Which PSR code indicates bleeding on probing after gentle probing, with no calculus or defective margins; pockets ≤3.5 mm?

Which PSR code indicates bleeding on probing after gentle probing, with no calculus or defective margins; pockets ≤3.5 mm?

• A. Code 0
• B. Code 1 indicates bleeding on probing after gentle probing, with no calculus or defective margins; pockets ≤3.5 mm.
• C. Code 2
• D. Code 3

Answer: (B)

Bleeding on probing without calculus or defective margins, with pockets 3.5 mm or less, is described in PSR as code 1. This reflects early gingival inflammation detected by bleeding on probing while the tissue shows no signs of calculus or margin defects and probing depths remain shallow. If there were calculus or defective margins, or if pocket depths were deeper (beyond 3.5 mm), a higher PSR code would be used. Since the scenario specifies BOP, no calculus/defects, and shallow pockets, the match is code 1.
