Why We No Longer Use Lead Aprons for Dental Xrays

You may notice that we no longer place a lead apron or thyroid collar on patients during dental x-rays. This change follows updated national guidelines based on strong scientific evidence. After reviewing published studies on radiography, an expert panel from the American Dental Association (ADA) determined lead aprons and thyroid collars are not necessary to shield patients from radiation exposure. These recommendations apply to all patients, regardless of age or health status (like pregnancy). Here’s what you should know:

• Modern X-rays are safer: Digital x-rays use much smaller radiation doses than older x-rays and restrict the beam size, thus reducing radiation exposure and the associated risks. Research shows these levels are so low that shielding is no longer necessary.
• Decades of studies show no harm: Extensive research has found no measurable risk from the small amount of radiation used in modern dental imaging.
• Lead aprons can interfere with the X-ray: Lead aprons may cause more dangerous rebound radiation. In addition, aprons and collars can accidentally block the area the dentist needs to see, causing images to be unclear or the need for the x-rays to be repeated.
• National guidelines have changed: In addition to the ADA, organizations such as the American College of Radiology (2021), They American Association of Physicists in Medicine (2019) and the American Academy of Oral and Maxillofacial Radiology (2023) now recommend not using lead aprons for routine dental X-rays, because they offer no added benefit with today’s technology.
