Charting, Examination & Probing

Question 1

What 7 parameters must be charted for each tooth?

Answer 1

1. Plaque/Calculus index
2. Gingivitis index
3. Pocket depth (PPD)
4. Gingival recession
5. Furcation
6. Mobility
7. Periodontal Attachment Level (PAL)

Question 2

A plaque index which has a thin film along the gingival margin is a score ______

Answer 2

1

Question 3

A plaque index which has heavy and abundant soft material in sulcus is a score ______

Answer 3

3

Question 4

Describe the levels of Calculus Index from 0-3

Answer 4

0- None
1- Supragingival calculus extending only SLIGHTLY below free gingiva
2- Moderate amount of supra and sub gingival calculus, or sub gingival only
3- Abundant supra and sub gingival calculus

Question 5

What does a Gingivitis Index of 2 mean specifically?

Answer 5

Established gingivitis. Edema, beginning of inflammation, no pockets, subgingival plaque, bleeds on gentle probing

Question 6

What is the difference between GI2 and GI3?

Answer 6

GI3 includes pockets and bleeds spontaneously

Question 7

When charting pockets, where does the pocket depth go?

Answer 7

Around the tooth, exactly where the pocket was found

Question 8

True or false: When measuring pockets, it is best to measure only one side of each tooth.

Answer 8

False. It is best to measure 4-6 spots around each tooth

Question 9

At what length (mm) is considered a significant or abnormal pocket?

Answer 9

Dogs: >3
Cats: >1

Question 10

When charting gingival recession, why do we add 1-2 mm to the pocket depth?

Answer 10

To account for the fact that the NORMAL free gingival margin is 1-2mm further down on the crown than the CEJ

Question 11

What is furcation?

Answer 11

Bone loss on the part of the tooth where two or more roots meet

Question 12

To measure furcation, what 2 tools do you need?

Answer 12

Probe and radiographs

Question 13

Stage 2 Furcation means:

Answer 13

Probe extends more than half way under crown of a multi-rooted tooth with attachment loss, but not through and through. Alveolar bone appears less dense on radiograph

Question 14

What is the difference between Stage 2 and Stage 3 Furcation?

Answer 14

Stage 3 includes through and through probing from one side under the crown to the other. Stage 3 also has obvious bone loss on radiograph

Question 15

A mobility index of 1 means:

Answer 15

Slight tooth mobility, 0.2mm-0.5mm laterally, NO vertical movement

Question 16

A mobility index of 3 means:

Answer 16

Marked tooth mobility, more than 1mm laterally or vertically - needs to be extracted

Question 17

Why is the classification of periodontal disease so important?

Answer 17

The degree of severity of periodontal disease as it relates to a single tooth; a patient may have teeth that have different stages of disease

Question 18

What does a Periodontal Disease Index of PD1 mean specifically?

Answer 18

Gingivitis only with no attachment loss.

Question 19

What is the charting code for Epuils?

Answer 19

EP

Question 20

What is the charting code for Furcation?

Answer 20

F1, F2, F3, etc

Question 21

What does the charting code FX mean?

Answer 21

fractured tooth

Question 22

What does the charting code GR mean?

Answer 22

gingival recession

Question 23

What is the charting code for Resorptive Lesion?

Answer 23

RL

Question 24

What does the charting code X mean?

Answer 24

Extracted

Question 25

How do you chart missing teeth?

Answer 25

Circle the tooth

Question 26

What does the charting code XS mean? What about XSS?

Answer 26

XS - extraction with sectioning, non-surgical

XSS - surgical extraction

Question 27

How would you chart a fractured tooth?

Answer 27

Draw a line on the Buccal row of the chart, on the tooth where the fracture is. Write “FX” next to the line

Question 28

Tooth Resorption (TR) can be broken into 3 subcategories. What are they?

Answer 28

TR4a - crown and root equally effected
TR4b - crown is more severely affected then the root
TR4c - root is more severely affected then the crown

Question 29

What is an Epulis? How would we chart this?

Answer 29

Benign gingival tumour. Write OM/EPF and size
