Case Study #35Case Study #35No, the correct answer is that this film was placed backward in the patient's mouth, creating this "tire-track pattern." It can also exhibit a "herringbone" effect. The film appears light and has this pattern because the side of the film that has the lead foil was placed directly next to the area that was exposed in the radiograph.
Remembering to place the white side of the film next to the area to be exposed will eliminate this problem.
