Question 5

________ is the production of radiographs of the teeth and adjacent structures by the exposure of film to x-rays.&#10;A) X-ray&#10;B) Radiation&#10;C) Fluorescence&#10;D) Dental radiography

Accepted Answer

Dental radiography is the production of radiographs of the teeth and adjacent structures by the exposure of film to x-rays.

Question 6

What is the art and science of making radiographs by the exposure of film to x-rays?&#10;A) Radiography&#10;B) X-ray&#10;C) Dental radiographer&#10;D) Radiology

Accepted Answer

Radiography is the art and science of making radiographs by the exposure of film to x-rays.

Question 7

A picture on a film produced by the passage of x-rays through an object or body is termed:&#10;A) radiology.&#10;B) an x-ray.&#10;C) a radiograph.&#10;D) fluorescence.

Accepted Answer

A radiograph is an image or picture produced on a receptor (radiation-sensitive film, phosphor plate, or digital sensor) by exposure to ionizing radiation; a two-dimensional representation of a three-dimensional object. Specifically, a dental radiograph is a photographic image produced on film by
the passage of x-rays through teeth and related structures.
