[Endodontia]

I agree with all of the answers except this one. My answer is A

which of the following is seen MOST frequently among temporomandibular-joint dysfunction patient
a. depression
b. psychosis

Dear dentist 2013 , these are my opinion
any correction plz

 

[Endodontia]

Stannous Flouride causes staining. I read it in the decks...

@ angiematt,

its false ---the amount of epithelial attachement improvement and reduction in pocket depth in mandibular furcations is better than maxillary----studies have proven that and its given in newman

i dont know the flouride one---lemme know if u gt tht answer
i guess it should be stannous flouride......but please do lemme know u get them..

 

[carabelliballin]

1. Why are composites not put in primary teeth? maybe due to enamel rods

2. 6 yr old has ALL, her deciduous molar has a large carious lesion and furcation radiolucency - is the txt a pulpectomy? confused due to the furcation

3. when suturing in oral cavity? is it fixed to movable or is it movable to fixed structure

4. 5 yr old, 1st visit, no problems, all contacts visualized, good OH, according to FDA how many xrays do u take? there ans was None, i thought u would atleast take 2 BWs

5. best aid in diagnose irreversible pulpitis? is it EPT or thermal

6. The most critical primary tooth when lost prematurely? K9 or 2nd molar

7. What cause more wear on enamel? filled resin, unfilled resin, amalgam, enamel

8. placing a thumbsucking device in a patient is considered? - positive, negative or adversive reinforcement

9. what structures need to grow back to show peridontal recovery? Sharpey's fiber and cementum, sharpeys fiber and cementum and gingiva or sharpeys fiber and cementum and alveolar bone

will greatly appreciate ur help guys
Thank you

Hey Marco09, the answer for the centric relation registration is "C". It would cause deflection of mandible..Here is the reason.....read it
http://www3.musc.edu/occlusion/Handouts/11crtechnique.html

Pottasium sulphate is the Gypsum Hardener added to hydrocolloid impression material which accelerate the set of gypsum/ Earlier when pottasium sulphate was nt added to hydrocolloid it lead to porous surface of cast and so they kept it n pottasium sulphate. The residual calcium hemihydrate crystals intiates the reaction...

This is given in Anusavice only under hydrocolloid impresison materials....
Hope it helps,

.The measure of intensity is.
.a. ..half value layer.
.b. ..kVp.
.c. ..mA.
.d. ..mAs.

..
.I'm pretty sure the answer is kVp, but i think i'm confusing myself and thinking it could be mA!!!.
.Please correct me..
.

[blasphy]

@marcoo9
i think the ans for the radiograph q is it will be located in lingual as it moves towards the same side as it was b4 correct me if i am wrong
@jackson
it is definitely kvp as it is the only one which affects the intensity

Can u put forth ur reasoning...and please share ur thoughts

hi dentist 2013 you are so kind thanks for your time

for me it is lung stretch cause if you have low CO2 you will breath faster 9so there is no depresion of respiration).in the other hand the stretching of the lungs will activate the hearing-bauer reflex so they will induce a depression in respiration.

and in inflamation you will see an increase in blood vessels (i mean the gauge) just to more blood with all the forming elements arrive to the site of inflammation.

 

[marco09]

hi dentist 2013 you are so kind thanks for your time

tempered is when you put the modeling compound to take the primary impresions to get the custom tray

A. buccal to the premolars.
B. lingual to the premolars.
C. on the same plane as the premolars.
D. mesial to the premolars.
E. distal to the premolars my ans e


They say only the direction of the movement of the object and not the tube. We all know that we should apply the SLOB rule = same lingual opposite buccal --- but then again, how would you know if they aimed more mesially or more distally the xray tube when the second shot was taken? just wondering...


Any ideas? Anyone?

@marcoo9
i think the ans for the radiograph q is it will be located in lingual as it moves towards the same side as it was b4 correct me if i am wrong
@jackson
it is definitely kvp as it is the only one which affects the intensity

 

[bombshell]

Here's my input of all the questions I will give the reasons for each under every question

Hi Freinds , I have some different Idea in these questions

The redness of an inflammatory lesion of oral mucosa is due to
A. increased number of capillaries.
B. increased size of capillaries. ==may be it is due to vasodilattion
C. decreased thickness of epithelium.
D. decreased connective tissue elements.
E. All of the above Yes this is the answer: Why? Well, in inflamation we have the redness (in latin rubor) which is dur to vasodilatation (yes, so B is correct) but also in late stages there is proliferation of new capillaries (answer A should also count in). So A and B all together makes E to be the best option. Correct me if I am wrong

An early radiographic sign of chronic periodontitis is
A. widening of vascular canals.
B. "notching" of the crestal lamina dura. - RIGHT ANSWER
C. enlargement of the interdental medullary spaces.
D. decreased radiolucency of the interdental trabeculae
I have to go with B, here! The first changes are seen on the "top" of the crests of lamina dura. An early sign is that they are basically "foggy". You can't see decreased Radiolucency (RL) of interdental trabeculae early on (It needs like 3-6months to manifestate and also the finding may or may not be taken in account as it will be suddle). So I am really sure it's 100% B!

