Dr. W. asks:
In the Nov. 29 issue of the New England Journal of Medicine, David J. Brenner, Ph.D., D.Sc., and Eric J. Hall, D.Phil., D.Sc., of Columbia University, raised concerns over possible radiation effects of CT scans. Their study, which suggested that the current proportion of cancers attributable to CT-associated radiation could be as great as 1.5% to 2%, has since ignited significant debate in the medical community given the invaluable role that CT scans play in medical treatment. Many have claimed that Brenner and Hall's research is flawed.
Nevertheless, I'm wondering how my fellow dental practitioners are reacting to this latest news on CT Scans? Have your patients questioned you about this? Is this really a concern for our cases? How should we address the issue? Finally, I'm wondering how this warning about CT scans extends to Cone Beam Volumetric CT scans that we use in dentistry? Am I correct in assuming that the radiation level is lower with Cone Beam CT (CBCT)?
