Dental Hygiene Radiology
Exam Answer Key
Course Introduction
Dental Hygiene Radiology is an essential course that introduces students to the principles and practices of dental radiography as it pertains to dental hygiene care. The course covers the fundamentals of radiation physics, radiation safety, and infection control, as well as techniques for exposure, processing, and mounting of dental radiographs. Students will gain both theoretical knowledge and practical skills in taking intraoral and extraoral radiographs, interpreting radiographic findings, and identifying anatomical landmarks and common dental pathologies. Emphasis is placed on minimizing patient exposure while producing high-quality diagnostic images, fostering a comprehensive understanding necessary for effective and safe radiographic practices in a dental hygiene setting.
