cephalosporin (tufts pharmacology

 

[briansle]

Page 27, mosby: most common coz is coronal leakage.

Yea your right that's what mosby's says. But USC courseware has questions that ask why most rct's fail, and they say its due to cleaning and shaping the canals. Not sure which to go with.

instruments used for pulp canal therapy are sterilized by using
hot oil
an autoclave
boiling water
cold sterilization
glass bead sterilizer

here it says ans is an autoclave, but I think the ans should be glass bead sterilizer,
plz clarify the doubt

 

[BENNY4567]

thanx uabsfm, actually i ans in same way but my confusion is if its a case of loss of max 2nd molar in mixed dentition period , either its unilateral or bilateral we give nance as expalined by sunshine. its due to reason that if we give band and loop then primary maxillary 1st molar can exfoliate and bandloop is of no use. Then wy not for loss of primary max 1st molar, we give nance again in mixed dentition as we have to give band on canine and that is primary too and can loss? or reason is max canine exfoliate at last?
am i lost b/w nance and bandloop?

if unilateral then BLS if bilateral loss then Nance holding arch

 

[BENNY4567]

ans should be immersion in glass bead sterlizer for 5sec( i read in book). as we can do autoclaving but it coz rusting to these instruments

yes you are right, because 1st premolar eruprs before canine, and deciduous canine lasts for loger period then decidous molars

I also go for glass bead sterilizer but in ASDA qs paper autoclave is given as an answer choice
thanx

pat with severe periodontal involvement requires flap surgery on the complete mandibular arch , a potential problem is damage to the

1) Most common reason for amalgam failure
2) Most common reason for Posterior composite failure?
3) We dont routinely give Abx for Periapical abscess right????

Thanks for any attempts in advance...

 

[narihari]

can u pls explain the ques little clearly with choices?

yes..re-imbursemnt could be any % decided..80/50/20

 

[BENNY4567]

1) Most common reason for amalgam failure inadequate depth
2) Most common reason for Posterior composite failure? unable to maintain total dry condition during etch/ stress: can u pls give choices
3) We dont routinely give Abx for Periapical abscess right???? mainly do drainage and give antibiotics too after culture

Thanks for any attempts in advance...[/QUOTE

anybody pls?

anybody pls?

temporary--consv tooth structure

 

[narihari]

can u pls explain little wat this re-imbursement % is? i can't get this

just googled it:

Direct Reimbursement Plans

This is a self-funded benefit plan — not insurance — in which an employer pays for dental care with its own funds, rather than paying premiums to an insurance company or third-party administrator.
You, the patient, pay the full amount directly to the dentist, then get a receipt detailing services rendered and the cost, which you show to your employer. The employer reimburses you for part or all of the dental costs, depending on your specific benefits.

Your company might reimburse 100 percent of your first $100 of dental expenses and then 80 percent of the next $500, and 50 percent of the next $2,000, with a total annual maximum benefit of $1,500. Or it might reimburse only 50 percent of your first $1,000, resulting in a $500 yearly cap.

 

[briansle]

3) We dont routinely give Abx for Periapical abscess right????

Thanks for any attempts in advance...

1: Complete canal debridement - most important step.
2: drainage
3: antibiotics - only if you have diffuse rapid swelling.

QUESTION : The fenestration technique for mandibular vestibuloplasty is based on the premise that the mucosal attachment will

1. not cross the skin graft.
2. not cross the mucosal graft.
3. not cross a fibrous scar band.
4. be maintained in its lowered position by the new denture.

aNSW Is 3, can you explain? and what is the fenestration technique?

fenestration tech. is done to increase attached gingiva, periosteum is removed and scar formed will prevent gingiva movement and shrinkage of attached gingiva.

pls explain these q:
1. periapical of mandibular anterior teeth showing moderate perio bone loss on #23 and #24 & marked bone loss 25& 26. u r informed that 23, 24 r to be extracted and bridge is constrcted from:

2. dentist is doing research on 5 unrelated pt. with different background. he record data, dentist is doing wat kind of research?
a clinical trial
b cohort
c cross sectional

3. based solely on sharp transient response of pupl to hot stimuli, wat is periradicular diagnosis?
a acute apical periodontitis

large condensers and laterally applied condensation force are recommnded to ensure complete condensation for

admixed,
spherical
lathe cut
conventional
high copper

 

[uabsfm]

post and core is preferred over post crown for an abutment tooth because

it is stronger
it require less chair side time
better esthetics
can be treated as an independant abutment

pathognomic symptom of chronic apical periodontitis

swelling
intermittent pain
tenderness to percussion
tenderness to palpation
none of the above

hey narihari,
i read in mosby that spherical amalgam is better for making proximal contact but couln't find that it requires large condenser?
can u pls tell from where did u read it?
