Flashcards in DENT 1050 Chapter 28 Deck (36):
1

TRUE or FALSE
ANATOMIC ORDER refers to how teeth are arranged in the dental arches.

True.

2

TRUE or FALSE
A clear film mount is preferred (instead of an opaque film mount) for better interpretation of radiographs.

False.
An opaque film mount is preferred because it masks the light around each radiograph. Subtle changes in density and contrast are easier to detect when the extraneous light is eliminated.

3

TRUE or FALSE
Only the dentist is qualified to mount dental radiographs.

False.
Any trained dental professional with knowledge of the normal anatomic landmarks of the maxilla, the mandible, and related structures is qualified to mount dental radiographs.

4

TRUE or FALSE
Films may be mounted at any time after processing.

False.
The dental radiographer should always mount films immediately after processing.

5

TRUE or FALSE
Mounted films are quicker and easier to view and interpret.

True.
compared to individual films

6

TRUE or FALSE
Mounted films decrease the chances of error in distinguishing the patient's right and left sides.

True.

7

TRUE or FALSE
Film mounts decrease the handling of individual films and prevent damage to the emulsion.

True.

8

TRUE or FALSE
In the labial film mounting method, all the embossed identification dots are placed in the film mount with the raised (convex) side facing the viewer.

True.

9

TRUE or FALSE
The lingual mounting method is widely used and is recommended by the American Dental Association.

False.
Labial mounting is the preferred method of mounting dental radiographs and is recommended by the American Dental Association.

10

TRUE or FALSE
Bite-wing radiographs must be mounted with the curve of Spee directed downward toward the distal.

False.
Curve of Spee directed upward toward the distal.

11

TRUE or FALSE
FILM VIEWING refers to the placing of films in a supporting structure.

False.
Film viewing means "examining or inspecting."
Film mounting refers to the placing of films in a supporting structure.

12

TRUE or FALSE
Although all members of the dental team may view films, it is the responsibility of the dentist to establish a final, or definitive, interpretation and diagnosis.

True.

13

TRUE or FALSE
Mounted radiographs may be viewed by holding the film mount up to the room light.

False.
Avoid holding mounted films "up to the room light" to view.

14

TRUE or FALSE
If the viewbox screen is not completely covered by the mounted radiographs, the harsh light around the mounted films must be masked to reduce glare and for better interpretation.

True.

15

TRUE or FALSE
When interpreting dental radiographs, an area free of distractions and with dimmed room lighting provides optimal viewing conditions.

True.

16

TRUE or FALSE
Optimal viewing conditions are typically present in the dental setting.

False.
Such viewing conditions are typically present only in a medical facility, so most films are examined on the viewbox at chairside in the dental setting.

17

TRUE or FALSE
Mounted radiographs must be viewed in an established sequence to prevent errors in interpretations.

True.

18

TRUE or FALSE
The dental radiographer must examine mounted radiographs many times to check for the presence of disease and abnormalities.

True.

19

TRUE or FALSE
After film viewing, all positive findings must be noted in the patient record.

True.

20

TRUE or FALSE
A viewbox is not necessary to examine dental radiographs.

False.

21

List five reasons for using a film mount.

1. quicker and easier to view and interpret
2. more easily stored in patient record
3. decrease the chances of error in determining the patient's right and left sides
4. decrease the handling of films
5.

22

List and describe the two methods of film mounting.

1. Labial - convex dot toward dental radiographer*
2. Lingual - convex dot away from dental radiographer

23

Describe the step-by-step procedure for film mounting.

Right side of patient goes into left side. Start at Maxillary right into the upper left. Clockwise (in mouth and mount) to right of mount, down and back to lower left of mount. Up in center to bite-wing on left then clockwise to right.

24

List and describe the necessary pieces of equipment for film viewing.

Light source and magnification.

25

Describe the step-by-step procedure for film viewing.

Sequential order. Separate examinations for each of the following:
-Unerupted, missing and impacted teeth
-Dental caries and size and shape of pulp cavities
-Bony changes, level of alveolar bone, and calculus
-Roots and periapical areas
-All areas not previously examined
