[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

if anybody can pls clear🙁😕

wat Changes produced by i/v epinphrine administeration from stimulation of beta receptors?
1 cardiac acceleration
2 increase systolic pressure
3 decrease diastolic pressure
4 pupil dilation

ans is 2,3,4. but i am confused as beta receptor stimulation cause inc heart rate then wy not 1st choice& how it decrease diastolic pressure?

 

[laura Maxwell]

if anybody can pls clear🙁😕

The could be associated with epinehrine reversal, where an alpha blocker may be given prior to epineprine. The epi causes a decrease in blood pressure because beta stimulation predominates. (tufts pharmacology).

Correct me, if l am wrong, however,your question did not include an alpha blocker

External bevel incision in gingivectomy where it should end – above GF, JE, CEJ

Polyether advtg over PVS, except – stick to the teeth, disinfection, accurate impression, long working time

👍

Thanks

how to tx for pt have radiation caries ??

 

[BENNY4567]

Hey laura thanx for ur reply but
my ques does not include alpha blocker, this ques is from tuft pharm Adrenergic phygiologic effect q no 15: confusionis epi increase HR then wy not choice inc in cardiac acceleration & how it causes causes decrease in diatolic presure. If u can pls check this ques from tuft.

Remember, Vasodilation predominates over heart rate increase in this case because beta stimulation causes vasodilation and bronchodilation, Also, diastolic pressure affects blood pressure the most.

benny the ans given in tufts is wrong , right ans is 1,2,3,
epinephrine act on both b1 and b2 receptors, sob2 effect will produce vasodialation , main action is peripheral, which in turn decrease diastolic pressure

 

[bombshell]

You do the prep and obturate with GICs. Then perscribe something for the xerostomia.

[BENNY4567]

thanx uabsfm, so epinephrine will not cause pupil dilation? as we read that sympthetic system cause dilation & para do constriction, then should choice dilation not be included?

the question is about action of epi of Beta receptor, not alpha, and pupil dilatation is through alpha 1 receptor, so it will not be in the ans

preparation of cavity for restoration of composite. all cavosurface angles should be
1 well rounded
2 right angles
3 obtuse angles
I think the ans should be 3, but given ans is 2

characteristic of composite resin

1,they can be placed and finished at the same appointment
2 more color stable then unfilled direct filling resin
3 similar to amalgam with respect to co efficient of amalgam restoration
4 finished surface tend to be somewhat rough

ans given is 1, 3, 4 but I think the ans should be 1, 2, 4

prophylactic antibiotic of choice for pt with rheumatic heart dz
erythromycin
penicillin v
ampicillin

ans give is penicillinv, but I think it shoud be ampicillin

plz clarify my doubt

1,they can be placed and finished at the same appointment
2 more color stable then unfilled direct filling resin
3 similar to amalgam with respect to co efficient of amalgam restoration
4 finished surface tend to be somewhat rough

ans given is 1, 3, 4 but I think the ans should be 1, 2, 4
its right ans as they r not more color stable but coff of thermal ex. is almost near to amalgam.
prophylactic antibiotic of choice for pt with rheumatic heart dz
erythromycin
penicillin v
ampicillin

ans give is penicillinv, but I think it shoud be ampicillin
we give amoxicillin, so not sure about ampicillin even??
plz clarify my doubt[/QUOTE

1. which maxillomand record is least reproducible?
a lateral
b centric relation
c protrusive ans
d VDO

pls let me know wy? is it due to reason that it requires condylar guidance

2 In preparing abutment teeth for max RPD, most often need to alter:
a lingual contours of PM & molar
b lingual & proximal contour of PM & molar
c facial & prox contour of PM& M ans

Shouldn't the ans be a i.e lingual contour?

if anybody can explain pls

 

[MitPat]

Hey guys can you tell me which is the best book or material to refer to prepare for NBDE-2 Patient management section. ...thx

if anybody can explain pls

ans to second q is right ans retentive arm is on buccal side of the tooth , and it start above the height of contour and tip end below the height of contour, while lingual side is just for resiprocation, which dosnt require that much modification

 

