Which of the following Antibiotics has been implicated in the vast majority of cases of oral contraceptive failure during antibiotic use?

A. Penicillin
B. Rifampin
C. Keflex
D. Erythromycin
E. Tetracycline

Erythromycin? (from a book)
Rifampin? (from old test)

I'm confused..!!

Neither . Answer should be penicillin - due to suppression of normal GI flora involved in recycling of active steroids from bile conjugates,leading to more rapid excretion of steroids from body.

THIS IS GONNA HELP YOU A LOT...!!!

Thanks Joansete, I tried those questions and its from here only this question.

 

[Joansete]

Somebody knows the difference between External & Internal Hex Implants?
One of my friends told me that was one of the questions on her last month exam...

 

[Joansete]

Your patient exhibits the partially edentulous arch from tooth #21 through 29 remaining. Tooth #29 is tilted mesially. The undercut is on the mesiofacial surface. What would be the best clasp assembly for this situation?

1) Distal rest and cast circumferential clasp.
2) Distal rest and WW circumferential clasp.
3) Mesial rest and I-bar.
4) Distal rest and I-bar.

I would go for Mesial rest and I Bar.
(I bar is when the undercut is on mesiofacial)
(T bar is when the undercut is distofacial)
(I bar can be used on Lingual in Mandibular Molars too)

Correct me if I'm wrong please..!!

 

[Joansete]

Neither . Answer should be penicillin - due to suppression of normal GI flora involved in recycling of active steroids from bile conjugates,leading to more rapid excretion of steroids from body.

THANKS AGAIN (BTW my exam is on 1st and 2nd) :0)

1 Decrease in which of the following causes increase in radigraphic density?
a. mA
b. Kvp
c. object film distance
d. source film distance************
e. exposure time

2 an unconscious patient suspected of having obstracted airway. Management for patient
a. protrude the tongue, clear the pharynx,extend the neck & protrude the mandible.
b. ext. the neck, clear the pharx,prodrude the tong & m/d
c. ext. the neck, protrude the m/d & tongue, clear the pharynx
d. clear the pharynx, extend the neck, protrude the m/d & tongue*************

3. Charecter & individuality of teethare determined by
a. transleucency
b. surface texture
c. color
d. shape********************

4 Which explain why the properly desined rest on the lingual surface of canine is prefered over incisal surface
a. enamel is thicker on lingual surface
b. less leverage is exerted againest the tooth by the lingual rest********************

5 compression of acrylic into denture flask, placing the flask into processing tank at curing temprature is delayed to
a. assure complete flow of acrylic into mold
b. allow monomer to penetrate all polymer***********************
c. establise an equalized & uniform pressure on the mold
d. allow the flask &acrylic to reach at stable tem.

2 an unconscious patient suspected of having obstracted airway. Management for patient
a. protrude the tongue, clear the pharynx,extend the neck & protrude the mandible.
b. ext. the neck, clear the pharx,prodrude the tong & m/d
c. ext. the neck, protrude the m/d & tongue, clear the pharynx
d. clear the pharynx, extend the neck, protrude the m/d & tongue


Shouldn't that be option c? I mean , the first step of CPR would be head-chin-tilt = extend the neck . And the next steps seems logical - to visualize pharynx, you would need to open the patients' mouth and quite possibly move the tongue out of the way. Please do correct me if i'm wrong - I would appreciate it .

(original question posted by myvr, answer dr.ndc)

I agree - this question makes no mention of a spinal injury - so I will go with c.

 

[Joansete]

I agree - this question makes no mention of a spinal injury - so I will go with c.

D it was an answer from an old test, but I agree with you, I'll go for C too...
that's why I put this one...thanks

[meridith]

1. the role of microbial plaque is most obscure in which of the following:
a. desequamative gingivitis.
b. Necrotizing ulcerative gingivitis.
c. Juvunile period.

desquamative gingivitis - because the term is based on clinical picture only and true diagnosis requires further investigation

2. If patient is able to prevent plaque accumulation on his teeth, prophy treatment recommended every?
a. never
b. 3 months.
c. 6 months.
d. every year.

Routine examination is recommended every year, and I've heard hygenists recommend prophy every 6 months . but literature says - no definite conclusions. Viewing from a financial standpoint only - 6 months , otherwise 1 year?

3. in what age necrotizing ulcerative gingivitis most commonly occur? does it occur in Children? before or after puberty?

16-30 years

4. correction of prematurity in periodontally involved tooth results in a clinically observable reduction in:
a. mobility.
b. ginig inflammation.
c. perio pocket depth.

someone explain the meaning of prematurity?
Where did you get this from?

