Dental Assistant – LEVEL I AND II


High demand in the Dental Profession for appropriately trained personnel is the impetus for offering the 46 week Dental Assistant – Level I and II program.

In their assisting role with a Dentist, the Dental Assistant may prepare the treatment rooms; sterilize, disinfect and transfer dental instruments; assist with moisture control; expose, process and mount dental radiographs; inventory control; and prepare dental materials. Administrative training includes basic manual and computerized office procedures such as bookkeeping, dental insurance submission and appointment control.

The graduate may polish teeth; apply fluoride treatments; instruct patients in oral hygiene practices; place pit and fissure sealants; apply topical anesthetic; apply desensitizing agents; polish restorations; apply over the counter whitening agents; and take preliminary impressions for study casts.


Graduates of the Dental Assistant – Level I and II program will be eligible to write the National Dental Assisting Examining Board (NDAEB) examination. This will allow them to perform the intra oral duties in the dental office.

Once the graduate receives the NDAEB approval, they may then become Certified Dental Assistants by registering with the provincial membership association, Ontario Dental Assistants Association (ODAA). After which they will have the designation of Certified Dental Assistant II (CDA II). This certification is recognized throughout Ontario by many employers in the dental community.
