Radiation absorbed from dental implant radiography: a comparison of linear tomography, CT scan, and panoramic and intra-oral techniques

摘要: Absorbed radiation dose in bone marrow, thyroid, salivary gland, eye, and skin entrance was determined by placement of lithium fluoride thermoluminescent dosimeters (TLD's) at selected anatomical sites within on a human-like x-ray phantom. The phantom exposed to from linear tomographic computer-assisted (CT) simulated dental implant radiographic examinations. mean for each site. Resulting measurements tomography are compared with reported panoramic intra-oral doses. CT examination delivered the greatest dose, while generally lowest. Panoramic doses were similar those tomography.