5. Tobacco smoking is thought to be predisposing factor in:
a. juvunile period.
b. gingivitis- periodontitis.
c. necrotizing ulcerative ginig.

option b and c most definitely has tobacco as a predisposing factor .( doesn't cause it, but definitely sets the stage) . Is the question NOT thought to be a predisposing factor? In which case this question makes sense.

please someone explain the reason with the answer?

6. what are the disadv. of temp intracoronal splinting? does it interfere with mastication? can somebody refrere me to a place where can I find an explanation to intra and extracoronal splinting?
I would imagine the disadvantage would be loss of tooth structure and a possible need for restoration/enameloplasty once the the purpose of splint is no longer equired.

7. a patient who has had a radiation tr of head and neck, require RCT, what side effects may complicate the treatment?

a. mental depression.
b. decrease clotting time.
c. muscle fibrosis and limitation in mouth opening.
d. increase chance of infection of oral tissue.

1. a,b,c
2. b,c, d.
3. b, c only.
4. b, d only.
5. a,c, d.

option 5 - a,c,d. Picked d because of osteoradionecrosis, c - because of radiation induced musculoskeletal issues , a - because I can't think of a reason to pick decreased clotting time over depression.

8. adverse pupal reaction is more likely to occur when which of the following materials is placed directly into a deep cavity?
a. amalgum.
b. composite resin.
c. calcium hydroxide.
d. ZOE.

amalgam - conductivity issues .

9. which cell would be the most prominent in initial gingivitis an in established gingivitis?

gingivitis = inflammation of gingiva . So acute - mostly neutrophils , chronic - macrophages and lymphocytes


Please correct me (quickly,please ; test - very soon ) if I am wrong

 

[Denty8833]

THANKS for the answers .. when is your exam??

1. the role of microbial plaque is most obscure in which of the following:
a. desequamative gingivitis.
b. Necrotizing ulcerative gingivitis.
c. Juvunile period.

desquamative gingivitis - because the term is based on clinical picture only and true diagnosis requires further investigation

what about Juvunile period??? because it can occur even if there is no plaque at all as in genetic and Necrophile disorders

2. If patient is able to prevent plaque accumulation on his teeth, prophy treatment recommended every?
a. never
b. 3 months.
c. 6 months.
d. every year.

Routine examination is recommended every year, and I've heard hygenists recommend prophy every 6 months . but literature says - no definite conclusions. Viewing from a financial standpoint only - 6 months , otherwise 1 year?

I agree with you because we all know about the 6 months recall !! but the answer is NEVER !!

3. in what age necrotizing ulcerative gingivitis most commonly occur? does it occur in Children? before or after puberty?

16-30 years
it means that children will not have it ?? and it is only after puberty?

4. correction of prematurity in periodontally involved tooth results in a clinically observable reduction in:
a. mobility.
b. ginig inflammation.
c. perio pocket depth.

someone explain the meaning of prematurity?
Where did you get this from?
it is from old exams !! ASDA papers and the answer is a. mobility

5. Tobacco smoking is thought to be predisposing factor in:
a. juvunile period.
b. gingivitis- periodontitis.
c. necrotizing ulcerative ginig.

option b and c most definitely has tobacco as a predisposing factor .( doesn't cause it, but definitely sets the stage) . Is the question NOT thought to be a predisposing factor? In which case this question makes sense.

well I was thinking the same, I read in mosby that smoking is one of the predisposing factors for gin and perio ... but the answer is c.NUG !! dont know why ?
please someone explain the reason with the answer?

6. what are the disadv. of temp intracoronal splinting? does it interfere with mastication? can somebody refrere me to a place where can I find an explanation to intra and extracoronal splinting?
I would imagine the disadvantage would be loss of tooth structure and a possible need for restoration/enameloplasty once the the purpose of splint is no longer equired. add oral hygiene too.

7. a patient who has had a radiation tr of head and neck, require RCT, what side effects may complicate the treatment?

a. mental depression.
b. decrease clotting time.
c. muscle fibrosis and limitation in mouth opening.
d. increase chance of infection of oral tissue.

1. a,b,c
2. b,c, d.
3. b, c only.
4. b, d only.
5. a,c, d.

option 5 - a,c,d. Picked d because of osteoradionecrosis, c - because of radiation induced musculoskeletal issues , a - because I can't think of a reason to pick decreased clotting time over depression.

ur answer is correct but there was another choice !! which is d and c only "I chose it and it is wrong " .. I was confused because of mental depression !!

8. adverse pupal reaction is more likely to occur when which of the following materials is placed directly into a deep cavity?
a. amalgum.
b. composite resin.
c. calcium hydroxide.
d. ZOE.

amalgam - conductivity issues .

the answer is b.composite resin!! and I don't know why? I thought Ca(HO)2, because it causes an adverse reaction and secondary dentine formation !!

