What must be displayed in any dental office where radiography services are performed?

• A. The dentist's license copy.
• B. No display requirement.
• C. A dental assistant's certification as a dental radiographer.
• D. The business license display.

Answer: (C)

Credentialing and display rules for radiography in a dental office require posting the current dental radiographer certificate where radiographs are performed. This shows patients and staff that the person taking X-rays is properly trained and authorized to do so, supporting patient safety and regulatory compliance. The specific display of the radiographer’s certificate is the required item tied to radiography practice. A dentist’s license or business license is not the credential that must be displayed in relation to radiography, and there is a display requirement for radiographer certification, not for general licenses.
