PSR codes 3 and 4 indicate what periodontal finding?

• A. Deeper pockets.
• B. Calculus presence.
• C. Healthy tissue.
• D. Implant status.

Answer: (A)

PSR uses the probe to gauge pocket depth in each sextant, and the code you assign reflects the worst finding in that sextant. Codes 3 and 4 specifically mark the presence of periodontal pockets, meaning depths that exceed the normal sulcus. A code around 3 indicates pockets roughly in the 3.5 to 5.5 mm range, while a code around 4 indicates pockets greater than about 5.5 mm (often with other signs like furcation involvement in multirooted teeth). Because these codes signal actual pocket formation rather than healthy tissue, calculus, or implant status, they point to deeper pockets as the periodontal finding.
