Registered Dental Assistant (RDA) Law and Ethics Practice Exam

Which of the following is a conditional duty that an RDA can perform?

1. Removing excess cement with an ultrasonic scaler from supragingival surfaces

2. Performing duties of an ortho assistant permitholder

3. Performing duties of a dental sedation assistant permitholder

4. Applying pit and fissure sealants

The correct answer is: Removing excess cement with an ultrasonic scaler from supragingival surfaces

The task of removing excess cement with an ultrasonic scaler from supragingival surfaces is recognized as a conditional duty that an RDA can perform under certain circumstances. This duty typically requires specific training and is contingent upon the availability of a licensed dentist to oversee the procedure. RDAs are permitted to carry out specific functions that enhance patient care and improve the efficiency of dental procedures while ensuring compliance with existing regulations. The ability to use an ultrasonic scaler for cleaning duties is a practical example of how RDAs can contribute to patient treatments as long as they are trained and the procedure is performed under proper supervision. Other tasks listed, such as performing duties of an ortho assistant permitholder or a dental sedation assistant permitholder, involve special permits or licenses that may not simply be granted based on RDA training. Additionally, applying pit and fissure sealants typically requires specific certification beyond the standard duties of an RDA. This context underscores why the first option is the valid choice concerning conditional duties an RDA can perform.
