NBDE part II question

[funstuff]

---

Members don't see this ad.

can someone try to help answer questions:

Daily cleaning of root surface by the patient has been shown to
a. cause root sensitivity
bcause root resorption
c. stimbulates epi attachment
d. allow remineralization of root surface

i think it is d

 

[pepelmas]

the base of the incision in the gingivectomy technique is located

A) in the alveolar mucosa
B) at mucogingival junction
C) above the mucogingival juntion ans

can some one explain this.

[drpuri18]

Antibiotics help to reduce pockets by
a. resection
b. shrinkage
c. reattachment
d. regeneration


Sarna/mirell/kathrm

Wht I have read in carranza page 683 chapter chemotherapeutic agents in treatment of periodontal pockets edition 9th ..is studies demonstrate that tetracyclinefibres applied with or without S&R reduce probingdepth,bleeding on probing,periodontal pathogensand provide gains in clinical attachment level..the fibres provided 60% greater improvement in clinical depth and clinical attachment level than scaling alone...

According to this i will go with option C that is REATTACHMENT


Any opinions anybody

hi

 

[cosm]

My suggestions, tell me what you think

thanks Sarna
16. keratosis happen where in the mouth
a. palate yes
b. buccal mucosa__ANS why this answer?
c. floor of mouth
d. upper lip

ANS__buccal mucosa..coz....
Pathophysiology

The white patches of frictional keratosis that develop in the oral cavity represent a chronic, low-grade, mechanical process that is analogous to the formation of a callus on the skin. The most common local factors involved in this process are tissue chewing (mainly on the buccal mucosa or lips), ill-fitting or irregularly surfaced removable dental prostheses (dentures), fractured or malposed teeth, poorly adapted dental restorations, orthodontic appliances, improper toothbrushing, and constant mastication on edentulous alveolar ridges. The constant irritation stimulates the production of excessive keratin, with a subsequent change in the thickness and the color of the involved mucosa.


correct if Im wrong

 

[feelgood]

k

hey isnt the answer the keratosis i smost common on buccal mucosa?

 

[cosm]

hye feelgood..
even I think its buccal mucosa..especialy frictional keratosis

 

[feelgood]

hye feelgood..

Dr Puri,
I checked the chapter you suggested and I don't know, maybe I don't get it, but it does not say anything about reattachment. The same author in that book explains what reattachment is, and I don't think this is the answer.
Also, Periostat is proven to have the effects you cited, but other antibiotics are used in perio too and they do not have the action of Doxycycline. I think the Q referred to antibiotics in general.
These are only my thoughts. Tell me what you think.

Sarna you are right, I read about reattachment yeap and carranza said that is only used when is recovering from a trauma, but if is from a periodontal disease then we should call new attachment and not reattachmet in this case.... well I still confuse as well because the thing is that others antibiotics are no making anything, because of that we only give antibiotic only if the patient with the periodontal disease have limphoadenophaty or sistemic manifestation (with the exeption of ANUG or Periodontosis to hellp the immune system in this last)... in fact antibiotics such as minocyclyne and doxycycline we can give always that the packet is formed with more than 5mm and bone loss, is only comming in 20mg in case of doxycycline that is not acting as antibacterial anyway, just because of that I give mentiong of doxycycline on particular, in other hand, now if you said that is antibiotic on general then they are no explainig or any more details... I guess that in this Q we are missing important information anyway😕 I am out of this Q

1.what type of prep do you do if you have small mesial and distal lesions on max molar?

2.what's the best way to load implant?

3. what prep is it okay to leave undermined enamel? (class 5 occlusal surface? Or class 3 facial)

anyone suggestion??

 

[gaya]

the custom tray used for the making the CD final impression must
1.have horizontal handle
2.extend to the bottom of the vestibule
3.stored in water until use
4.create adequate space for teh impression materials

 

[mmasurf]

adequate space for the impression material

 

[dentistgirl08]

1.what type of prep do you do if you have small mesial and distal lesions on max molar? mo and do

2.what's the best way to load implant? endosteal loading/ progressive loading ( im not sure)

3. what prep is it okay to leave undermined enamel? (class 5 occlusal surface? Or class 3 facial) Class 3

anyone suggestion??

anyone else any other answ ? pl post

 

[rose82]

If you have a pt that has lost the provisional crown and comes to the office to put the final one but it doesnt sit, the reason is
1.tooth mesialization,
2. Perio abcess because of food impaction,
3 lower tooth that has extruded

..[/COLOR]Trismus is most frequently caused by
A. tetanus.
B. muscular dystrophy. 🙂
C. infection.
D. mandibular fracture.


Isn't the answer infection? Just read " Pericoronitis (inflammation of soft tissue around impacted third molar) is the most common cause of trismus." Thus wouldn't it be due to bacterial infection?

What specific Muscular dystrophy diseases cause trismus?

2. 88 lbs patient is given 2 cartridges 1.8 ml each of 2% lidocaine with 1:100,000 epinephrine. Approximate what % of maximum dosage allowed for this patient was administered ?

A 10%
b 20%
c 40%👍
D 60%

please can u explain your calculation?

R u sure this is right? In the decks they say that the unit of conversion for maximum allowable lidocaine is 3.2mg/lb or 7mg/kg.

If this is the case then: 3.2mg/lb x 88lbs = 281.6 mg is max allowable dosage
Take 72mg =(two carps) since that is what was administered.
72mg/281.6 = .255 x100 = 25.5%

So shouldn't the answer be around 20%?

Can someone else clarify how they get 40%? one of us has the wrong units of conversion for the maximum allowable dosage of lidocaine.

1) which tooth has more nutrient canals? I dunno? what is this? max lateral? the tooth that has most accessory canals has more nutrient canals?

2)which oral lesion blanches on compression? nevi, also hemangioma, telangietasis. There are alot. Depends on the answer choices given. Ecchymosis does not blanch. Hemangioma does. Thus any lesions that are vesicular probably blanch. Those that are macular don't.


4) Current tecnique accepted to reduce pocket depth except one?

gingevectomy/
gingval currettage/
s&rp/
debriment surgery/
osseous surgery I'm guessing this is like crown lengthening procedure.

5)The drinking water supply of a community has a natural f level of .6ppm.the flouride level is raised by .4ppm, tooth decay is expected to decrease by what % after 7 years?
somebody please answer this.


7) keeping the Kvp and Msa the same and changing from D film to E, to keep the same intensity one should
increase the Kvp and MsA
decrease both? E is faster than D? Thus you would need less radiation to achieve the same desired effect. Therefore decrease both?
increase kvp and decrease MsA
increase Msa and decrease Kvp

8) if someone cant take ibuprofen what can u give them?
aspirin Not sure. Both r NSAIDs. So if they're allergic to ibuprofen is it safe to give aspirin. Demerol and pentazocaine r both opiods. Dunno. Maybe demerol is best
demoral
pentazocaine

9) why give hydralazin with chloral hydrate. My guess: Chloral hydrate is a sedative that can cause cardiac arrythmic effects. Hydralazine is antihypertensive. I think via alpha 1 receptors. I guess it'll help prevent cardiac arrythmic effects

10) A 65 yr old lady living on 40k pension per year, wants to get a treatment. She does not have any other physical abnormality besides tooth pain in her molars. From where does the money covered for her treatment come from?
1) Medicaid
2) Medicare.
3) Private Insurance
4) Others insurance.
Read in Mosbys that medicaid and medicare only cover dental if it's tied in with other health problems. Exp: Full mouth extractions prior to recieving radiation therapy would be covered by medicare.

what is the total amt of fluoride that can be prescribed?

