What is the maximum depth of a clinically normal gingival sulcus?

• A. 5 mm
• B. 2 mm
• C. 4 mm
• D. 3 mm

Answer: (D)

The maximum depth of a clinically normal gingival sulcus is typically around 3 mm. This measurement reflects a healthy state where the attachment of the epithelium at the base of the sulcus remains intact, and there is no evidence ofPeriodontal disease or inflammation.

In a healthy person, the gingival sulcus is a natural space between the tooth and the surrounding gingival tissue, and its depth can vary slightly among individuals. However, a depth of 3 mm or less is generally accepted as a standard for periodontal health. Depths greater than this may indicate the presence of inflammation or the potential for periodontal disease, which would necessitate further evaluation and management.

Understanding that a clinically normal sulcus typically does not exceed this depth is crucial for dental practitioners, as it serves as a baseline for identifying periodontal status and guiding treatment decisions in their patients.
