When DEXshield by DEXIS is used in conjunction with the DEXIS Platinum Sensor, this exciting new device not only reduces radiation to the patient, it also aids in proper positioning for image capture. During dental radiographic procedures, DEXshield’s tungsten core is able to block unnecessary X-rays. The resulting dose reduction does not affect image quality since the needed amount of radiation passes through the ring for optimal imaging results.
DEXshield takes the place of a standard ring. It was created to be easier to use than rectangular collimation, both of which were designed to reduce unnecessary dose to the patient. To overcome some of the limitations of rectangular collimation, DEXshield, when properly used with the DEXIS Platinum sensor, allows the operator to easily establish correct positioning and alignment.
Appropriate positioning minimizes cone cuts which subsequently may reduce retakes that, in turn, potentially reduces even more unnecessary exposure. DEXIS recognizes that dental professionals want to control dose in an efficient manner while maintaining high image quality and has made dose control a priority in its device design goals. One result of this commitment was confirmed by developing DEXshield which when combined with the DEXIS Platinum Sensor in recent laboratory testing, was determined to offer optimal results in imaging at a lower dose.
