What is the primary purpose of the periodontal probe?

1. Determine pocket depths

2. Assess tooth mobility

3. Evaluate gum color

4. Measure gingival recession

The correct answer is: Determine pocket depths

The primary purpose of the periodontal probe is to determine pocket depths. This instrument is specifically designed to measure the depth of the sulcus around each tooth, which provides valuable information about the health of the periodontal tissues. By assessing the pocket depths, dental professionals can diagnose the presence of periodontal disease, monitor disease progression, and plan appropriate treatment strategies. Regular evaluations of pocket depths are essential for maintaining optimal oral health, as deeper pockets often indicate a greater level of attachment loss and potential gum disease. Effective periodontal probing allows clinicians to gather critical data to inform treatment plans and track changes over time, making it a fundamental aspect of periodontal examination. The other choices involve different aspects of periodontal assessment. Tooth mobility evaluation and monitoring gum color or gingival recession, while important, do not primarily address the probing function specifically designed to gauge pocket depth.
