A photographic image produced on a receptor by the passage of x-rays through teeth and related structures.

Radiograph

A beam of energy that has the power to penetrate substances and record image shadows on photographic film.

X-ray

A form of energy carried by waves or a stream of particles.

Radiation

Any person who positions, exposes, and processes x-ray image receptors.

Radiographer, dental

The production of radiographs by the exposure of a receptor to x-rays.

Radiography

Discuss the importance of dental images.

Dental images are important because they provide information that cannot be obtained clinically and help detect diseases, lesions, and conditions of the teeth and jaws.

Summarize the discovery of x-radiation.

Wilhelm Conrad Roentgen discovered x-rays in 1895 while experimenting with cathode rays. He noticed that the rays could penetrate certain materials and produce images of internal structures.
