Questions and Answers

What is the aim of film processing in oral and maxillofacial radiology?

  • To ionize the silver halide molecules
  • To expose the dental radiograph to x-ray photons
  • To produce an invisible image on the dental radiograph
  • To convert the invisible latent image on the film into a visible image (correct)

    • What happens to the latent image at the time of exposure?

  • The bromide ions escape from the emulsion
  • The unexposed silver halide molecules form the latent image
  • The metallic silver atoms turn into bromine gas
  • The silver halide molecules absorb x-ray photons and undergo ionization (correct)

    • What constitutes the latent image in film processing?

  • Metallic silver atoms and bromine gas
  • Silver specks formed in crystals without silver halide molecules
  • Exposed ionized silver halide molecules and unexposed silver halide molecules (correct)
  • Emulsion and bromide ions
