Dental Radiography Exam Preparation Guide
Course Introduction
Dental Radiography is a course designed to introduce students to the fundamental principles, techniques, and safety protocols involved in obtaining and interpreting dental radiographic images. The curriculum covers the physics of X-ray production, radiographic anatomy, patient positioning, film and digital imaging technologies, infection control, and radiation protection measures. Students gain hands-on experience in operating dental radiographic equipment, conducting intraoral and extraoral exposures, and assessing image quality for accurate diagnosis and treatment planning. Emphasis is placed on ethical and legal considerations, record keeping, and maintaining patient comfort and safety throughout radiographic procedures.
