Registered Dental Assistant (RDA) Law and Ethics Practice Exam

What procedures may a DA/RDA/RDAEF perform under direct supervision?

1. Only extraoral duties

2. Coronal polish and topical fluoride application

3. Only pit and fissure sealants

4. Emergency procedures without supervision

The correct answer is: Coronal polish and topical fluoride application

The answer is correct because under direct supervision, a Dental Assistant (DA), Registered Dental Assistant (RDA), or Registered Dental Assistant Extended Functions (RDAEF) is allowed to perform specific procedures that contribute to patient care while still working under the oversight of a licensed dentist. Coronal polishing and the application of topical fluoride are commonly accepted duties that these professionals can perform, provided a dentist is present in the office and can check the quality of the work as needed. Direct supervision means that the supervising dentist must be in the office, and they must authorize and oversee the procedures being performed. Coronal polishing and fluoride applications are essential preventative treatments that help maintain oral health, and the allowance for assistants to perform these tasks helps streamline dental work and provides effective care to patients. For the other procedures mentioned, such as only performing extraoral duties or only pit and fissure sealants, these do not capture the full scope of duties permitted under direct supervision. Emergency procedures without supervision is not accurate since emergency situations still typically require oversight by a licensed dentist for safety and legal compliance. Understanding the scope of practice for dental assistants in these areas is crucial for fulfilling their professional responsibilities within the law.
