What is the clinical attachment level (CAL) for Stage II periodontitis?

In the context of periodontal disease classification, Stage II periodontitis is characterized by a clinical attachment level (CAL) of 3 to 4 mm. This stage represents a moderate level of disease progression where there is noticeable loss of attachment, typically accompanied by pockets that are deeper than in earlier stages.

The importance of understanding CAL in the diagnosis and treatment planning of periodontitis lies in its role as an indicator of periodontal stability versus disease severity. A CAL of 3 to 4 mm suggests that the periodontitis has progressed beyond the gingivitis stage, indicating more significant tissue destruction and requiring appropriate intervention to prevent further deterioration of periodontal health.

This classification aids dental professionals in tracking the progression of periodontal diseases and tailoring treatment accordingly, emphasizing the need for early diagnosis and effective management strategies. Understanding these levels helps in educating patients about their periodontal health and the potential implications for their overall oral hygiene practices.
