Which of the following materials is most likely to cause adverse pulpal reaction when placed directly in a deep cavity preparation?

4 ZnOE
5 Polycarboxylate cement

Ans is 2 . according to released papers

 

[toothache101]

can someone explain the buccal object rule when taking xrays?

 

[spa]

can someone explain the buccal object rule when taking xrays?

It is simple.
Imagine X and Y are superimposing on a radiograph. this technique is to find out relative positions of X and Y ( lingual and buccal)
Just remember SLOB. ( Same side Lingual and Oppsite side Buccal)
think X moves to distal upon moving the cone to distal in second radiograph, X moved in the same direction as cone. so X is lingual to Y.
If X moved in mesial direction upon moving the cone in distal direction in the 2 nd radiograph, X is moving in oppsoite direction compare to cone. so X is in buccal to Y.

 

[toothache101]

why is the Wharton's duct which is in the mandible also called submaxillary gland?

 

[ICDK]

Hi! Please help ...I'm taking my NBDE II in less than 10 days . If you have any recent review questions Please post them and I will post my test questions after my exam...it's a deal Please advise on what i should focus on. I've been reading the Kaplan review book but i just can't remember them. Should I just look at the released exam questions ? Please help !!! Thank You !!!

 

[toothache101]

there are people who got in the 90's with just kaplan, so it must be good. i heard mosby is good too.

 

[ICDK]

Thanks for the encouragement I know I should review the kaplan but it's just too long and i don't have much time left

 

[dmband420]

How many questions can you get wrong on day one and still pass?

 

[toothache101]

over half the questions. i heard as long as you get around 50% you are in good shape.

 

[dentalworld]

Ans is 2 . according to released papers

yes is agree thats y confused y it is composite resin and not amalgam can some one explain.

one more question i have doubt about of ortho:

All of the following r functional appliances except:

Yes antibiotics, candida infection, and oral rinses cause hairy tongue, as well as poor oral hygiene.

Hello everyone,
Can you answer this question?
Compared with unstimulated saliva,stimulated saliva is benifical of high level of
A calcium B phosphate C PH D mucin
Thanks

 

[dentistry]

Hello everyone,
Can you answer this question?
Compared with unstimulated saliva,stimulated saliva is benifical of high level of
A calcium B phosphate C PH D mucin
Thanks

yes,it is ph as unstimulated saliva have high inorganic phosphate but less bicarbonic acid as compare to stimulated saliva. stimulated saliva have high ph which is more important for buffering action for prevention of caries.
please do correct me if i am wrong

 

[SoCalDentist]

sorry if this is obvious; is there a key posted anywhere for the NBDE !! released item booklet (2006); I have tried to search but there are just too many posts to possibly scan through.
thanks

Hey thanks anyway, just found them.

 

[toothache101]

I thought stimulated saliva has more of an acidic ph so it can help break down food, correct me if I'm wrong

Hi all friends
can anyone explain ELLIS CLASSIFICATION for traumatic injury?

 

[drika11]

ELLIS CLASS I - involves enamel
ELLIS CLASS II - involves enamel and dentin - pt complains of temperature sen
ELLIS CLASS III - extends into the pulp- pt may have severe pain or no pain due to loss of nerve function - have a visible area of pink, red, or even blood at the center of the tooth.

SEE YOU ON SATURDAY AT NOON!!!!!!!!!!!!!!!! STUDY WELL!

 

[dentalworld]

Which of the following is LEAST affected by occlusal trauma?

1. Gingival attachment

2. Alveolar bone

3 Periodontal ligament

4 cementum

what stand for class V,VI,VII,VIII?

 

[drika11]

Which of the following is LEAST affected by occlusal trauma?

1. Gingival attachment

2. Alveolar bone

3 Periodontal ligament

4 cementum

definetly----- A
because you will definetly have:
loss of alveolar bone
increase in tooth mobility
increase in width of the periodontal ligament space
EFFECT ON oblique fibers of the periodontal ligament
EFFECT ON cementum
EFFECT apical area of the periodontal ligament

Hi Guys,
Please Help Me With This Question

Why Is Tetracycline Given In Pt With Gingivitis?

 

[docasrpa]

i read that primary teeth r in occlusion at age 2.5-3 years. is that right? or is it 23 months?

 

[MitPat]

Only after scaling you can prescribe the tetracycline as it will leave the concentration in gingival pocket.I dont think without cleaning the area it will help by any means. thanks.
