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. Which one is the EXCEPTION? |
Excessive vertical angulation |
|
|
Caries in the earliest stage is called |
Incipient |
|
|
Radiographs are best for 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 margins |
|
|
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 dentin. |
|
|
Which of the following appears radiographically as a rounded 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 one. Which one is the EXCEPTION? |
Stainless steel crowns (Book Answer: Stainless stain crowns- Think it's a typo) |
|
|
An optical illusion created by an increased radiolucency observed at the cervical area of the tooth is called mach bonding. The mach bonding effect increases when overlap error occurs. |
The first statement is false. The second statement is true. |
