Final answer:
Unlicensed Dental Assistants under general supervision may carry out preparatory and auxiliary dental procedures that are low-risk and routine, aimed at increasing dental office efficiency.
Step-by-step explanation:
The question pertains to the scope of practice for an unlicensed Dental Assistant (DA) under the general supervision of a licensed dentist. Basic supportive dental procedures that an unlicensed DA may perform typically involve tasks that do not require the professional skill and judgment of a licensed dentist. These procedures are generally preparatory or auxiliary in nature, such as setting up patient and instrument trays, sterilizing instruments, and possibly taking dental impressions or radiographs if permitted under state regulations. The treatments tend to be routine, have a low risk associated with them, and are designed to increase the efficiency of the dental office by relieving the dentist of tasks that do not necessarily require their advanced expertise.