[uabsfm]

tx of apical # in the apical third of a permanent central incisior includes

immobilization for 2-4 weeks
immobilization for 2-4 months

ans given is 2-4 months, but it should be 2-4 weeks as apical portion is most stable

 

[narihari]

thanx benny for yr ans

thank u uabsfm
if instead of max rpd, he asks for mand. rpd do we still repair facial surface more?

depth of the sulcus is 5mm while the distance b/w CEJ and base of sulcus is 2 mm , what is the attachment loss?

here , ans should be 0, as gingival sulcus depth is grater than pocket depht and so psuedopocket, did my understanding is correct?

evaluation of scaling and root planning done after how many days?
7-10
14-21

dentist cements the porcelin veneer with the light cured resin and the pt returns with brownish descoloration at the margins why?

which of the following is not an advantage of Ni Ti over stainless steel file
maintains shape
flexibility
resistance to fracture

direction of wound healing after extraction in mand arch
outward and upward
inward and downward

which of the following is not recommended for pt who is on nicotinic deaddiction
mucous patches
nicotine gum
buproprione

No, ans is gingivitis.

why gingivitis is the ans , can you plz provide some hint?
I was thinking that there is no PDL and pulp thats why there should be no pain

Which tooth is hardest to get numb?
A necrotic or irreversible, maxillary or mandibular tooth


Please help. ASAP

 

[sekhon]

Which tooth is hardest to get numb?
A necrotic or irreversible, maxillary or mandibular tooth


Please help. ASAP

ans is mandibular tooth
..when other conditions r same......LA works more rapidly in maxilla than mandible as maxilla is more porous.so numb problem rare in maxilla

 

[sekhon]

can u pls tell me how ans to 2nd ques is 5?

pKa is defined as the pH were a drug exists as 50% ionized and 50% unionized ...

most effective radiograph for visualization of mesiodens?
1 occlusal
2 periapical
3 bitewing
4 OPG

 

[sepia]

patient had hit in the jaw and now has a
hematoma in the floor of the mouth, what it is?
(ranula, hemangioma, a common sign of mandibular body
fracture, a common sign of mandibular condyle
fracture, ?)
Bridge is repeatedly breaking – occlusal trauma, poor design, problem metal

What happens if penicillin and erythromycin are given together: summation, potentiation, idiosyncracy, cancellation

1. A vital canine is to be used as an anterior abutment of a 4- unit fpd and it has 2mm remaning coronal; tooth structure . the most acceptable foundation restoration would be

a a bonded amalgam
b a pin retained amalgam core build up
c. a pinr retaind composite build up
d. inetentional devitalisation followed by post and core

2. to improve denture stability mandibular molar teeth should normally be placed

a over the crest of the mandiblr ridge
b. buccal ti the crest of the ridge
c. over the buccal shelf area
d. lingual to the crest of the mandiblr ridge.

3. in restoring a canine protected occlusion, with anterior overbite
of about 2mm. The buccal cusps of
posterior teeth should be flat, BECAUSE they will guide the protrusion

a. both are true
b. only the second statement is true
c. both are false
d. only the first statement is true

4. maxillary first premolars with mesiodistal furcation involvements
are often managed successfully bySurgery.

Therefore, they have a good prognosis and can be included as key
abutments in a fixed prognosis.

a. both statements are true
b. both statements are false
c. the first statement is true, the second is false
d. the first statement is false, the second is true

ANS to this ques, somewhere ans given d and other b, if anybody can ans it with explanation pls???

5. why is it advisable to dispense the liquid component of cement of
cement immediately before mixing?

a. to avoid absorption of moisture from the air
b. to avoid spreading over a large area of the slab
c. to allow tempering of the powder by the mixing slab
d. to reduce the temperature influence of the mixing slab
e. to prevent evaporation of the volatile components.

According to the buccal object rule, when the xray tube is repositioned either at a more mesial or at a more distal angulation and a film is exposed, the root or canal farther from the film (the buccal) will:
a. move in the opposite direction that the cone is directed
b. move in the same direction that the cone is directed..... ANSWER
c. not move at all

If you use the SLOB rule why isn't the answer A? Am I missing something here
