A form of energy carried by waves or a stream of particles - Correct Answers Radiation is defined as
A picture on film produced by the passage of x-rays through an object or body - Correct Answers A
radiograph is defined as
Many dental diseases are typically discovered only through the use of dental images. - Correct Answers
Your patient asked you why dental images are important
Gordon Fitzgerald modified the paralleling technique with the introduction of the long-cone technique. -
Correct Answers Who modified the paralleling technique with the introduction of the long-cone
technique?
An image receptor is the recording medium (film, phosphor plate, or digital sensor) that is placed in the
patient's mouth to record the image produced - Correct Answers Which of the following would you
place in the patient's mouth in order to take dental x-rays?
. The K shell is the orbiting shell closest to the nucleus. - Correct Answers Which of the following
statements is true of orbits or shells in the atom?
determined by the distance between the orbiting electron and the *nucleus * - Correct Answers The
binding energy or binding force of an electron is
Insulating oil - Correct Answers Heat is a byproduct of x-ray production. Which component of the x-ray
tubehead dissipates the heat created by the production of x-rays?
Milliamperage - Correct Answers Which would you adjust if you wanted to create a larger electron
cloud?
quality - Correct Answers In dental radiography, the term ________ is used to describe the mean
energy or penetrating ability of the x-ray beam.
, Density is the overall darkness or blackness of a dental image. The first statement is true; however, the
second statement is false. - Correct Answers (1) Density is the overall darkness or blackness of a dental
image. (2) When the kilovoltage is increased while other exposure factors remain constant, the resultant
image exhibits a decreased density and appears lighter.
quantity of electrons produced at the cathode filament. - Correct Answers Milliamperage regulates the
_________ of electrons produced at the cathode filament.
four times as intense. - Correct Answers According to the inverse square law, if the length of the PID is
halved, the resultant beam is ___________ as intense.
Both statements are false; 1. An increase in kilovoltage, milliamperage, and/or time will increase the
intensity of the x-ray beam. 2. An increase in distance and/or filtration will decrease the intensity of the
x-ray beam. - Correct Answers (1) As kilovoltage, milliamperage, and time increase, x-ray beam intensity
decreases. (2) As distance and filtration increase, the intensity of the x-ray beam increases.
Total dose refers to the quantity of radiation received or the total amount of radiation energy absorbed.
- Correct Answers __ refers to the total amount of radiation that is received or absorbed
Both statements are true - Correct Answers (1) More radiation damage takes place with high dose rates
(2) because a rapid delivery of radiation does not allow time for cellular damage to be repaired.
Proper prescribing of radiographs is an example of a patient protection technique used before x-ray
exposure - Correct Answers Which of the following should you do prior to taking x-rays to protect your
patient from radiation exposure?
A thyroid collar - Correct Answers Intraoral protection
The lead apron is recommended for intraoral exposures (and extraoral films as well). - Correct Answers
The lead apron
Only the *exposure time* can be altered; the kilovoltage is preset by the manufacturer; the other
parameters are preset by the manufacturer; the PID length is determined by the manufacturer; the
