Sagittal (S-upper row) and axial (A-lower row) scans of (a) a tooth with enamel caries pointed by the arrow, the same tooth next to the (b) amalgam restoration, (c) metal-ceramic restoration, and (d) porcelain crown. In images b(S) and b(A), a metal artifact (arrow) caused by amalgam is seen as a radiolucent area resembling dentin caries. In image c(S), the artifact (arrow) caused by metal-ceramic restoration is seen as an area with high attenuation, covering the carious lesion. In image c(A), streak-artifact (arrow) caused by metal-ceramic restoration is seen as a lucent area resembling dentin caries
