Coz ampicillin can never act against pencillinase producing & regarding my ques. mepridine cann't be ans coz its of codeine group to which he is allergic.

pls answer my ques:

1. if pt is allergic to pencillin& codeine, wat u give before extraction?
a. mepridine 50mg
b. Ibuprofen 400mg
c. aspirin 650mg
d. acetaminophen 600mg

i tried to find this answer i didn't get. still i i will try to search.
2. effect of tricyclic antidepressants with antiadrenergics? do you have options here?

3. if there is insufficient tissue from oral mucosa toclose alveoler cleft, most common method to obtain soft tissue coverage:
a. dermis b. fascia lata c. tongue flap d. teflon protoplast e. freeze dried dura





why not erythromycin.

thanks.[/QUOT

[the stig]

wats horizontal labial angle?and labiodental angle?help

 

[the stig]

here is an mcq from dental deck and i dont get its explaination at all because i think its contradictory..it goes
as compared to type 4 gold alloys ,base metal alloys have
1: greater resistance to deflection(i dont know wat it means)
2:lower yeild strength
3:high modulus of elasticity
4: low sp gvty
can anyone explain...i think 1 2 3 are contradictory...
i need help with my prep of part two exam desperately
thnx

Thank u Endodontia, if person is allergic to codeine then can we give mepridine to him?

Coz ampicillin can never act against pencillinase producing & regarding my ques. mepridine cann't be ans coz its of codeine group to which he is allergic.

Regarding the 1st question. There is a clinical case which asks a ? like this. Pt takes aspirn daily and allergic to Pen and codiene and has gastric problems. Meperidine 50 mg is the answer.

3. if there is insufficient tissue from oral mucosa toclose alveoler cleft, most common method to obtain soft tissue coverage:
a. dermis b. fascia lata c. tongue flap d. teflon protoplast e. freeze dried dura

Ans--- tongue flap

 

[Endodontia]

Yes. That was what I understood from the question. I haven´t looked at pharm yet, but this question and answer came from one of the adsa booklets. Also, I found on the internet..

patients truly allergic to codeine can usually take fentanyl (Sublimaze), methadone, propoxyphene (Darvon), or meperidine, if appropriate. On the other hand, patients truly allergic to codeine should not be prescribed morphine, hydrocodone, oxycodone (Oxycontin, OxyFast, OxyIR, Roxicodone), or hydromorphone (Dilaudid, Palladone).

If I come across anything that contradicts, I will let you know, but for now, Meperidine is correct.

Thank u Endodontia, if person is allergic to codeine then can we give mepridine to him?

Coz ampicillin can never act against pencillinase producing & regarding my ques. mepridine cann't be ans coz its of codeine group to which he is allergic.

Hey ocs1986,
These all r right ans but not sure about if vertical root fracture is also cracked tooth syndrome, as cracked tooth can lead to vertical root fractur
Now is it anatomical structure or apical pathology that remains at same position regardless of cone postion?? pls let me know

I thought it was apical pathology that remains at the same position regardless of cone position and the anatomical structure moves the the change of position. Is this correct????

i have no idea

I know glutaraldehyde is a cross linking agent (choice 1) and it can be used as a desinfect in lower concentrations (choice 4). It has a max effect against viruses and spores if placed in 2% for 10+ hours (eliminating choice 3, which in turn eliminates B and D).
I would go with C, even though I thought it was toxic to tissues???

What do you think guys?

 

[Endodontia]

I just found this article, which clears up my doubt on gluteraldehyde being toxic to pupal tissue so I would go with CHOICE C....

Pulpal tissue changes following pulpotomies with formocresol, glutaraldehyde-calcium hydroxide and glutaraldehyde-zinc oxide eugenol pastes in primary teeth were investigated for a period of 12 months. Compared with the other groups, clinical, radiographic and histologic examinations revealed glutaraldehyde-zinc oxide eugenol combination had a higher success rate.

e. The host's susceptibility Answer

is this question and answer from ASDA papers?

 

[Endodontia]

Benny, where did you find these questions specifically because many of your doubts are mine as well. I don´t think I am going to be much help here to you...

1. most sensitive tissue to radiation induced cancer:a. liver, thyroid, salivary
Here ans explain (asda j) that thyroid is most sensitive for it but in other ques with option female breast too, ans is breast so if it’s a right ans or here also it should be thyroid

I only came across this question which had thyroid as an answer. Where did you find the other one?

