What does CAL stand for in periodontal assessment?

• A. Clinical attachment loss
• B. Calculated attachment level
• C. Cementum-attachment length
• D. Crown-to-attachment length

Answer: (A)

Clinical attachment loss measures how much periodontal support has been lost. It is defined as the distance from the cementoenamel junction (CEJ) to the base of the pocket. This makes it a meaningful, cumulative indicator of disease because it incorporates both pocket depth and any gingival recession. In practice, CAL can be thought of as probing depth plus the amount of recession (if recession is present); when the gingival margin is at the CEJ (no recession), CAL equals the probing depth. This is why CAL is used to stage severity and monitor progression over time. Other terms you might encounter aren’t standard in periodontal assessment: calculated attachment level, cementum-attachment length, and crown-to-attachment length. They don’t define the true attachment loss clinicians track.
