This course studies the basic physics and equipment behind the production of X-rays, their properties and interaction which results in the formation of the radiographic image. In addition, the radiographic techniques involved in producing various radiographic images and the x-ray films and other requirements for film processing are covered in this course. Radiation protection of patients and dental staff from the harmful effects of x-rays and interpretation of simple lesions as caries, periodontal, periapical, and intra-bony lesions are also among the topics to be studied in this course. These are presented through lectures, demonstrations, and practice in practical sessions.
