This report is urgently needed as there are no formal guidelines on the safe and effective use of these modalities in the United States. In addition, every dental practitioner acts as an independent radiologist. CBCT units are generally installed as plug-and-play devices and they are not perceived by most in dentistry as computed tomography (CT) units, but rather as exotic panoramic units. Many states consider these the same as simple, intraoral x-ray equipment for regulatory purposes. Hand-held dental x-ray units face a barrier with state regulators since long-term training emphasized to never hold the x-ray tube. (Hand-held units are specifically designed with sufficient shielding to eliminate significant radiation exposure to the operator—although this is not true of all units available for sale in the United States).
In the second quarter of 2013, the NCRP Board approved a proposal to establish SC 4-5 to write a revision of NCRP Report No. 145, Radiation Protection in Dentistry. The revision will address imaging modalities that have evolved over the past 10 y and update existing material as needed. New imaging modalities include, but are not limited to, cone-beam computed tomography (CBCT), digital radiography, and hand-held dental x-ray units. Other topics include the use of high-speed film (80 % of U.S. dental facilities continue to use film which requires twice the radiation dose to the patient compared to high-speed dental film) and new data from the Nationwide Evaluation of X-Ray Trends (NEXT) survey.
