Oral Radiology I BDNT 3337

Course description:

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 and periapical diseases are also among the topics to be studied in this course.Practical application in dental radiography lab and clinical setting are performed.

Course Aims:

The course aims to provide students with the principles of radiography, x-radiation protection, operation of x-ray equipment, infection control procedures, hazardous waste maintenance, practice in film exposure, processing, mounting and interpretation.

Course outcomes:

At the end of this course, the students will be able to:
  • Communicate the development of radiography in dentistry and its current application in the modern dental office.
  • Know how x-rays are produced, identify the component parts of the x-ray machine and its accessories and list and describe the possible interactions of x-rays with matter.
  • List and describe the different types of intra-oral and extra-oral x-ray films used in dentistry including their sizes, speeds as well as how to store them properly.
  • Know what is required to produce an ideal radiographic image and identify the quality of x-ray image regarding the radiographic density, contrast, sharpness, magnification and distortion.
  • Understand and practice the step-by-step procedures for both manual and automatic film processing.
  • Identify the anatomical landmarks as seen in radiographs, distinguish between abnormalities and normal variations.
  • Identify all radiographic errors and their specific method of correction. 
  • Demonstrate correct techniques basics and exposure for both film and imaging of intra-oral radiographs. 
  • Discuss the harmful effects of radiation, both the short and long-term effects, whether they are somatic or genetic.
  • Discuss the types and properties of digital radiography as a recent modality and the future of dental radiography.
