Q

List the root changes hindering tissue attachment: (4)

A
  1. foreign body nature of exposed diseased root surfaces (presence of endotoxin)

A

Gingivectomy

35
Q

Gingival deformities are reshaped and reduced to create a normal and functional form. The incision creates an external bevel:

A

gingivoplasty

36

Q

Elimination of SUPRABONY pockets which can’t be adequately debrided without soft tissue removal would indicate:
