is not the same number to a removable because the number of teeth is only because the distribution of forces in occlution so if you have real teeth then you should need not the same number 🙂 but be careful with the interpretation because if you have a removable denture tissue holded with teeth in the mouth is not the same as removable implant holded in a patient with no teeth

 

[feelgood]

corret me if I am wrong

the rigde width for post portion for given implant is 1.5 to 2 mm more than implant width and for ant is 2+2 =4 mm more than implant width..

hw?
distance of implant from buccal plate .5 and lingul plate 1 mm mosby page 80

and ant 2 mm on each side.. dont remem where i read??????? probably in these threads somewhere..


correct me if wrong///

 

[UKdent]

hey guys, these were the questions i asked in a previous post, any response is appreciated
whats the minimal # implants when doing full dentures in maxilla/mandle?5 man and 6 max
what's the minimal # implants in overdenture retained dentures?2 man: 4 max

what's the minimal thickness of a ridge for a given diameter of an
implant?
1.5mm added to the size of the implant is minimum(.5mm buccal and 1mm lingual. 3mm added to the size of the implant is ideal(1.5mm buccal and 1.5mm lingual). ideal distance between implants is 3 mm. 1.5 between adjacent CEJ. but this is where they can trick you. in their 1.5mm is 1mm of bone and .5mm of adjacent tooth PDL space. so if they ask the question how far from adjacent lamina dura it would be 1mm.... if they ask how far from adjacent CEJ it would be 1.5mm.. this is for ideal... for minimum distance according to peterson is .5mm of bone. so when you add their .5mm of pdl space you would need a minimum of 1mm between CEJ. pay attention to minimum and ideal when the question is asked

Simple versions:
minimum for 4.1 mm implant: 6.1mm between adjacent teeth and ridge width of 5.6mm
ideal for 4.1 mm implant: 7.1 mm between adjacent teeth and ridge width of 7.1mm


what is the last suture to ossify? spheno occipital pg 146 mosby's (occurs after the age of 7)



All these answers are easily found in study material. I think every question asked here could be found in mosby's. You will learn so much more if you search for the answers yourself, instead of having someone just tell you, because i highly doubt you will be asked the exact same question. For instance if you looked up the implant questions in mosby's you would also learn that implants need to be 2mm superior the IAN canal, 5mm anterior mental foramen, 1mm inferior to maxillary sinus, 1 mm inferior to nasal cavity

Digitalis Toxicity can lead to hypokalemia because from the MOA of the drug it competes for the K+ ion at the same binding site at Na/K Atpase pump.

Biofeedback answer is E 🙂

Ok I have been using Mosbys, Decks, Kaplan, and First Aid and I am getting conflicting answers for the following...please Help..and cite.

1) location of 4th canal in mand molars?
2) most common/easily perforated wall on mand molar access (lingual or mesial??)
3)Most common missing teeth?? Is the Mand 2nd Premolar more commonly missing than the Max laterals???

Please help

hi sunshine. i am confused in these too coz man molars are abit tilted lingual and mesial. so both can be perforated during access prep.. but more likely is lingual and asda papres say....i think mesial is during instrumentation..most common mising is man/max 3rd molars man 2nd pm and then max lateral... and most commonly impacted is man/max 3rd molras and max canine.... hope it helps..

anyone to correct it !!!!!

 

[lotus982]

to demonstrate clinical effectiveness antimicrobial agent must demonstrate trat it
a. reduce plaque
b. reduce disease
c. kills aerobic bacteria
d. kills anaerobic bacteria

before toot prep, the dentist should visualize the outline form to:
a. establish convenience form
c. prevent over cutting & overextension
d. aid in finish of enamel walls & margins

incomplete removal of bact, pulp debris & dentinal shaving is caused by failure to irrigate troroughly, anther reason is failure to
a. use broaches
b. use a chelating agent
c. obtain straight line access
d. use gait glidden burs
