In a significant departure from conventional practices, the American Dental Association (ADA) has announced that it will no longer recommend the use of lead aprons and thyroid collars during dental X-rays. The decision comes as a response to advancements in X-ray technology, with more focused beams reducing concerns about radiation exposure to other parts of the body.
One of the main reasons behind this change is the improved precision of X-ray beams, rendering lead aprons and collars less necessary. Additionally, it has been noted that these protective gear items can at times obstruct dentists from obtaining clear and accurate X-ray images, prompting a reevaluation of their use.
Dental professionals are now advised to prioritize ensuring the necessity of X-rays and conducting them correctly to minimize radiation exposure. Despite concerns about radiation, dental X-rays involve a relatively small amount of radiation, akin to the exposure during a cross-country flight.
Importantly, the ADA’s recommendation is not a binding directive. The actual implementation of this change depends on state dental boards, individual dentists, and patient preferences. For example, California currently mandates the use of lead aprons by dentists under state rules.
Experts argue that there is no definitive scientific evidence supporting the necessity of lead aprons and thyroid collars during dental X-rays. While there is a lack of concrete scientific backing, regulations often require their use. Sanjay Mallya, a radiologist and professor at the University of California, Los Angeles, emphasized that there is “no hard science” supporting the need for these protective measures.
The ADA’s decision was influenced by a recommendation from the American Academy of Oral and Maxillofacial Radiology, which urged against the use of lead aprons and thyroid collars in the fall. This recommendation prompted the ADA to reevaluate the use of these protective measures.
Support for the recent guidance extends beyond dental associations, as medical physicists with the U.S. Food and Drug Administration have also endorsed the shift in guidelines. Supporters emphasize that reducing radiation exposure is not solely dependent on technology; it also involves ensuring the necessity of X-rays and opting for digital X-rays. Digital X-rays typically entail lower radiation levels compared to conventional film-based X-rays.
However, concerns have been raised about potential complacency regarding radiation exposure. Experts emphasize the importance of maintaining diligence in ensuring the necessity of X-rays and adopting technologies that reduce radiation, such as digital X-rays.
The road ahead involves advocacy and education to shift perspectives on the use of lead aprons among patients, dentists, and policymakers. While the ADA has taken a bold step in updating its recommendations, the ultimate impact will depend on widespread acceptance and implementation within the dental community.
