What best describes Code 2 in PSR?

• A. Code 1 indicates calculus.
• B. Code 3 indicates pockets 4-5 mm.
• C. Code 2 indicates presence of calculus or defective margins in the sextant, with pocket depths ≤3.5 mm.
• D. Code 4 indicates pockets ≥6 mm.

Answer: (C)

Code 2 in PSR means there’s calculus or defective margins in a sextant, with pocket depths up to 3.5 mm. This combination signals local factors that can be addressed without needing deeper pocket therapy yet—the calculus or margin defect is the issue, not advanced pocketing. So, you’d clean and smooth the margins or remove calculus and then recheck the sextant to see if the code improves. If the pockets stay shallow and the calculus/margins are resolved, you’d move toward a healthier code; if deeper pockets or other problems emerge, higher codes would be considered (4 mm to 5 mm pockets for Code 3, or 6 mm or more for Code 4). The other options describe different findings: bleeding on probing without calculus, or pockets that are deeper, which is why they don’t describe Code 2.
