Study Notes
Probing Depth
- The probing depth is the distance from the gingival margin to the bottom of the pocket.
- It is measured using a periodontal probe with a standardized tip diameter (0.4mm–0.5mm).
- A probing depth of 4mm or more indicates a periodontal pocket.
Limitations of Periodontal Probing
- The probe needs to be walked across the sulcus to ensure no pockets are missed.
- Bone levels vary in a small space, which can affect probing readings.
- Probing depth alone does not accurately reflect the loss of periodontal support.
6 Point Pocket Chart
- The six points refer to the buccal and lingual surfaces of a tooth, divided into six sections.
- The probing depth is recorded for each of the six points on a tooth.
- The walking stroke technique is used to ensure that all pockets are documented.
Free Gingival Margin
- The free gingival margin is the edge of the gingiva that surrounds the tooth.
- The location of the free gingival margin relative to the cementoenamel junction (CEJ) is important for periodontal assessment.
- A negative number indicates that the gingival margin covers the CEJ; a positive number indicates recession.
Clinical Attachment Levels
- The clinical attachment level (CAL) is a measurement of the true periodontal support around a tooth.
- It is calculated by adding the probing depth to the location of the gingival margin relative to the CEJ.
- CAL helps distinguish between gingivitis (inflammation without attachment loss) and periodontitis (inflammation with attachment loss).
Calculating CAL
- To calculate CAL, you need the probing depth and the level of the gingival margin.
- If the gingival margin is at the natural level, the CAL is equal to the probing depth.
- If there is recession, add the level of the gingival margin to the probing depth.
- If the gingival margin covers the CEJ, subtract the level of the gingival margin from the probing depth.
