Dental Assisting Radiology
Exam Preparation Guide
Course Introduction
Dental Assisting Radiology is an essential course designed to introduce students to the principles and practices of dental radiography. The course covers fundamental topics such as radiation physics, safety protocols, equipment operation, exposure techniques, and image processing. Students learn how to properly position patients, handle dental radiographic equipment, and produce high-quality diagnostic images while adhering to strict infection control and radiation safety standards. Emphasis is placed on understanding the interpretation of radiographs, recognizing normal and abnormal anatomical structures, and maintaining legal and ethical responsibilities in radiology. Hands-on laboratory experiences complement theoretical learning, preparing students to confidently assist dentists in various radiographic procedures within a clinical setting.
