What probing depth range is typically considered healthy in a periodontal exam?

• A. 0-1 mm
• B. 1-3 mm
• C. 4-6 mm
• D. 7-8 mm

Answer: (B)

Healthy probing depths reflect a shallow sulcus, typically about 1 to 3 millimeters. This range indicates the gingival margin sits close to the crown with no substantial pocket formation, and often there is no bleeding on probing. Deeper measurements point toward pocket formation from periodontal inflammation and attachment loss: 4–6 millimeters suggests a shallow to moderate pocket, and 7–8 millimeters indicates a deep pocket with more advanced disease. A reading of 0–1 millimeter can occur with gingival recession or unusually tight tissue, but it isn’t the typical baseline for health. Remember that probing depth is just one piece; clinician should consider inflammation, bleeding on probing, and attachment levels to assess periodontal health accurately.
