RHS DANB Exam 2026/2027 questions and answers with
complete solutions verified latest update
Periapical Purpose to examine the entire tooth (crown and root)
and supporting bone, 3-4mm beyond root
apex
Bitewing purpose to detect interproximal carries, includes crown
and alveolar bone levels
Full Mouth Series for new patients, gets every surface, crown,
purpose and apex of each tooth
Occlusal purpose to show large areas of the maxilla and
mandible; supplemental view
panoramic purpose wisdom tooth impaction, jaw bone anomalies,
ortho
CBCT (cone beam computed a three dimensional digital imaging method
tomography) that used a cone shaped beam of radiation
that rotates around the patient; for complex
dental procedures and facial evals
Paralleling Technique reduces shape distortion and radiation
ala-tragus line imaginary line from the ala (wing) of the nose to
, the ear meatus (center)
positive vertical angulation The PID is positioned above the occlusal plane
and the central ray is directed downward
What is apical pathology? A condition affecting the apex of a tooth root,
often associated with infection or
inflammation.
What are caries? Cavities or decay in teeth caused by bacterial
infection that leads to the demineralization of
tooth structure.
What are dental anomalies? Irregularities in the development of teeth, such
as supernumerary teeth, which are extra teeth
beyond the normal count.
