Abstract

- The magnitude of projection errors, calculated theoretically on length measurements in cephalometry was studied. Rotation of the object by up to 5° from the proper position, resulted in errors in length measurements that were usually less than one percent. Rotations of more than 5° may increase the error but imply misalignments of the head that should be evident when positioning the patient. The advantage of extremely long focus film distances seems doubtful.
