Radiographic Examinations: Choosing the Right Patients & Equipment
You will receive 1 unit(s) of continuing education credit upon successful completion of this course. The registration fee is only $41.00

This course was developed to limit radiation exposure by emphasizing that routine radiographic examinations are not warranted, and the decision to use radiography should be based on the patient’s health history, vulnerability to oral disease and the results of the clinical exam. Technical aspects of choosing and using equipment will be explored as well.

Learning Objectives:

Upon completion of this course, participants should be able to do the following:

  1. Explain the importance of limiting radiographic exposure.
  2. Understand the guidelines for selecting patients for radiographic exams.
  3. Use knowledge of patients’ dental and medical history, the results of clinical exams, the ALARA principle and the guidelines to appropriately use X-rays.

This course summarizes the recommendations of the American Dental Association in collaboration with the U.S. Food and Drug Administration released in December 2012 that describe implementation of proper radiographic practices related to patient selection and limiting radiation exposure. In addition, dentists should be aware of, and comply with, applicable federal and state regulations. Dentists should weigh the benefits of dental radiographs against the consequences of increasing a patient’s exposure to radiation and implement appropriate radiation control procedures.
