MULTIPLE CHOICE
1. Radiation is defined as
A. A form of energy carried by waves or streams of particles.
B. A beam of energy that has the power to penetrate substances and record
image shadows on a receptor.
C. A high-energy radiation produced by the collision of a beam of electrons
with a metal target in an x-ray tube.
D. A branch of medicine that deals with the use of x-rays.
ANSWER: A
Radiation is a form of energy carried by waves or streams of particles. An x-
ray is a beam of energy that has the power to penetrate substances and
record image shadows on a receptor.
X-radiation is a high-energy radiation produced by the collision of a beam of
electrons with a metal target in an x-ray tube. Radiology is a branch of
medicine that deals with the use of
X-rays.
Option B specifically refers to x-rays, which is a form of radiation, but it is
not the broad definition of radiation itself.
Option C describes a specific mechanism of producing x-rays, but it doesn’t
capture the overall concept of radiation.
Option D refers to radiology, the branch of medicine dealing with x-rays, but
again, it's not the definition of radiation itself.

2. A radiograph is defined as
,A. A beam of energy that has the power to penetrate substances and record
image shadows on a receptor.
B. A picture on film produced by the passage of x-rays through an object or
body.
C. The art and science of making radiographs by the exposure of an image
receptor to x-rays.
D. A form of energy carried by waves or a stream of particles.
ANSWER: B
An x-ray is a beam of energy that has the power to penetrate substances and
record image shadows on a receptor. A radiograph is a picture on film
produced by the passage of x-rays through an object or body. Radiography is
the art and science of making dental images by the exposure of a receptor to
x-rays. Radiation is a form of energy carried by waves or streams of particles.
Option A describes x-rays (the energy beam), not a radiograph.
Option C refers to radiography, which is the process of creating radiographs,
but it does not define a radiograph itself.
Option D refers to radiation, which is the energy source for creating
radiographs, but is not the definition of a radiograph.

3. Your patient asked you why dental images are important. Which of the
following is the correct response?
A. An oral examination with dental images limits the practitioner to what is
seen clinically.
B. All dental diseases and conditions produce clinical signs and symptoms.
C. Dental images are not a necessary component of comprehensive patient
care.
D. Many dental diseases are typically discovered only through the use of
dental images.
ANSWER: D
An oral examination without dental images limits the practitioner to what is
seen clinically. Many dental diseases and conditions produce no clinical signs
and symptoms. Dental images are a necessary component of comprehensive
, patient care. Many dental diseases are typically discovered only through the
use of dental images.
Option A is incorrect because dental images enhance, rather than limit, a
practitioner’s ability to make a diagnosis. They allow the practitioner to see
beyond what is visible to the eye.
Option B is incorrect because not all dental diseases present clinical signs
and symptoms, especially in the early stages. Dental images are crucial for
detecting these hidden problems.
Option C is also incorrect because dental images are a necessary component
of comprehensive patient care, helping the dentist provide an accurate
diagnosis and appropriate treatment plan.

4. The x-ray was discovered by
A. Heinrich geissler
B. Wilhelm roentgen
C. Johann hittorf
D. William crookes
ANSWER: B
Heinrich geissler built the first vacuum tube in 1838. Wilhelm roentgen
discovered the x-ray on november 8, 1895. Johann hittorf observed in 1870
that discharges emitted from the negative electrode of a vacuum tube
traveled in straight lines, produced heat, and resulted in a greenish
fluorescence. William crookes discovered in the late 1870s that cathode rays
were streams of charged particles.
Option A is incorrect because heinrich geissler created the first vacuum tube
in 1838, but he did not discover x-rays.
Option C refers to johann hittorf, who made important contributions to the
study of cathode rays and observed that discharges from the negative
electrode of a vacuum tube could produce fluorescent light, but he did not
discover x-rays.
Option D refers to william crookes, who also made significant contributions to
the study of cathode rays and discovered that they were streams of charged
particles, but he did not discover x-rays.