2. Agranulocytosis may involve early lesions of oral mucosa & gingival that r non specific but resemble:
a.Gingival hypertrophy b. Necrotizing ulcerative gingivitis c. Non specific vesiculobullous stamatitis
I think a but ans given is b?

I would go with B. Agranulocytosis is an acute condition involving severe leukopenia which can lead to signs of fever, sore throat, etc. ANUG is much more severe than gingival hypertrophy and ANUG and Agranulocytosis are both actue, so that is why I would go with B.

3. cytologic exam may aid in diagonosis of:a. herpes
b. recurrent apthae
c. pemphigus
d. erosive lichen planus
e. carcinoma in situ
it has multiple choices a, c, e why not b, and d?

I don´t know??

4. in x-ray equipment, KV control:a. contrast b. speed of electrons c. penetrating power
Ans say only a, and c but don’t it control speed too?

I agree with you. Maybe there is a word in the queston that we are missing. I would go with contrast because that always seems to be more emphasized, but it also controls speed of electrons...

5. initial incision for gingivectmy is made 1mm from gingival margin coz gingivectomy performed to base of pocket would remove attached gingival.
Ans is neither statement nor reason is correct But if reason is not right?


6. correction of marked prematurity on the periodontally involved tooth result in clinically observed reduction in: a. mobility
b. facial cleft
c. gingival inflammation
d. perio pocket depth
f. all
Ans is a but wy not all?

The question says "correction on periodontic involved teeth" so that eliminates B,C and F. We are now between A and D. I would go with A.

7. 5yr child lost mand 2nd molar, subsequent arch lenth loss noted at 6 and half was mainly caused by: a. growth,b. muscle imbalance, c. force of eruption , d. force of occlusion
if it should be b or c?

I would go with C since early loss of primary teeth can lead to inadequate space..
8. which sement is the easiest to remover after procedure:
Zinc Phosphate is this correct??

Benny, again I am sooo sorry for my horrible answers, but I am only guessing. I do not know the answer for sure. Let me knowhere each of them came from so we can work on them together...

Hi Benny,
I think the answer for this question is6. correction of marked prematurity on the periodontally involved tooth result in clinically observed reduction in: a. mobility
b. facial cleft
c. gingival inflammation
d. perio pocket depth
f. all
Ans is a but wy not all?

The question says "correction on periodontic involved teeth" so that eliminates B,C and F. We are now between A and D. I would go with A.

The answer is A because a premature occlusion is a traumatic occlusion and traumatic occlusion is seen clinically as mobility whereas traumatic occlusion does not affect the gingiva which are related to the remaining options.
Hope I am right

2. Agranulocytosis may involve early lesions of oral mucosa & gingival that r non specific but resemble:
a.Gingival hypertrophy b. Necrotizing ulcerative gingivitis c. Non specific vesiculobullous stamatitis
I think a but ans given is b?

and regarding this question ,in carranza it is given that agranulocytosis is characterized by ulceration and necrosis of gingiva that resembles ANUG.so the answer will be B

7. 5yr child lost mand 2nd molar, subsequent arch lenth loss noted at 6 and half was mainly caused by: a. growth,b. muscle imbalance, c. force of eruption , d. force of occlusion
if it should be b or c?

for this answer i will go with C(force of eruption )because the arch length is reduced when the first permanent molar erupts mesially following the loss of the primary mandibular second molar ,leading to a loss of arch length.

5. initial incision for gingivectmy is made 1mm from gingival margin coz gingivectomy performed to base of pocket would remove attached gingival.
Ans is neither statement nor reason is correct But if reason is not right?

the first statement is false because the initial incision for gingivectomy starts apical to the points marked with a pocket marker ,so the initial incision won't be made 1mm from the gingival margin.
the second statement is false because gingivectomy does not remove attached gingiva.

(b) prominent recipient root
(c) ultra-thin recipient tissue
(d) inadequate amount of keratinized donor tissue

Ans is a, b, d but how b is effective here?

6. Which of the following components or products of aplaque bacteria are antigenic in humans?
(a) enzymes and other proteins
(b) hydrogen sulfide

But how nitroglycrine effect perio t/t?


8. Maintenance care intervals should be more frequent for patients treated by apically positioned flaps than for patients treated by access flaps because plaque forms more rapidly on root surfaces than on crown surfaces.
Both r wrong but if they r not right?

ans is a, b why not c too?

I guess choice c would make the denture loose and not fit at all.It shouldn't make it sore or irritating.
