Q

What are the steps to determine perio dx?

A
  1. initial overview- screen the xray PD tooth loss and put them into 1-2 or 3-4 stage
  2. Fine tune the state: look closly at the max CAL/BL determine if BL is H or V, perio tooth loss, complexity including furcation grade, PDs, occlusion, need for extensive multidisiplinary tx. Start at B then judge from there.
  3. Determine grade: hx of perio, risk factors and the ability to control them, response to tx, compliance with recs, and their systemic health factors

77
Q

Explain the concepts of repair and regeneration?

A

Repair:
Healing of a wound tissue that does not fully restore the architecture or the function of part of the long junctional epithelium

Regeneration:

Q

In term of regeneration, what does “new attachment” and “reattachment” mean and what is the difference?

A

new attachment: union of ET and/or CT with a previously disease rt surface

Reattachement: reunion of ET and/or CT with rt surfaces and bone after incision or injury

One is diseased and other is not
Think flap reflection for healthy teeth for gingivectomy= reattachment.

79
Q

What is guided tissue regeneration?
What is used to achieve regeneration?

A

Attempt to regenerate lost perio structure through differential tissue responses

Bone graft and barrier are used to facilitate GTR

80
Q

Why is a barrier used in GTR?

A

retard apical migration of ET and exclude CT from the root or existing bone surface in the belief that the interfere with regeneration.
