“…However, image quality might be lower than wall-mounted devices. 18 Image quality depends on the interaction of X-ray device, exposure time, exposure geometry and image receptor. In the study of Pittayapat et al, 19 it was concluded that handheld portable X-ray devices produce satisfactory image quality for use in forensic odontology.…”

Handheld portable X-ray devices are increasingly used for intraoral radiography. This development introduces new challenges to staff and patient safety, for which new or revised risk assessments must be made and acted upon prior to use. Major issues might be: difficulties in using rectangular collimation with beam aiming devices, more complex matching of exposure settings to the X-ray receptor used (e.g. longer exposure times), movements owing to the units' weight, protection of the operator and third persons, and the use in uncontrolled environments. These problems may result in violation of the "as low as reasonably achievable'', that is, ALARA principle by an increase in (re)exposures compared with the other available intraoral X-ray devices. Hence, the use of handheld portable X-ray devices should be considered only after careful and documented evaluation (which might be performed based on medical physics support), when there is evidence that handheld operation has benefits over traditional modalities and when no new risks to the operators and/or third parties are caused. It is expected that the use of handheld portable X-ray devices will be very exceptional, and for justified situations only. Special attention should be drawn to beamaiming devices, rectangular collimation, the section of the X-ray receptor, focus-skin distance, and backscatter shielding, and that the unit delivers reproducible dose over the full set of environmental conditions (e.g. battery status and temperature).

“…In a previous study [9], two portable X-ray units: AnyRay 1 (VATECH Co., Ltd., Gyeonggi-do, Republic of Korea) and NOMAD 1 (Aribex, Utah, USA) were evaluated and compared with a standard wall mounted radiographic unit: MinRay 1 (Soredex, Tuusula, Finland), on their performances with Vistascan 1 phosphor image plates (Dü rr Dental, Bietigheim-Bissingen, Germany) and SIGMA 1 M CMOS Active Pixel technology sensor (Instrumentarium Dental, Tuusula, Finland) CMOS image receptors. The ideal parameter set up for obtaining excellent image quality disregarding the object-toimage-receptor-distance (OID) was the phosphor plate system combined with the MinRay 1 unit and if a portable device is needed, the NOMAD 1 unit is recommended.…”

“…These provide a number of advantages for the forensic odontologist, including mobility 25 and ease of use. 26 They are battery-operated and therefore cordless, and free the forensic odontologist from the need to have access to electrical power at a scene where radiographs are required 26 (although access to power for battery recharging is needed if the operation requires more than the number of pre-charged batteries available). When used with digital sensors, these devices can increase the speed and efficiency of the imaging phase of the postmortem examination.…”

“…When used with digital sensors, these devices can increase the speed and efficiency of the imaging phase of the postmortem examination. It has been shown that their image quality is excellent when used with appropriate image sensors or film, 25,26 and that they are safe when used as recommended, posing no significant health risk to operating staff. 27 Nearly all forensic odontologists working in Australia now have routine access to a hand-held radiation source.…”

Forensic odontology is the application of dental expertise to legal issues. Commonly, it involves the comparison of dental records of a missing person with a deceased individual for the purposes of forensic personal identification, either in a single case, or as part of the response to an event involving multiple simultaneous fatalities (Disaster Victim Identification, or DVI). It may also involve studies to determine the age of an individual, which may be required as part of a forensic identification process, or for another legal purpose such as the determination of legal responsibility, or in connection with immigration. This report examines the types of radiological information currently used in such forensic studies, and discusses how this information may be accessed or recorded, as well as the techniques that are commonly applied to the radiological data to reach a satisfactory outcome for application in forensic casework.Keywords: Dental radiology, forensic, forensic odontology, forensic radiology, radiology.
