Q

What is Moderate Clinical Attachment Loss?

A

3 - 4 mm

17
Q

What is Severe Clinical Attachment Loss?

A

above 5 mm

18
Q

What is the etiology of ANUG?

A

Bacterial invasion (usually gram (-) spirochetes) in those who are immunocompromised

19
Q

What is CRP, what does it do

A

A. CRP is a typical acute-phase protein that opsonizes bacteria and facilitates complement fixation. This all helps in phagocytosis of bacteria
B. Synthesized in liver

20
Q

What are the 3 functions of leukocytes?

A
  1. Chemotaxis
  2. Phagocytosis
  3. Antigen processing and presentation
21
Q

What is the difference between a Monocyte and Macrophage?

A

Macrophages are monocytes in tissue

Monocytes are in the blood

22
Q

What is transendothelial migration?

A

Movement of leukocytes from blood stream into local tissues at inflammation site

23
Q

Stages of wound healing

A

A. 1-2 days: clot / Inflammation (epithelial cells migrate under clot) you have PNMs
B. 3-4 days: Proliferation (fibroblasts)
C. 7-21 days: Granulation (collagen peak)
D. 1 month (21-28 days) : Remodeling/ Bone formation
E. 6 months: Maturation

24
Q

What is the ledge and wedge technique?

A

A. Internal bevel gingivectomy not a true gingivectomy because it is not confine to the gingiva… partial thickness flap procedure.
B. Technique allows reflection of conventional flap and access to bone if needed

  • perpendicular inverse incision
  • perpendicular external
25
Q

How does Open Flap Debridement change Probing Depth?

A

You can expect 2 mm recession and
1.4 mm gain in CAL

  • Reduced PD
  • Some gain CAL
  • Heal long Junctional Epithelium (JE)
26
Q

Root trunk length in Maxillary Molar?

A

Maxillary:

a. Short= 3mm,
b. Medium= 4mm,
c. Long= 5+mm

27
Q

Root trunk length in Mandibular Molars?

A

a. Short= 2mm,
b. Medium= 3mm
c. Long= 4+mm

28
Q

Why is root truck length important in furcation involvement?

A

Longer root trunk means more attachment has to be lost before furcation invasion.

29
Q

How do you diagnose a furcation?

How accurate is the furcation arrow in detecting actually furcation invasions in maxillary molars?

A

Radiograph and Probe

a. Probe: Straight probe for vertical depth and curved probe for horizontal
b. Best way is BONE SOUNDING

Furcation arrow–> sensitivity was only 39%,
