Are lead aprons a thing of the past?
Appropriate radiographic prescription is the most effective way to eliminate unnecessary radiation.
Collimation for intraoral radiography also reduces patient dose by 60%.
In the past, shielding during x-rays was a long-standing practice and mandated in many states. However, recent studies have not found that x-rays have caused any mutations or diseases. Because of these findings, it has been recommended to discontinue shielding of the gonads, pelvic structures, and fetuses during all dental radiographic imaging.
Internal scatter radiation is from within the body, which a lead apron does not shield against. In the dental office, lead aprons do not decrease the radiation absorbed by reproductive organs.
Also, the risk of thyroid cancer is negligible, so the new recommendation is to discontinue using a thyroid collar during dental x-rays.
The American Academy of Oral and Maxillofacial Radiology published an article based on evidence-based recommendations.
As a provider, since we are exposed many times throughout the day, it is still essential that we follow guidelines to limit our exposure. These guidelines include staying at least 6 feet from the x-rays source, leaving the room, and standing behind a suitable barrier.
