DENTAL RADIOLOGY LATEST EXAM ACTUAL 2026/2027
QUESTIONS AND SOLUTIONS RATED A+
✔✔Mylohyoid Ridge - ✔✔Below apices of the molars
✔✔External Oblique Ridge - ✔✔
✔✔Submandibular Fossa - ✔✔below roots of mandibular molar
✔✔Mandibluar Canal - ✔✔
✔✔Bisecting Angle Technique - ✔✔Central Ray is directed perpendicular to an
imaginary line which bisects the long axis of the tooth and the film
✔✔Least amount of film in FMS - ✔✔14
7-Max
7-Mand
✔✔Vertical Angulation (BAT) - ✔✔The opening of the cone is vertically parallel to the
bisector
✔✔Horizontal Angulation (BAT) - ✔✔The opening of the cone is horizontally parallel to
the angle of the arch of the teeth to be exposed
✔✔Cone cut prevention (BAT) - ✔✔Front and back: Cone is 1/4'' anterior to the film.
Top and bottom: Cone is 1/4'' above (maxillary) or below (mandibular) the occlusial
plane.
✔✔5 most common errors in technique - ✔✔foreshortening
elongation
horizontal overlap
cone cutting
excessive bending
✔✔ Parallel Technique - ✔✔1) Long axis of tooth and film are parallel to eachother
2) The central ray is directed perpendicular to the long axis of the tooth and film
✔✔Periapical Film - ✔✔Used to show root apex of tooth and surrounding structures
✔✔Bitewing exposure - ✔✔Used to detect interproximal decay and height of alveolar
bone
✔✔Occlusial - ✔✔Used to view cross section of the teeth and complete palatal structure
or floor of mouth
