The lead apron must always be worn.The lead apron causes a triangular radiolucent area at the bottom center of the panoramic image.If this error occurs,the lead apron should be adjusted.This error is caused by the thyroid collar.A thyroid collar should not be worn while exposing a panoramic image.A lead apron with a thyroid collar causes a bilateral radiopaque artifact hat obstructs the mandible on a panoramic projection.A partial denture would cause ghost images.When the patient is slouched,slumped,or not standing with the shoulders back,the cervical spine appears as a radiopacity in the center of the image and obscures diagnostic information.
