How are caries differentiated from nonmetallic radiolucent restorations radiographically?
What will be an ideal response?
Caries usually have more diffuse borders and an uneven triangular radiolucency with the apex pointing toward the DEJ or pulp. To aid in distinguishing a restoration from caries, look for the restoration to have straight borders, and a prepared look, with an overall even radiolucency. A clinical exam may be needed to make a definitive determination.
