Digital x-ray sensors are among the most important equipment innovations in modern dentistry. Capable of capturing the intraoral x-rays that are a part of many hygiene and treatment appointments, sensors offer better images than film while taking less time and reducing the radiation exposure for patients and clinicians alike. There are numerous features and specifications that set these sensors apart from each other, but at a glance, most of them are fairly similar. A typical digital sensor is a small, black rectangle with a flat surface and a cord trailing away from the back side. Some sensors are available in multiple sizes, but in general, it can be difficult to tell one from another. But there are numerous differences among the available sensor options, and a handful feature novel attributes. The new DEXIS FS Ergo sensor is slightly pliable to offer greater comfort and ease in positioning. The Suni IQ sensor features a crisp, white face which makes it easier to see in the mouth for proper positioning. The MyRay X-Pod is a wireless option with a handheld view screen to see images immediately on the device. The ACTEON X-Mind Unity with SOPIX Inside system integrates the sensor with the x-ray generator for seamless operation. Finally, the SOLO sensor from Jazz Imaging looks and works like most sensors, but it is sold as a service so hardware updates are a part of the program. See the chart below for how these stand-out sensors stack up side-by-side.
