GRADED A+
which radiographic technique records the most accurate image of crowns, roots, and
supporting structures in a selected area? - ANSWER: Periapical
When the parallel technique is used, the central ray makes a right angle with which
structure(s)?
A. The film or image receptor only
B. The long axis of the tooth only
C. The film or receptor and the long axis of the tooth
D. The portion of the bite block that the patient closes down on - ANSWER: The film
or receptor and the long axis of the tooth
The primary diagnostic use of interproximal (bitewing) radiographs is to - ANSWER:
Detect caries between the teeth and evaluate crestal bone levels
The standard film size used for adult bitewings and posterior periapical images is no.
- ANSWER: 2
A no. 1 size film would most likely be used to image which of the following areas on
an adult patient? - ANSWER: Incisors and canines
The premolar bitewing or receptor should be placed to include which of the
following anatomic structures at the anterior edge of the image? - ANSWER: The
distal half of the mandibular canine
Which of the following anatomic structures must be captured in a maxillary pemolar
and periapical image? - ANSWER: The distal half or one third of the canine and the
premolars
One of the most common problems associated with correct positioning of
mandibular periapicals or bitewings is - ANSWER: Positioning the film or receptor too
close to the lingual surface of the teeth
When using x-ray film, film-bending in the apical area is a common problem to try to
avoid in each of the following views except one. Which one is the exception?
A. Maxillary molars
B. Maxillary premolars
C. Mandibular premolars
D. Bitewings - ANSWER: Bitewings
, Incorrect horizontal angulation causes - ANSWER: Overlapped images because the
lingual aspect of one tooth is superimposed on the facial aspect of the adjacent
tooth
The latent image on a radiograph is - ANSWER: An unseen image produced by silver
halide crystals that have been exposed to radiation and that contain various levels of
stored energy, making a pattern
During the chemical processing procedure, the fixer - ANSWER: Removes the
unexposed silver halide crystals, leaving a white (clear) area where those crystals
used to be
A stepwedge may be used to
A. Check the darkroom for light leaks
B. Determine film speed
C. Determine processing times when chemical temperatures vary
D. Check the quality of processing chemicals - ANSWER: Check the quality of
processing chemicals
The emulsion is softened, and exposed silver halide crystals precipitate from within
the gelatin onto the film base during - ANSWER: Developing cycle
After processing, you find a check film to be too light. The temperature was
appropriate for the developing time. No log shows how long the chemicals have
been used. Which of the following is an appropriate step to take? - ANSWER: Change
the chemicals
After doing a coin test, you see a slight but noticeable well-defined white circle on
the processed film. This indicates - ANSWER: A light leak or unsafe safelighting
The primary reason that automatic processors are much faster than manual
processing is that automatic processors - ANSWER: Have higher developing
temperatures
Given that exposure errors are not the problem, processed films that are too dark
may be the result of - ANSWER: Developing time that is too long or developer that is
too warm
The reducing agent in the developer responsible for building the black and gray
tones is - ANSWER: Metol or Hydroquinone
The fixing agent that clears the unexposed crystals is - ANSWER: Ammonium
thiosulfate
You retrieve films from a patient's chart and find them to be brownish, opaque, and
difficult to interpret. This could be caused by any of the following reasons except
one. Which one is the exception?
