Digital radiography , or digital X-rays, have been around for seven years and allows a dentist to see inside the tooth. The dentist, who takes an X-ray that appears on a computer screen next to the patient's chair, can then enlarge or colorize the tooth to enhance problem areas. The new X-rays, used by an estimated 5 percent of dentists, are safer than the old method because they emit up to 90 percent less radiation. Six images of teeth can be taken for the same amount of radiation exposure it takes to process one piece of conventional film. While reduced radiation was his primary reason for using digital radiography, Plack said he was pleasantly surprised with the environmental and patient education benefits.
Employees spend less time developing film for the X-rays and are exposed to fewer strong chemicals.
In addition, dentists are required by environmental regulations to have these toxic chemicals hauled away by special removal services. Digital X-rays save on removal costs. But the biggest plus of the new tools is patient education, Plack said. Send it Email this to a friend. Use this version.
