Final answer:
Certain RDA procedures, like radiography, nitrous oxide administration, and coronal polishing, require certification. Each of these necessitate specialized training and demonstration of skills to ensure patient safety and quality of dental care.
Step-by-step explanation:
The Registered Dental Assistant (RDA) must obtain certification for certain procedures under the dental board of the specific state they practice in. These certifications often include radiography procedures, nitrous oxide administration, and coronal polishing, among other advanced duties. Not all duties require certification; however, for those that do, the RDA must demonstrate competency through formal education, testing, and sometimes a separate licensure.
For instance, to perform radiography procedures, RDAs must understand safe and effective operation of x-ray equipment, patient safety protocols, and image development. With nitrous oxide administration, they need to be trained on dosage, patient monitoring, and emergency procedures. Coronal polishing requires understanding of tooth anatomy, appropriate polishing techniques, and selection of prophylaxis agents. The goal is always to ensure patient safety and effective dental treatment outcomes.
