Which statement is true about using probing for periodontal assessment?

• A. Probing helps determine pocket depths for planning treatment
• B. Probing is not used for treatment planning
• C. Probing should only be used to measure recession
• D. Probing can only be performed on permanent teeth

Answer: (A)

Probing provides essential data for planning periodontal treatment. By gently inserting a calibrated probe into the gingival sulcus or pocket and measuring depth in millimeters at multiple sites per tooth, you map out how deep the pockets are. These pocket depths reveal the severity and distribution of periodontitis and help decide what kind of therapy is needed—non-surgical cleaning, surgical intervention, or maintenance intervals.

Pocket depth data is also used with any gingival recession to determine clinical attachment level, giving a fuller picture of how much support a tooth has lost. Additionally, bleeding on probing can indicate active inflammation, influencing prognosis and follow-up, though the depth measurement itself is the core factor for planning.

Probing isn’t limited to permanent teeth; it’s applicable to primary teeth as well, and it isn’t used only to measure recession or only for treatment planning. The statement that probing helps determine pocket depths for planning treatment best captures its primary purpose in periodontal assessment.
