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.
