X-rays and Dental Imaging

X-rays are a high-energy radiation produced by the collision of a beam of electrons with a metal target in an x-ray tube.
Dental images are used in patient care to diagnose and treat dental problems, monitor treatment progress, and detect diseases.

Components of an X-ray Machine

The main components of an extraoral x-ray machine do not include a developing tank.
A bite-block is used to position the patient's jaw during dental imaging.
A positioning device (PID) is used to help position the x-ray receptor in relation to the tooth.
A collimating device is used to restrict the x-ray beam to the size of the receptor, reducing radiation exposure.

History of Dental Radiography

Wilhelm Conrad Roentgen discovered x-rays in 1895.
Roentgen named his discovery "X-rays" because he did not know what they were.
The Eastman Kodak Company manufactured the first prewrapped intraoral films in 1913.
The first machine-made periapical film packets became available in 1913.
Dr. Otto Walkhoff made the first dental radiograph in 1896.
In 1947, F.Gordon Fitzgerald revived the technique of panoramic radiography.
C.Edmund Kells contributed to dentistry by being the first to use dental radiographs in practice.

X-ray Machine Control Panel

The control panel in a typical intraoral dental x-ray machine consists of a timer, a kVp and mA selector, and an exposure button.
