Questions and Answers

What is the main cause of the 'Back side film projection (Herring bone defect)' error?

  • Improper handling of the X-ray machine
  • Incorrect exposure time
  • Wrong development process
  • Film is projected with its back side (correct)

    • How should the 'Printed dot artifact' error be corrected or overcome?

  • Film should be repositioned
  • Embossed dot should be placed apically (correct)
  • Exposure time should be increased
  • Development process should be adjusted

    • How can the 'Distortion' error be corrected or overcome?

  • Modify the X-ray machine settings
  • Adjust the development process
  • Instruct patient to just support the film without excessive bending (correct)
  • Increase the exposure time

    Study Notes

    Intraoral Radiography Errors

    • Back side film projection (Herring bone defect): Main cause is the film packet being placed backwards in the patient's mouth.
    • Printed dot artifact: Caused by the presence of dots on the film packet, correction involves using a new film packet or replacing the old one.
    • Distortion: Corrected by using a parallel technique, ensuring the X-ray beam is perpendicular to the film, and the film is placed parallel to the tooth.
    • Crowns cut off: Main cause is the beam not being centered over the film, resulting in the crown being cut off from the radiograph.
    • Black line: Caused by the film being bent or curved, correction involves using a new film packet or straightening the film.
    • Blurred image: Caused by patient movement or incorrect exposure time, corrected by taking a new radiograph with the patient held still and adjusting exposure time.
    • RO artifact: Corrected by adjusting the X-ray beam angle, ensuring it is perpendicular to the film, and using a parallel technique.
    • Phalangioma: Caused by the patient's finger or thumb being in the primary beam, corrected by keeping the patient's hands away from the beam.
    • Double image: Caused by the patient moving during the exposure, corrected by taking a new radiograph with the patient held still.
    • Dropped film corner: Caused by the film packet not being securely placed in the holder, corrected by ensuring the film packet is securely held in place.
    • Apices cut off: Corrected by adjusting the X-ray beam angle, ensuring it is perpendicular to the film, and using a parallel technique.
    • Area of interest not shown: Caused by the film not being placed correctly, corrected by ensuring the film is placed in the correct position to capture the area of interest.
