What about the radiation dose in OPG?

Although the radiation dose associated with OPG and cephalometry is extremely low it is important that the procedure is performed using modern dose efficient equipment. In 2006 Barwon Health installed new digital OPG and Cephalometry systems that utilise direct radiography (DR) capture of the x-rays. This results in a potential dose reduction of 50% compared with conventional x-rays using either film or computed radiography (CR) phosphor plate technology. There are also specific paediatric dose reduction protocols.
