Registered Dental Assistant (RDA) Law and Ethics Practice Exam

Which of the following best defines a dental assistant?

1. A licensed individual who can perform all procedures

2. An unlicensed person performing basic supportive procedures under supervision

3. An individual responsible for financial matters in a dental office

4. A dental professional overseeing patient treatment plans

The correct answer is: An unlicensed person performing basic supportive procedures under supervision

A dental assistant is best defined as an unlicensed person performing basic supportive procedures under supervision. This definition accurately reflects the role of a dental assistant, as their primary responsibilities include assisting the dentist in clinical procedures, preparing instruments, and managing patient care while working under the direction and supervision of a licensed dentist. While dental assistants provide essential support in the dental setting, they operate within the confines of their training and the legal responsibilities outlined in dental practice acts. This means they cannot perform advanced procedures that require licensure and specialized education. Other roles mentioned, such as overseeing treatment plans or managing financial matters, fall outside the primary duties and scope of practice for dental assistants. Therefore, understanding that dental assistants are primarily involved in supportive functions under supervision helps clarify their role within the dental team.
