Which instrument is specifically used to measure periodontal pockets?

The periodontal probe is the correct instrument for measuring periodontal pockets, which are essential for assessing the health of the gums and surrounding tissues. This instrument is designed with a slender, calibrated tip that allows dental professionals to gently insert it into the sulcus (the space between the tooth and surrounding gum tissue) and measure the depth of the pocket in millimeters. Accurate measurement of these pockets is crucial for diagnosing periodontal disease, as deeper pockets often indicate more severe cases and require different treatment approaches.

In contrast, while a dental explorer is used to detect caries (cavities) or irregularities on the tooth surface, it is not designed for measuring pocket depth. A scaler is specifically intended for the removal of calculus and plaque from the tooth surfaces but does not provide measurements of pocket depth. The handpiece is used primarily for various restorative procedures, such as drilling or polishing teeth, but is unrelated to periodontal assessments. Therefore, the periodontal probe stands out as the only instrument tailored for the specific function of measuring periodontal pocket depths.
