What causes discrete black lines to appear on the radiograph?
What will be an ideal response?
Bending the film or excessive pressure can cause the emulsion to crack, resulting in black lines. Films should not be bent to fit the oral cavity. The radiographer must exercise caution when placing films into the film-holding device and when handling them in the darkroom to avoid accidentally bending the film.
