FPC 2 Exam 2 – Periodontal Screening And Recording (PSR) And Probing Practice Test

Which describes a limitation of PSR?

Takes significantly longer to perform than full exam Provides detailed tooth-by-tooth charts for maintenance Doesn't provide a tooth-by-tooth assessment for later comparison during maintenance Requires radiographs for all sextants

Correct Answer:

Doesn't provide a tooth-by-tooth assessment for later comparison during maintenance

Explanation:

PSR is a quick screening method that records a single code for each sextant rather than a full tooth-by-tooth chart. Because only sextant-wide data are captured, it doesn’t provide detailed pocket depths for individual teeth to track changes over time during maintenance. That limitation is precisely why this item describes PSR as not giving a tooth-by-tooth assessment for later comparison. In contrast, the other statements don’t fit: PSR is designed to be faster than a full exam, it does not produce detailed tooth-by-tooth charts, and radiographs are not required for PSR (though they may be used in the full assessment if indicated).
