Which statement describes PSR Code 2?

• A. Bleeding May Be Present
• B. Calculus May Be Present
• C. PD Below 3.5 mm
• D. All Of The Above

Answer: (D)

PSR Code 2 is used for a sextant where shallow probing depths are present, and calculus or defective margins may be detected, with bleeding on probing possibly occurring. In this code, the pocket depth is 3.5 mm or less, and you may also find calculus or defective margins, and you may see bleeding on probing. That means each of the statements can describe a Code 2 scenario: bleeding on probing may be present, calculus may be present, and probing depths are 3.5 mm or less. The phrasing “below 3.5 mm” is typically understood as within the 3.5 mm or less range. Therefore all of these aspects can describe Code 2, making the combined option the best choice. In PSR practice, this code flags a need for more detailed assessment and periodontal care planning, but is not itself a full diagnosis.
