TEST PAPER PATIENT MANAGEMENT AND CARE
PLANNING REVIEW SHEET FULL SOLUTIONS
◉ What dose extraoral techniques optimize? Answer: -diagnostic
quality
-dose limitation
-diagnostic quality and dose limitation
◉ BWX exposure indications Answer: -examination of crowns and
crestal bone of both maxillary and mandibular teeth
-most frequent exposure
-typically posterior only
◉ Guiding principles Answer: -justificatiion of imaging procedure
-optimization of imaging procedure (greatest diagnostic yield with
the least radiation dose possible
◉ What type of BWX would you use for detecting carious lesions?
Answer: EO BWX
because of the overlap on IO BWX
,◉ When would CBCT be used? Answer: -implant placement
-endodontic assessment
-TMJ assessment
-orthodontic -evaluation of lesions and abnormalities
-extraction of impacted teeth
◉ Axial plane Answer:
◉ Multiplanar reconstructed images Answer: images viewed
together, axial, coronal, and sagittal images
◉ What are disadvantages to cone beam imaging? Answer: -cost of
equipment
-advanced training required to interpret data
◉ Cortical bone/compact bone Answer: -the dense outer layer of
bone
-appears radiopaque on an image
◉ Cancellous bone Answer: -soft, spongy bone located between two
layers of dense cortical bone
-"lattice-like" appearance
-appears primarily radiolucent
,◉ Process Answer: marked radiopaque prominence or projection
◉ Ridge Answer: radiopaque linear prominence or projection
◉ Spine Answer: radiopaque sharp, thorn-like projection
◉ Tubercle Answer: radiopaque small bump or nodule
◉ Tuberosity Answer: radiopaque rounded prominence
◉ Canal Answer: radiolucent tubelike passageway containing
nerves/blood vessels
◉ Foramen Answer: radiolucent opening or hole that permits
passage of nerves/blood vessels
◉ Fossa Answer: radiolucent broad, shallow, scooped out or
depressed area of bone
◉ Sinus Answer: radiolucent hollow space, cavity, or recess in bone
, ◉ Septum Answer: radiopaque bony wall or partition that divides
two spaces or cavities
◉ Suture Answer: radiolucent line that is an immovable joint that
represents a line of union between adjoining bones of the skull
◉ Alveolar crest in the anterior vs posterior Answer: anterior:
pointed/sharp
posterior: flat/smooth
◉ Alveolar process of the mandible Answer: portion of the mandible
that encases and supports the teeth
◉ Genial tubercles Answer: tiny radiopaque bumps of bone that
attach the genioglossus and geniohyoid muscle and located on the
lingual aspect of the mandible in.a ring inferior to the apices of the
mandibular incisors
◉ Lingual foramen Answer: radiolucent dot located near the midline
and on the lingual aspect of the mandible surrounded by the genial
tubercles
◉ Nutrient canals Answer: radiolucent tubelike passageways
through bone that contain nerves and blood vessels and seen in the
mandibular anterior region
