How is "periodontal probing" defined in dental practice?

Periodontal probing is defined as a technique used to measure the depths of the gum pockets surrounding teeth. This process involves the use of a periodontal probe, which is a calibrated instrument inserted into the sulcus or pocket between the teeth and the gums to determine how far the probe can be inserted before encountering resistance at the bottom of the pocket.

The measurement of pocket depth is crucial in assessing the health of the periodontal tissues and determining the presence of periodontal disease. Healthy gums typically have pocket depths of 1 to 3 millimeters, while deeper pockets can indicate gingivitis or periodontitis, conditions that may require further intervention.

This technique is vital for creating treatment plans, monitoring periodontal health over time, and understanding the progression of periodontal diseases.
