Which of the following tasks is NOT allowed by a Dental Assistant under general supervision?

A dental assistant working under general supervision has specific tasks they are permitted to perform as outlined by California dental regulations. Under these regulations, certain procedures are restricted to licensed dentists or more advanced dental professionals.

When it comes to polishing amalgam restorations, this task is considered more complex and requires a higher level of skill and understanding of dental materials and their implications in clinical practice. Thus, it is not permitted for a dental assistant to perform this task under general supervision.

On the other hand, tasks like placing orthodontic separators, testing pulp vitality, and drying canals fall within the scope of what dental assistants can do, even under general supervision, provided they have the necessary training and oversight.

Understanding these distinctions is crucial for maintaining compliance with dental laws and ensuring the quality of patient care. The differentiation between these tasks is primarily based on the level of skill required and the potential complexity associated with each procedure.
