How should you record each zone?

• A. By taking the deepest measurement in that zone
• B. By recording the shallowest measurement
• C. By averaging measurements in that zone
• D. By recording the first measurement

Answer: (A)

Recording the deepest probing depth in each zone reflects how PSR codes are determined: the code for a zone is driven by the most apical (deepest) pocket found there. This approach ensures you don’t miss a advanced pocket in that area and provides a clear trigger for further evaluation or treatment planning. If you recorded the shallowest depth, or an average, you could underestimate the level of disease; recording the first measurement is arbitrary and could bias the result. By capturing the deepest measurement, you accurately represent the zone’s periodontal status.
