B-abrupt and fwd
C-abrupt and behind

B??? IS THAT RIGHT???

hi friends, would you please help me find the answers,

To ensure better thermal and protective insulation of the pulp during a capping procedure, calcium
hydroxide should be:
A. Applied to a thickness of 3.0 mm.
B. Placed in all cavity preparations.
C. Covered with a stronger base.
D. Preceded by application of a cavity varnish.
E. Preceded by application of a zinc phosphate cement.

2. In shaping and cleansing the canal of a vital maxillary central incisor, a practitioner has inadvertently
perforated the apical foramen. This error can result in each of the following EXCEPT one. Which one is
this EXCEPTION?
A. Pain to the patient
B. Enlargement of the foramen
C. Trauma to the apical tissue
D. Necrotic tissue being forced into the apical tissues

1.To ensure better thermal and protective insulation of the pulp during a capping procedure, calcium hydroxide should be:
A. Applied to a thickness of 3.0 mm.
B. Placed in all cavity preparations.
C. Covered with a stronger base. (to provide isolation)
D. Preceded by application of a cavity varnish.
E. Preceded by application of a zinc phosphate cement.

2. In shaping and cleansing the canal of a vital maxillary central incisor, a practitioner has inadvertently perforated the apical foramen. This error can result in each of the following EXCEPT one. Which one is this EXCEPTION?
A. Pain to the patient
B. Enlargement of the foramen
C. Trauma to the apical tissue
D. Necrotic tissue being forced into the apical tissues (since the tooth is vital)

stability of implant..arrange in increasing order?

anterior maxilla, anterior mandible. posterior mandible, posterior maxilla.

can anyone guide from where to study perio medication part?

 

[drika11]

MORE STABLE TO LESS--- MAND ANT,MAND POST,MAX POST,MAX ANT
MINIMUM DISTANCE FROM ONE IMPLANT TO OTHER --3mm
MINIMUM DISTANCE FROM IMPLANT TO ADJACENT TEETH--1mm

WHAT IS THE DISTANCE FROM IMPLANT FROM ANATOMICAL STRUCTURE LIKE MAND CANAL?

 

[docasrpa]

r u sure..
i checked from some online resources it was..mn anterior most stable followed by mx post, mn post and mx anterior

 

[PeterHayek]

Hi guys..I'm an oral surgeon and have been doing implants for 3 years before I came to Canada....

The stability (the primary stability only) of the implant depends on the quality of bone, more the bone is compact, more the implant will be stable which leeds us to conclude :

The most stable region is anterior mandible, posterior mandible, anterior maxilla, and posterior maxilla.

As for the distances : (calculated from the center of the implant)

Implant - tooth : 2-3 mm
Implant-implant : 7 mm
Implant - anatomical structures : 1mm

Why do you not give erythromycin with tetracycline?

Best radiographic way to see small bone
changes? BWX, PA, standardized

) What is the ideal gingiva for root planing?
Healthy, fibrous

What would make the solder joint of a FPD stronger?
A. Wider Occlusal-Gingival
B. Wider Buccal-Lingual

If palpate tM] area ,there is pain? -
Impacted 3rdmolars
Flaccid paralysis of affected side
2nddiv. of V nerve


Failing Amalgam- why replace with gold crown?
Better margins
Better contours

 

[docasrpa]

worst material to do impression for crown?
PVS
polyether
reversible HC
irreversible HC
polysulfide

i think it is ireversibe HC..agar. Am i right?

 

[docasrpa]

Trauma trom occlusion with implants does not cause?

mobility, wear, broken screws, gingival inflammation, broken abutments

please reply

 

[PeterHayek]

Gingival Inflammation is the answer

agar is precise but it's problem is that it's difficult and complicated to manipulate

the answer is reversible HC like alginate which has not a good precision

 

[docasrpa]

thanks

[drvipul81]

Trauma trom occlusion with implants does not cause?

mobility, wear, broken screws, gingival inflammation, broken abutments

ans ;gingival inflamation

 

[MitPat]

You guys are right the ans is gingival inflammation as the last thing you want is gingival inflammation also called ( Periimplitis) which is the initial sign of Implant failure if not corrected. One more thing you have to clean that area not with regular scalers but use only plastic scalers.👍

Some where on the website i had found that if you score 275 out of 500 then its a passing score in NBDE-2 so go for it if you have a target