I know too that amalgum need a base of at least 2mm !! and with the composite we dont need to use a base !! confused !!

9. which cell would be the most prominent in initial gingivitis an in established gingivitis?

gingivitis = inflammation of gingiva . So acute - mostly neutrophils , chronic - macrophages and lymphocytes

in ASDA papers it says, neutrophils are found only in the established gingivitis.

Please correct me (quickly,please ; test - very soon ) if I am wrong

 

[Denty8833]

I just found out through the Internet that radiotherapy causes a decrease in clotting time!!!

 

[meridith]

for the desqumative gingivitis - maybe it is one of those MOST correct response things?

And about NUG being 16 -30 years and being most definitely associated with smoking - That is from Burket's .

And thank you for that clotting time . also I checked that Acute/chronic question. Thank you ! I had totally forgotten about that one ! Dang ! exam 2 days away - not a good time to be forgetting important stuff .

 

[Denty8833]

1ppm fluoride >>> ?? In mg???

 

[Denty8833]

Thank you

And no need to stress now, it is normal we r all keep forgetting important things!otherwise we all gonna get 100% in exams

By the way, what do u think of Kaplan qbanks?do I need to buy it while I have only few days left?

[meridith]

Hope to pass ! All I need

And Kaplan - liked it very much . The explanations are great! - If you have 20- 30 days left, you can afford a leisurely review of all ~950 questions - twice. 10-15 days - you may have to speed up a little. Less than 10 - You may be able to do all of it once and review some marked/incorrect ones.

 

[Denty8833]

Well I don't think I have even 10 days to go through Kaplan Qs as I am studying decks now still have ASDA and some of remembered qs !!and cases Qs

I wish If I have time for it


Good luck with ur exam,we all need just to pass !!
Let us know pls abt ur experience

Hi,

The tooth number is # 3 its 1st right molar according to the answer, but I have a doubt too it looks like left first molar # 14 also.

How did they distinguish the side..

18. how many mg of mepivicaine delivered if 5 ml of 3% is given?15,30,75, 150
19. what would u give a pt with renal vascular disease? Aspirin, ibuprofen, Acetaminophen , ketorolac. Acetoaminophen

20. if palpate TMJ area and pain? impacted 3rd molar, flaccid paralysis, 2nd division of V nerve? Did'nt understand question
EXPLAIN THIS QUESTION PLZ
21. primary 1st and 2nd molar extract unilaterally, place? lingual holding arch, band and loop? BLS we prefer, if permanent incisors are erupted then can give lower lingual holding arch(for unilateral loss give always BLS)

22. why occlusal rests placed in RPD?distribute occlusal forses, resist vertical forces? Primarily resists vertica forces, but also has the function of distributing occlusal forces.
so what is the answer? and do u mean resist vertical forces on the tissue?
BOTH ACTUALLY THERE SHOULD BE AN OPTION, OR IF THE QUESTION IS WHICH IS MOST I'LL GO FOR RESIST VERTICAL FORCES
23. why bead major connector? better finish line, contact tissue, hold acrylic better? Contact tissue

can u explain pls?

THANKS for the answers ...

Hey,

Look at the ones in black and bold.

When are you taking exam?
All the best.

[Denty8833]

Hey ... r u done with ur exam or not yet !! I thought u took it already .. GOOD LUCK
pls take a look at the answers below

best site for implant success - post mandible . Though the blood supply is great in the maxilla, the osseointegration is better in the mandible -because of the type of bone (surgery text book- they has the statistics to back it up, but I can't remember the numbers.) I agree with that .. as implant success doesn't have anything with blood supply ... but I would consider ant mandible instead of post !!

are you sure about posterior?

lidocaine toxicity reveral- flumazenil .I know Flum is used for Tx of diazepam overdose .. can u explain how it can be used for LA toxicity?

 

[Denty8833]

1Tx for lidocaine sensitivity? Medazolam, naloxone, flumazanil EXPLAIN
because naloxone used for opiate overdose, and flumazenil use for diazepam overdose
medazolam is sedative sometimes used for allergic reaction
I guess not sure though

4.Extract tooth, and 6 hrs later fever 99.6, pain and swelling? does this consider normal? NO ( guessed) then what it is ??????????

5.last suture to ossify? Lambdoid suture 40-50 yrs
what about frontanale?
6.best radiographe to c the small changed in bone? bite W, priapical, standarized . Periapical
I was thinking the same .. but I just saw yesterday in decks it says for alv bone resorption, bit w is the best?!!
and I saw also for pdl disease priapical and parallel is the best !! now I am confused
PERIAPICAL IS GOOD FOR BONE BUT OCCLUSAL FOR CARIES, YES READ FOR ALVEOLAR BOSS LOSS ALSO OCCLUSAL CAN BE USED.
I didn't say anything about occlusal !! it is bitwing radiograph what I am guessing

7.what is the total amount of flouride that can be prescribed?100,120,160,140? No idea( WHERE DID YOU FIND THIS ANSWER.I didnt and I don't know !!

