Which entity governs registration requirements for dental assistants in Iowa?

• A. Iowa Department of Public Health
• B. Iowa Board of Medicine
• C. Iowa Dental Board
• D. Iowa Department of Public Safety

Answer: (C)

Registration requirements for dental assistants in Iowa are governed by the Iowa Dental Board. This board licenses and regulates dentistry and dental auxiliaries, setting who may work as a dental assistant, what credentials are needed, and the registration process itself. The Iowa Department of Public Health handles public health programs and other health licensing but not this specific registration. The Iowa Board of Medicine licenses physicians and medical professionals, not dental staff. The Iowa Department of Public Safety deals with safety and law enforcement, not dental practice regulation. So, the Iowa Dental Board is the correct regulator.
