Course Description

This intensive two-week hybrid (online and clinical component) course trains dental assistants in the fundamentals of dental radiography. Approved by the Massachusetts Board of Registration in Dentistry, the successful completion of this course will render the Dental Assistant qualified to expose radiographs in practices located in the Commonwealth of Massachusetts.  

The Dental Radiology Certificate Program will explore the basics of dental radiology, including x-ray physics, characteristics of radiation, the dental x-ray machine, effects of radiation exposure, radiation protection, image receptors, digital radiography, dental radiographic anatomy, and intra and extra-oral radiographic procedures. Students will gain experience exposing digital radiographs and correctly mounting them using a digital mount. This experience will be gained by hands-on exposure on a manikin and hands-on placement on both a manikin and lab partner. A final laboratory competency consists of exposure and evaluation of a full mouth series on a live patient selected by the student.

Course Objectives

Upon completion of this introductory course in dental radiology, each student will be able to:

  1. Identify normal anatomical landmarks in periapical, bitewing, occlusal and panoramic radiographs.
  2. Consistently produce acceptable diagnostic bitewing, periapical, occlusal and panoramic radiographs.
  3. Discuss the scientific principles that govern radiographic techniques including radiation physics, radiation characteristics, radiation biology, and radiation safety techniques, including the ALARA principle.
  4. Appreciate and guard against the dangers of x-radiation.
  5. List and explain the selection criteria for prescribing dental radiographs.
  6. Compare and contrast intra-oral and extra-oral radiographs and identify their purposes and uses in dental disease identification.
  7. Manage dental patients competently during clinical radiographic procedures.
  8. Determine common radiographic errors that cause poor radiographic quality and be able to correct those errors.
  9. Describe a diagnostically acceptable radiograph.
  10. Interpret radiographs and be able to distinguish normal anatomy from oral pathologies, caries, and periodontal diseases.
  11. List and explain state and federal laws that pertain to the practice of dental radiography.
  12. Explain the purpose, technique, and benefits of digital radiography.
  13. Describe the techniques and purpose of using localization techniques in radiology.

Students will be awarded a certificate upon successful completion of all course requirements.


  1. Must be at least 18 years old
  2. Must be currently working as a Dental Assistant
  3. Must provide a copy or current license in good standing
  4. Students are required to submit Immunization / Immunity Documentation Requirements prior to the first day of training:

Required Health Clearance    
Due 2 weeks prior the start of classes

Tuberculosis Screening: must be obtained within 3 months of the start of clinical rotations and annually thereafter. Students must receive either two-step Mantoux testing (PPD) or IGRA-serology (T-SPOT or Quantaferon Gold).  Two-Step Mantoux test: The purpose of the two-step PPD is to rule out a false negative on the first test.  Step 1: PPD implanted into forearm and 48-72 hours later, the student will have the test “read” and results are documented by the clinician.  Step 2: One to three weeks later, a SECOND PPD is implanted into the forearm and 48-72 hours later, the student will have the test “read” and results are documented by the clinician.

If the student has a positive PPD or IGRA screening, a chest x-ray must be obtained within 4 months of the start of the program and the chest x-ray report must be submitted to the Health and Wellness Center with a Positive Tuberculosis Test Questionnaire. The questionnaire is required to be completed annually for all students with positive tuberculosis screening.

Immunization/Immunity Records:

  • tetanus, diphtheria, and pertussis (TDaP) vaccination required within the past 10 years
  • hepatitis B – evidence of three vaccinations, immune titer results, or signed hepatitis B waiver required

    TITERS: If a titer is drawn, the student is required to submit the lab report to the Health and Wellness Center. Any result that is negative/indeterminate/equivocal will be considered a negative result and the student will be required to be revaccinated with the complete series of vaccinations for which a negative titer is received.
