amalgam and a full metal crown can be distinguished from each other radiographically by their
shape and margins
which of these dental restorative materials appears most radiopaque
amalgam
which of these dental restorative materials is most likely to mimic decay radiographically
composite
dens in dente appears radiographically as a
tooth within a tooth
a sharp bend in the tooth root is called
dilaceration
radiographically, it is not possible to accurately differentiate between a periapical abscess, a granuloma, and a cyst
radiographically it is not possible to accurately differentiate between carcinoma and sarcoma
both are true
which of these appears radiolucent on a radiograph
abscess
a large radiolucency surrounding the crown only of an unerupted tooth is most likely what type of cyst
dentigerous
the evidence of resorption that appears to shorten the tooth root is called
external resorption
the radiographic appearance of a small oviod radiopacity within the pulp chamber of the tooth is called a
pulp stone
which of the following appears radiolucent in its early stages as a radiopaque mass in later stages
pericapical cemental dysplasia PCD
which of the following tumors appears radiolucent radiographically
sarcoma
radiographic evidence of a bone fracture appears as a radiolucent line that may resemble a
nutrient canal
root canal material is
gutta percha
caries appear radiopaque, because more radiation is passing through the demineralization than the surrounding tissues
the first part of the statement is false, but the second part of the statement is true
each of the following will produce an ideal radiographic image for detecting caries except one
excessive vertical angulation
caries in the earliest stage is called
incipient
radiographs are best at detecting incipient caries of which of these locations on the tooth
proximal
the key to successfully interpretating radiographs for proximal surface caries is to examine the contact point between adjacent teeth and just apical to the
estimated gingival margin
proximal surface carious lesions appear
triangular
which of the following appears radiographically as a radiolucent notch that is less than half-way through the enamel
incipient proximal caries
which of the following appears radiographically as a radiolucent double triangle that is less than halfway through the dentin toward the pulp
advanced proximal caries
the key to successfully interpretating radiographs for occlusal caries is to examine
under the occlusal surface for changes in the dentin
which of the following appears radiographically as a round radiolucency in the middle of the tooth with well defined borders
buccal/lingual caries
which of the following appears radiographically as an ill-defined crescent-shaped radiolucency below the CEJ
cemental caries
caries that occur under a restoration or around its margins are called
recurrent caries
each of the following may mimic caries radiographically except...
stainless stain crowns
an optical illusion created by an increased radiolucency observed at the cervical area of the tooth is called mach banding
the mach banding effect increases when overlap error occurs
