                          Digital Radiography (CDR)
Dental X-rays can now be taken using sensors that transmit 
                          the image directly into a computer monitor. This larger 
                          image helps the patient understand the doctor's explanations 
                          more easily and enables the doctor to "zoom in" 
                          on a specific area of the tooth. An important advantage 
                          to this new technology is that it reduces the amount 
                          of radiation by 90%. Digital X-rays are also faster. 
                          The digital image only takes 20 seconds to appear in 
                          the monitor. In addition, this new technology is friendly 
                          to the environment since no chemicals are needed for 
                          developing the image.   What are Dental X-rays?What most people call X-rays are actually X-ray photographs 
                          (also known as radiographs). An image is made using 
                          X-rays, which are similar to sunlight, but of a shorter 
                          wavelength, and able to show us what's below the surface 
                          of a tooth. Even though we call them X-rays, we are 
                          actually referring to the image created by X-rays. Why are Dental X-rays Necessary?X-rays are the only way to identify problems that aren't 
                          externally visible. X-rays are very essential in doing 
                          a complete and thorough dental examination. They are 
                          especially important in diagnosing serious conditions 
                          early to allow for effective treatment before 
                          you experience discomfort. X-rays show bone anatomy 
                          and density, decay between 
                          the teeth or how extensive the decay is, whether an 
                          abscess is present, impacted 
                          teeth, or if children have permanent teeth.

                            | No cavity on first X-ray. |  Months later, cavities that 
                                start between the teeth can't be seen by visual 
                                examination, but they can be detected on an X-ray. |  This cavity was detected and filled before the patient 
                          felt any discomfort, and before the nerve became infected 
                          or the tooth became abscessed. 
                         There is another cavity shown in the X-ray on the right. 
                          Can you find it? It's difficult for the untrained eye 
                          to spot.  Click here to see where it is. (Hint: It's not the 
                    left edge of the top left tooth. That's just the edge of the 
                    frame around the X-ray). How Often Do I Need Dental X-rays?The number and type of X-rays you will need depends 
                          on several factors such as age, current dental health, 
                          and external signs that may trigger a cause for concern. 
                          We are sensitive, however, to your concerns about exposure 
                          to radiation, and we only perform those X-ray procedures 
                          that are necessary for your continued dental health. Still Have Questions or Concerns?If you have any questions or concerns about dental 
                          X-rays, feel free to discuss them with any of our staff. 
                          They are highly trained in the prudent and effective 
                          use of dental X-rays and share your concerns about exposure 
                          levels.                         |
