NOT a criterion for PSR Code 2?

• A. PD Above 5.5 mm
• B. Bleeding
• C. Calculus
• D. PD Below 3.5 mm

Answer: (A)

In PSR, codes categorize a sextant based on pocket depth bands and signs like bleeding or calculus. Code 2 is used when there are shallow pockets up to 3.5 mm and there is additional sign such as calculus or defective margins, or bleeding on probing. This reflects some periodontal involvement without deeper pockets. Pockets deeper than 3.5 mm but up to 5.5 mm fall into Code 3, and pockets deeper than 5.5 mm fall into Code 4. Therefore, probing depths above 5.5 mm are not a criterion for Code 2; that finding corresponds to Code 4. Bleeding and calculus with shallow pockets, or defective margins, fit Code 2, which is why those options align with Code 2.
