Chapter 14- Periodontal Surgery

Question 1

is indicated to control the progression of periodontal destruction and attachment loss when more conservative nonsurgical treatments are not sufficient.

Answer 1

Periodontal surgery

Question 2

involves techniques that intentionally cut into soft tissues to control disease or change the size and shape of tissues.

Answer 2

Periodotnal surgery

Question 3

The major benefit and indication for periodontal surgery is to

Answer 3

gain access to root surfaces for scaling and root planing.

Question 4

advantages of surgery:

Answer 4

• Improving access to periodontal abscesses
• Exposing root surfaces for restorative dentistry
• Altering the position of the gingival margin to improve patient esthetics

Question 5

A number of disadvantages and contraindications to periodontal surgery exist:

Answer 5

• Health status or age of the patient

- Specific limitations for each of the periodontal surgical procedures

Question 6

considerations must be made when periodontal surgical therapy is prescribed:

Answer 6

Probing pocket depth
Amount of bone loss
Importance of the tooth to function
Esthetics
Patient’s level of plaque biofilm control
Patient’s general health

Question 7

a deepened gingival sulcus with an infected root surface covered by an ulcerated epithelial surface with underlying inflamed connective tissue.

Answer 7

periodontal pocket

Question 8

the measurement from the crest of the gingival margin to the base of the pocket.

Answer 8

probing depth

Question 9

is measured from the cementoenamel junction to the base of the pocket.

Answer 9

attachment loss

Question 10

If the gingival margin is on the enamel surface of the crown, as in gingival hypertrophy, then the attachment loss is

Answer 10

less than the probing depth

Question 11

If the gingival margin is on the root surface, as when recession has occurred, then the attachment loss is

Answer 11

greater than the probing depth

Question 12

only the first step in identifying patients who may be helped by periodontal surgery.

Answer 12

The 5-mm guideline

Question 13

Usually, 1 to 2 mm of connective tissue attachment covered by epithelium is between the probing depth and the alveolar bone. This area must be considered when estimating the amount of attachment remaining on a periodontally involved tooth.

Answer 13

biologic width

Question 14

Bone loss caused by periodontal disease results in

Answer 14

osseous defects

Question 15

What happens when a osseous defect in the horizontal dimension occurs ?

Answer 15

bone resorption is equal on the mesial and distal surfaces of the teeth

Question 16

What happens when an osseous defect in the vertical dimension occurs ?

Answer 16

bone resorption is unequal around the teeth
