I guess its aphthous ...

I think it has to do with being stressed out in college, aphthous ulcers occur when you are stressed due to being immunocompromised.

No Down syndrome patient is not prone to high dental caries from what I know..

agreed..

(from decks)

Down syndrome is a congenital defect caused by a chromosomal abnorrnaliy.-
(trisomy 2 l). It is marked by various degrees of mental ******ation and characteristic
phvsical features such as a short, flattened skull, slanting eyes, a thickened tongue
r.tissured), broad hands and feet and other anomalies. Other oral rnanifestations include
mandibular prognathism. increased incidence ofperiodontal disease, delayed eruption of
teeth. higher incidence of congenitally missing teeth, malocclusion, and enamel dysplas
ia.

[MattBiggar80]

i dont think Neutrophils aer in healhty gums. only when there are problems. I think the answer to question 8 is C.
im not 100% sure dont know.

 

[missi85]

2. 15% of tissue is composed of inflammatory infiltrate.( Wikipedia )

 

[missi85]

3.cell common in early lesion........ Plz correct me if wrong
Lymphocytes n PMN
(Wikipedia , mossy page no 248)

 

[missi85]

i dont think Neutrophils aer in healhty gums. only when there are problems. I think the answer to question 8 is C.
im not 100% sure dont know.

According to Wikipedia n mosey healthy gingiva is characterized by small numbers of leukocytes migrating towards gingival sulcus n residing in JN epithelium. Spare lymphocytes n plasma cells in connective tissue.

Confused

What is the interference seen in group function

 

[Breezyme]

Please can anybody answer these ques

The most effective way to differentiate ameloblastoma
And keratocyst

Cytological smear

None

Correct me if I m wrong
I think MRI
Ameloblastoma: shows mixed solid n cystic pattern with thick irregular walls. Papillary solid structures projecting into ledion.
OKC: usually unilocular with thin poorly enhancing wall.

 

[Breezyme]

Thanks Missi85 . Same answer
Is there in Q bank DMD but I was little confused between
MRI and Cytological smear. I checked online with google , they said
Microscopically

One more ques was what is mistaken for proximal
Caries in posterior teeth
What's the answer
Carabelli cusp OR CEJ

 

[DancingKoala]

Hi, guys.
This week, I am trying to study/finish endo section.
I have gone thru Mosby's review couple of times but I wasn't able to answer any of the diagnosis and treatment planning questions I found in dental deck/released exams.

For example, if a question gives us a pt with age, what happened to the tooth, vitality...etc and tell me what I should do with options such as pulpotomy, pulpectomy, root canal, don't do anything...etc. I don't know how to approach this type of questions

Here are some examples and I would appreciate it if you can explain how you approached to come up with answers.
1. 4 mandibular incisors were traumatized 3 yrs ago. x ray shows bone rarefaction i the region of the apices of the incisors.
Answer = test the pulp vitality and perform RCT only in those that don't respond to pulp testing.

2. Pt has severe, throrrinb pain, aggrevated by heat, biting, and touching.
answer = RCT

3. permanent tooth crown got fractured, creating 1mm pulp exposure for 30 min
answer = direct pulp capping with calcium hydroxide.

4. 4 yr old w/ frequent spontaneous pain in primary mandibular 2nd molar. Necrotic pulp
answer = pulpectomy

5. 5 yr old child has a carious lesion in her primary mandibular 2nd molar. No mobility but small draining sinus tract adjacent to the tooth
answer = pulpectomy

6. 8 year old has exposed vital but inflamed coronal pulp in #14
answer = pulpotomy

7. 7 year old patient has fractured #8, 3 hrs ago, 2mm exposure of a bleeding pulp.
answer = pulpotomy w/ calcium hydroxide.

8. 6 yr old pt, tx choice for necrotic pulp on permanent first molar
answer = apexification

9. 34 yr old black woman. Asymptomatic. No decay or destruction. Slight perio disease. Periapical radioluencies on two mandibular central incisors. positive pulptal test.
answer = no treatment necessary at this time.

10. A patient experienced a blow to the mouth. Horizontal mid-root fracture of a maxillary central incisor. No mobility. Asymtomatic. negative pulp test. No radiographic lesion.
answer = render no treatment at this time and periodically recheck clinically and radiographically.


Thanks in advance.

 

[Breezyme]

Please anybody Answer my Ques

 

[missi85]

Thanks Missi85 . Same answer

One more ques was what is mistaken for proximal
Caries in posterior teeth
What's the answer
Carabelli cusp OR CEJ

I think answer is CEJ.
CEJ is more common site for cervical burn out. Appear as a radiolucent area between CEJ and alveolar crest. It can be misdiagnosed as caries.

Carabelli shd appear radio opaque same as normal tooth structure.
Just a guess. Let me know what you think. What other options are????

 

[Breezyme]

Thanks missi85
Actually I was thinking the same ans. but in
Q bank DMD answer was Carabelli cusp . Please can u
Suggest me if Q bank DMD is good for studying
Or not .

[gursimran]

please answer the following questions:-
1.Reversible and irreversible pulpitis can be differentiated by which test:
a)cold test

c)percussion
d)ept

2. Overretained primary tooth should be:

c.........
d.........

4). Informed consent comes under which 5 laws of dentistry?
a)justice
b)veracity
c)beneficary
d)non malice
e)

5. Is mandibular complete denture mandatory for balancing of maxillary complete denture?

 

[Drgurya]

but i think b2 receptor also causes vasodilators.

Ph below 5.5 where reminerlaization start. you mean reminralizaation or demineralization?

 

[Breezyme]

Please can anybody suggest me where to buy
The Tufts material. I do have the material
But I m not sure if that's enough . Please
Guide me what's all there in tufts book
And how old is it ? So that I can check if I have
The rt material .

 

[Breezyme]

Please can anybody guide me a about
The tufts stuff

 

[doc76]

Hi everyone ,I have a question about VDO.Decks say dec VDO results in excessive inter occlusal distance when mandible is in rest position .that mean increased freeway space.I think dec VDO should dec freeway space. Pls explain.thanks

Thanks in advance.

1) if pulp is vital no need for RCT if pulp is not vital RCT .
2) severe throbbing pain, aggregated by heat ,irreversible pulpitis ,do RCT.
) permanent tooth with pulp exposure , diagnosis depend on the age ,if pt is old do RCT if its a kid and apex is not fully closed pulp capping.
4) 4 yr old primary tooth , necrotic pulp do pulpectomy ,Remember it's. primary tooth.,if its a permanent tooth might need apexification .
5) 5 yr old with carious lesion ,draining sinus tract mean pulp is necrotic so do pulpectomy .
8)6 yr old ,necrotic pulp permanent tooth do apexification . Coz apex is not closed yet.
9) 34 yr old , asymptomatic, pulp vital no endo treatment required periapical radiolucencies could be perio issue.
10) pt with horizontal mid root fracture , don't do the pulp test right away it could be negative even if pulp is vital.so wait for some time do the pulp test again and make diagnosis.most tooth with vertical root fracture has poor prognosis.prognosis in horizontal fracture depend upon extent of the fracture .
6)8 yr old with vital but inflamed coronal pulp,remove coronal pulp put ca ( oh)2. Root of #14 close around 10 yr. so need that pulp for apex formation if the whole pulp is infected or necrotic do apexification.
7) same explanation as above.

Please can anybody tell me what's the latest
Tufts notes and from where I can get those .

Thanks

 

[Visitacion]

I used it and it was helpful. I got questions very similar in my test. Dental decks 2013-2014 are the best. I got a lot of questions from these decks. I am selling mine. my email is [email protected].

 

[Visitacion]

I have tufts 2005.I tried to get a newer edition but I could not.
I am selling my dental decks 2013-2014. my email is [email protected] if you are interested.
I took my part2 on June26-27 and I passed it.
I did dental decks 2013-2014, crack, QbankMDM, Tufts for farmacology,

 

[Visitacion]

Qbank MDM is very good. It helped me a lot. just do dental decks first because I found some wrong answers but in generally it is helpful. The crack is good as well. I liked the fact that I could do them several times using just a click, for me it is better that the paper test.

www.simplenursing.com is very good for pharmacology.
Tufts is good as well. I got 2005 edition.

study dental decks 2013-2014, do not do an older edition,do not take that risk!!!

3. same question except with horizontal fracture.

Thank you.

 

[Sugu]

Hi guys,
I'm planning to take .nbde 2.. would u plz tell me the materials?!!!!

For Part 2 u need Mosby for theory, Dental Desk if possible recent edition (its costly) I used 2011-12 and it was enough and economical. ASDA papers.

 

[alaamsoliman@gmail. com]

Thanks a lot for responding Sugu .. can anyone send me a soft copy of ASDA?!!
Thanj u guys for ur help.

 

[anonyperson]

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.

Yet another wrong explanation - the answer is rifampin. That is the only one that has been shown to definitely cause problems.

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.

 

[drmcard]

This patient is at risk of infective
endocarditis. To minimize this risk, the
dentist should place the patient on which of
the following dosage regimens of oral
amoxicillin?
BEFORE AFTER
TREATMENT TREATMENT
A. 3 g 1 hr prior 1.5 g 6 hrs later (answer given)
B. 2 g 1 hr prior 1 g 6 hrs later
C. 3 g 2 hrs prior 1.5 g 6 hrs later
D.3 g 1 hr prior None

CAn anyone explain this y they put A as the answer. asda reprint K clinical case H Q.78
I think the answer should be B.

 

[drmcard]

effects of H1 blocker EXCEPT

a. CNS increase

b. CNS decrease

c. increase acid secretion

d. resp depression

e. local anesthesia

I think it should be D but not sure? Is that right? dont know answer.

 

[Torbe]

Does anybody know this one? Im tired and i think i forgot this one:

tetracycline stains are enamel, dentin or both? thanks

The answer for you DRMCARD. H1 blockers causes CNS depression of midbrain and also is anti emetic, vasoconstriction and vasodilator, so thats why i will say you could consider respiratory depression as part of effects, but not sure. I will go for CNS increase.
