PSR is described as a screening tool rather than a comprehensive measurement.

• A. True
• B. False
• C. Not specified
• D. Both true and false

Answer: (A)

This is true. PSR is a quick screening method designed to flag patients who need a full periodontal examination, not to provide detailed measurements. It uses a simplified probe to scan each sextant and assign codes that indicate whether there might be periodontal concerns. Because the aim is triage, it doesn’t yield the complete data of a comprehensive periodontal assessment—such as exact pocket depths, attachment levels, recession, furcation status, and mobility for every tooth. When a high-risk code is identified, a full, detailed periodontal charting is performed to obtain the full measurements. So the statement about PSR being a screening tool rather than a comprehensive measurement is correct.
