What is the primary purpose of a periodontal probe?

The primary purpose of a periodontal probe is to assess sulcus depth. This clinical tool is specifically designed to measure the depth of the periodontal pockets that surround each tooth. By inserting the probe into the sulcus (the space between the tooth and the gum), dental professionals can determine the level of attachment and identify any periodontal disease potential. The measurements taken help in diagnosing the severity of periodontal issues and creating effective treatment plans.

The periodontal probe can also provide insight into the health of the surrounding gum tissue, which is crucial for evaluating the overall condition of a patient's periodontal health. However, the key function remains the measurement of sulcus depth, as this directly informs the presence of gingivitis or periodontitis. The accurate assessment of this depth is foundational in periodontal diagnostics and subsequent treatment decisions.
