Questions and Answers

Which of the following is the purpose of film processing in dental radiography?

  • To create black, white, and gray areas on the radiograph
  • To preserve the image so it does not disappear
  • To remove the unexposed silver halide crystals
  • To convert the latent image into a visible image (correct)

What happens to the halide portion of the silver halide crystals during film development?

  • It is exposed to radiation
  • It is removed in a process known as reduction (correct)
  • It remains unaffected by the developer
  • It creates black, metallic silver appearance

Which areas on a dental radiograph appear dark (radiolucent)?

  • Areas with white or clear appearance
  • Areas where unexposed silver halide crystals are located
  • Areas with black, metallic silver appearance
  • Areas where x-rays were able to pass through to the film (correct)
