In PSR, if a sextant shows Code 2 due to calculus but no pocket depth >3.5 mm, what is the recommended next step?

• A. Emphasize plaque control and prophylaxis; continue routine monitoring; FMPE may be pursued if other signs arise.
• B. Proceed to full periodontal charting immediately.
• C. No action needed.
• D. Record Code 3 and wait for pocket development.

Answer: (A)

When a sextant is coded as Code 2, the key idea is that calculus or defective margins are present, but probing depths are shallow (not exceeding 3.5 mm). This points to local contributing factors rather than established periodontal destruction. The best next step is preventive management: reinforce plaque control with clear instructions, perform a professional prophylaxis to remove calculus if indicated, and schedule routine monitoring to see if the code changes with improved hygiene. If other signs appear later—such as bleeding on probing, deeper pockets, or other periodontal findings—a full-mouth periodontal examination can be pursued and treatment can be escalated. Skipping action isn’t appropriate, and upgrading to a higher code isn’t warranted yet when pocket depths remain ≤3.5 mm.
