Investigations: Dentists Using More High-Radiation Devices

While doctors have mounted campaigns to limit radiation use on children and adolescents, dentists are going in the opposite direction, reports this New York Times investigation. Not only do most dentists still use outmoded X-ray equipment; they are also increasingly using devices called cone-beam CT scanners that emit hundreds of times more radiation than an airport scanner. They provide 3-D images of teeth and the skull and are widely used when kids get braces.

The device's makers often market the product with the help of dentists paid or sponsored by the companies, who the Times says have peddled misleading information.
