Course Description:

Picture of mannequin having radiographs takenOur Dental Radiology course is approved by the Technologist Certification Section of the Bureau of X-Ray Compliance (in turn a part of the NJ Department of Environmental Protection) and is designed to prepare students to take the exam that will lead to becoming a Licensed Dental Radiologic Technologist (LDRT).  In other words, you'll have an x-ray license to perform dental-specific procedures.  You may also see the phrase Limited Dental Radiologic Technologist, which refers to the fact that you are limited to performing only dental-specific radiological procedures as opposed to performing radiological procedures on other parts of the human body.

The course is broken down into three components:
  1. A didactic component
  2. A laboratory component
  3. A clinical component

The didactic component

The didactic (or instructional) component is the more traditional classroom time.  It is here that you will first be introduced to the required radiology concepts and practices that you will need to know and be able to perform in order to obtain your license.  In this part of the course students will learn about radiation physics, radiation biology, exposure and processing techniques, radiation safety, processing chemicals, and mounting films.  Students will spend a total of 30 hours in a classroom setting and will receive a thorough course manual that will aid in studying and preparing for DANB's  [DANB Disclaimer]RHS  [DANB Disclaimer]exam discussed below.  Course manuals are provided in class.  

The laboratory component

The laboratory component of this course is designed to provide students a truly hands-on opportunity to practice their newly learned skills.  You will practice actual procedures with real instruments, equipment, and live radiation using a mannequin as your patient.  Students will expose actual radiographs (x-rays) and later process (develop) those radiographs.  Students will however, not be allowed to practice exposing films on each other.  A total of 20 hours are allotted to laboratory time.  

The clinical component

This clinical component of the course can only begin after completion of the first two components (the didactic and laboratory components).  The "clinical" must be performed in a state approved (Bureau of X-Ray Compliance approved) dental office where you are supervised by a properly licensed individual.  If you are already working in a dental office you may be able to use your current employer to complete your clinical, pending approval.

New regulation from New Jersey's Bureau of X-Ray Compliance requires that prospective students obtain an agreement with a dental office where they can and plan to complete their clinical component before being permitted to register or enroll in a state-approved dental radiology program.

Many dental offices may not yet be familiar with this new regulation. Dental Assistant Services has provided a form that helps to summarize the recent regulatory changes to dental offices and dentists. We encourage you to print out and take this form with you when asking a dental office for permission to complete your clinical at their site. Should the office have any questions or concerns, please encourage them to call our office at 732-919-1816. We'd be happy to explain the new regulations.

Exposing a radiographThe entire course runs for a total of 22 weeks and ends with the student being fully prepared to take the Dental Assisting National Board's (DANB's  [DANB Disclaimer]) Radiation Health & Safety (RHS  [DANB Disclaimer]) exam that will lead to your becoming a Licensed Dental Radiologic Technologist.  Put another way, this course will leave you fully prepared to take the exam that will lead to your dental x-ray license.

After obtaining a NJ dental x-ray license most dental assistants will begin working on their Certified Dental Assistant (CDA  [DANB Disclaimer]) certificate.  One of the requirements for becoming a CDA certificant is to pass DANB's  [DANB Disclaimer]RHS  [DANB Disclaimer]exam.  If you complete all of the other requirements to become a CDA certificant within five years (which is certainly realistic), having passed the RHS exam now in order to become a Licensed Dental Radiologic Technologist will exempt you from having to take the RHS exam a second time as part of earning your CDA certification.

Students who are pregnant or who may become pregnant are allowed to take the full radiology course including both the laboratory and clinical components.  Upon becoming aware of your pregnancy, Dental Assistant Services will provide you with a written pregnancy policy as mandated by the Department of Environmental Protection.

The purchase of a separate textbook will be required for this course.  The required book is called "Dental Radiography: Principles and Techniques" (4th edition).  It is written by Joen M. Iannucci and Laura Jansen Howerton and was published by Elsevier in 2011.  The ISBN number is 1437711626. 

We encourage you to shop around online for the best price.  Click here for a list of some useful websites that may assist with locating a textbook.  At times we may have used textbooks from previous students available for sale.  Please call to find out if there are any used copies currently available.
