Which of the following statements is true regarding the types of filtrations used in the dental x-
ray tube head?
Inherent filtration takes place when the primary beam passes through the aluminum disks in
the path of the x-ray beam between the collimator and the tube head seal in the dental x-ray
machine.
Machines operating above 70 kV require a minimum total of 2.5 mm aluminum filtration.
Inherent filtration alone will meet the standards regulated by state and federal law.
Filtration is used to restrict the size and shape of the x-ray beam and to reduce patient
exposure.
Machines operating above 70 kV require a minimum total of 2.5 mm aluminum filtration.
Identify the function of the collimator:
to restrict the size and shape of the x-ray beam
,to remove the long wavelengths from the x-ray beam
to remove the low energy x-rays from the beam
to increase scatter radiation
to restrict the size and shape of the x-ray beam
Identify which of the following is used to make a collimator:
aluminum
copper
lead
tungsten
lead
In the occlusal technique a size __ image receptor is used for adults, and a size __ receptor is
typically used for children.
2; 0

,2; 4
4; 2
4;2
The occlusal technique is used:
to detect interproximal caries.
when the placement of intraoral receptors is too difficult for the patient.
if a simple extraoral view is desired.
for evaluation of the temporomandibular joint.
when the placement of intraoral receptors is too difficult for the patient.
Identify one use for the occlusal image:
localize foreign bodies
diagnose dental caries
evaluate periodontal conditions
, examine lesions of the mucosa
localize foreign bodies
Which of the following is exclusively a mandibular occlusal technique?
pediatric
topographic
lateral
cross-sectional
cross-sectional
Identify the receptor size and vertical angulation required to expose a maxillary pediatric
occlusal projection on a 5-year-old child:
size 2 receptor; +60 degrees
size 2 receptor; -60 degrees
size 2 receptor; +90 degrees
size 4 receptor; +90 degrees
