foreign body reactions (popcorn kernal, braces), genetic
21
Q

What type of category does pregnancy and gingivitis fall into?

A

plaque induced gingivitis

22
Q

What does epidemiology risk mean?

A

likelihood a person will get a disease

23
Q

What does epidemiology risk factor mean?

A

factor that puts them at a greater risk

24
Q

What MO’s cause Chronic PD?

A

Porphyromonas gingivalis
Tannerella forsythia
Treponema denticola
Aggregatibacter actinomycetemcomintans

25
Q

What MO’s cause Aggressive PD?

A

Aggregatibacter actinomycetemcomintans

Porphyromonas gingivalis

26
Q

What MO’s cause Necrotizing PD?

A

Prevotella intermedia
Spirochetes (invade CT)
Fusiform bacilli

27
Q

Describe tooth associated subgingival plaque

A 
densely adherent
G+ rods, cocci
facultative aerobes/anaerobes
remove by SRP (mechanical removal)
less virulent
28
Q

Describe tissue associated subgingival plaque

A 
loosely adherent
G- motile anaerobes
spirochetes
remove surgically
more virulent
29
Q

Microbial shift: Healthy to Gingivitis to Periodontitis?

A

G+ to G-
Cocci to Rods to Spirochetes
Non-motile to motile
Facultative to obligate anaerobes

30
Q

What is calculus?

A

calcified dental plaque

31
Q

What is calculus’ role?

A

increases surface area, density where plaque can accumulate and bacteria can concentrate

32
Q

Is calculus a primary or secondary role in PD?

A

secondary

33
Q

Factors that can cause calculus?

A

anatomical abnormalities - fluted root surfaces, enamel pearls
physical irritants - amalgam overhangs, restoration contours
habits - mouth breathing, incorrect tooth brushing
systemic disease

34
Q

Calculus attachments

A

pellicle
penetrate cementum
lock into surface irregularities
into depressions/concavities in roots (PREMOLAR roots)

35
Q

True/False Furcations and mutirooted teeth more prone to perio disease

A

True

36
Q

What cells first to invade into the pocket?

A

PMNs from leaky ulcerative gingival epithelium

37
Q

What do PMNs do?

A

phagocytize crap

38
Q

What’s second into pockets?

A

Mast cells

39
Q

What do Mast cells do in pocket?

A

release amines to increase vascular permeability

40
Q

What’s 3rd into pockets?

A

macrophage

41
Q

What does macrophage do in pockets?

A

present antigen to T-cells
