1.The microflora of the healthy gingival sulcus is predominantly?

Gram- anaerobic cocci and gram+facultatvie cocci
? I think this is the right answer please correct me if i am wrong



2.which unique aspect of cariogenic strains of strep mutans
sets them apart from other oral acidogenic organisms?

a. tendency to form chains
b.secretion of proteolytic enzymes
c.extracellular polysaccharide made from
glucose
d.formation of water insoluble glucans from sucrose
e. four equivalents of acid formed per mole of glucose

3. Vasodilation and increased vasopermeability lasting for
several days in an area of inflammation indicate which of
the following
a. thrombosis
b.release of bradykinin
c.hageman factor activation
d.formation of granulation tissue
e.endothelial cell damage and disruption

Hi:

I would say,
2. d
3. b

 

[ohalechayaakov]

I think the normal microflora in the sulcus is gram - anaerobic rods and fusobaceria. Let me know if I am the one who is mistaken.

 

[crazydentist]

ya...i feel when we talk of gingival sulcus it shld b gram-ve anaerobes mainly....

1. Gram- anaerobic rods
2. d
3. b

 

[PeterHayek]

gram - anaerobies

vasodilatation is produced by bradykinin

 

[skabbaraju]

Answers to the questions:
1. Gram -ve anaerobic rods
2. d
3. b or e ( am I thinking too much if I say that the answer is e, I know bradykinin produces vasodilation duing inflammation but even after several days?)

IT IS GRAM _VE ANAEROBIC COCCI AND GRAM +VE FACULTATIVE COCCI


2.which unique aspect of cariogenic strains of strep mutans

a. tendency to form chains
b.secretion of proteolytic enzymes
c.extracellular polysaccharide made from
glucose
d.formation of water insoluble glucans from sucrose [ANS]
e. four equivalents of acid formed per mole of glucose

3. Vasodilation and increased vasopermeability lasting for
several days in an area of inflammation indicate which of
the following
a. thrombosis
b.release of bradykinin
c.hageman factor activation
d.formation of granulation tissue
e.endothelial cell damage and disruption[ANS]

[keratin]

i think answer for the 1st qu is gm-ve facultative anerobic cocci
2.d
3.hegaman factor activation

 

[drkooks]

i saw question number 1 and number 4....many times on the forum...
and answers always varied between:
gram negative rod and gram negative cocci for number 1

and hageman factor and bradychinin for number 4....

can someone post an answer with an explanation and reference so we can be sure it is right...i tried to find it on wikepedia but did not find an exact answer

Regarding this question,I agree with skabbaraju.Since the inflammation has lasted for several days, it could be due to endothelial damage & disruption.Inflammation lasting too long can cause tissue damage.So I think 😕 the ans for this Q is choice e.
