What causes scratched film appearance?

A scratched film appearance is characterized by the presence of fine white lines on the processed film, which can detract from the quality of the radiographic image. These white lines occur due to physical scratches on the film emulsion during handling or processing. The scratches disrupt the uniform surface of the film, preventing proper exposure to the x-rays and leading to areas that are consistently lighter compared to the rest of the image.

In this context, identifying white detailed lines as the cause of scratched film appearance highlights the significance of careful film handling and processing in dental radiography. This understanding reinforces the need for dental assistants to adopt appropriate techniques to minimize damage to radiographic films, ensuring better diagnostic quality.
