Answer 7

gingival enlargement

Question 8

when the CEJ is covered by JE, this condition is known as _________.

Answer 8

gingivitis

Question 9

periodontitis occurs when JE migrates in what direction?

Answer 9

apically

Question 10

T/F: viable epithelium is not necessary for pocket formation

Answer 10

FALSE: it is necessary

Question 11

shape of interdental papilla depends on _______, ________ and _________.

Answer 11

contact relationships between adj teeth, width of approximal tooth surfaces, course of CEJ

Question 12

The concavity seen in contact areas of premolar and molar region

Answer 12

col

Question 13

the col is consists of _________ epithelium.

Answer 13

non-keratinized

Question 14

Where in the interdental papilla is the most disease susceptible?

Answer 14

col

Question 15

The ________ and __________ of the contact area determine probe angulations in posterior teeth.

Answer 15

position and dimensions

Question 16

proper probing position and angulation

Answer 16

1) find interproximal contact 2) use contact as guide to insert probe 3) open angulation by 10 degrees toward buccal

Question 17

T/F: Regarding gingival phenotype, narrow gingiva has the same resistance to AL as wide gingiva.

Answer 17

True

Question 18

thin phenotype has _________ recession, _________ vulnerable to trauma, ________ inflammation and a _________ favorable tx outcome.

Answer 18

increased, more, more, less

Question 19

When would you recommend gingival grafts?

Answer 19

1) when recession causes symptoms 2) subgingival restoration on thin phenotype 3) pre-ortho therapy

Question 20

What determines gingival epithelial characteristics?

Answer 20

connective tissue

Question 21

What are 2 examples of early grafting procedures?

Answer 21

1) free gingival grafts 2) coronally advanced flaps

Question 22

What type of grafting procedure is used today?

Answer 22

connective tissue graft, since CT determines epithelial prototype

Question 23

In necrotizing ulcerative periodontitis (NUP) there is ______ pocketing because ____________. Bone is exposed.

Answer 23

no pocketing, JE cells die

Question 24

the distance from the CEJ or crown margin to alveolar crest must be ____mm to keep proper biologic width

Answer 24

2mm

Question 25

guided tissue regeneration principle

Answer 25

epithelium grows faster than bone or connective tissue. epithelial exclusion will allow selective growth of these cells

Question 26

What are barrier membranes used for?

Answer 26

GTR collagen membrane
