What training is required for dental assistants to operate radiography equipment?

• A. They must be licensed dentists.
• B. They must complete only general safety training.
• C. They must be authorized by a licensed dentist and trained under their direction.
• D. They require no supervision.

Answer: (C)

Operating radiography equipment requires specialized training and supervision because it involves exposure to ionizing radiation. A dental assistant may perform radiographic procedures only if they are authorized by a licensed dentist and trained under that dentist’s direction. This ensures the assistant has demonstrated competency in proper technique, patient positioning, exposure settings, shielding, and infection control, and that the supervising dentist remains legally responsible for the radiographs produced. General safety training alone does not provide the specific skills and regulatory authority needed for radiography, and working without supervision would violate regulations.
