Correct me if i m wrong

 

[texas1286]

Thanks for correction .Can you give me example of concept of high validity and low reliability?

okay.. thanks. 🙂
1 more doubt😀

which of the following is a definite sign of traumatic occlusion
a. bone loss
b. gingival recession
c. wear facets 👍
d. food impaction


ans shd b wear facets jast becoz other choice shows sign of perio disease. then i would say wear facet can b seen in attrision.
can you give right answer with explaination?
repeat question..

why epinephrine is contraindicated in multiple sclerosis patient?

 

[texas1286]

Aspiration is not required in which situation?

1- anuerysmal bone cyst
2- simple bone cyst
3- hemangioma
4- primordial cyst
5- gaint cell granuloma





Answer is primoridial cyst . can any one explain reason for it?

 

[mmasurf]

well double check that answer cause you have to and it shows an amber aspirate read this page

http://books.google.com/books?id=dK...ook_result&ct=result&resnum=2&ved=0CDIQ6AEwAQ

 

[mmasurf]

the reason you don't give people with mulitple sclerosis epinephrine is because they are taking MAOIs antidepressants,which increase endogenous epinephrine, so you don't want to give them more epinephrine.

 

[texas1286]

well double check that answer cause you have to and it shows an amber aspirate read this page

http://books.google.com/books?id=dK...ook_result&ct=result&resnum=2&ved=0CDIQ6AEwAQ

So according to you what should be the answer?

 

[texas1286]

site specific characteristic menifestation associated with foolowing condistions

1- intra oral tuberculosis
2- syphilis
3- candidiassis
4- recurrent herpes simplex
5- histoplasmosis

 

[mmasurf]

every bone lesion needs aspiration but because the primordial cyst you can see its surrounding the tooth you have a good differential that its a primordial cyst compared to the other cysts.


as for your other question site specific is recurrent herpes simplex, its always on v3 while the rest can show up anywhere.

 

[mmasurf]

the answer is recession read this page

19) in releaving a buccle fenum from a mand. denture which muscle is released:
caninus 😕 (it is present in maxilla), orbiqularis oris, masseter

20) the best treatement of a diastma b/w the anterior 8 and 9 is:
proximal composite 😕, veneer, full crown, no ortho and surgery was suggested

21) the amount of the x-ray expsure that a fetusget in a single x-ray is
double the normal amount outside, half, less than 1 day that a person get in a day from outside exposure 😱

22) all of the following are the x-ray to access the bon in implant of 6 anterior teeth except
topography, pan, CT, periapical

23) patient come to yoru office and with multiple lesion around hte gingival, he mention he gets tired fast
multiple pyogenic tumor , leukima😕 , peripheral giant cell granula

its zoster which is on v3.. answer is intraoral tuberculosis but i don't understand reason.

treatment for periapical rediolucency and mid third fracture, periapical rediolucency and apical third fracture, periapical rediolucency and cervicle third fracture? can any one explain ?

 

[texas1286]

financial compromised patient, wants to restore the access opening into the pulpal spaces of the endo treated maxillary teeth. given this patient's history, the dentist would ideally proceed by

1) composite resto
2- amalgam resto
3- cast champher crown
4- endo post and champher crown



answer is 2

can any one explain because i think teeth which is already endo treated might be brittle so it is better to give crown.

What's the answer? It will help reason it out...

What does beveling a wax rim mean?

this question is straight from the post above. so niether i know the answer nor i understand question.. 🙁

 

[LazurasDC]

The only thing I can think of is that VDO and length are correct and you bevel to prevent any interferences?

 

[texas1286]

new attachment is reunion of connective tissue and root seprated by

ans is pathology

Can any one explain ? i think it talked about long junction epi which is form by rootplanning n scaling so ans should be iatrogenic😕

Hello part2 taker friends,

I have a question for you.
In new deck of prosthodontics part2, there was a question states that

Which of the following indirect retainers will provide the best leverage against lifting of the denture base?
options:

a)The one located the closest to the clasp tips which is located furthest from the edentulous area

b)The one located the furthest from the clasp tips which is located nearest to the edentulous area

c) The one located the furthest from the clasp tips which is located furthest from the edentulous area

And it says that correct answer is B.
but I feel the answer should be A...as indirect retainer should locate as far as possible from the distal extension.

