How do radiographs relate to PSR?

• A. They replace PSR findings.
• B. They support PSR findings by confirming bone loss and aiding interpretation of pocket depths; they complement the screening.
• C. They are not used with PSR.
• D. They are only for caries assessment.

Answer: (C)

Radiographs provide information about the supporting bone and periodontal structures that a probing exam alone can’t fully reveal. In PSR, the screening with a specialized probe quickly flags areas needing further attention, but radiographs are used to support those findings by confirming bone loss when it’s present and by helping interpret what pocket depths mean in the context of the surrounding bone and anatomy. They complement the screening, offering a fuller picture of periodontal health, rather than replacing the PSR examination. Also, radiographs aren’t limited to caries assessment; they’re valuable for detecting bone changes, furcation involvement, and other periodontal issues that influence diagnosis and treatment planning.
