Registered Dental Assistant

Dental assistants perform a variety of patient care, office and laboratory duties. They work chairside with dentists as they examine and treat patients. They make patients as comfortable as possible in the dental chair, prepare them for treatment, expose dental radiographs and obtain dental records.

Assistants pass and retrieve instruments as well as restorative and impression materials to dentists and assist with fabrication and cementation of temporary restorations. Assistants also sterilize and disinfect instruments and equipment, prepare tray setups for dental procedures and instruct patients on post operatic and general oral health care. Extended duties include front office, laboratory and supply/inventory management procedures.

Dental Assisting is offered in the fall and spring on Northeast Campus.
