What phenomenon can lead to the presence of black dots and lines on a panoramic radiograph?

• A. Static electricity
• B. Magnetic interference
• C. Radiation exposure
• D. Improper technique

Answer: (A)

The presence of black dots and lines on a panoramic radiograph is typically attributed to the effects of static electricity. Static electricity can create artifacts on x-ray films or digital images, resulting in unwanted marks and visual disturbances that can appear as small black dots or linear patterns. This is often caused by environmental factors such as low humidity, which increases the likelihood of static buildup on the film or sensor. When the imaging materials become charged, it can create discharges that manifest as these black dots and lines in the final image. Proper handling and storing of radiographic films, as well as maintaining appropriate humidity levels in the environment, can help to reduce or eliminate these artifacts during radiographic imaging. The other options, while they can affect radiographic images, do not specifically lead to the appearance of black dots and lines. Magnetic interference doesn't typically impact the quality of x-ray images in this way, and while unnecessary radiation exposure can affect the film's overall density or clarity, it does not create the specific artifacts described. Lastly, improper technique might result in other types of image distortion or clarity issues, but it is not specifically linked to the formation of black dots and lines caused by static electricity.
