A critical evaluation of xerocephalometry: absorbed dose and diagnostic information.
The present study showed that the thyroid (60X) and active bone marrow (100X) doses are increased when xeroradiography is used in cephalometrics, as compared to a rare earth screen/film system. These results are compared to previously published articles. The rationale for advocating a kVp setting of approximately 100 and a negative development mode is presented. It is recommended that xeroradiographic cephalometric examinations be reserved for special cases in which image quality is a top-priority requirement.
