Q

Techniques using a PSR screening exam include…

A

Using a WHO probe.

The WHO probe has a color coded band called a reference mark– located 3.5-5.5mm from the probe tip

Q

FGM apical to the CEJ means

A

Gingival margin

23
Q

Class 1 recession means

A

Recession isolated on the facial surface

Fills embrasures

Does not extend to the mucogingival line

24
Q

Class II recession means

A

Recession isolated to the facial surface

Fills embrasures

Does extend beyond the mucogingival line

25
Q

Class III recession means

A

Recession extends beyond the facial surface

Does not fill embrasures

Does extend beyond the mucogingival line

26
Q

Class IV recession means

A

Loss of hard and soft tissues around entire tooth!

Open interdental papilla

27
Q

Horizontal tooth mobility

A

Movement of a foot in the facial to lingual direction

28
Q

Vertical mobility is

A

The movement of a tooth up and down in the socket

29
Q

Mobility rate scale- Class I

A

Up to 1mm in any direction

30
Q

Mobility rating scale Class II

A

Greater than 1mm in any directions but not depressible in pocket

31
Q

Mobility rating scale Class III

A

Facial- lingual movement and is depressible in the socket

32
Q

Fremitus rating scale

N

A

Normal (without movement)

33
Q

Fremitus rating scale

+

A

Only slight palpable movement

34
Q

Fremitus rating scale

++

A

Clearly palpable but barely visible movement

35
Q

Fremitus rating scale

+++

A

Movement clearly visible

36
Q

Furcation classification

Class I

A

Curvature of concavity can be felt with the probe tip, the probe penetrates no more than 1mm

37
Q

Furcation classification

Class II

A

The probe tip penetrates into the Furcation greater than 1mm but does not pass through

38
Q

Furcation classification

Class III

A

The probe passes completely through the Furcation which is still covered by soft tissue

39
Q

Furcation classification

Class IV

A

Same as class III except entrance to Furcation is clinically visible bc of recession of the gingival margin

40
Q

What is an inadequate attached gingiva level?

A
41
Q

How do you calculate the width of the attached gingiva?

A

Measure the pocket depth

Measure the total width of the gingiva

Subtract pocket depth from total width

42
Q

Difference in probing depths vs CAL

A

Probing depths measured from gingival margin to the base of the sulcus

CAL is measured from the CEJ to the base of the sulcus

43
Q

What is a critical factor in distinguishing between gingivitis and periodontitis?

A

Loss of attachment

44
Q

When the gingival margin is ____, no calculations are needed

A

Slightly coronal to or at the level of the CEJ

Probing depth=CAL

45
Q

If the gingival margin is significantly coronal to the CEJ, CAL will be ____ than the pocket depth

A

Less

46
Q

When recession is present (the GM is apical to the CEJ)

CAL will be ___\ than the pocket depth

A

Greater

CAL= visible recession + pocket depth

47
Q

Notations for the free gingival margin slightly coronal to the CEJ?

A

0

48
Q

Notations for the free gingival margin significantly covering the CEJ

A

-

49
Q

Notation that the free gingival margin is apical to the CEJ

A

+

50
Q

Interseptal bone changes

A

Finger like radiolucent projections extending from the crestal bond into the interdental alveolar bone

51
Q

Triangulation

A

Widening of the PDL space caused by bone resorption. Also called funneling

52
Q

Crestal irregularities

A

Fuzziness in crest of interdental bone

53
Q

Which arch is Furcation easier to see on?

A

Mandibular
