In the state of California, who is legally permitted to perform coronal polishing?

  1. Only dentists

  2. Licensed RDA or RDAEF

  3. Dental hygienists only

  4. Student dental assistants

The correct answer is: Licensed RDA or RDAEF

In California, the legal framework governing dental procedures, including coronal polishing, specifies that only certain licensed professionals can perform this task. Licensed Registered Dental Assistants (RDA) and Registered Dental Assistant in Extended Functions (RDAEF) are authorized to perform coronal polishing, provided they have received the appropriate training and certification. This regulation is in place to ensure that individuals performing coronal polishing have the necessary skills and knowledge to do so safely and effectively, preserving the health and safety of patients. This involves understanding the anatomy and physiology of the teeth, as well as the proper techniques and equipment to use during the polishing process. While dentists and dental hygienists have broader scopes of practice, the specific designation of coronal polishing is granted to those with RDA or RDAEF licenses. Other options, such as student dental assistants and non-licensed individuals, cannot legally perform these functions until they obtain the necessary licensure, thereby ensuring compliance with California's dental practice laws.
