TU-A-Salon BCD-1 Tuesday 7:30:00 AM - 9:30:00 AM Room: Salon BCD

Recent improvements in digital dental imaging have created new opportunities for medical physicists to contribute to its safety and quality. Cone Beam Computed Tomography (CBCT) has dramatically grown in to many dental specialty practices, and even into the offices of general dentists. In 2009, NCRP Report #160 estimated the order of magnitude of dental x-ray images to 100 million dental x-ray images are acquired annually in the USA.

As digital dental imaging technology has advanced, increasingly ''user friendly'' systems have created the opportunity for sub-optimally trained personnel to deliver more radiation than is needed for digital dental exams (think ''Dose Creep'', and more). Recent reports on dental imaging, including CBCT, from the American Dental Association, FDA and IAEA will be summarized.

This presentation will begin with common problems encountered in film based dental imaging, but will primarily be focused on the digital dental imaging environment. Methods for evaluating the performance of dental radiography, cephalometric, panoramic and CBCT will be presented. The medical physics requirements for the Intersocietal Accreditation Commission CT Accreditation Program for dental CBCT systems will be reviewed.

Learning Objectives:
1. Understand the impact of digital imaging on the dental radiation safety
2. Understand the methodology for performance evaluations of dental imaging systems
3. Understand the medical physics requirements for IAC CT accreditation of dental CBCT systems
