Charting, Examination & Probing Flashcards
What 7 parameters must be charted for each tooth?
- Plaque/Calculus index
- Gingivitis index
- Pocket depth (PPD)
- Gingival recession
- Furcation
- Mobility
- Periodontal Attachment Level (PAL)
A plaque index which has a thin film along the gingival margin is a score ______
1
A plaque index which has heavy and abundant soft material in sulcus is a score ______
3
Describe the levels of Calculus Index from 0-3
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
What does a Gingivitis Index of 2 mean specifically?
Established gingivitis. Edema, beginning of inflammation, no pockets, subgingival plaque, bleeds on gentle probing
What is the difference between GI2 and GI3?
GI3 includes pockets and bleeds spontaneously
When charting pockets, where does the pocket depth go?
Around the tooth, exactly where the pocket was found
True or false: When measuring pockets, it is best to measure only one side of each tooth.
False. It is best to measure 4-6 spots around each tooth
At what length (mm) is considered a significant or abnormal pocket?
Dogs: >3
Cats: >1
When charting gingival recession, why do we add 1-2 mm to the pocket depth?
To account for the fact that the NORMAL free gingival margin is 1-2mm further down on the crown than the CEJ
What is furcation?
Bone loss on the part of the tooth where two or more roots meet
To measure furcation, what 2 tools do you need?
Probe and radiographs
Stage 2 Furcation means:
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
What is the difference between Stage 2 and Stage 3 Furcation?
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
A mobility index of 1 means:
Slight tooth mobility, 0.2mm-0.5mm laterally, NO vertical movement
A mobility index of 3 means:
Marked tooth mobility, more than 1mm laterally or vertically - needs to be extracted
Why is the classification of periodontal disease so important?
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
What does a Periodontal Disease Index of PD1 mean specifically?
Gingivitis only with no attachment loss.
What is the charting code for Epuils?
EP
What is the charting code for Furcation?
F1, F2, F3, etc
What does the charting code FX mean?
fractured tooth
What does the charting code GR mean?
gingival recession
What is the charting code for Resorptive Lesion?
RL
What does the charting code X mean?
Extracted
How do you chart missing teeth?
Circle the tooth
What does the charting code XS mean? What about XSS?
XS - extraction with sectioning, non-surgical
XSS - surgical extraction
How would you chart a fractured tooth?
Draw a line on the Buccal row of the chart, on the tooth where the fracture is. Write “FX” next to the line
Tooth Resorption (TR) can be broken into 3 subcategories. What are they?
TR4a - crown and root equally effected
TR4b - crown is more severely affected then the root
TR4c - root is more severely affected then the crown
What is an Epulis? How would we chart this?
Benign gingival tumour. Write OM/EPF and size
