The focal trough of all panoramic radiographic machines is three-dimensional.

Question

Quizplus · Accepted Answer

The focal trough of panoramic radiographic machines is a three-dimensional curved zone where the patient's teeth and jaws must be positioned to produce a clear image. This is because panoramic radiography captures a broad view of the dental arches, and the focal trough ensures that all parts of the image are in focus despite the varying curvature of the jaws. Therefore, the statement is true.
