Lead Apron
A protective garment lined with lead or lead-equivalent material draped over a patient's torso and lap to shield radiosensitive organs during dental radiographic exposures.
Full Definition
The lead apron is a standard radiation protection accessory in dental radiography, designed to reduce the dose of scatter radiation received by the patient's thyroid, gonads, and other radiosensitive tissues not in the primary beam. It is typically constructed from a flexible lead or lead-composite material and is worn draped over the front of the patient's body during X-ray exposures. While its routine use for all dental radiographs is debated in contemporary evidence-based guidelines, it remains mandatory or recommended in many jurisdictions for paediatric patients and those who are pregnant. Editors working with radiation protection policies must ensure the lead apron is discussed separately from the thyroid collar, as they protect different anatomical regions. The term should always appear as two words without hyphenation.
Usage
Usage note: Editors should note that some current guidelines (e.g., FGDP UK) have revised recommendations on routine lead apron use; verify the governing guidance before editing clinical protocols.
