What is this course?

This course is an abbreviated version of the Radiology course approved by the Bureau of X-Ray Compliance (which is part of the NJ Department of Environmental Protection).  Unlike the state approved radiology course, this course does not include a laboratory or clinical component and is not sufficient for someone seeking a dental x-ray license for the first time.  Those new to the field and interested in a NJ dental x-ray license should take our state approved Radiology course.

Who should take this course?

If you need to take the Dental Assisting National Board's (DANB's  [DANB Disclaimer]) RHS  [DANB Disclaimer]exam, but do not need to take a NJ state approved course for the purposes of obtaining a NJ dental x-ray license you may want to consider taking this self-study course.

In order to become a Certified Dental Assistant (CDA  [DANB Disclaimer]) certificant you must pass three DANB  [DANB Disclaimer]exams.  The three exams are: Radiation Health & Safety (RHS  [DANB Disclaimer]), Infection Control, and General Chairside.  Most of our students will become a licensed dental radiologic technologist (get their dental x-ray license) before working towards their CDA certification.  As part of the requirements for obtaining a dental x-ray license in NJ, the majority of our students will have already taken DANB's RHS exam.  For those who fall into other categories, such as those discussed below, we offer this course as an alternative.

This course is not a requirement for obtaining your CDA  [DANB Disclaimer]certificate, while passing DANB's  [DANB Disclaimer]RHS  [DANB Disclaimer]exam is a requirement.  If you've already taken and passed the RHS exam you probably do not need to take it again.  However, the three DANB exams (RHS, Infection Control, and General Chairside) must all be taken and passed within a five year period.  Thus if you received your dental x-ray license more than five years ago you will have to (re)take the RHS exam in order to earn your CDA certification.

You may want to take this course if you fall into one of the following categories:

Course Description:

This course consists of a large and thorough self-paced study manual that covers the material you would obtain in the didactic (or instructional) component of the full state approved Radiology course.  It is designed to help you prepare to pass the DANB  [DANB Disclaimer]RHS exam  [DANB Disclaimer].

Picture of a dental radiograph The study manual covers a number of different topics including: film types, production of radiation (physics), components of the x-ray unit, exposing radiographs, techniques (bisecting, paralleling, occlusal, and panoramic), digital exposures, film processing, radiation safety, film mounting, anatomic landmark, radiation infection control, and quality assurance.

Each subject area is followed by a brief test.  At the end of the manual are a series of three final exams with 100 questions each where you can further test your knowledge and assess where your strengths and weaknesses may lie.  You are thus given several opportunities to take practice tests and assess your own progress.  Yes, the answers are also included.

Private Tutoring:

Private tutoring is available for this course only.  If you have read through the manual and are still confused or have questions, if you're the type of person that simply isn't self-motivated and needs a sense of accountability, or if you simply learn better by meeting with someone in person but do not want to take the full Radiology course, you may be interested in private tutoring.

Tutoring sessions are one-on-one and allow you the personal time and attention you may be seeking.  Tutoring is self-led, meaning that you should come prepared in advance with questions and that you control the topic of discussion.  Private tutoring is not meant as a replacement for a class where a curriculum (outline of topics to be discussed) is prepared for you in advance.  Tutoring is provided by Angelo Gallego, Jr., who is both a licensed diagnostic radiologic technologist and a licensed dental radiologic technologist.  Please contact Angelo directly to schedule an appointment.

Becoming a CDA Certificant

In order to become a CDA  [DANB Disclaimer]certificant you will need to meet the following requirements:
  1. You must show documentation of having earned a high school diploma in the United States or its equivalent.
  2. Once you feel ready you can complete an application to take either the full CDA  [DANB Disclaimer]exam in one four-hour session or you may take each of the three component exams separately.  The three component exams (or the three parts of the full exam) are:
    1. Radiation Health & Safety
    2. Infection Control
    3. General Chairside
  3. You must have and show documentation of 3500 hours of experience (in no less than two and no more than a four year period at some point in your career.) working as a dental assistant and a valid CPR certificate before you can sit for and take the General Chairside Exam.
  4. When your application has been successfully processed, a DANB  [DANB Disclaimer]letter entitled "Test Admission Notice" will be mailed to you.  At this point you can schedule your exam.
  5. After successfully passing either the full CDA  [DANB Disclaimer]exam or the three separate component exams you will receive an official score report in the mail.  When you have met all of the requirements, you will automatically be mailed a CDA certificate.  If you choose to take the exams separately you must complete all three within a five year period.  You do not need to apply separately for your actual CDA certificate after passing the full exam or the three component exams.
The process of obtaining a CDA  [DANB Disclaimer]certificate can be confusing as there are several components, several options, and multiple applications.  At Dental Assistant Services we try to simplify the process as much as possible.  We've been through the process several times and are here to offer you the benefit of our experience.  We will not simply teach you the course content and send you on your way.  We understand the process and how confusing it can be, and will actually take the time to walk you through that process.
