Which statement best describes the role of PPE and shielding in dental radiography?

• A. PPE is optional.
• B. Shielding is unnecessary with modern sensors.
• C. Use of PPE and shielding is essential for safety.
• D. PPE should be removed during imaging.

Answer: (C)

Protecting people from scattered x-rays is built on two practical safeguards: personal protective equipment and shielding. The PPE used in dental radiography—primarily the lead apron and thyroid collar—helps shield the patient and reduces scattered radiation reaching the operator. PPE also includes infection-control items like gloves, though those don’t provide radiation protection. Shielding refers to barriers, room design, and proper imaging practices that block or reduce exposure, such as standing behind a leaded wall or barrier and using appropriate positioning and collimation to limit where the beam goes. The emphasis here is staying true to safety principles even with modern equipment. Regardless of advances in sensors or detectors, some radiation is still produced and scatter can reach the operator. Maintaining PPE and shielding aligns with the ALARA principle—keeping exposure as low as reasonably achievable. That’s why the statement that PPE and shielding are essential for safety is the best choice. PPE is not optional, shielding is not unnecessary with newer sensors, and PPE should not be removed during imaging.
