We did find this article on the ADA website that reviews the updated recommendations. The article states:
“We are encouraging dentists to look at the issue of selecting radiographic examinations for their patients on an individual basis, not as a one-size-fits-all,” said Dr. Sharon Brooks, professor emeritus at the University of Michigan, who worked as a consultant with the ADA Council on Scientific Affairs to develop the new set of recommendations. “The guidelines are to help them make the decisions on the appropriate use.”
• Removing a stronger recommendation for thyroid collar use for children, women of childbearing age and pregnant women. The strength of the recommendation is now the same for all patients.
• A new section that was not in the 2004 document, which expands upon the 2006 CSA report, “The Use of Dental Radiographs: Update and Recommendations.”
• New topics that were not covered in the 2006 CSA report such as receptor selection, handheld X-ray units, technique charts and radiation risk communication.
• Changing the recommendation for shielding to be consistent with the National Council on Radiation Protection & Measurements
