What is recorded in each PSR sextant box?

• A. The Highest Code
• B. The Lowest Code
• C. The Average Code
• D. The Sum Of Codes

Answer: (A)

In PSR, you summarize the health of each sextant with a single code by recording the most severe finding seen in that sextant. The code scale runs from 0 to 4, reflecting increasing levels of periodontal involvement, and the number placed in the sextant box is the highest code observed among the teeth in that sextant. This approach keeps the screening focused on the worst condition in each area, which helps determine if further evaluation or referral is needed. Recording the lowest, an average, or a sum would not reliably indicate the true severity in that sextant, potentially underestimating disease. So, the correct practice is to record the highest code observed in each sextant box.
