This must be increased to keep receptor parallel with the long axis of the tooth.
What is object-receptor distance?
100
The central ray is directed downward at this vertical angulation.
What is +10 degrees?
100
Use words such as hurt, or "Oops"
What is DO NOT? Instead inform patients that the procedure will be momentarily uncomfortable.
100
A cotton roll must be place in the area of the missing tooth, or teeth, to support the tab or beam alignment device. This is the space where teeth are no longer present.
What is edentulous?
100
This type of dental radiograph utilizes extraoral technique, displays both upper and lower jaws in one film, and reveals normal anatomy, cysts, abnormal bone.
What is Panoramic?
200
Must be increased to ensure that only the most parallel will be directed at the tooth.
What is target-receptor distance?
200
Specifically used to examine the level of alveolar bone in the mouth and post Tx or follow up images for patients with bone loss due to periodontal disease.
What is vertical bite-wings?
200
Direct the central ray through the contact areas of the teeth, and align the opening of the PID parallel with the curvature of the arch.
What is DO?
200
Bony growths along the lingual aspect of the mandible. These may cause problems in receptor placement and a modification in technique is therefore necessary.
What is mandibular tori?
200
This dental radiograph uses the intraoral technique, displays one arch per film, and large areas of upper and/or lower.
What is Occlusal?
300
DANB placement for a molar periapical requires: Contact between molars open, 2-3 mm past the crowns, 2-3 mm past the apices, 4 mm past the second molar, and the distal half of this tooth.
What is second premolar?
300
This size of receptor is used to examine the posterior teeth of children with primary dentitions. This receptor is always placed with the long portion of the receptor in a horizontal direction.
What is size 0?
300
Set all exposure factors before placing any receptors in the mouth.
What is DO? Kilovoltage, millimaperage, and time.
300
Parallelism between the receptor and the long axis of the tooth is difficult to accomplish in a patient with this, also known as a low palatal vault.
What is a shallow palate?
300
This size receptor is used in the anterior region; long portion in the vertical direction.
What is size 1?
400
DANB placement for a premolar periapical requires: contact between premolars open, 2-3 mm past the crowns, 2-3 mm past the apices of the teeth, and distal of this tooth.
What is the canine?
400
When exposing this type of bite-wing, the anterior edge of the film should be placed at the midline of the mandibular second premolar.
What is molar bite-wing?
400
Use a definite order when exposing receptors to avoid errors and to make efficient use of time.
What is DO? Exposure sequence.
400
An incorrect horizontal angulation could result in this, you would need to adjust the PID positioning.
What is overlap, foreshortening, or elongation?
400
This size receptor is used in the posterior region; long portion in the horizontal direction.
What is size 2?
500
This type of image is recommended for the evaluation of an incisal crown fracture. It enables evaluation of the proximity of the pulp chamber to the fracture.
What is periapical image?
500
The bite-wing technique is a method used to examine this of the teeth.
What is interproximal surfaces?
500
Begin with the molar bite-wing exposure.
What is DO NOT? Instead, always begin with the pre-molar bite-wing; placement may cause patient to gag.
500
To check for these, stand directly behind the tubehead and look along the side of the PID. No portion of the receptor should be visible; the receptor should be covered by the opening of the PID.
What is cone-cut?
500
This dental radiograph is specific to Ortho, its extraoral technique shows the upper and lower jaw as well as a side view.
