CHAPTER 19: BITEWING TECHNIQUE

Question 1

is a method used to examine the interproximal surfaces of teeth

Answer 1

Bitewing technique

Question 2

Between two adjacent surfaces.

Answer 2

interproximal

Question 3

Type of receptor used in interproximal examination. The bite-wing receptor has a “wing,” or tab, and the patient “bites” on the wing to stabilize the receptor.

Answer 3

bite wing receptor

Question 4

Bone that supports and encases the roots of teeth

Answer 4

alveolar bone

Question 5

Coronal portion of alveolar bone found between teeth; also known as the alveolar crest

Answer 5

crestal bone

Question 6

area of a tooth that touches an adjacent tooth; the area where adjacent tooth surfaces contact each other

Answer 6

contact areas

Question 7

thin radiolucent lines between adjacent tooth surfaces

Answer 7

open contacts

Question 8

the area where the contact area of one tooth is superimposed over the contact area of an adjacent tooth

Answer 8

overlapped contacts

Question 9

The receptor is placed in the mouth ______ to the crowns of both maxillary and mandibular teeth.

Answer 9

parallel

Question 10

When using a bite-wing tab, the central ray of the x-ray beam is directed through the contacts of teeth, using a vertical angulation of ___ degrees.

Answer 10

+10

Question 11

In the bite-wing technique, either a ______ device or a ______ tab is used to stabilize the receptor.

Answer 11

beam alignment device

bite wing tab

Question 12

device used to position an intraoral receptor in the mouth and maintain the receptor in position during the imaging procedure

Answer 12

beam alignment device

Question 13

To reduce the amount of radiation exposure to the patient, the use of this collimator for all intraoral exposures is recommended.

Answer 13

rectangular collimator

Question 14

an alternative to a beam alignment device used to stabilize the receptor during exposure

Answer 14

bite wing tab

Question 15

what size receptor is recommended in for bite wing exposures

Answer 15

size 2

Question 16

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

Answer 16

crestal bone

Question 17

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

Answer 17

angulation

Question 18

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

Answer 18

horizontal angulation

Question 19

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

Answer 19

perpendicular
arch
curvature

Question 20

what does incorrect angulation result in ?

Answer 20

overlapped “unopened” contacts

Question 21

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

Answer 21

vertical angulation

Question 22

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

Answer 22

+10 degrees

Question 23

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

Answer 23

distorted image - non diagnostic

Question 24

where should bitewing exposures be prescribed?

Answer 24

areas where teeth have interproximal contact with adjacent teeth

Question 25

a total of how many bite wing images are exposed?

Answer 25

4

Question 26

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

Answer 26

one bitewing exposure on each side

Question 27

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

Answer 27

receptor placement

Question 28

When are vertical bitewings used ?

Answer 28

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

Question 29

an area where teeth are no longer present.

Answer 29

edentulous space
