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 x-ray machines, as well as powerful dental software programs to assist the dentist with image acquisition and diagnostic analysis of the acquired images.

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.

Your dentist or the dental tech inputs the command for the dental X-ray machine to send a X-ray through your teeth and into the sensor, effectively taking a photo of your tooth or teeth. The sensor captures the resulting image and sends it through the wire to the computer. Then your dentist will reposition the sensor and take additional digital X-rays until all of your teeth have been X-rayed.

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.

This file can then be used by medical staff members, and the file can be attached to a patient’s medical notes for future reference. It can be printed to paper or slide material so can be used the same as any standard X-ray, but without as much risk and usually at lower overall cost. The initial expenses with a digital system can be immense, but over time they usually pay for themselves. These sorts of imaging devices are most commonly seen in hospitals, specialist medical practices, and dental offices. Dental imaging requires a slightly different process but the technology and basic concept are the same.

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.
