The protective gowns used by dentists can actually do more harm than good, top experts say.
Anyone who has had an X-ray at the dentist is familiar with the heavy lead apron that is draped over them, meant to reduce the radiation exposure to other parts of the body.
But experts at Tufts University say they are no longer necessary because of the accuracy of modern X-ray machines.
The skirts can actually do more harm than good as they impede clear absorption from the jaw and require a retry thus doubling the total dose.
Wearing a lead apron during a dental x-ray can interfere with a clear view of the jaw, especially if it has a collar, requiring a second attempt – doubling the total dose
Dr. Aruna Ramesh, professor of dental radiology at Tufts University School of Dental Medicine (TUSDM) in Boston, Massachusetts, said: “There is ample evidence in the scientific literature that the apron and thyroid collar provide no additional benefit.”
The American Academy of Oral and Maxillofacial Radiology (AAOMR), which provides evidence-based recommendations to dentists and others, released new guidelines in August that say lead aprons and thyroid shields do not need to be routinely used for dental X-rays.

Almost five million more people are recommended to be screened for lung cancer.
Through “internal scattering,” patients receive only a “negligible” amount of radiation to areas away from the head. This happens through “internal scattering” – where a small amount of radiation penetrates the head and neck and is reflected to other parts of the body. says Dr. Ramesh said.
“The internal spread that exposes the organs under the jaw cannot be prevented with an apron,” he said.
However, you will probably still need to wear one for your next dental x-ray.
Most states have regulations that require protective equipment during the procedure. Until these rules are changed, which must be done on a state-by-state basis, dental teams will most likely continue to use aprons and shields.
Anthony Blatnica, assistant professor of radiology at Tufts University School of Medicine, said: “If it’s not in the primary beam, you’re just dealing with internal scattering. And so external shielding doesn’t make sense.”
If some of the layer gets into the X-ray field and obscures the anatomy, “it becomes problematic,” he said.
However, some patients appreciate the comfort that the lead apron provides, both physically (like a weighted blanket) and mentally.
Dr. Hugo Campos, associate professor and director of oral and maxillofacial radiology at TUSDM, said: “The lead apron plays a very important role in the psyche of our patients. “They feel as if you are protecting them.”
But current X-ray techniques and technology provide adequate protective measures, such as targeted X-rays.
Dr Campos said: “With the shield, the same dose is absorbed as without the shield – and it is extremely low.”
