Dental Hygiene Radiology
Pre-Test Questions
Course Introduction
Dental Hygiene Radiology is a foundational course designed to familiarize students with the principles and practices of dental radiography. The course covers the theory and application of radiographic techniques, including the safe operation of radiographic equipment, interpretation of radiographic images, and the implementation of infection control protocols. Students learn about the biological effects of radiation, radiation protection methods, film processing, digital imaging, and the identification of normal and abnormal anatomical structures. Emphasis is placed on patient safety, accurate imaging, and effective communication of findings within the scope of dental hygiene practice.
