The nation’s largest dental association is changing its recommendations regarding the use of lead aprons and thyroid collars during dental x-rays. The American Dental Association (ADA) will no longer advise the use of these protective measures due to advancements in x-ray technology. With more focused x-ray beams, there is reduced concern about radiation exposure to other body parts, and the aprons and collars can sometimes obstruct dentists from obtaining necessary images.
Dr. Purnima Kumar, chair of the ADA Council on Scientific Affairs, emphasizes that the key to minimizing radiation exposure is ensuring the necessity of the x-ray and performing it accurately the first time. Dental x-rays inherently use a small amount of radiation, comparable to the exposure during a cross-country flight.
The ADA’s recommendation serves as guidance, and the actual implementation depends on state dental boards, dentists, and patients. For instance, California currently mandates the use of lead aprons. Dr. Sanjay Mallya, a radiologist and UCLA professor, highlights the lack of conclusive scientific evidence supporting the need for lead aprons. Despite this, legal requirements may persist, and advocacy and education are essential to change perceptions among patients, dentists, and policymakers regarding the use of lead aprons during dental x-rays.
