correct me if iam wrong

Regarding #8.

-comparison of elastomerics:
-setting time: polysulfides > silicones > polyethers
-tear strength: polysulfides > silicones > polyethers
-stiffness: polyethers > silicones > polysulfides
-permanent deformation: polysulfide > polyether > silicone
-dimensional change: condensation silicone> polysulfide > polyether > addition silicone

 

[LaValencia]

Is it specified in Malamed??

Yes. Page 58 and 59 of 5th edition

 

[LaValencia]

it is supposed be to be eye movement,the titration is checked while watching the patients eye movement,verbal response does not make any sense??????

Is the question referring to general anesthesia which is the elimination of all sensation, accompanied by loss of consciousness? Or, Concsious sedation?

There are four stages of general anesthesia.
Stage I: analgesia: A deadening or absence of the sense of pain without loss of consciousness. During phase I, pat. response to command determines loss of pain. Eye movement is normal.

anesthesia: insensibility to pain with or without the loss of consciousness

If you are monitoring stage II (delirium), III (surgical anesthesia), observe the following:
1. character of respirations
2. Eyeball activity
3. pupillary changes
4. eyelid reflex
5. swallowing or vomiting.
6. respiratory response to skin incicsion
7. secretion of tears
8. assessment of pharyngeal and laryngeal reflexes

Ref: Sedation, 4th edition, Malamed

[akka]

Is condensation silicone same as PVS? or is addition silicone that is same as PVS? thanks

 

[akka]

hey guys, can u answer these qs for me? my exam is tomorrow. anyone else taking it tomorrow or today?

1)to cut md tori do we use envelope flap?

2)for hemophilia di we check pt or ptt?

3)for warfarin according to kaplan and oldexams says to check PT, but isnt it
INR?

4)carbocaine 3%, kid weighs 55lbs, how many carpules can u give? 2.5?

5)when apices are complete, how to treat mx incisor fractured tooth due to trauma?

4)with intruded tooth,most likely to have pulp necrosis or internal resorption?
on one old exam it said externl resorption but i think thats a mistake?

5)avulsed tooth replanted-likely to have pulp necrosis and ankylosis?

 

[AbstractDentist]

For hemophilia check PTT - it is prolonged PT is normal

Warfarin and other anticaogulants - INR

When apices are complete - do RCT

Addition Silicone - polyvinyl siloxane

Carbocaine - my guess is about to 2 cartridges/carpules

 

[RocknSun]

foundation for much of risk management is ?

What reason not to have to replace class II amalgam?
Open contact packing food,
fracture at axiopulpal line angle area,
recurrent decay radiographically,
occlusal margins over carved

it has to be open contact point...reason area will be soon ward off by migration of adjacent tooth.

 

[AbstractDentist]

i think the question is asking reason for not replacing the restoration.
all other reasons except for over carving needs to restored.

 

[RocknSun]

thanks and wishing u too good luck


ans is occlusal margins over carved

IS IT NOT "B"

-Difference between Osteosarcoma & fibrous dysplasia is that osteosarcoma
A- can invade soft tissue. B- is an ill-defined radiolucency. C- is Malignant. D- difficult to irradiate(?) from normal bone.
IS IT NOT 1,2 3????

A protective mechanism of the dental pulp to external irritation or caries is the formation of

A. pulp stones. *
B. secondary dentin.
C. secondary cementum.
D. primary dentin.
A .....B?????

 

[highbrow]

causes of composite polymerization shrinkage during setting
1-Evaporation of the by-product.
2-Evaporation of unreacted monomer.
3-temp change occurring during polymerization.
4-replacment of 1ry bonds by 2ry bonds*



2 OR 4????????????

 

[highbrow]

guys no one`s coming forward to confirm the answers...plz help

 

[momdent06]

i think its 2.

ans. is 4

 

[RocknSun]

A. pulp stones. *
B. secondary dentin.
C. secondary cementum.
D. primary dentin.
A .....B?????

and for the second its

evaporation of unreacted monomer

 

[ExxonMobil]

Can anyone answer this question:

Best prognosis for implants in order:???????????????????????
-man. post
-mand. Post
-max. ant
-max. post

 

[RocknSun]

when guttapercha is heated the transition from phase to beta phase occur at

115f
125f
135f
145f
155f

[failure of soft tissue liners is mainly due to

1 water sorption
2 loss of plastisizer
3 loss of its strenght
4 lack of adhesion to the denture
5 improper mixing of powder and liquid component

foundation for much of risk management is ?

1)loss identification
2)loss analysis
3)loss avoidance
4)loss without fault
5)loss financing

when guttapercha is heated the transition from phase to beta phase occur at

115f
125f
135f
145f
155f

pt with G 6 PDdeficiency often have increased sensitivity to

cyclosporin
rifampicin
chloramphenicol
augmentin
amphotericin-b

each of the following nerve is anesthetized in allmost all the pt when gow -gates mandibular nerve block is given? except

lingual nerve
mental nerve
acuriculotemporal
mylohyoid
buccal

 

[linu]

ans. is 4

I think the answer for this question is 2.The shrinkage is due to evaporation of monomer

 

[dent_mangalore]

success of implant:
mandible>maxillary anterior>maxilary posterior

IS`NT GENETIC N EPIGENETIC A FACTOR??????THE CHOICES WERE...1,2,3 ....OR 2,4....OR 1,3 .....OR ALL..

according to Van Limborgh's Theory-genetic factors,epigenetic factors and environmental factors are responsible.
