DNH 130 - Oral Radiography for the Dental Hygienist (2 CR.)

Course Description

This course presents a study of physics, biology, safety, and exposure techniques for intra- and extra-oral radiographic surveys. Laboratory provides practice in exposure, processing methods, mounting, and interpretation of normal findings. Lecture 1 hours per week. Laboratory 3 hours per week. Total 5 hours per week.

General Course Purpose

This course provides students with the fundamental background and theory for the safe and effective use of x-ray radiation. Laboratory sessions emphasize the placement, exposing, processing, mounting, and interpretation of dental radiographs.

Course Prerequisites/Corequisites

Prerequisites: ENG 111, NAS 162, NAS 162, SDV 101. Corequisites: DNH 111, DNH 115, DNH 141.

Course Objectives

Upon completing the course, the student will be able to:

  • Discuss the principles of x-ray physics and x-ray production.
  • Discuss the characteristics and effects of x-ray radiation.
  • Discuss methods of radiation exposure and the importance of patient education.
  • Discuss the components, types, sizes, speeds, and uses of dental x-ray films.
  • Discuss the methods and the chemicals used for processing dental x-ray films.
  • Discuss the importance of quality assurance and quality control.
  • Describe and identify anatomical landmarks and structures of the maxillae and mandible.
  • Describe and identify radiographic anomalies and pathology.
  • Describe and recognize types of radiographic errors.
  • Describe and demonstrate basic positioning of the patient, x-ray film, and x-ray tube for the paralleling and bisecting angle techniques.
  • Demonstrate the ability to utilize the paralleling and bisecting angle techniques when exposing dental radiographs.
  • Demonstrate the ability to place, expose, process, mount, and interpret dental radiographs.
  • Demonstrate the ability to expose a full mouth series, a bite-wing series, and an occlusal survey on a manikin.
  • Demonstrate the ability to expose a full mouth series on adult patients.
  • Demonstrate the ability to expose a bite-wing series and a panoramic radiograph on a pediatric patient.
  • Demonstrate the ability to expose a panoramic radiograph on an edentulous or partially edentulous patient.
  • Discuss the importance for practicing proper methods of infection control when exposing and processing radiographs.