 

[happy2bhappy]

If there can be no epithelial attachment then why do we do SRP's and see decreased pockets. The purpose of an SRP is to clean the cementum and disrupt the sulcular epithelium so that you can gain attachment through long junctional EPITHELIUM. So therefor no grafting would be necessary for new epithelial attachment. However that is not the answer to this question because the patient can only clean .9mm into their pocket and wont disrupt the epithelium. So the answer to this question is for remineralization. Daily brushing wont cause sensitivity or else every geriatrics patient that has good hygiene would be in pain. Now if the question stated using an extra hard toothbrush i would be inclined to say sensitivity.

to get attachment you need cementum and if you have recession for a long time you will lose cementum over time b/c if we have a very thin cementum this cant will dissolve/erode over time in this enviroment..so the ans can not be reattachment, so you are correct ans is d

what is the difference btw potency and efficacy of a drug

 

[Star Jasmine]

Efficacy: referred to as "Intrinsic ability", maximal, or "ceiling effect". It is

the maximum effect a drug can bring about, regardless of dose.​

Potency: is the relative concentrations of two or more drugs that produce the same drug effect.

Hope that helps!

anybody know answ to what we need to find our condylar and lateral shift guidance? I almost though tit was right lateral excursive movements because maybe that causes bennit shift in the left condyle. Thus we can use that shift to tell us about condylar movements?

9 the action f the Hawley appliance is mainly
a. intrusion
b. tipping ​

c. bodily movement
Hawley appliance is passive and often used to retain teeth after ortho tx. It can accomplish minor tooth movement, I'm guessing my tipping? Tipping is the easiest movement to achieve.

28 when do you do serial extraction
a. for space deficiency in mandibular anterior region
b. for space deficiency in mandibular posterior region
c. for space deficiency in maxillary anterior region ​

b. for space deficiency in maxillary posterior region
Guessed. Usually see alot of mand ant crowding

Dysplasia in red blood cells can lead to AML.

Not sure if autograft is the best answer choice. I guessed since its coming from you own body

mine was exactly similar with lots of behavior mgt and community dent..
learn the % of ppl with perio dis
% of h2o fluridation
and similar stuff...
behavior mgt - desensitization, cognitive therapy, behavior shaping, passive something, it wud be good to skim thro beh mgt in a textbook. I didnt and i am sure iam goin to pay for that. second day was comparatively easier and relaxing.

In reference to toothburshing, I know that the bristles penetrate into the gingival sulcus but does anyone know approx. how much (in mm)?

I also need help with the whole emergence profile and implant info. Where exactly should it be in relation to the CEJ?

Thanks for the help in advance!🙂

[briansle]

where shouls i study implants??????anyone plssss guide...

I think the best way to study implants is just old questions. They seem to only test a few concepts on implants. Just know these few concepts well and that should be all that you need. Mosby's and decks I did not find very helpful. And going to textbooks is inefficient. Better to go over old questions and reverse engineer them.

Questions that address :

• Spacing is 3mm apart.
• Plenty of air cooling and water irrigation to prevent overheating.
• Smoking is bad for implants.
• If any mobility complications occur, must redo implant
• .1mm bone loss/yr is usually seen
• The best area to place implants.

This is pretty much all they really cover I think. Unless you got the exam that is implant-heavy 👍

 

[briansle]

In reference to toothburshing, I know that the bristles penetrate into the gingival sulcus but does anyone know approx. how much (in mm)? I'm assuming that if you really tried, you could get the bristles all the way to the junctional epithelium. And if your biological width is 2.04mm I would say sulcus depth averages 1mm? Answer I would put is 1mm.

I also need help with the whole emergence profile and implant info. Where exactly should it be in relation to the CEJ? Good question. If anyone knows this please educate us.

Thanks for the help in advance!🙂

Yea I know...it was impossible to find but...

Implant emergence profile: http://jada.ada.org/cgi/content/full/138/3/321

​

.In order to achieve proper emergence profile, and to maximize esthetics, the fixture should be placed approximately 4mm apical to the CEJ's of the adjacent teeth..
I also agree with your tooth brushing response. Thanks
