The primary instrument used to measure the depth of a periodontal pocket is the probe. A periodontal probe has a calibrated measuring tip that allows dental professionals to accurately assess the depth of the pockets around teeth. This measurement is critical for diagnosing and monitoring periodontal disease, as deeper pockets typically indicate more severe levels of disease and attachment loss. The probe is specifically designed for this purpose, with features that enable it to be gently inserted into the sulcus between the tooth and the gum without causing trauma, allowing for an accurate depth reading.

Other instruments mentioned serve different functions: an explorer is used to detect caries and irregularities on tooth surfaces, a scaler is designed for removing calculus from teeth, and forceps are primarily used for extracting teeth. Each of these tools has a distinct role within dental practice, but only the probe is focused on measuring periodontal pocket depth, which is crucial for periodontal assessments and treatment planning.
