mean is sum divided by n , median is arrange to ascending order and then take the center most , mode is the no which repeats max time

and nitrous oxide is 30% max

 

[dentalgirl1]

thanks DDS 1

Thanks a lot

 

[perav]

what is the mode of following data set?
1,1,1,1,2,2,3,3,7,9(n=10, sum=30)
a)1 b)2 c)3

what is mode and how it is calculated?
answer is 1

mode is the most frequently occurin number that is 1 . so mode is one

 

[perav]

and nitrous oxide is 30% max

are u sure it is 30% i think it is 50% according to umn website .

 

[dentalgirl1]

are u sure it is 30% i think it is 50% according to umn website .

50% is what I keep hearing, thanks for correcting

 

[DDS NO 1]

well i read somewhere in decks ,that 30% is max ...so perav or someone can you pls conform which is correct...

 

[perav]

the new (1999) International Workshop Classification of Periodontal Disease and Conditions.


WHAT IS THIS CLASSIFICAION

 

[godbless]

pardon me if I am hijacking this thread, but I wanted to see if anyone here knows how the percentile for part 2 score works?........if somone got 50-60% answers correct at least then roughly what percentile it translates to??
thanks

 

[perav]

10)ph of bacteria a)3 b)3.5 c)4 d)4.5 d)6

4.5

 

[perav]

nitrous oxide minimum dose not to exceed 50%

 

[godbless]

decks say 30% nitrous oxide is the safest max.

 

[cavity79]

mode is the most frequently occurin number that is 1 . so mode is one

nitrous oxide minimum dose not to exceed 50%

For what I know and sure about it... the max can give to patient is 2/3 of Nitrogen and 1/3 of oxygen. The machine already 'built in' with safety mechanism, at least 20 % of oxygen be given to patient. However, the max capacity of N2O will give more adverse than therapeutic effects. 30% is not enough to - only a tingling effect... the optimal anagesic effec is 40-50%, for most of the patient. But it also depend on the maximun lung capacity of patient's....look at lung physiology at part 1.. larger size..need more N2O.

More Than 50% will cause adverse effect such as.... nausea, vomitting and and finally, more than 2/3 will coz sleep for good

 

[perav]

what is the primary concern for treating dry socket ?

relief of pain
formation of blood clot .

Relief of pain...sometimes dry socket will coz more pain than toothache.

 

[dralana1977]

The tooth preparation for a porcelain veneer must create a/an
A. rough surface for improved bonding.
B. space for an appropriate thickness of the veneering material.
C. margin well below the gingival crest.
D. definite finish line

can someone help me with this questions? Is it A or D???

 

[dralana1977]

Acid etching of dentin with 10-15% phosphoric acid for 15-20 seconds
1. removes the smear layer.
2. increases dentinal permeability.
3. opens the dentinal tubules.
4. decalcifies the intertubular and peritubular dentin.
A. (1) (2) (3)??? is this the right one
B. (1) and (3)
C. (2) and (4)
D. (4) only
E. All of the above.

Can anyone explain this one for me???

it is all above
it does remove smear layer
by decalcifying the peritubular and intertubular dentin it increses dentin permeability for the formation of resin tags (hybrid layer ) and thus opens to tubules to receive the resin .

 

[dralana1977]

thanks Perav..for the clarification

The most likely cause of postoperative sensitivity with Class II composite resin restorations is
A. acid etching of dentin.
B. microleakage at the interface.
C. toxicity of the restorative material...no.
D. overheating during the finishing process...no

Sensitivity seems to be due mostly to polymerization shrinkage gaps, which allow for fluid flow and bacteria at the tooth/filling interface.

Post-operative sensitivity is presumably caused by minute fluid movements through open or unsealed tubules which are activated by temperature, osmotic changes, or by occlusal loads

I think it is B...but not a 100% sure...tell me what you think.

 

[dralana1977]

Can anyone tell me the amount of diastema that is considered normal in a 8 year old child???? I think between 2-4....8 I think is already considered an indication of some kind of pathology, but I could not find a source that gave an exact number.

yeh it shoul be microleakage .due to plymerization shrinkage or wear of the resin

sedatives in pregnancy ? last exam topic

 

[pendejodo]

Is Anybody Online

 

[perav]

as far local goes

lidocaine , prilocaine , septocaine , etidocaine r safe

Nitrous oxide , bupivacine and mepivacine r not safe .

i do not know about General anaesthtics .

diphhenhydramine is safe avoid diazepam and lorazepam inpg patient

 

[pendejodo]

Hello Bro Looks To Me That An Antihistaminic But The Barbiturics Were The Choices In The School Test Two Weeks My Test

 

[pendejodo]

Lippting Of The Prep ? Is Contraindicated Anybody Can Explain

 

[pendejodo]

Any Good Webside

 

[dentalgirl1]

I found a Jada article about sedation of pregnant women, it may be helpful.
part 2 may ask some questions about this.

