What is the primary purpose of PSR?

• A. To measure individual tooth mobility
• B. To determine the need for a comprehensive periodontal exam
• C. To replace full mouth periodontal charting
• D. To assess caries risk

Answer: (B)

Periodontal Screening and Recording is a quick chairside screening tool designed to flag which patients need a full periodontal examination. By probing each sextant with a specialized PSR probe and recording codes, clinicians identify areas that may indicate periodontal problems and therefore require comprehensive charting and evaluation. This triage function is its main purpose: to determine who needs a full periodontal exam rather than to measure tooth mobility, assess caries risk, or replace full mouth charting. So the primary role is to indicate the need for a complete periodontal assessment.
