Which term describes the depth of a periodontal pocket measured with a probe?

• A. Gingival recession
• B. Sulcus depth
• C. Clinical attachment loss
• D. Probing depth

Answer: (D)

Probing depth is the distance from the gingival margin to the base of the periodontal pocket, measured with a calibrated periodontal probe in millimeters. This measurement specifically reflects how deep the pocket extends along the tooth surface and is the standard way clinicians gauge disease severity and progression. Gingival recession describes how far the gingival margin has moved apically relative to the cementoenamel junction, which affects root exposure but doesn't measure pocket depth. Sulcus depth refers to the depth of a healthy gingival sulcus; in disease, the term we use for the pocket depth is probing depth rather than sulcus depth. Clinical attachment loss combines both recession and probing depth to indicate how much support has been lost around the tooth, but it is not the direct measurement of pocket depth itself. Therefore, the depth of a periodontal pocket measured with a probe is probing depth.
