Introduction
The Florida Dental Radiography Certification Examination evaluates the knowledge
and clinical judgment required to safely expose dental radiographs while complying
with current professional standards, radiation safety principles, infection prevention
protocols, and Florida regulations governing dental auxiliaries. Candidates are
expected to demonstrate competence in patient assessment, equipment operation,
image quality evaluation, radiation biology, digital imaging systems, documentation,
and quality assurance. The examination emphasizes clinical application rather than
memorization, requiring candidates to analyze patient scenarios, identify appropriate
corrective actions, minimize radiation exposure, and produce diagnostically
acceptable images while maintaining patient safety, legal compliance, and ethical
standards expected in modern dental practice.
Question 1
A patient requires a full-mouth radiographic examination. Which action best satisfies
the ALARA principle while still obtaining diagnostically acceptable images?
,A. Increase exposure time to avoid retakes.
B. Prescribe images based on individual clinical findings and use appropriate
exposure settings.
C. Always obtain a panoramic image in addition to a full-mouth series.
D. Use the highest available tube current for all patients.
Correct Answer: B
Explanation: ALARA requires limiting radiation exposure by prescribing radiographs
based on clinical need while using appropriate exposure factors and proper
technique to minimize retakes.
Question 2
During placement of a digital sensor for a mandibular molar periapical image, the
patient reports discomfort due to a shallow floor of the mouth. What is the most
appropriate response?
A. Force the sensor into the ideal position.
B. Modify placement while maintaining correct angulation whenever possible.
C. Increase vertical angulation to compensate for poor placement.
D. Expose the image despite improper positioning.
Correct Answer: B
Explanation: Patient comfort should be balanced with proper positioning. Minor
adjustments help obtain diagnostic images while reducing discomfort.
Question 3
,Which tissue demonstrates the greatest radiosensitivity according to the Law of
Bergonié and Tribondeau?
A. Mature skeletal muscle
B. Rapidly dividing hematopoietic tissue
C. Dense cortical bone
D. Mature nerve tissue
Correct Answer: B
Explanation: Rapidly dividing, poorly differentiated cells are the most sensitive to
ionizing radiation.
Question 4
A bitewing radiograph shows overlapping interproximal contacts throughout the
image. Which technical error most likely caused this result?
A. Excessive vertical angulation
B. Incorrect horizontal angulation
C. Excessive exposure time
D. Improper receptor size
Correct Answer: B
Explanation: Incorrect horizontal angulation prevents the X-ray beam from passing
through contact areas, producing overlap.
Question 5
, A digital image consistently appears lighter than expected despite correct
positioning. Which exposure adjustment is most appropriate?
A. Decrease exposure time further.
B. Increase exposure time slightly.
C. Increase horizontal angulation.
D. Increase object-to-receptor distance.
Correct Answer: B
Explanation: Underexposed digital images may require a modest increase in
exposure while avoiding unnecessary patient dose.
Question 6
The primary purpose of rectangular collimation is to:
A. Increase image sharpness only.
B. Reduce patient radiation exposure.
C. Increase X-ray beam intensity.
D. Shorten processing time.
Correct Answer: B
Explanation: Rectangular collimation significantly reduces exposed tissue volume
and patient dose.