[perav]

nitrous oxide has rapid onset of action because ?

it redistributes rapidly to fatty tissues
it has potent vasoconstrictor that promotes retention in brain
it has relatively low solubility in blood
it has high MAC value
none of the above

 

[pendejodo]

hello the problem is the only choice I kwon is not correct is benzidiazepins but the choices were category C may be or not you can give to pg women , thank you for your support ..................va

 

[pendejodo]

poor solubility is ok,,,,,,,,,,,,,http://www.pharmacology2000.com/Central/General_Anesthesia/GAobj3.htm#Nitrous Oxide

 

[pendejodo]

bro and sis keep the q caming .anybody has a q bank Q for part 2 is this good as part 1 . just asking

I think its C,low solubility in blood.

 

[mesh]

I think its C,low solubility in blood.

yea it is C you are right.

 

[MitPat]

I heard from my friends that Q bank from kaplan is nice but i dont have one, based on kaplan attitude of constructing their question i think the made it tough just so that to solve them you need to have lot of indepth knowledge , and some are really out of the world Q. If any one want to share wants to give an idea about it share it please.👍

 

[MitPat]

Do you want to share knowlwdge about implant position in both arch.
What is the distance to be spared in terms of mm if an implant is placed in premolar region,mesial and distally how much space should be left to make the implant successful.
thanks.👍

 

[MitPat]

what is the primary concern for treating dry socket ?

relief of pain
formation of blood clot .

It should be both as U need to relieve both but in the order, first pain, you can even give patient analgesic as morphine,percoset etc and second thing that can be done is make a dressing in the socket with Zno paste mixed with anesthetic agent in the market you will get in the trade name SULTAN paste,made in pakistan. Advise patient to keep the ext site clean with constant irrigation with the syringe, salt water gargle etc and hot pack form outside the cheek area. These are some important things that are done for DRYSOCKET.

 

[MitPat]

pardon me if I am hijacking this thread, but I wanted to see if anyone here knows how the percentile for part 2 score works?........if somone got 50-60% answers correct at least then roughly what percentile it translates to??
thanks

They say that the curve is around 15-20 percent on top of your actual score and different subject has different marking pattern so according to me try to answer as much as you can correctly and rest is your luck............Pray...thats all......destiny..!!!!!

it ill depend on how the question is framed .
if in a dental office then plastic by the hygenist
if at home oral care then it is super floss

 

[pendejodo]

Plastic is the answer also remenber the frase is the best they want the most generic anwser........I can believe nobady took the test yet++++++++anybady online most of the douths poeple had is 2006 test realesed is anybady outthere has the answer for 93 realesed with explanations or Q bank part 2 plase let me kwon ...........va

 

[MitPat]

You both were right as PLASTICS is the right answer in either way depending on the Q pattern.
Thanks much....👍

 

[pendejodo]

To obtain the best results when using an elastomeric impression material, the dentist must ensure that the prepared tooth is

very dry.
free of surface moisture why this is better choice anytaker

..111 which nerve would the ramus split osteotomy most likely damage? INF ALVEOLAR NERVE

for extracting of third molar, the following conditions would make the operation easier, except?
a. elastic bone
b. conical roots
c. soft tissue impaction
d. space within tooth bud is small I WOULD GO WITH THIS AS 3 RD MAOLARS R EXTRACTED WHEN THE ROOT IS 2/3 COMPLETED . NOT SURE

..119 the toxic effect of sulf ram is produced by which of its metabolites?
a. acetyl aldehyde
b. formaldehyde
c. glutaraldehyde

..124 what is the most definite way to differentiate ameloblastoma, and odontogenic keratocyst?
a. smear cytology
b. reactive light microscopy
c. reflective microscopy


I am not sure what is reactive light microscopy. But the most definite way to differentiate ameloblastoma and odontogenic keratocyst is by light microscopy in considering different types of ameloblastoma and specially unicystic type amelobalstoma with surface keratinization may be the best challenge in cyotologic smear. The key word is the most definite way. Do correct me if I am wrong.
