Oral and maxillofacial radiology Total radiation doses from 3D dental<unk>  exams are 96% lower than conventional CT exams, but deliver more radiation than standard dental 2D x-ray (OPG). The time of exposure in<unk>  is also comparatively less when compared to conventional CT.<unk>  use is only lightly regulated in the US. The recommended standard of care is to use the smallest possible field of view (FOV), the smallest voxel size, the lowest mA setting and the shortest exposure time in conjunction with a pulsed exposure mode of acquisition. International organisations such as the World Health Organization and ICRP, as well as many local bodies and legislation, encourage the idea of justification for all medical exposures, where risks and benefits must be weighed up before a procedure goes ahead.
