Probe depth is 3mm, recession is 3mm. What is the CAL?

  1. 0 m
  2. 3mm
  3. 6mm
  4. 9mm

 Answer: C. 6mm

Clinical attachment level (or loss, CAL) is a more accurate indicator of the periodontal support around a tooth than probing depth alone. CAL is measured from a fixed point on the tooth that does not change, the CEJ.

Two measures are needed: gingival margin to the CEJ, and probing depth.

In recession: gingival margin to the CEJ + probing depth (add).

In tissue overgrowth: gingival margin to the CEJ - probing depth (subtract). In this case, recession is present, therefore add probe depth (3mm) to recession (3mm) = 6mm.
