What was the highest probing depth measured in this patient?

• A. 5 mm
• B. 3 mm
• C. 2 mm
• D. 7 mm

Answer: (A)

Probing depth reflects how deep the gum pockets are around a tooth, measured with a periodontal probe to gauge periodontal health. Normal depths are about 1–3 mm; depths of 4–5 mm indicate pocketing, and larger depths suggest more advanced involvement. In this patient, the greatest depth recorded was five millimeters, which is why the highest probing depth is five millimeters. The other options are shallower (two or three millimeters) or deeper than what was observed (a seven millimeter depth would indicate more severe pocketing than what was measured).
