What are the guidelines for using lead aprons and thyroid collars during dental radiography?

• A. Use lead aprons and thyroid collars as shielding for standard radiographs to reduce patient exposure, except where contraindicated by specific imaging goals; ensure proper fit and not interfering with imaging.
• B. Use only thyroid collars.
• C. Do not use shielding at all.
• D. They should always be used regardless of imaging goals.

Answer: (A)

Shielding with lead aprons and thyroid collars reduces radiation exposure to radiosensitive tissues during dental radiography and is appropriate for standard imaging, as long as it does not interfere with capturing the necessary anatomy. Use them with a proper fit: the apron should drape over the torso without restricting the radiographic field, and the thyroid collar should be snug around the neck so it shields the thyroid without touching the imaging area or causing artifacts. If a specific imaging goal requires exposure of areas near the shielding or the shield would obscure essential anatomy, adjustments are made and shielding may be omitted for that image. The goal is to minimize dose while preserving diagnostic quality.
