Question 1

The film mount should be labeled ____ the films are mounted. A(n) ____ can be used to label film mounts.&#10;A) Before; special marking pencil&#10;B) After; special marking pencil&#10;C) Before; ink pen&#10;D) After; standard graphite pencil

Accepted Answer

The film mount should be labeled before the films are mounted and a special marking pencil can be used to label film mounts. This ensures that there is no confusion or mix-up in the order and labeling of the films. Using an ink pen or standard graphite pencil may not be as clear or long-lasting as a special marking pencil.

Question 2

Suggestions for mounting radiographs include mounting bite-wing radiographs with the curve of Spee directed ____ toward the distal and remembering that most maxillary molars have ____ roots.&#10;A) Upward; two&#10;B) Upward; three&#10;C) Downward; two&#10;D) Downward; three

Accepted Answer

The curve of Spee should be directed upward toward the distal when mounting bite-wing radiographs, and most maxillary molars typically have three roots.

Question 3

The text recommends viewing radiographs ____ in a room with ____ lighting.&#10;A) as many times as necessary; bright&#10;B) as many times as necessary; dimmed&#10;C) A single time; bright&#10;D) A single time; dimmed

Accepted Answer

The text recommends viewing radiographs as many times as necessary, but in a room with dimmed lighting. Dimmed lighting helps to reduce glare and improve contrast, making the images easier to interpret. Bright lighting can cause glare and wash out some details in the radiograph.

Question 4

When viewing radiographs, it is easier to detect subtle changes in density and contrast if:&#10;A) The treatment room lights are left on.&#10;B) Extraneous light is eliminated.&#10;C) The viewbox light is turned off.&#10;D) Films are held up by the operator and viewed through ceiling lights.

Accepted Answer

Extraneous light can interfere with the radiograph viewing by obscuring subtle changes in density and contrast. Eliminating extraneous light by viewing radiographs in a dark room or using light-blocking shield can enhance the image quality and aid in the detection of minute details. Therefore, option B is the correct choice. The other options, such as leaving treatment room lights on, turning off viewbox light, or holding films up to ceiling lights are incorrect as they can hinder the diagnostic ability and may result in inaccurate diagnoses.

Question 5

The dental radiographer should always mount films ____ after processing.&#10;A) Immediately&#10;B) 24 hours&#10;C) 3 days&#10;D) 1 week

Accepted Answer

Mounting films immediately after processing ensures that they are still fresh and won't be lost or misplaced. It also allows for quick identification of any retakes that may be needed. Delaying mounting for 24 hours or longer can make it more difficult to determine which film belongs to which patient or appointment.

Question 6

With the lingual mounting method, films are viewed from the ____ aspect. The lingual method ____ recommended.&#10;A) Labial; is&#10;B) Labial; is not&#10;C) Lingual; is&#10;D) Lingual; is not

Accepted Answer

With the lingual mounting method, films are viewed from the lingual aspect, and it is not recommended to view them from the labial aspect. Therefore, the correct choice is D.

Question 7

It is desirable that radiographs be identified with each of the following pieces of information, but it is critical that they be labeled with the:&#10;A) Patient's name and date of exposure.&#10;B) Number of films.&#10;C) Dentist's name.&#10;D) Radiographer's name.

Accepted Answer

The patient's name and the date of exposure are critical pieces of information to include on radiographs in order to ensure proper identification and tracking of the images. While the other pieces of information may be desirable to include, they are not as essential as the patient's name and date of exposure.

Question 8

When all the windows of the film mount are not filled with radiographs, the text recommends placing ____ in the unused frames.&#10;A) Masking tape&#10;B) Nothing&#10;C) Black opaque paper&#10;D) An unexposed film

Accepted Answer

Placing black opaque paper in the unused frames helps to prevent light leaks and fogging of the sensitive image receptor. This ensures that the quality of the radiographs is not compromised.

Question 9

A film mount may be made of:&#10;1) Cardboard&#10;2) Lead foil&#10;3) Plastic&#10;4) Vinyl&#10;A)1, 2, 3, 4&#10;B)1, 2, 4&#10;C)1, 3, 4&#10;D)3, 4

Accepted Answer

Cardboard, plastic, and vinyl are all commonly used materials for film mounts. Lead foil, however, is not a common material for film mounts and can be potentially harmful due to its toxicity. Therefore, options B and A should be eliminated, leaving option C as the best choice.

Question 10

Radiographs are intended to be placed in a film holder in:&#10;A) The order in which they were exposed.&#10;B) The order in which they were processed.&#10;C) Anatomic order.&#10;D) The order prescribed by the ADA nomenclature.

Accepted Answer

Radiographs should be placed in anatomic order (such as maxillary right, maxillary left, mandibular left, mandibular right) to make it easy to follow a patient's full oral health history.

Question 14

An opaque film mount is preferred because it:&#10;A) Increases the contrast of the radiograph.&#10;B) Increases the density of the radiograph.&#10;C) Decreases the density of the radiograph.&#10;D) Masks the light around each radiograph.
