Which instrument is typically used to measure pocket depths during a periodontal exam?

The instrument commonly used to measure pocket depths during a periodontal exam is the periodontal probe. This specialized tool is designed with a calibrated measuring tip that allows the dental professional to accurately assess the depth of the gingival sulcus or periodontal pockets surrounding each tooth. Pocket depth measurements are crucial for diagnosing the severity of periodontal disease, as they provide insight into the attachment level of the gums to the teeth and the overall health of the periodontal tissues.

Periodontal probes come in various designs, often featuring markings that allow for easy reading of the depth measurements in millimeters. By inserting the probe gently into the sulcus and measuring the distance to the base of the pocket, clinicians can identify early signs of gum disease as well as monitor progression or improvement over time.

In contrast, other instruments like explorers are primarily used for detecting caries and surface irregularities, scalers are intended for the removal of calculus and plaque from tooth surfaces, and suction devices are utilized for maintaining a clear working field by removing saliva and debris during dental procedures. These tools have distinct purposes and are not suitable for measuring pocket depths.
