The use of high-speed film, rare-earth intensifying screens, digital radiography, rectangular collimation, long tubes, and other radiographic equipment and techniques have made radiographic use in the dental office easier and safer for dental professionals and patients.  Both conventional and digital radiology continue to play an important role in the practice of dentistry, and the field of dental radiology evolves with advances in technology and techniques that cut patient radiation exposure dramatically.


This basic-level course is designed as a review of radiography for dental professionals. The course addresses different types of radiographic equipment, compares intraoral and extraoral film, discusses film positioning devices and paralleling techniques, and describes extraoral film projections. Types of digital receptors and the use of intensifying screens are also presented.


The course discusses common radiographic techniques and challenges, including common radiographic mistakes, working with patients with a severe gag reflex, dimple-down techniques, paralleling techniques, focal lengths, and collimation. Darkroom and film processing techniques, including the proper use of safelights and film baths, are explained along with common radiographic and processing errors. The course emphasizes the importance of standardized, consistent film mounting in the darkroom for accurate interpretation of patient x-rays.

The content of this course is helpful in training new staff members as well as refreshing the knowledge of seasoned personnel; dental professionals can also review the material to enhance diagnostic accuracy and reduce patient exposure to radiation.
