Description

Overview of common dental procedures, such as composite, amalgam, partials, dentures, root canals, dental implants, crown and bridge appointments; manipulation of dental materials commonly prepared or used by the dental assistant, including impression materials, cement bases and liners, composites, and amalgams. Intended for students in the Dental Assisting Apprenticeship Program; enrollment is limited to students accepted in the program.
