A Registered Dental Assistant (RDA) is a licensed oral healthcare professional who works alongside a dentist to provide clinical care, patient education, and administrative support. Because they hold state-recognized licensure, RDAs possess an expanded scope of practice allowing them to perform more advanced clinical tasks than a standard dental assistant. Core Responsibilities
RDAs manage a wide variety of advanced clinical and patient care duties:
Advanced Clinical Procedures: Applying pit and fissure sealants, placing temporary crowns, taking final teeth impressions, and performing coronal polishing.
Radiography & Diagnostics: Exposing, processing, and evaluating diagnostic dental X-rays.
Chairside Assisting: Utilizing four-handed dentistry to pass instruments, manage suction, and assist in complex oral surgeries.
Patient Care & Safety: Sterilizing surgical instruments, recording medical histories, tracking vital signs, and teaching proper oral hygiene. RDA vs. CDA: Key Differences
While both roles require professional credentials, they differ by jurisdiction and scope:
