the radiograph used to assess the patients skeletal profile and structure is
cephalometric
x ray beam missed part of the film
cone cutting
dark film image is a result of
developing solution being too warm and overdeveloping
duplication of a radiograph requires
duplicating film, duplication machine, and processing method
the technique error caused by not having enough angulation is
elongation
too little positive angulation for maxillary, or negative for mandibular
elongation
labial mounting is when the depressed dot is toward the operator as if the operator is viewing the films from the inside out
false
radiation exposure times are the same for children as for adults
false

foreshortening
in the developing solution, which chemical blackens the exposed silver halide crystals
hydroquinone
when mounting films, the term used when placing the dot towards the operator is called
labial mounting
the dental specialists who routinely use extraoral radiographs are
oral surgeons and orthodontists
which dental specialty routinely uses the cephalometric radiograph
orthodontics
incorrect horizontal angulation results in
overlapping
in the paralleling technique, the film packet must be
parallel to the long axis of the tooth
film is not completely immersed or tanks are low solution levels
partial image

exposing radiographs is a skill that requires proper technique each and every time
true
the paralleling technique must use a film holding device
true
to recheck your film positioning, the dot on the film is to be towards the occlusal/ incisal surface
true
light film image is a result of
underexposure and underdeveloping
in which position should the patient be placed for a bitewing radiograph
upright
