34
As lesion progresses and dentin is affected, translucent enamel may show gray discolored dentin on marginal ridges
Interproximal caries
35
In enamel, radiolucency (frequently triangular) with base at proximal surface near contact point
Interproximal caries
36
In dentin, radiolucency (frequently triangular) with base at DEJ

37
What's the best radiographic exam to detect carious lesions?
Bitewings for posterior teeth PAs for anterior teeth
38
On this type of radiograph, carious lesions are usually only seen when large enough to be clinically apparent
Pano

47
T/F: X-Rays underestimate the actual depth of the lesion
True
48
Superficial layers of non-cavitated lesions may remineralize
Arrested carious lesion
49
Are arrested carious lesions discernible on X-Rays?
No, but activity may be monitored radiographically
50
How do you monitor the activity of a lesion?
Take an X-Ray that day, and then a second image at another time
