---|---|---|---|---|
What is Angulation
alignment of central ray of x-ray beam in horizontal and vertical planes
|
What is bitewing
type of image used for interproximal examination of both crowns and bone
|
What is perpendicular
intersecting at or forming a right angle
|
What is size 2
child occlusal images are taken with what size of receptor
|
What is central ray
– x-ray beam must be centered on the receptor to ensure that all the areas are exposed.
|
What is Calibration
scaling x-ray beam to proper size
|
What is occlusal
depicting large area of one arch
|
What is magnification
enlargement of an image
|
What is Bisecting the angle technique
the angle between the long axis of the tooth and the receptor divided in half
|
What is vertical angulation
the central ray of the x-ray of the beam must be directed perpendicular to the receptor and the long axis of the tooth
|
What is central ray
x-ray at center of beam; purest ray
|
What is periapical
radiographic view that shows the crown, root tip, and surrounding structures
|
What is overlapping
interproximal tooth surfaces are superimposed by incorrect horizontal angulation error, cannot view interproximal contacts
|
What is Paralleling technique
The central ray is aligned with the long axis of the tooth and the receptor at a right angle.
|
What is RECEPTOR POSITION
positioned parallel to the long axis of the tooth to be exposed.
|
What is bisecting angle
intraoral technique of exposing dental images; cutting angle in half
|
What is full mouth series
series consists of 18 to 20 images—generally, 14 periapical views and 4 to 6 bitewing views.
|
What is foreshortening
of images is caused by excessive (too much) vertical angulation, image is short and wide,
|
What is size 2
adult bitewings uses this size of receptor
|
What is RECEPTOR PLACEMENT
to cover intended region for exposure in the mouth
|
What is long axis of the tooth
imaginary line dividing the tooth longitudinally (vertically) into two equal halves
|
What is panoramic
extra-oral image commonly taken every 3-5 years
|
What is elongation
caused by insufficient (not enough) vertical angulation, image is long and stretched out
|
What is Right Angle technique
also known as Paralleling Technique
|
What is HORIZONTAL ANGULATION
the central ray of the x-ray beam must be directed through the contact area between the te
