This module explains the physics and safe application of ionising radiation fundamental to dental radiology. Didactic lectures will cover radiation physics, radiation biology, radiation safety / protection, imaging theory, dental and maxillofacial radiographic techniques and interpretation of normal structures and common disease processes using radiographs. Students will learn about the different types of dental radiographic machines and the types of images they produce. The indications for the various types of radiographic image are explained together with their disadvantages.

Students will investigate geometric imaging theory, radiographic density and contrast and radiographic quality assurance. Development of competency in various radiologic technical skills will be expanded through supervised clinical practice in managing patients with varied oral and dental conditions. Technical proficiency in basic radiography is first developed working on manikins. Under direct supervision these skills are adapted to the clinical situation culminating in a clinical experience in radiographic technique and performance of a radiologic interpretation of the dental structures.

Students will be shown how to expose a radiograph and the law relating to the safe use of ionising radiation. The radiographic appearance of dental pathology will be explained and students will learn to recognise abnormal appearance. The student will develop independent judgment through written interpretation of full mouth, panoramic and other necessary radiographs and report on radiographic appearance to assist in diagnosis and treatment planning.
