Code 4 in PSR indicates pocket depths?

Code 4 in PSR indicates pocket depths?

• A. Pockets 4-5 mm
• B. Pockets ≤3.5 mm
• C. Bleeding on probing
• D. Pockets ≥6 mm

Answer: (D)

In PSR, the code reflects the deepest probing depth found in a sextant, and a code of four signals pockets six millimeters or more. This threshold indicates a significant pocket that warrants a full periodontal examination and more comprehensive treatment planning, rather than just routine monitoring. Pocket depths of 4–5 mm correspond to the next lower code, while shallower depths (0–3.5 mm) are associated with codes indicating healthy tissues or minor concerns, and bleeding on probing alone points to early gingival changes rather than deep pocketing. So, pockets ≥6 mm best match the code for code four.
