Briefly state the importance of dental images

Decreases patient exposure to radiation, easy storage, instant review of radiograph, improves diagnostic potential (disease detection), less environmentally harmful waste

Dental radiographer

any person who positions and exposes dental receptors or films

Dental images are used to confirm or classify _________________.

Suspected disease.

Dental images are used to document the condition of a patient _________________.

at a specific point in time.

Who discovered x-rays and what year was that?

Wilhelm Roentgen, 1895

X-ray

a beam of energy that has the power to penetrate substances and record image shadows on receptors

Radiation

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

x-radiation

a high-energy radiation produced by the collision of a beam of electrons with a metal target in an x-ray tube

Radiograph

a picture (visible photographic record) on film produced by the passage of x-rays through an object or body

Image

a picture or likeness of an object

image receptor

a recording medium; examples include x-ray film, phosphor plate, digital sensor
