Which statement about shielding is incorrect during dental radiography?

• A. They reduce patient exposure.
• B. They must fit properly.
• C. They should be used depending on imaging goals, but must not interfere with imaging.
• D. They should always be used regardless of imaging goals.

Answer: (C)

Shielding lowers radiation to sensitive tissues and must be placed correctly so it covers the right area without gaps. The key idea is to use shielding whenever it won’t interfere with getting a clear, diagnostic image. The statement in question is not ideal because it frames shielding as something you adjust based on imaging goals. In practice, shielding should be used to protect the patient whenever it can be done without compromising the diagnostic quality of the image. If shielding would interfere with the image or obscure anatomy, it may be omitted for that view. The other points—shielding reduces exposure, and it must fit properly to be effective—are correct.