17. worse restorative material for ID canine? gold, glass, composite, amalgum?
YOU ASKED FOR CANINES SPECIALLY SO ITS COMPOSITE, OTHERWISE GIC
for this I am sure now it is GIC .. as it is the worst restorative material, if for canine or any other tooth ..

24. when does the 2st maxillary molar crown formed"totally formed"? 1-2 years old, 2-3, 4-5

if it is the 1st max molar .. what would be the answer?????

 

[ljohns]

1Tx for lidocaine sensitivity? Medazolam, naloxone, flumazanil . You are right give Diazepam or midazolam for LA allergy or sensitivity I remember now.
6.best radiographe to c the small changed in bone? bite W, priapical, standarized . I am sorry not occlusal I meant Bitewings for caries and alveolar bone loss.
7.what is the total amount of flouride that can be prescribed?100,120,160,140? Is this in mg, what is the amount prescribed in ppm and what is the relation btw ppm and mg?
24. when does the 2st maxillary molar crown formed"totally formed"? 1-2 years old, 2-3, 4-5?
If its max molar its 3 years.

Thanks

Hey,

Which is the best ASDA series which we have to do definetly M, L, but is 1978-released papers worth to do even. Please reply ASAP.
Thanks

 

[beanrule]

Hi! ljohns,

I think its a waste of time. I would say do the past 10 yrs Q papers. The pattern has changed as well. If you have a lot of time then it is a different issue all together.

 

[Denty8833]

I didn't take the exam yet .. so I have no idea what to say ..

but for me as I have no time.. I need to finish decks and I would rather find the time and go through L and M than old 70s ASDA

but in case u have lots of time and u r done with everything, then u can go with the 80s I think better than 70s !! just for reviewing

GOOD LUCK

odontogenic myxoma, ameloblastic odontoma
the differential diagnosis is odontogenic myxoma

what impression material can be affected by latex?
additional silicone

[meridith]

Tetracycline decrease the effect of penicillin due to
penicillin affects cell wall synthesis and need rapidly dividing cells for it to work . tetracycline on the other hand is bacteriostatic , so there is less actively diving cells, thereby reducing/negating the effects of penicillin.

My brain is way too clouded and tired to figure out/look up the rest

14 years old boy with asymptomatic expansion on one side, occlusion change,picture looks like without visible opacity or lucency?
1. Cherubism
2. osteosarcoma.
3. fibrous dysplasia.
4. ossifying fibroma.
??????
3) Fibrous dysplasia.
Definetly not cherubism and osteosarcoma, not ossifying fibroma since the occlusion disturbance happens in fibrous D.


inferior alv nerve block, pierce?
buccinator m, medial pterygoid m.
Buccinator( because its always injected towards the ptergomandibular raphe which involves 2 muscles buccinator and superior constrictor muscles)

with 4 mm implant, minimum space needed?
Can someone answer with explanation
Depends on situation,
6-mm( If single Implant with natural tooth on both sides,1+4+1)
8 mm( if one side implant and other side natural tooth,1+4+3)

what impression material can be affected by latex?
Additional silicone also polyvinyl siloxane ( latex is rubber and different types made of vinyl which can cross reacte and interfere in setting)

Treatment of 1 cm dentigerous cyst aound third molar?
marsuplization
enucleation
radiation
enucleation

old and young patient have the same bone loss on radiagraph, which one has better prognosis?
OLD, in this case because both have same bone loss but at different age group.


to check bone Volume, radiograph?
BWX
PA
substraction
pan
Bone volume and density by subtraction Radiography

composite shrink toward? the light, toward the center
Onn curing shrink towards the Centre,i.e away from the walls

Hope this helps.

buccinator m, medial pterygoid m.
Buccinator( because its always injected towards the ptergomandibular raphe which involves 2 muscles buccinator and superior constrictor muscles)
I can remember I read it somewhere in decks that after LA injection, trismus mostly is due to medial pt muscle !!

with 4 mm implant, minimum space needed?
Can someone answer with explanation
Depends on situation,
6-mm( If single Implant with natural tooth on both sides,1+4+1)
8 mm( if one side implant and other side natural tooth,1+4+3)
can you explain further pls? I can't understand what are those no? buccal lingual or what? THANK YOU
u mean bet 2 iomplants we need 3 mm space? and bet implant and natural tooth 1 mm?
