Flashcards in Perio Ch 19 & 20 Deck (53):
1

What is the leading cause of dental malpractice claims?

Failure to diagnose periodontal disease

2

When is the periodontal assessment is complete?

Until all information gathered has been accurately recorded in the patient chart.

3

What are the 2 types of assessment?

Periodontal screening

Comprehensive periodontal assessment

4

Results of the periodontal screening and recording into 2 categories?

Periodontal health or gingivitis

Periodontitis

5

Techniques using a PSR screening exam include...

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

6

Code 0 PSR screening

Market is completely visible, no calculus, no bleeding

7

Code 1 PSR screening

Marker is completely visible, no calculus, bleeding

8

Code 2 PSR screening

Marker is completely visible, calculus, defective margins

9

Code 3 PSR screening

Marker is partially visible

10

Code 4 PSR screening

Marker is not visible

11

* indicates what on PSR screening?

A mucogingival defect

Ex:
Furcation involvement
Mobility
Mucogingival problems
Recession

12

Scoring of PSR screening

Assign the code in each sextant that is the most advanced periodontal findings on any tooth in the sextant.

13

Patient with low PSR scores in all sextants are

Considered periodontal pay healthy

No need for further periodontal assessment

14

Patients with 2 code 3 scores or one code 4 score warrants what?

A complete periodontal assessment

15

What is one of the most important functions performed by the clinician?

Clinical periodontal assessment

16

What is a comprehensive periodontal assessment?

An intensive clinical periodontal assessment used to gather information about the periodontium

17

What does BOP represent?

Bleeding from ulcerated soft tissue wall of periodontal pocket

Pressure should be between 10-20g of pressure

18

What is it called when it's a clear serous fluid?

Supperation

19

What is it called when fluid isn't clear and there's pus?

Exudate

20

FGM is slightly coronal to the CEJ means?

Normal position

21

FGM significantly coronal to the CEJ means?

Gingival enlargement

22

FGM apical to the CEJ means

Gingival margin

23

Class 1 recession means

Recession isolated on the facial surface

Fills embrasures

Does not extend to the mucogingival line

24

Class II recession means

Recession isolated to the facial surface

Fills embrasures

Does extend beyond the mucogingival line

25

Class III recession means

Recession extends beyond the facial surface

Does not fill embrasures

Does extend beyond the mucogingival line

26

Class IV recession means

Loss of hard and soft tissues around entire tooth!

Open interdental papilla

27

Horizontal tooth mobility

Movement of a foot in the facial to lingual direction

28

Vertical mobility is

The movement of a tooth up and down in the socket

29

Mobility rate scale- Class I

Up to 1mm in any direction

30

Mobility rating scale Class II

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

31

Mobility rating scale Class III

Facial- lingual movement and is depressible in the socket

32

Fremitus rating scale

N

Normal (without movement)

33

Fremitus rating scale

+

Only slight palpable movement

34

Fremitus rating scale

++

Clearly palpable but barely visible movement

35

Fremitus rating scale

+++

Movement clearly visible

36

Furcation classification

Class I

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

37

Furcation classification

Class II

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

38

Furcation classification

Class III

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

39

Furcation classification

Class IV

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

40

What is an inadequate attached gingiva level?

41

How do you calculate the width of the attached gingiva?

Measure the pocket depth

Measure the total width of the gingiva

Subtract pocket depth from total width

42

Difference in probing depths vs CAL

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

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

Loss of attachment

44

When the gingival margin is ____, no calculations are needed

Slightly coronal to or at the level of the CEJ

Probing depth=CAL

45

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

Less

46

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

CAL will be ___\ than the pocket depth

Greater

CAL= visible recession + pocket depth

47

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

0

48

Notations for the free gingival margin significantly covering the CEJ

-

49

Notation that the free gingival margin is apical to the CEJ

+

50

Interseptal bone changes

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

51

Triangulation

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

52

Crestal irregularities

Fuzziness in crest of interdental bone

53

Which arch is Furcation easier to see on?

Mandibular
