Objective While three-dimensional radiographs are commonly used in dentistry andprior work has focused on the effective dose of Cone Beam Computed Tomography CBCT, little is known about the dose or frequency of use of the preliminary scans usedto position patients prior to a full scan. Methods Positioning scan effective dose was measured with metaloxidesemiconductor field-effect transistor MOSFET dosimetersfor five CBCT devices in a postgraduate dental clinic. Additionally, log files from 2013-2015 were examined to obtain information on the clinical use of preview scans for the two highest dose devices.
