Q

gingival enlargement results in ____ probe depths and may cause ___ pocketing

A

deeper probe depths

pseudo pocketing

20
Q

what is the major difference between gingivitis and periodontitis?

A

the junctional epithelium has not migrated apically in gingivitis

21
Q

T/F: gingivitis may persist for years without progressing to periodontitis

A

True

22
Q

5 supragingival fibers

A
  1. Alvelogingival
  2. Dentoperiosteal
  3. Circular
  4. Transseptal
  5. Dentogingival
23
Q

Describe the: color, papilla, bleeding, sulcus depths, JE, alveolar bone, and cementum during GINGIVITIS

A

red, papilla is bulbous or swollen, bleeding upon probing, probe depths greater than 3 mm, JE extends rete pegs down CT, Alveolar bone and cementum are normal

24
Q

during perio, can the JE be maintained?

A

yes, but you cannot move it back

25
Q

what do the supragingival fibers look like during perio

A

supragingival fiber bundles are fragments, but transseptal fibers regenerate continuously across the crest of bone

26
Q

what is the body’s reaction to injury or invasion by disease-producing organisms?

A

inflammation

27
Q

what happens to the bone height in perio?

A

reduction in bone height which can progress to tooth loss

28
Q

in health and gingivitis, the rest of the alveolar bone is ____ mm apical to the CEJ

A

1-2 mm

29
Q

two types of bone loss & which is more common

A

horizontal (more common) and vertical

30
Q

horizontal bone loss produces a ___ pocket.

A

suprabony (pocket is above the bone)

31
Q

vertical bone loss produces an _____ pocket

A

infrabony (pocket is below the bone)

32
Q

why does the inflammation spread through path of least resistance?

A

the PDL is an effective barrier (dense CT)

33
Q

what order are tissues destroyed when inflammation follows the CT sheaths in horizontal bone loss (4 steps)

A
  1. epithelium to CT
  2. supporting alveolar bone (cortical bone)
  3. alveolar bone proper (bundle bone)
  4. PDL fiber bundles
34
Q

what can weaken crestal fibers in Vertical bone loss

A

occlusal trauma

35
Q

what order are tissues destroyed when inflammation goes directly into the PDL space during vertical bone loss (5 steps)

A
  1. eptihelial to CT
  2. PDL fiber bundle
  3. Bundle bone
  4. Cancellous bone
  5. Cortical bone
36
Q

what is furcation involvement?

A

occurs on multirooted teeth when the perio infection invades the area between and around the roots

37
Q

T/F: a disease site must involve more than one surface of a tooth

A

False. it can involve only a single surface of a tooth

38
Q

what is the difference between an inactive and active disease site?

A

inactive site is stable with the attachment level of the JE remaining the same over time
active site shows continued apical migration of the JE over time

39
Q

T/F: a majority of adults have active pockets

A

False: most adults have inactive pockets

40
Q

2 types of periodontal pockets

A
  1. gingival pocket

2. periodontal pocket

41
Q

characteristics of gingival pocket

A
  1. no migration of the JE
  2. gingival enlargement which results in pseudo pocketing
  3. no destruction of the PDL fibers
42
Q

characteristics of periodontal pockets

A
  1. apical migration of JE
  2. PDL and gingival fibers are destroyed
  3. bone loss
43
Q

will you find recession in chronic gingivitis?

A

no

44
Q

T/F: calculus deposits are not the cause of periodontal disease

A

true, bacteria is the cause of perio disease

45
Q

if you have a one-wall intrabony defect, how many walls are remaining?

A

one
