DHY 156 — Pre-Clinical Dental Radiology
introduces techniques for dental radiograph placement, exposure, imaging, and analysis. Students practice intraoral and extraoral radiographs on DXTTR mannequins, adhering to safety and protection guidelines. In preparation for clinical care, radiographic techniques are performed on peer partners without radiation exposure. These sessions also include patient education, infection control, screening and selection procedures, and radiology rotation duties. Radiographic techniques covered include paralleling, bisecting, localization, occlusal, panoramic, and panoramic bitewings. Students explore various intraoral sensors, positioning devices, and dental x-ray equipment. Radiographs are evaluated for anatomical accuracy and technique errors, with students self-assessing and applying corrective measures to produce high-quality diagnostic images.
