Q

What happens in haemostasis part of healing?

A

Capillary damage = blood clot

Blood clot = protect exposed tissue and matrix for cell migration

Q

Local factors which affecting healing?

A 
Infection
Poor blood supply
Foreign body
Movement 
Ionising radiation
Type/size and location injury
24
Q

Why can movement affect healing?

A

Cause lack of stability graft - compromised fibrin clot

25
Q

What are systemic factors which affect healing?

A 
Age
Poor nutrition 
Hormones - e.g corticosteroids
Smoking
Uncontrolled diabetes 
Haematological abnormalities
26
Q

What is healing by primary intention?

A

When edges of wound are approximated at surgical site

Not much loss tissue/cells

27
Q

What is healing by secondary intention?

A

Wound not approximated, may have extensive loss of tissue = open w/ large tissue defect

28
Q

How does wound heal by secondary intention?

A

Granulation tissue from bottom up w/ epithelial cover

29
Q

Adv prei surgeyr?

A

Improved access and visualisation

Improved aesthetic - alter position gingival margin

30
Q

How long does healing following curettage take?

A

Restoration and epithelialisation begins 2-3 days and completed 7-10 days

Pocket epithelium removed allowed cells populate root surface

31
Q

What does curettage involve?

A

Scraping inner epithelial lining, epithelial attachment and underlying CT - remove inflammed soft tissue

32
Q

How does wound of gingvectomy heal?

A

Secondary intention

33
Q

How long does it take for gingivectomy wound to seal?

A

Complete = 6 weeks

34
Q

What a 4 stages of pedicle flap healing?

A

Adaptation
Proliferation
Attachement
Maturation

35
Q

How long to reach maturation stage of pedicle flap healing?

A

2-3 months

36
Q

What does survival of free tissue graft depend on?

A

Diffusion of products and oxygen through tissue plasma - graft doesn’t have own blood supply

37
Q

Phases of healing of free tissue graft?

A

Initial phase
Revascularisation
Tissue maturation

38
Q

How does a free graft vascularise?

A

Anastomses established between blood vessel of recipient bed and those in grafted tissue
Capillary proliferation
Fibrous union between graft and tissue bed

39
Q

How does successful healing of free graft rely on?

A

Close adaptation - metabolic products shorter distance diffuse, shorter distance cellular migration, lack mobility in graft

40
Q

3 main types bone regeneration materials?

A

Osseoconductive
Osseoinductive
Osseoproliferative

41
Q

Examples regenerative procedures?

A

GTR

Enamel matrix derivatives

42
Q

What is osseoproliferative regeneration?

A

New bone formed by bone forming cells contained in graft

43
Q

What is osseoconductive regeneration?

A

Graft acts as passive scaffold for adjacent host bone cells

44
Q

What is osseoinductive regeneration?

A

Bone formation induced in surrounding soft tissue via bone inducing substance

45
Q

Aim GTR?

A

Selectively guide tissue regeneration in periodontium

46
Q

What does GTR involve?

A

Placing physical barrier to prevent apical migration of epithelium and CT along root surface

47
Q

How can healing truly be assessed?

A

Histologically - impractical

48
Q

How measure perio healing clinically?

A

Probing - pocket depth
Radiograph - bony infill
Bleeding index

49
Q

Signs clinical success following debridement?

A 
Decreased inflammation
Reduced BOP
Decreased PD
Increase attachment 
Elimination poss
No increase mobility
Improved tissue contour 
Stabilisation bone levels
50
Q

What are clinical signs of success following root coverage procedure?

A

Marginal tissue reach CEJ
Clinical attachement
Sulcus depth 2mm of less
Absent BOP

51
Q

Complication may occur during periodontal tx?

A

Pain, bleeding, exposed apex, damage flap

Inadequate anaesthesia

52
Q

Complications may occur after perio tx?

A 
Pain
Bleeding
Sensitivity
Infection
Swelling 
Dysasthessia
Failure graft
53
Q

Long-term complication perio tx?

A

Recession
Sensitivitt
Poor aesthetic
Altered sensation

54
Q

What are pt factors that can produce variable outcome?

A

OHI
Smoking
General health/MH

55
Q

What are defect characteristics which can produce variable outcomes?

A

Defect width
Amount attachment loss
Amount bone loss
Occlusal loads
