The teaching mission of our section is to educate dental students about the physics of radiology, biologic hazards attendant to the use of ionizing radiation, radiation oncology, radiographic examinations such as intra/extra-oral radiography, panoramic radiography, contrast radiography, CT, MRI and sonography, and interpretation of these images. Also, We provide with education about clinical diagnosis and clinical management for diseases in maxillofacial bones and soft tissue such as salivary glands, neck and oral mucosa in collaboration with oral pathologists and oral surgeons. Our section (radiology department in our hospital) is equipped for computed radiographic system for conventional radiography, CT, MRI, sonography and digital fluoroscope system. We save all images except for intra-oral radiographs into an image server and send these images to other departments in our hospital through local network. Also, we are active in consulting on radiographic diagnosis from medical or dental offices in the community. The research programs in our section range from development of e-learning system to clinical research concerning about diagnosis of oral and maxillofacial diseases.
