Q)Class 3 patient at 14 as grows which decreases
anb
snb

A: ANB

Q)Hepatitis contagious
surface antigen pos
surface antigen negative
surface antibody pos
surface antibody neg

A: surface antigen positive

Q)what would make the solder joint of a fpd strong
wider occlusal gingival
wider buccal lingual

A: wider buccolingual
So it wont interfere with occlusion and proper cleaning of fpd

Q)when do u make the custom tray for pfm crown
after impression
b4 impression
after prep
b4 prep

A: before final impression is made



all correct except

3.Soldering joint Increases in strength when wider occluso -gingival{it is stroger when its height is increased }


smiley is right :) its on the deck
 
a test result failed to indentify 5 cases of true disease . what will this be

false positive
false negative
positive predictive value
negative predictive value

vertical root fractures are also called cracked teeth .prognosis of cracked teeth varies with extent and depth of the crack ?

first statement is true second false
firt false second true
both true
both false
 
a test result failed to indentify 5 cases of true disease . what will this be

false positive
false negative
false predictive value
negative predictive value



The negative predictive value is the proportion of patients with negative test results who are correctly diagnosed so thats incorrect

false positive is also incorrect as they are all dignosed to be healthy.

false predictive no idea what the heck that is

false negative is the answer btw as all people were not healthy but were incorrectly diagnosed to be.
 
vertical root fractures are also called cracked teeth .prognosis of cracked teeth varies with extent and depth of the crack ?

first statement is true second false
firt false second true
both true
both false


both statements are true the prognosis depends on the extent duration and location of the fracture.
 
which of the following describes the character of dentinal tubules at the pulpal end as compared to the enamel end

more per unit surface area and more wider in diameter
less per unit surface area and more wider in diameter
more per unit surface area and smaller in diameter
less per uint surface area and smaller in diameter

more per unit surface area and more wider in diameter
less per unit surface area and more wider in diameter
more per unit surface area and smaller in diameter
less per uint surface area and smaller in diameter

thats a mean question :/ heh wider in diameter i THINK as the whole hydrodynamic fluid theory crap and less per unit area as the pulp is surrounded by a single layer of odontoblasts predine etc etc CORRECT me i am wrong i hate this question!

It's mean to expect a dentist to know something about basic dental histology?
 
i guess noones interested good luck everyone i have my exam in just one week inshAllah tc all

1.To ensure better thermal and protective insulation of the pulp during a capping procedure, calcium
hydroxide should be:

A. Applied to a thickness of 3.0 mm.
B. Placed in all cavity preparations.
C. Covered with a stronger base.
D. Preceded by application of a cavity varnish.

much better! yeah i had a feeling the last one was fever. so infection could mean viral or bacterial right? would you have a fever with both? or just bacterial?

wait, so why not lymphadenopathy?
 
1 . A maxillary first molar is extruded 4 mm into the opposing space of a missing mandibular first molar.
To restore this you would
a) restore the maxillary molar with a crown before constructing fixed partial denture in the lower arch
b) extract maxillary molar and restore both with fixed partial dentures
c) do occlusal grinding of maxillary molar to adjust occlusal plain
6) construct removable partial denture

option a is incorrect CHECKED from the prosthodontics decks.you restore the max molar AFTER restoring the edentulous mandibular molar.b is incorrect as well.now we are left with c and d. so ummmmm

and yeah NEUTROPHILS are predominant in the crevicular fluid.

Who says B is wrong? It's the best answer out of the four.

(the best solution, assuming the patient is a suitable candidate, is to extract the upper molar and replace with an implant to restore the patient's original occlusal plane)

following is indicated?

A. Incision and drainage
B. Nonsurgical retreatment
C. Re-evaluation in six months
D. Apicoectomy and apical amalgam

nopes ur very right :)
 
Someone could help me with this, please.


When it says say that it is needed to give 0.25 or 0.50 or 1.0 of flourode ion suplementation , this means that you have to give how many miligrams of NaFl?

This is driving me crazy!!!!

Please, help!

2.2 mg of Naf will provide 1 mg of flouride.its a standard memorize it been calculated according to the atomic weight of both sodium and flouride.
 
20. What is the clinical ‘hallmark’ of a chronic periradicular abscess?
a. Large periradicular lesion ....correct
b. Sinus tract drainage
c. Granulation tissue in the periapex.
d. Cyst formation.

this ans should be sinus tract as chronic periradicular abcess

large periradicular lesion , is not a clinical but a radiographic hallmark

as per the notes .pls confirm
