Chapter 20 Flashcards
Which statement regarding digital imaging orientation is true?
D) Indirect digital imaging systems come with guides to orient plates into the scanner.
What is the next suggested step after orienting the embossed dots when mounting dental radiographs?
C) Separate bitewing radiographs from periapical radiographs.
Should all radiographs, whether intraoral or extraoral, be mounted?
FALSE
Film mounting refers only to intraoral films.
Are templates the digital equivalent of film mounts?
TRUE
Are clear plastic mounts preferred over black plastic or gray cardboard mounts?
FALSE
Black plastic or gray cardboard mounts are preferred as they block out extraneous light.
Should mandibular premolar and molar radiographs be oriented for a slight ‘smile’ appearance?
TRUE
Is the same knowledge needed for mounting film-based radiographs as for orienting digital images?
TRUE
Are some viewboxes equipped with a magnifying glass?
TRUE
Is correct mounting and orientation essential before interpreting dental radiographic images?
TRUE
Does the identification dot on intraoral radiographs distinguish the patient’s left and right sides?
TRUE
Is the lingual method of film mounting preferred?
FALSE
The labial method is preferred.
Do mandibular molars generally have two divergent roots?
TRUE
Can a practice contact a manufacturer for a custom-designed film mount?
TRUE
Is the embossed identification dot oriented correctly if the film packet is positioned properly?
TRUE
Can a radiograph only be viewed correctly from the side with the embossed dot convex?
FALSE
A radiograph may be viewed from either side.
Do clues assist in the orientation process of radiographs?
TRUE
Are the roots and crowns of the mandibular anterior teeth larger than those of the mandibular teeth?
FALSE
Maxillary anterior teeth are larger.
Are the genial tubercles found on maxillary anterior radiographs?
FALSE
They are usually recorded on anterior radiographs of the mandible.
Can anatomical landmarks like the oblique ridge be found on mandibular posterior radiographs?
TRUE
Should the computer monitor for viewing digital radiographs be in bright light?
FALSE
Overhead lighting can cause glare.
Is a systematic method for reading images beneficial for interpreting radiographs?
TRUE
Does the lingual method of mounting radiographs position the embossed dot convex?
FALSE
It positions the embossed dot concave.
What is the placement of radiographs in a film holder called?
Film mounting.
What distinguishes the patient’s right and left sides on an intraoral film?
The identification dot.
What helps develop the skill of interpreting radiographs?
A solid working knowledge of normal radiographic anatomy.
What type of film mount is preferable?
Black plastic or gray cardboard.
Which is the preferred method of mounting films?
The labial method.
Which method of film mounting is no longer recommended?
The lingual method.
How many roots do maxillary molars generally have?
Three.
What is radiographic interpretation?
Reading the radiograph and explaining findings in lay terms.
Who is responsible for interpreting a patient’s radiographs?
All members of the oral health care team.
What equipment is necessary for optimum film viewing?
A viewbox and magnifying glass.
