California Registered Dental Assistant (RDA) Written Practice Exam

The role of cementing permanent crowns or bridges is highly regulated due to the complexity and clinical implications involved. The RDAEF, or Registered Dental Assistant in Extended Functions, is specifically trained and allowed to perform certain advanced procedures, including cementation of permanent crowns and bridges, under the supervision of a licensed dentist.

This added level of training enables the RDAEF to understand the materials and techniques required for this task, ensuring that the procedure is carried out safely and effectively. The legal framework governing dental procedures stipulates that such responsibilities must be performed by individuals who have received the appropriate certification and training for extended functions in dentistry.

While a dentist can certainly perform this task, and in some cases, a dental assistant may assist with procedures related to temporary crowns, the RDAEF is the only classification among the choices provided that has the legal capability to independently cement permanent restorations. Other professionals like the hygienist do not have the scope of practice necessary to perform this task on their own.
