    Study Notes

    Probing Depth

    • Probing depth is the distance from the gingival margin to the bottom of the pocket.
    • Measured with a periodontal probe with a standardised tip diameter (0.4mm-0.5mm).
    • Healthy sulcus is 1–3mm, unhealthy is 4mm+.

    Six Point Pocket Chart

    • Assesses periodontal health pre-treatment.
    • Used to calculate probing depth around the tooth at six points.
    • Points include: Distobuccal, Buccal, Mesiobuccal, Distolingual, Lingual, Mesiolingual.
    • Deepest reading recorded for each site.

    Limitations of Probing

    • Can be affected by factors like inflammation, recession, and bleeding.
    • Six point charting can overestimate pocket depth due to false pocketing.

    Free Gingival Margin

    • The level of the free gingival margin can be:
      • Normal: slightly coronal to CEJ (0).
      • Overgrown: significantly covers CEJ (-).
      • Recession: apical to CEJ (+).
    • Overgrowth can be caused by medication, leading to false pocketing.

    Clinical Attachment Levels (CAL)

    • Measure of true periodontal support around a tooth.
    • Provides an estimate of periodontal stability and loss of support for a tooth.
    • Calculated using probing depth and gingival margin level.
    • Critical for distinguishing between gingivitis and periodontitis.
      • Inflammation with no attachment loss - gingivitis.
      • Inflammation with attachment loss - periodontitis.

    Calculating CAL

    • Normal level: CAL = Probing depth + Gingival margin level (0).
    • Recession: CAL = Probing Depth - Gingival margin level (+).
    • Overgrowth: CAL = Probing depth + Gingival margin level (-).
