Which density on CBCT is associated with restorations and metallic foreign bodies?

• A. Black
• B. Gray
• C. White
• D. Blue

Answer: (C)

High-density materials like restorations and metallic foreign bodies show up as white on CBCT because they are highly radiopaque and block most X-rays. Less dense tissues appear gray or black, with air being black and soft tissue gray; bone sits lighter gray-to-white but not as bright as metal. Blue isn’t a standard CBCT density in the typical grayscale display. So the density associated with restorations and metallic foreign bodies is white.
