Benefits of Digital Radiography

What are the benefits of digital radiography?

  • The film is immediately processed and available to view, whereas film takes time to be developed, and thus the patient’s wait time is decreased

  • Less radiation needed to produce the same quality image as film (digital X-rays gives 70% less exposure to radiation than conventional X-rays), thus more x-rays can be taken if needed without added risk

  • You can enhance the digital image (such as alter brightness and contrast) with a series of processing techniques, increasing the accuracy and detection of smaller cavities

  • Digital archiving—the ability to store images on a computer, allowing viewing of images at multiple locations

  • Digital radiography produces larger photos to better source hard-to-see cavities, which means earlier detection and less tooth destruction

  • Digital radiography, though expensive to buy initially, is cheaper and more environmentally friendly in the long run

  • Grey-scale of digital X-rays offers 256 shades of grey versus 16-25 shades in conventional radiography.

Your Child’s First Visit to the Dentist

By Dr. Kopel
Children should have their first dental checkup within 6 months of their first tooth eruption or by their first birthday. At this age only a visual exam will be done but early dental problems may be detected and parental questions can be answered. Early checkups also provide the child with a safe first experience.

There are no hard rules on when x-rays should first be taken. If decay is detected in a visual exam then x-rays should be taken to see areas of the teeth that are not clinically visible. Otherwise, by the age of 5-6 when permanent teeth start erupting they should be taken.
