The cells within the epithelium are seperated apart from eachother, causing a spacing or cleft between them rather than being attached together in a health person.

Hi All of you!

I have my part 2 in 2 weeks. It took me 3 months to study everything ONLY ONCE! I have done 5 sets of ASDA papers only. I am Very slow at studying and its taking me forever to revise what i studied. So far I have only been able to do Endo perio and oral surgery and still have ALL the rest left!

I am freaking out now as there is NO way Ill be able to revise everything in just 2 weeks. Please give me some tips on what to revise in the last 2 weeks. I also feel I have major attention deficit and cant focus on a topic for more then 2 hours... Please help! I am VERY worried!!!

Thanks in advance

B and EXCESSIVE ridge resorbtion. If this is choose the best then I would pick B ( centric occlusion CR donot coincide. If you can choose more then one then b and c.

thanks for the quick reply. this really helps.
Just wondering why did you choose c? I was thinking residual ridge resorption is one of the indication for relining complete dentures.
since option does not say EXCESSIVE ridge resorption, only b should be ans. Am I right?

Hello ppl

can anyone answer these questions plz?

single rooted anterior teeth has endodontic treatment is best treated by:
- casted post and core
- preformed post and composite
- preformed post and amalgam
- composite post and core

one of the anatomical landmarks is:
- ala tragus line
- ala orbital
- frank fort plane
Click to expand...
A pub med article along with my notes from Pros at Iowa suggest that the cast post and core provides the best clinical outcomes.

I think the answer for it is veracity as he is not telling the truth to patient! he voilating veracity as amalgum is not a harmful substance!

perio exam

1. Attached gingiva :
A. Declines with age - in upper PM area because of narrow vestibulum
B. Increases with age - lower incisors lingual side because it is the highest area
C. Declines with age - in the lower PM area , in the vestibule where it is narrowest.
D. Increases with age - molar region is the most high-lingual side

2 Collagen fibers comprise what percentage connective tissue?
A. 60
B. 70
C. 45
D. 50


3. Adding ultrasonic water:
A. Cooling device
B. Constant rinsing
C. lowers the intensity of the device does not cause tooth surface roughness
D. All true


4. What is true with regard to established lesion?
A. Increase in plasma cells, and the beginning of epithelial proliferation of JE, and creation of rete ridges.
B. Increase in plasma cells, and the Continuation of epithelial proliferation of JE, and creation of rete ridges
C. decrease in plasma cells to get to advanced lesion .

5. What is true for Aggregatibacter actinomycetemcomitans, and Tannerella forsythia?
A. AA is uniquely anaerobic obligatory and therefore not sensitive to metronidazole.
B. For TF (tannerella), there is a Bspa that is stuck to the pellicle.
Bspa is Leucine-Rich Repeat BspA Protein


(A is false because AA is facultative anerobic; TF I do not know about BspA protein. It is not mentioned online).


6. Which bone resorption is the hardest to identify on X-ray?
A. Circumferential
B. 3 wall pocket
C. Periapical periodontitis

(my answer B)

7. What is true of junctional epthelim ?
A. Larger cells than oral epithelum
B. Coronal portion has 10-15 cells
C. Connected to tooth by Hemidesmosomes
D. All true


CARANZZA SAYS P23
The junctional epithelium
consists of a collarlike band of stratified squamous
nonkeratinizing epithelium. It is three to four layers thick
in early life, but the number of layers increases with age
to 10 or even 20 layers. These cells can be grouped in two
strata: basal and suprabasal. The length of the junctional
epithelium ranges from 0.25 to 1.35 mm.
The junctional epithelium is formed


8. What appears the histology of healthy gums?
A. Filtrate of neutrophils in epithelium and lymphocytes in connective tissue
B. Filtrate of neutrophils in epithelium and Macrophages in connective tissue
C. Lymphocytes in epithelium
D. Neutrophils around capillaries in connective tissue.

C. Declines with age - in the lower PM area , in the vestibule where it is narrowest.
D. Increases with age - molar region is the most high-lingual side

First..Attached gingiva declines with age factors include eating and upward movement of tooth.
second-->upper PM anatomy is strong than lower PMs..
Let me know if i am correct?


2 Collagen fibers comprise what percentage connective tissue?
A. 60
B. 70
C. 45
D. 50

i think its 60..
first--collagen fibers are mostly proteins.
secondly --70 is too much protein..

3. Adding ultrasonic water:
A. Cooling device--this is the second function
B. Constant rinsing---this is what it does mostly so its primary function of adding water
C. lowers the intensity of the device does not cause tooth surface roughness--there is no connection in roughness and water
D. All true


4. What is true with regard to established lesion?
A. Increase in plasma cells, and the beginning of epithelial proliferation of JE, and creation of rete ridges.
B. Increase in plasma cells, and the Continuation of epithelial proliferation of JE, and creation of rete ridges
C. decrease in plasma cells to get to advanced lesion .
PC suppose to increase to fight the infection and inflammation
secondly--lesion is just established..so beginning of epi proliferation and
creation of new cells

5. What is true for Aggregatibacter actinomycetemcomitans, and Tannerella forsythia?
A. AA is uniquely anaerobic obligatory and therefore not sensitive to metronidazole.
B. For TF (tannerella), there is a Bspa that is stuck to the pellicle.
