U r correct , I u think most accepted theory is hydrondynamic one
-Which of the following is/are common to both gingival and periodontal pockets?
D gingivitis doesn't have apical migration and peridontitis doesn't have fibrotic enlargement of tissue plus bleeding is not a sign of periodontitis.You may have bleeding in perio, I agree most appropriate ans is D in this question
-The use of an etchant and bonding system before insertion of a composite resin restoration results in?
not so sure!!
Please check dental decks operative card 54 and also card 108 for sensitivity
also this link may be usefull http://www.dent.ohio-state.edu/cours...es%20notes.pdf

I am also confused about Q with composite may it be E according to DD?

1.A Why not B - Leukocytosis
2.A
3.C
4.A reference plz http://www.dent.ucla.edu/pic/members...ion/index.html
As I understand it LA can elevate BP due to epi while GA lowers it .I cardiac patients the LA is better but it si not the question.
if u have more relevant ref please share.

Why not B - Leukocytosis
Yes B. Leukocytosis is correct. Lymphocytosis is mostly seen with viral infections. Acte bacterial will be neutrophilic leukocytosis. So in this case the answer is B. Lekocytosis!

2.A
3.C
4.A reference plz
I am aware of the untoward effects of LA on myocardium...but when contrasted with general anesthetics, I am not sure which is more. Goodman and Gilman:
General anesthetic = The most prominent physiological effect of anesthesia induction, associated with the majority of both intravenous and inhalational agents, is a decrease in systemic arterial blood pressure. The causes include direct vasodilation, myocardial
depression or both, a blunting of baroreceptor control, and a generalized decrease in central sympathetic tone.

Local Anesthetics = Following systemic absorption, local anesthetics act on the cardiovascular system. Most local anesthetics cause arteriolar dilation.
Since the question does not speak about the use of vasoconstrictors or if LA is systemically absorbed, I would think the answer is B.
Do share any refs or reasoning for A.

5.B
Do they have a broader spectrum than penicillin>???

6.A
7.E
8.B Any refs?? this is unclear to me!
plz confirm

Do check my previous post...true LA WIT Epi can raise BP, but the question does not talk about LA with vasoconstrictors...

3. D
Confused between A and D. Will pick A. Free nerve endings as of now. open tubules...odontoblastic process stimlated within the tubule...transmits pressure to free nerve endings...
The reference that DMDVictoria has given though suggests answer is D...any more contributions??

4. A
Does anyone know the reasoning??

5. B

2. B Why not A - mA and filtration
Filtration will remove the unwanted low energy xray photons from the beam, thereby improving QUALITY. Qantity of radiation output will be related to time...moe time more photons!

3. A
4. E
5. E
I know B is correct. The rest are probably features of periodontitis. Any comments here?? As i remember right ... this was a controversial question as A and B options contradict each other...
true...but the options are different...A says barrier to bacteria themselves,,,which is true...while it is permeable to their products!
6. A Any ref. for air abrasion improving sealant retention.. i only read about etching ...
I think I read about this in sturdevant or decks...you should find it there...
My ans - Pg 6
