100
Palatal and mandibular tori require this exposure technique.
What is bisecting the angle?
100
The technique that reduces distortion and radiation exposure to the patient.
What is paralleling?
100
Identify this projection and the angulation used to create it:
What is maxillary topographic and +65?
100
The imaginary bisector evenly divides the angle between these two points
What is the long axis of the tooth and the sensor?
100
He discovered x-rays.
Who is Wilhelm Conrad Roentgen?
200
An image that shows teeth not separated by thin black radiolucent lines has what exposure error?
What is overlap (horizontal angulation)?
200
The sensor must be protected from cross contamination by these two items:
What are the barrier and a finger cot?
200
Identify the opaque (B) and lucent (C) circular landmarks seen here: 
What is B= genial tubercles, C= lingual foramen?
200
The sensor in bisecting the angle is placed this distance from the occlusal.
What is 1/8"
200
This view/projection is used for checking the fit of metallic/opaque restorations:
What is the interproximal (BWX) technique?
300
When the image of the tooth appears shorter than it actually is, or the crowns are not visible ("cut off")?
What is foreshortening?
300
This law requires proper maintenance of x-ray equipment and for dental radiographers to be properly trained and certified.
What is the Consumer Patient Radiation Health and Safety Act?
300
Identify the radiolucent landmark seen between the apices of the mandibular premolars.
What is the mental foramen?
300
In the bisecting technique, the CR is perpendicular to this:
What is the imaginary bisector?
300
Identify the projection, angulation and PID position:
What is mandibular cross-sectional, 90 degrees and through the chin
400
Periodontal disease is diagnosed by this structure, best seen using the interproximal technique.
What is crestal bone height
400
A long (16 inch) PID reduces radiation exposure by limiting the spread of the x-ray, also called
What is divergence?
400
Identify the pear-shaped radiolucent landmark seen above the maxillary central incisors.
What is the incisive foramen?
400
This is the recommended vertical angulation for the interproximal (bitewing) technique:
What is +10 degrees?
400
A word that means to be free of pathogens, or a technique for setting up before dental radiography.
What is aseptic?
500
An image that is distorted and longer than the actual tooth, crowns may be "cut off"
What is overangulated?
500
This risk management process preserves patient autonomy and self-determination:
What is informed consent?
500
Identify this radiopaque landmark that lines each tooth socket indicated by the red arrow:
What is the lamina dura?
500
In the bisecting technique, mandibular vertical angulations typically are between 0 degrees and:
What is -20 degrees?
500
Identify this error and how to correct it:
What is forshortening caused by overangulation; decrease or reduce the vertical angle?
