RDA Law and Ethics Practice Exam 2026 – Complete Prep Guide

The correct understanding of what procedures a Registered Dental Assistant (RDA) can perform without a dentist present is that they are limited to only those procedures explicitly allowed by state law. This is essential because each state has specific regulations governing the scope of practice for dental assistants, which dictates what procedures can be performed independently.

State laws ensure that patient safety and professional standards are maintained within the dental practice. For instance, certain tasks might require supervision or be entirely restricted to licensed dentists, while others may be permitted for registered dental assistants when certain conditions are met.

The notion that RDAs can perform any procedures they have been trained for does not hold, as not all training aligns with legal authorization, highlighting the importance of understanding state laws in determining allowable procedures. Similarly, suggesting that routine procedures not involving anesthesia are universally permitted overlooks the need for regulation and supervision in specific contexts. Limiting procedures to children only is inaccurate because RDAs work with patients of all ages, within the bounds of the law.

Ultimately, it's critical for RDAs to be aware of and operate within the scope defined by their state's laws, ensuring compliance and the highest standard of care in dental practice.
