27
Q

Col area

A

Below contact area
Depression on the proximal sides of teeth
Not usually keratinized
Most periodontal infections start here first
Harder to reach bacteria, colonizes quicker

28
Q

Periodontal Case types

A

1-4

29
Q

Perio case 1

A

Gingival disease: bleeding in a couple spots, healthy patient

30
Q

Perio case 2

A

Early Periodontitis, couple 4mm pockets in each quadrant

31
Q

Perio case 3

A

Moderate Periodontitis

32
Q

Perio case 4

A

Advanced Periodontitis

33
Q

When does bone loss usually occur?

A

5mm, usually 4mm is inflammation of the gums

34
Q

What happens if the bone is involved?

A

It goes straight to periodontitis which is irreversible

35
Q

What is the importance of perio probing?

A

Detection of initial bone loss (should be up at CEJ)
Diagnosis w/ radiographs
*Absolute must

36
Q

What are the different types of pockets?

A

Suprabony (Normal, Gingival, Periodontal)
Intrabony (periodontal)
Is the pocket depth below or above bone?

37
Q

Changes in alveolar bone height

Health

A

Crest of the alveolar bone is approx. 2 mm apical to the CEJ

38
Q

Changes in alveolar bone height

Disease

A

Crest of the alveolar bone is more than 2 mm apical to the CEJ
Anything less than 2mm is bone less/disease

39
Q

Classifications of Furcations

A

Bone loss happening b/w roots

1-4 all have some sort of bone loss/disease

40
Q

What is the clinical picture of health?

A

Pink, Firm, No bleeding

41
Q

What does a healthy sulcus consist of?

A

JE coronal to CEJ (high and healthy)
Supragingival fibers intact
Alveolar bone intact
PDL intact

42
Q

What is the clinical picture of gingivitis?

A

Red
Swollen
Bleeding is likely

43
Q

What does the gingival pocket look like (gingivitis)?

A

Supragingival fiber destruction
Alveolar bone intact
PDL intact
Still reversible @ this time

44
Q

What is the clinical picture of periodontitis?

A

Pink(chronic)purplish(acute/active)
Swollen or fibrotic
Bleeding entire time of probing

45
Q

What does a perio pocket consist of?

A 
JE on cementum
Fiber detruction
Alveolar bone destruction
PDL destruction
Motility
Can't restore but can maintain
46
Q

Development of Gingival and Perio infections

A

Initial, Early (reversible)

Established, Advanced Lesions (problem w/ the bone)

47
Q

Initial Lesion

A

2-4 days, usually can’t see

48
Q

Early Lesion

A

4-14 clinically visible, breakdown continues and neutrophils come in

49
Q

Established Lesion

A

Rolling, lost contours

50
Q

Advanced Lesions

A

Doesn’t bleed, chronic state of disease

51
Q

Factors involved in disease development

A

Etiologica, Predisposing, Contributing, Risk, Can be local or systemic

52
Q

Etiologic Factor

A

Cause of disease (bacteria, medications, biofilm, toxins)

53
Q

Predisposing Factor

A

Systemic problem (makes them more susceptible)

54
Q

Contributing Factor

A

Malalignment, poor diet, smoking (add to condition)

55
Q

Risk Factory

A

Age, Gender F>M, stress, race

56
Q

Local contributing factors in disease development

A

Bacterial plaque, Areas of Retention, Iatrogenic, mastication, Oral habits, Everyday habits, plaque control, systemic, Genetic predisposition, Effects of certain drugs

57
Q

Complication of pocket formation furcation and Mucogingival involvement
(Furcation covered by tissue)

A 
Difficult to clean
Accessibility limited
Increase bone loss
Infection/Abscess
Diseases progression increases, can spread
Ultimate loss of tooth
58
Q

Untreated decay

A

Root caries, not every cavities will arrest or go full blown

59
Q

Palatogingival groove

A

Where bacteria and calculus is usually missed

60
Q

Root Concavity

A

Have to flap up the tissue

61
Q

Food impaction

A

Sometimes the lingual side looks good whereas the buccal would be a challenge

62
Q

Bulky Crown

A

Need a good biological width in order to maintain healthy tissue
Some base metals are incompatible w/ tissue (roll, bleed, don’t lay down)

63
Q

Pregnancy Gingivitis

A

Goes away when not prego
Sensitive
Vicious cycle
Isn’t super common or rare

64
Q

Periodontitis and Down Syndrome

A

Physical ability compromised
Homecare isn’t good
Maligned
Dexterity (not very efficient)

65
Q

Gingival overgrowth

A

Certain medications cause this
Overgrown tissue
Can do surgery every couple of months

66
Q

Drug induced

A

More fibrotic
Dense tissues, not fluid filled
Heart problem medications result

67
Q

Associated w/ smoking

A

Stain itself isn’t a problem

Stain is sticky which attracts biofilm
