Digital dentistry refers to the use of computers and computer-controlled dental equipment in the provision of dental care. It encompasses things such as computer-aided diagnostic imaging, computer-aided design and fabrication of dental restorations such as crowns for individual patients, and dental lasers.

Digital radiography is a type of X-ray imaging in which the images are transposed digitally onto computers or other devices rather than being developed onto film. Instead of using electromagnetic radiation and chemical processing to record an X-ray onto film, digital versions use digital sensors to record images onto an image capture device, which then creates a digital image file.

When contemplating the change to digital dental in your practice, the choices can be confusing for the dentist. Dental radiography has evolved from film and chemical developers into a highly technical process that involves various types of digital dental x-ray machines, as well as powerful dental software programs to assist the dentist with image acquisition and diagnostic analysis of the acquired images. When making the decision to purchase x-ray equipment, the doctor needs to research the available options thoroughly, in order to make an informed choice for the “right” machine for his or her practice.

Like old fashioned dental X-rays, digital dental X-rays are used by your dentist to take images of your mouth, including tooth structure and your jaw bones. In order to take the digital images, your dentist – or a dental technician – will place a small sensor in your mouth, carefully positioned. This small sensor is connected to the processing computer by a very thin wire.

Most of the earliest X-rays depended on photographic films to capture the images and make them readable. Digital detectors skip this step; rather than using light beamed through objects onto film, it allows for digital scanning and image interpretation. In terms of radiation the two are about the same initially, though digital versions typically have a shorter exposure time and as such tend to be more efficient.
