When a full mouth series of periapical images is prescribed for an edentulous patient, why is a 14 image FMX, and not an 18 image FMX, the appropriate prescription. 

If the dental radiographer determines that a patient cannot tolerate intraoral projections, no intraoral receptors should be exposed.

Structure #28 (between the small black arrows) is:

Structure #21 is:

The process of informing patients about the particulars of exposing dental images is termed:

For each clinical situation, identify the most appropriate imaging exam.  Select your answer from the following choices: periapical image bite-wing image panoramic image occlusal image CBCT scan A.  a very frightened and traumatized 3-year-old who has fallen and fractured E and will barely open his mouth  _______ B.  preliminary evaluation of impacted third molars _______ C.  evaluation of a suspected periapical abscess #30 _______ D.  evaluation of eruption patterns, growth, and development of a 12-year old with a family history of supernumerary teeth _______ E.  determining the endodontic working length during a root canal procedure on #8 _______ F.  identifying incipient interproximal decay _______ G.  initial examination of a patient with generalized severe interproximal bone loss _______ H.  most accurate assessment of alveolar bone prior to implant placement _______

(1) Three-dimensional imaging provides a slightly less accurate image than traditional two-dimensional imaging. (2) Locations, distances, sizes, and shapes of pathology and anatomic landmarks, including eruption patterns, are more accurately represented with two-dimensional imaging.

(1) Confirming with a patient their tendency to gag during imaging procedures is a recommended and proactive patient management strategy.  (2) If a patient does gag, keep the receptor in place and calmly but firmly instruct the patient to continue to bite down and try again.

CBCT scans may be interpreted by:

When using the bisecting angle technique to expose mandibular teeth, the vertical angulation of the PID must be set to a _______ angulation and to a _______ angulation for exposing the maxillary teeth.
