Dental Radiography DENT 9282


Our Dental Radiography course is designed for professionals (including nurses, receptionists, and dental assistants) currently employed in a dental practice in Ontario or graduates of a dental office administration program who wish to be qualified to meet the requirements of the Healing Arts Radiation Protection (HARP) Act. Study the theoretical, legal, and practical applications involved in exposing, processing, and handling dental radiographs while focusing on provincial/federal regulations, radiation hygiene measures, and standard intraoral radiographic techniques. Practice using various intraoral radiographic techniques in order to produce radiographs of diagnostic value while learning to follow radiation safety protocols and processing procedures. Additional instruction is provided in recognizing and solving faulty radiographs and the identification of normal radiographic landmarks as well as client management.

Passing this course means you have met all the requirements set out by the HARP Act and are qualified to operate an x-ray machine in the province of Ontario.


Course Delivery:

Although this course mostly uses a self-directed online format, there will be two days at the end of the course when you will be required to come to campus to do the practical portion. These two days will be done over a weekend, and you will be able to select the weekend you attend from a few options.


You must be currently working in a dental office and you must have completed our DENT 9271 Dental Anatomy (Online) course or our EX 9010 Dental Anatomy Challenge Exam (Online) course. Internationally trained professionals who have already earned a diploma/degree in the dental field are eligible to register even if they are not currently working in a dental office.
