16
Q

which areas may not be adequately seen on the dental images of patients with bone loss because of the narrow dimension of the receptor.?

A

crestal bone

17
Q

term used to describe the alignment of the central ray of the x-ray beam in both horizontal and vertical planes.

A

angulation

18
Q

refers to the positioning of the central ray in a horizontal, or side-to-side, plane

A

horizontal angulation

19
Q

With correct horizontal angulation, the central ray is directed _______to the ______ of the _____ and through the contact areas of teeth.

A

perpendicular
arch
curvature

20
Q

what does incorrect angulation result in ?

A

overlapped “unopened” contacts

21
Q

refers to the positioning of the PID in a vertical, or up-and-down, plane

A

vertical angulation

22
Q

when a bitetab is used without a beam alignment device, what should the vertical angulation be ?

A

+10 degrees

23
Q

incorrect vertical angulation used in the exposure of a bitewing results in what?

A

distorted image - non diagnostic

24
Q

where should bitewing exposures be prescribed?

A

areas where teeth have interproximal contact with adjacent teeth

25
Q

a total of how many bite wing images are exposed?

A

4

26
Q

When posterior teeth are missing , how many bitewing exposures me be sufficient?

A

one bitewing exposure on each side

27
Q

the specific area where the receptor must be positioned before exposure,

A

receptor placement

28
Q

When are vertical bitewings used ?

A

for post treatment or follow up images for patients with bone loss due to
periodontal disease

can be used to examine the level of alveolar bone in addition to caries detection

29
Q

an area where teeth are no longer present.

A

edentulous space
