In order to prevent a “ghost image,” you must instruct a patient to:

(1) The dental radiographer should present the doctor’s treatment plan to the caregiver who may accompany a patient with a disability to the appointment rather than directly to the patient.  (2) If the dental radiographer determines that a patient cannot tolerate intraoral projections, no intraoral receptors should be exposed.

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 _______

A.  Define radiolucent. B.  Describe the properties of structures or materials that appear radiolucent on dental images. C.  Explain why these structures or materials appear radiolucent on dental images.

A large, well-adapted radiopaque restoration with smooth borders is probably made of:

Identify the restoration on tooth #19.

CBCT scans may be interpreted by:

The proper vertical angulation of the PID for pediatric occlusal projections.  “The maxillary angulation is ____ degrees and the mandibular is ____ degrees.” Note: include positive or negative in your answers. _______ _______

Select all of the ways that CBCT imaging is similar to panoramic 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.
