Chapter 32: Identification of Restorations, Dental Materials & Foreign Objects Flashcards

Principles and Description of Restorations, Dental Materials and Foreign Objects

1
Q

Define the term: metallic restoration

A
  • restorations that completely absorb x-rays; as a result, little to no radiation contacts the receptor (appears radiopaque)
  • (ex: amalgam, gold)

Q

Define the term: radiopaque

A

the portion of an image that is light or white, due to the structure resisting the passage of the x-ray beam and limiting the amount of x-rays that reach the receptor
