The absorbed dose from radiographic examinations of adult patients using extra-oral dental radiography as lateral-oblique and postero-anterior views was examined. The absorbed dose at various sites in the head and neck was measured with thermoluminescent dosimeters (TLD). The maximum absorbed dose for both radiographic views is located at the point of entry. The absorbed doses in the various sites are compared and discussed in both techniques.
