DASLE Radiology review
2025 with complete verified
solutions
If pt is a gagger, which film should be taken first? - answer Anterior Films
Which exposure technique will reduce radiation to the eye and thyroid
gland? - answer Paralleling Technique
What types of light is allowed in the Dark Room? - answer Safelighting:
7-5 watts, red-orange spectrum
Overhead light: for cleaning and visibility
What causes cone cutting of the film image? - answer Incorrect PID
alignment.
Exposure error: the entire film was not exposed.
What causes white, chalky spots on film? - answer Water spots on film.
Fixer spots are white or lighter areas.
If the film is curved or over-contoured, how will the radiographic image
appear? - answer Distorted or Elongated.
Define overlapping - answer One image is superimposed over another
image-caused by incorrect horizontal angulation when the central ray is
not directed through the interproximal spaces of the teeth.
Which technique causes the zygomatic to be superimposed on the roots of
the MX molar? - answer Bisecting Technique- the primary x-ray beam is
aligned with the bisector, an imaginary line between the film and long axis
of tooth.
, If you use too much VA how will the radiograph appear? - answer
Forshortened
Which type of radiation is the most hazardous to the operator? - answer
Scatter Radiation
3 types of radiation: 1. Primary - answer radiation emanates from focal
area as a result of high-speed electrons hitting the target of the anode in
the x-ray tubehead.
3 types of radiation: 2: Secondary - answer result of interaction of
primary radiation with matter.
created when primary beam interacts with matter.
3 types of radiation: 3. Scatter - answer results from an x-ray beam that
has been deflected from it's path by interaction with matter
How should films be stored? - answer Dry, cool, dark place
Explain why the body cannot be exposed to a large amount of radiation in
a short period of time. - answer cells do not have time to repair
themselves and results in damage that cannot be repaired.
If the exposure time, KVP, and Ma have been set correctly, the most
important controlling factor for image definition is the ______ and ______ of
the pt. - answer Positioning and cooperation.
The exposure time of a dental radiograph should be _______ for a child than
that of an adult. - answer Less
Quantity of dental radiographs is controlled by the ____ of the radiographic
machine. - answer mA's
