What does static electricity cause in dental radiography?

• A. Distortion of the anatomical structures
• B. Black marks on the film
• C. Loss of image resolution
• D. Excessive radiation exposure

Answer: (B)

Static electricity is a phenomenon that can lead to the accumulation of electrical charges on surfaces. In the context of dental radiography, one of the most common effects of static electricity is the formation of black marks on the radiographic film. These marks are typically the result of sparks created by the discharge of static electricity, which can occur when the film is handled or stored in dry environments. When static electricity discharges onto the film, it can create artifacts that appear as dark streaks or spots, directly affecting the film’s appearance. This type of interference does not affect the anatomical structure's representation or cause loss of resolution. Instead, it specifically impairs the visual integrity of the film and can lead to misinterpretations if one is not aware of these artifacts. Proper handling and storage techniques can significantly reduce the likelihood of static-related issues, ensuring clearer images for diagnostic purposes.
