and neck region.
b) removal of eyeglasses.
c) specific directions as to performing the
scan while teeth are slightly apart.
d) all of the above.
9) Viewing software allows the practitioner to select the region of interest and to scroll through these
images on a computer monitor to create three-dimensional information that will assist in:
a) diagnosis and treatment planning.
b) referrals. c) obtaining insurance reimbursement.
d) all of the above.
10) The specialized equipment necessary for three-dimensional imaging that accepts the raw data and
converts it to a stack of axial images called DICOM images is called the:
a) computer.
b) control panel. c) imaging hardware.
d) CBCT machine.

CHAPTER PRETEST ANSWERS
1) d
With the use of three-dimensional digital imaging, the dentist now has the ability to evaluate
pathology and discern distances to critical anatomic landmarks with more detailed information,
5) c
In 1999, a technology termed cone-beam computed tomography (CBCT) was introduced that allows
for the viewing of structures in the oral-maxillofacial complex in three dimensions.

CRITICAL THINKING QUESTION
Ms. Candice Miles is a patient in your office and is scheduled for a three-dimensional image to
begin her implant treatment. How will you explain the procedure to her?
Discussion Guidelines: The three-dimensional reconstruction and radiographic image have imaging
capabilities comparable to a CT scan, but offer higher resolution with a much lower radiation dose to the
