Q

List the root changes hindering tissue attachment: (4)

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

33
Q

Removal of the connective and epithelial attachment circumferentially with a scalpel:

A

ENAP

34
Q

The excision of the soft tissue wall of the periodontal pocket, the incision forms an external bevel or surface that is exposed to the oral cavity:

A

gingivectomy

35
Q

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

A

gingivoplasty

36
Q

removal of the total piece:

A

-ectomy

37
Q

re-shaping the existing structure:

A

-plasty

38
Q

A pocket above the bone level:

A

suprabony pocket

39
Q

Elimination of SUPRABONY pockets which cannot be adequately debrided without tissue removal would indicate:

A

Gingivectomy

40
Q

Eliminatino of SUPRABONY pockets if the pocket wall is fibrous and firm and therefore will not shrink after non-surgical therapy would indicate:

A

Gingivectomy

41
Q

What procedure should be performed in the following scenario?

Suprabony pockets which can’t be adequately debrided without tissue removal:

A

gingivectomy

42
Q

What procedure should be performed in the following scenario?

Suprabony pockets if the pocket wall is fibrous and firm and therefore will not shrink after non-surgical therapy:

A

gingivectomy

43
Q

What procedure should be performed in the following scenario?

Needing access for restorative therapy in the presence of suprabony pockets:

A

gingivectomy

44
Q

What is the most common indication for gingivectomy?

A

45
Q

What procedure should be performed in the following scenario?

Patient presents with gingival enlargement due to taking dilantin:

A

gingivectomy

gingivectomy

48
Q

List the CONTRAindications for performing a gingivectomy:
