What mobility class was documented for the 65-year-old patient?

• A. Class 0
• B. Class 1
• C. Class 3
• D. Class 2

Answer: (D)

Mobility class is a way to quantify how much a tooth moves when you apply gentle pressure, reflecting how much periodontal support remains. The 65-year-old patient shows about 1 to 2 millimeters of horizontal movement, which fits the moderate category. That is why this is Class 2. It indicates some attachment loss and looseness, but not the greater than 2 mm movement with vertical displacement seen in Class 3, nor the minimal movement seen in Class 0 or Class 1.
