Before exposing a panoramic radiograph on a patient, which item should not be removed?

When preparing a patient for a panoramic radiograph, it is essential to ensure that any items that could interfere with the imaging are removed to obtain a clear and accurate image. However, a watch is typically allowed to remain on the patient because it does not interfere with the radiographic process.

Watches are usually made of materials that do not significantly absorb radiation or create artifacts in the radiograph. Their position on the wrist is also far enough away from the area being imaged so that they do not obstruct or distort the view of the dental structures.

In contrast, items like dentures, eyeglasses, and earrings can introduce artifacts or shadows on the radiograph, obscuring important details. Therefore, these items should be removed before taking the panoramic image to ensure the highest quality resultant radiograph. By keeping the watch on, the technician adheres to best practices for patient comfort and diagnostic accuracy.
