DANB RADIOLOGY EXAMINATION TEST 2026
FULL SOLUTION GRADED A+
◉ The purpose of a bitewing image. Answer: Used to examine the
crown of both maxillary and mandibular teeth on one film. Mainly used
to locate interproximal caries.
◉ The purpose of a full mouth series. Answer: a series of intararal dental
images that show all tooth -bearing areas of both jaws. Consists of
periapical (vertical and horizontal) images and bitewings.
◉ The purpose of an occlusal x-ray. Answer: Used to examine large
areas of he maxilla or the mandible on one film.
◉ purpose of panoramic xray. Answer: shows a panoramic(wide) view
of the maxilla and mandible and surrounding structures on a single
image
◉ cephalometric xray. Answer: exhibits the bony and soft tissue of the
facial profile
◉ CBCT (cone beam computed tomography). Answer: Used to describe
computer assisted digital imaging in dentistry; this imaging technique
, uses a cone shaped x ray beam to acquire information and present it in
3D
◉ what patients should you watch histories for when using xrays?
Answer: A patient who is pregnant, on blood thinners, or are going thru
chemotherapy/radiation treatments.
◉ what to do if a patient is pregnant, on blood thinners, or going thru
chemo? Answer: Watch how much radiation theyre being exposed to.
*sometimes will wait till after pregnancy or chemo if they can*
◉ iItraoral parallel techniques. Answer: known as extension cone
paralleling technique
◉ Principle of intraoral parallel techniques. Answer: The receptor is
placed parallel to the long axis of the tooth. the central ray is
perpendicular to the receptor and long axis. A beam alignment device
MUST be used to keep the receptor parallel
◉ How is a receptor placed for parallel intraoral. Answer: Must be
positions to cover the prescribed area
◉ What is the position for a parallel intraoral. Answer: The receptor
must be parallel to the long axis
