Question

Probe depth is 7 mm, recession is 2 mm. What is the CAL?

A. 2 mm
B. 5 mm
C. 7 mm
D. 9 mm

Answer 1

The CAL, or Clinical Attachment Level, is 9 mm.

Step-by-step explanation:

The CAL, or Clinical Attachment Level, is a term used in dentistry to measure the distance between the gingival margin (the edge of the gum) and a fixed reference point on the tooth. In this case, the probe depth is 7 mm, which means the gum has receded 7 mm below the reference point. Additionally, the recession is 2 mm, which means the gum has receded 2 mm away from the tooth. To calculate the CAL, we add the probe depth and recession together. Therefore, the CAL in this case would be 7 mm + 2 mm = 9 mm.
