22-24 Flashcards
Each of the fallowing will produce an ideal radio graphic image for detecting caries except
Excessive elongation
Carries in the earliest stage are called
Incipient
Radiographs are best at detecting incipient caries of which location of the tooth
Proximal
The key to successfully interpretations radiographs for proximal surface caries is to examine the contact point between adjacent teeth and just apical to the
Estimated gingival margin
Proximal surface catfish lesions appear
Triangular
Which of the following appears radiographyally as radiolucent notch that is less then halfway through the enamel
Incipient proximal carries
Which of the following appears radio graphically as a radiolucent double triangle that is less than halfway through the Denton toward the pulp
Advanced proximal Carries
The key to success really interpreting radiographs for occlusal carries is to examine
Under the occlusal surface for changes in the Dentin
Which of the following appears radio graphically as a round radiolucent in the middle of the tooth with a well-defined borders
Buccal/lingual caries
Which of the following appears radioactively as an ill-defined crescent shaped radiolucent below the CEJ
Cement all carries
Carries that occur under a restoration or around it’s margins are called
Recurrent
Each of the following may mimic carries radiographically except
Stainless stain crowns
