Radiographic units designed for dental and/or oral cavity imaging. These units include an x-ray generator, an x-ray tube (usually with stationary anode), a collimator, an exposure timer, patient positioning features and a control panel. The configuration of these components depends on the type of radiography performed and the type of x-ray generator used. Most dental radiographic unit x-ray tubes have a voltage range from 50 to 100 kV, and a current range from 1 to 20 mA. Dental radiographic units are used for imaging dentition, individual tooth anatomy and dental problems, as well as for orthodontic planning and assessment.
