Computed Dental Radiography (CDR) is a technology for capturing a computerized image or radiograph of your teeth and gums that requires 90% less radiation than conventional x-ray film. CDR images are captured by sensors placed in the mouth that relay data to an attached computer, where the images are stored for viewing. Unlike conventional dental x-rays, CDR images can also be enlarged up to 300 times normal size to aid in diagnosis. They can also be manipulated for contrast and the colors can be adjusted. Images are captured instantly and do not require film developing and mounting.