To improve denture stability, mandibular molar teeth should normally be placed
A. over the crest of the mandibular ridge.
B. buccal to the crest of the mandibular ridge.
C. over the buccal shelf area.
D. lingual to the crest of the mandibular ridge.
There are different schools of how to place teeth when making a denture. For the one that I have been taught in dental school states that the teeth should be over the crest of the mand. ridge for stability reasons, though in reality you will place the teeth maybe lingual to the crest if the resorption is severe (you need to make the teeth occlude in the end, right?) So I am really puzzled by this questions. Is it A or D?! Anyone?

For complete dentures, the most critical factor affecting speech is the
A. reproduction of rugae.
B. positioning of molar teeth.
C. positioning of anterior teeth.
D. palatal thickness

Answer
Actually Mosby says that they are all factors that affect the speech, but I think that somewhere in the decks there was this prostho question and they had picked Palatal Thickness for the correct answer. As I come to think about the question, if you have a very thick denture, your palatal vault with it will be decreased, making the voicebox smaller, hence why your voice will change significantly. So I think D is the best answer.

Good luck to everyone! And please, correct me if you think otherwise!

 

[persiandentist]

THank you very much bombshell for your clear explanation , that was helpful ,
best wishes

 

[blasphy]

yes u r right bombshell assuming in the question that distal is MOVING AWAY although they dont mention it i think there is some correction needed in the q itself
thanx for the clarification input

 

[bombshell]

Right! The question itself doesn't have all the necessary information and that's why it makes us go nuts trying to figure it out. Good luck to all of us!

Wrought iron is an iron alloy with a very low carbon content, in comparison to steel, and has fibrous inclusions, known as slag. This is what gives it a "grain" resembling wood, which is visible when it is etched or bent to the point of failureWrought iron is tough, malleable, ductile and easily welded.

I got this from Wiki...Well B is out and so D is out. I would go between A and C.
If you think about it though...A makes more sense to me. Bc you're basically working the metal and elongating it. NOT sure!

.1.R..esorption of bone takes place in which direction after extraction..:.
.Downward, inward.
.D..ownward..,.. outward,
..D..orward..,.. inward

..Downward and inward ..is the test answer...i can't find this anywhere...
.Any one have and idea...

.2.Which of the following is not a property of gutta-percha . .
.radiopacity, .
.Biocompatibility, .
.Antibacterial.
.Adaptation.
. .
.The test answer is adaptation…but I found in my searches that it is actually pretty adaptable!!! .
. .
.3. you have too much incisal overlap…what do you need to change to maintain balanced occlusion?.
.Increase condylar inclination -------> test answer is this but why?
.
.Decrease condylar inclination.


Thanks for the help guys!

.2.Which of the following is not a property of gutta-percha . .
.radiopacity, .
.Biocompatibility, .
.Antibacterial.
.Adaptation.

The ans is Antibacterial.

 

[twinklestar123]

To increase contrast the operator should
a.Increase kVp
b.Decrease kVp
c.Increase mA
d.Decrease mA

 

[twinklestar123]

Which of the following is most commonly used to correct maxillary retrognathia?
Le Fort 1
C-osteotomy
anterior maxillary osteotomy
C osteotomy

 

[dentist2013]

To increase contrast the operator should
a.Increase kVp
b.Decrease kVp
c.Increase mA
d.Decrease mA

Answer is decrease KVp. Because it decreases the energy of the beam and thus the penetrability ==which helps in producing high contrast/short scale contrast.

Which of the following is most commonly used to correct maxillary retrognathia?
Le Fort 1
C-osteotomy
anterior maxillary osteotomy
C osteotomy

answer is Le Fort I=== it helps in anterior and downward displacement of maxilla


Which of the following is not a property of gutta-percha .
radiopacity,
Biocompatibility,
Antibacterial
Adaptation

I think the sealing agents are used to improve the adapatability and sealing of root canals so they are least adaptability...Not sure though

hi mr jacksone hope my answers will help

 

[twinklestar123]

Hi! guys,
how's everyone doing? and how's studies going on?I started with oral path today.Hope to be done with it in 3 - 4 days.

 

[marco09]

hi guys what happens does everybody is alive!!!!!!!!!!!

well hope you can help me with my qc

anyways i have this qc

Which thermal property is most important in selecting a restorative material to protect the pulp from excessive temperature changes?
A. conductivity.
B. diffusivity.
C. expansion coefficient.
D. modulus.

for me it's a (but i doubt c because of percolation ???can anybody help me please

 

[perfectionist1]

Hey...
Can anybody tell me what happens to vertical dimension when we move from rest position to centric relation?

 

[twinklestar123]

I tried searching the answer to this.But i am getting confused and couldn't get the answer.Are you asking about the vertical dimension at rest or occlusion? May be occlusion...I think it increases not sure thou.

Hey...

[perfectionist1]

I tried searching the answer to this.But i am getting confused and couldn't get the answer.Are you asking about the vertical dimension at rest or occlusion? May be occlusion...I think it increases not sure thou.

I meant VD at occlusion only...since we are considering maximum intercuspal position....not getting a confirmed answer....

 

[twinklestar123]

The Vertical dimention of occlusion increases.

 

[perfectionist1]

The Vertical dimention of occlusion increases.

Thank you

 

[marco09]

Thank you

guys let me give you an advice CR is a ligament guided position so tooth contact shold not interfere (so we should reformulate the qc if the DVO increases or decreses in and premature or deflective depending how much distance between from rc ti MIC in the contact in RC). if there is a prematurity the DVO increases reducing the freeway space .

hope this clud help
