all associated with gastric limitation except
1)alcohol
2)indomethacin
3)ibuprofen

Since indometacin inhibits both COX-1 and COX-2, it inhibits the production of prostaglandins in the stomach and intestines which maintain the mucous lining of the gastrointestinal tract. Indometacin, therefore, like other nonselective COX inhibitors, can cause peptic ulcers

Ibuprofen appears to have the lowest incidence of gastrointestinal adverse drug reactions (ADRs) of all the non-selective NSAIDs. However, this only holds true at lower doses of ibuprofen, so over-the-counter preparations of ibuprofen are generally labelled to advise a maximum daily dose of 1,200 mg.


Alcohol on the other hand can cause acute pancreatitis and liver inflammation ....so this question is super weird

i think its a close btn ibuprofen and alcohol and ..
ibuprofen wins hands down.

Aspirin is a non selective COX inhibitor.The analgesic action is MAINLY due to obtunding of peripheral pain receptors and prevention of PG mediated sensitisation of Nerve endings...

Pentobarbital has no analgesic actions... Barbiturates do not have anlagesic action adn even small doses mght cause hyperalgesia.

Aspirin's ability to suppress the production of prostaglandins and thromboxanes is due to its non-competitive and irreversible inhibition of the cyclooxygenase (COX) enzyme. Cyclooxygenase is required for prostaglandin and thromboxane synthesis. Aspirin acts as an acetylating agent where an acetyl group is covalently attached to a serine residue in the active site of the COX enzyme. This makes aspirin different from other NSAIDs (such as diclofenac and ibuprofen), which are reversible inhibitors.

Prostaglandins are local hormones (paracrine) produced in the body and have diverse effects in the body, including but not limited to transmission of pain information to the brain, modulation of the hypothalamic thermostat, and inflammation. Thromboxanes are responsible for the aggregation of platelets that form blood clots. Heart attacks are primarily caused by blood clots, and their reduction with the introduction of small amounts of aspirin has been seen to be an effective medical intervention. The side-effect of this is that the ability of the blood in general to clot is reduced, and excessive bleeding may result from the use of aspirin.

Central and peripheral activities The analgesic and antipyretic effects of aspirin are CNS effects, whereas the anti-inflammatory and anti-rheumatic effects occur in the periphery.

Separately labelled acetyl and salicylic moieties of aspirin build up in different parts of the body. The acetyl group is a strong prostaglandin inhibitor and acts peripherally, while salicylic acid, a weak prostaglandin inhibitor, is able to cross the blood-brain barrier and act centrally in the spinal cord.

so the answer is either 1 or3 so help me out here
 
thanks... but its saying or asking trauma from occlusion, didnt mention about if the load is not along the long axis of the tooth.

gingival inflammation is the correct answer bec. plaque is the primary cause for gingival infammatio .beside that trruma never cause gingival inflamation,it causes tooth mobility,wear,widening of pdl,hypercementosis
 
in constructing upper complete denture against lower natural dentition .when we do the occlusal adjustment
A.during try appointment
B.after constructing study cast and treatment plan
C.during delivery of denture
D.after the final cast

i think its an A ...cuz u dont want to copy deflective occlusal contacts in the new prosthesis not sure though

I disagree. The only answer that even makes sense is B.

If you're doing an occlusal adjustment on the remaining natural teeth, you would want the opposing cast to reflect the teeth *after* you've adjusted them, not before.

A, C, & D require taking your master impressions before you've adjusted the teeth, which means your models aren't representative of the patient, which means you'll be making your denture to fit their mouth as it existed *prior* to your occlusal adjustments.

B is the only option that puts events in the proper sequence: diagnosis (i.e., this is where you recognize the adjustment will be necessary), occlusal adjustments (to improve occlusion against the denture), master impressions (so you can make the denture to fit against the teeth as you've adjusted them, not as they were beforehand).

Veneer What Do You Use To Clean It After You Try It On ?
Ethanol
Hydrochloric Acid
Pumice
Phosphoric Acid

Back of Veneer, when they came from lab hase been etched and precondition with silane to improve the bonding property with tooth surface, when you do try in, this surface may contaminated by your hand and oil based residue will stick on these precondition surface, to removed is simply wash the oil dirt with ethanol or alcohol. Pumice is used for polishing, you may take off all the silane apply on the back of veneer - and you need to precondition the surface again. Hydrchloric acid is a very strong and volatile acid that you probably will not find it on your clinic. Phosphorc acid is too weak for etching the veneer surface for cementing, however it used to etch tooth surface prior cementing.
For etching veneer, the best acid is HF - Hydro Fluoride acid - that what the lab use to do prior precondition it with silane.
I wish this will help.
