Pas fibrin k kheili moheme az plasma

Fibrin is a fibrous protein involved in the clotting of blood. It forms a mesh-like structure, helping to stop bleeding by creating a blood clot at the site of injury.

Q

PRF compare to prp?

A
  • Less centrifuge time
  • without anticoagulants
  • Three layer (PPP-PRF- red corpuscles base)
  • longer growth factor release profile
  • Leukocyte between Fibrin clot & Red corporals
    layer
  • it is not only accumulation of cells & growth factor
    but also a scaffold

A

Red Corpus cels base

24
Q

ppp?

A

as cellular plasma

25

PRF?

A

Fibrin clot

26
Q

main component of PRF.

A

Bioactive molecules: PDGF,TGF-B , IGF, EGF
provisonal extracellular matrix (3D scaffold): fibrin Matrix:
Fibronectin , Vitronectin
cell types: planets> Leukocytes GRBC

27
Q

How to make PRF?

A
  • Fixed angle centrifugation technique (4s deg)
  • Horizontal centrifugation technique.
28
Q

protocols for PRF:
L-PRF & A- PRF?

A

L-PRF = (Leukocyte-PRF):
2500_3000 rpm
10-12min

A- PRF = (Advanced - PR F) :
1300 rpm
8 minutes

29
Q

Advantage of A- PRF ?

A

better distribution of planets Leukocyte in the Fibrin alot

30
Q

protocol for I_PRF 7

A

injectable-PRF
500 RPM
3min
liquid consistence
longer 655 release profile

31

39
Q

Application al PRF in par ontology?

A

gingivalrecession,furcationdefects,regenerativeparodontological treatments

40
Q

After extraction impacted 3rd molar &
complicated healing? How PRF helps us?

A
41
Q

PRF in MRONJ:

A

medication -related osteonecrosis of jaw
can happen spontaneous or after intervention.

42
Q

PRF in MRONJ: 2

A

With the application more than 80% succesrate could be reach

Effects: formation of a fibrin network, adhesion of leukocytes and platelets, slow growth factor release, thereby increasing the regeneration tendency of soft and hard tissues

43
Q

PRF in cystectomy; after Removal cyst wall, we should do?

A

fill bone cavity with PRF

44
Q

what if we fill bone cavity by PRF
after cystectomy

A

y
- Formation fibrin mesh (then) stabilize blood
clot (then) helps bone regeneration.

45
Q

PRF in cystotomy (tos)

A

improve QOL
faster Regeneration

46
Q

PRF in Endodontics involve:

A
  • Apexifi cation
  • Direct pulp capping
47
Q

Direct pulp raping vs PRF?

A

PRF enhance: immun Response
increase dentin oogenesis
mineralization by slow release al growth
factor

48
Q

Best result of Direct pulp capping is use
of PRF and … together.

A

Mta

49
Q

MTA in Direct pulp capping increase…?

A

odontoblast differentiation

50
Q

pulp capping success depends on?

A

technique
material
tissue reaction

51
Q

Apexifi cation definition?

A

closing Apical foramen with medication.
usually calcium. hydroxide stakes 6 month.

52
Q

How result angiogenesis? (in Apexifi cation)

A

MTA + PRF + VEGF

53
Q

Apexification:
medication like (?)
after 6 month and several visit we see (?)

A

calcium-hydroxide
Apical barrier

54
Q

Apexification
medication like MTA
after How many visit we can see Apical plug

A

(2 visit)
(Apical plug) (not barrier)