Can anyone explain this?
If anyone has new decks, it is deck no. 152 - prostho section

Thanks.

here clasp tip is located nearest to the edentulous area 👍

 

[luckytooth]

I'm just wondering where can I find the questions related to the case study booklet in 2007-2008 decks.Do they have separate decks or is it combined with another subject? I'm unable to find it.

Please let me know,

thanks for the help.
So you also feel that answer should be A, right?

Yes.. n think you did nt understand it.. option A says- clasp tip is located closest to the edentulous area which is true and..... indirest retainer should b farthest from edentoulous area.. well i m nt good at explaining thing.. bt i tried

CORRECT ME IF I M wrong.....

 

[KiTmAn]

I just wanted to clear up this confusion that I had:

In the decks, it says - Using Ca-OH as a liner (such as dycal) for indirect pulp cap, promotes SECONDARY DENTIN formation.

However, in mosby's endo a lot of times it says Using Ca-OH will promote REPARATIVE DENTIN deposition. That, if im not incorrect is TERTIARY dentin.

secondary dentin is placed after closing of apical foramen and tooth is errupted and fxnal.

tertiary dentin is the reparative dentin produced in response to wear and irritants.

So that makes sense that Ca-OH promotes TERTIARY DENTIN aka Reparative dentin formation and not secondary dentin formaton..

is that correct? if someone can just clear this silly thing up for me that would be great

thanks

 

[2Dream]

This is what I found from Dorland's Illustrated Medical Dictionary

secondary dentin dentin formed and deposited in response to a normal or slightly abnormal stimulus, after the complete formation of the tooth. See secondary irregular d. and secondary regular d.
secondary irregular dentin dentin formed in response to stimuli associated with pathologic processes, such as caries or injury, or cavity preparation. Such dentin is usually irregular in nature, being composed of a few tubules that may be tortuous in appearance, and it often demonstrates cellular inclusions. Called also adventitious d., irregular d., reparative d., and tertiary d.
secondary regular dentin dentin formed in response to stimuli associated with normal body processes. Called also functional d.
tertiary dentin secondary irregular d.


In summary, secondary dentin can regular or irregular. When it is irregular, it is also called tertiary dentin.
Secondary Irregular Dentin = Tertiary Dentin = Reparative Dentin

Also, I found from the board buster book (pg. 403), "The composition of reparative and secondary dentin is same, except reparative dentin is more irregular and they differ only in location and deposition."

So, both Mosby and Decks are right but needed more clarification regarding which secondary dentin they were referring to.

I hope this helps. 🙂

oh ok..that makes perfect sense now..just going to remember that all 3 ..secondary irreg, reparative, and tertiary are the same exact thing...

thanks so much dream..appreciate it..

 

[dentiline]

Hey part2 guys,

Here I came up with few queries in ortho section.
Please help me out to reach to the correct answer choices..

1) which of the following orthodontic tooth movements is most likely to cause root resorption?
options: a- Translation
b-Extrusion
c- tipping
d- rotation...
Correct ans. is a- translation. but I have a doubt whether is this correct. I feel it should be c/d..
Can anyone explain this?

2) Ideal age of treating malocclusion is
a- 5-10 yrs
b-10-14 yrs
c- after puberty
d-at any age depending on the problem

correct ans is d... should not be it 10-14 yrs, mixed dentition period to treat malocclusion?

3)what is the treatment of choice for a lingually erupted maxillary incisor in a 7 year old with the rest of the occlusion in normal?
a- myofunctional appliance therapy
b- interarch elastic
c-Tongue blade therapy
d- Maxillary appliance applying labial force

Correct ans is D, but for a single tooth crossbite tongue blade therapy should not be used?

Try to solve this...
Thanks.
