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. 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 your practice.

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.

Digital dental radiography requires a slightly different process. Intraoral images are taken by asking the patient to bite down on an X-ray sensor placed inside the mouth. There is much less radiation involved in digital scans than in film-based electromagnetic radiation, so it is usually safe enough to take numerous X-rays and view all of the teeth from multiple angles. This is useful for checking for decay or tooth problems that can be easily missed during a clinical checkup.

One type of portable dental x-ray is small, light, cordless and hand-held and can travel almost anywhere considering its compact size. This type of portable x-ray machine is an option for almost every patient, however, it's especially useful for occasionally restless patients, such as young children, who require constant supervision and a quick x-ray. It can also be a better option to use in small spaces. The device works on battery so it's important to have extras on hand in addition to a fully charged battery upon arrival regardless of where the patients are.

The other type of portable dental x-ray is one that uses a power cord and is slightly larger and heavier than the hand-held device; it's also typically more durable. Each comes with a stand, which some dentists might find to be more comfortable and easier to use than a hand-held device. Some may also be able to operate as a hand-held device when using a stand isn't necessary. This type is a good option for dentists who prefer to have the features of each type.

The portable dental x-ray is not only useful to patients, but also to dentists who want to be able to help patients who don't have immediate access to a dental office. Without the device, there is no doubt that quite a few individuals would go without knowing the cause of their tooth pain. Though it doesn't mean they'll seek immediate dental care, it at least increases the chances depending on the results of the x-rays.
