Final answer:
In dentistry, a Registered Dental Assistant is allowed to fabricate temporaries intraorally under both general and direct supervision of a dentist, with the distinction being the dentist's physical presence during the procedure.
Step-by-step explanation:
A Registered Dental Assistant (RDA) is permitted to fabricate temporary crowns or bridges intraorally under either general or direct supervision of a dentist. Under general supervision, an RDA can perform the task without the dentist being physically present in the office, provided the dentist has given the instructions for the procedure. Under direct supervision, the dentist must be present in the office while the task is being performed, ready to provide assistance if necessary.
Task delegation in dental practices varies by jurisdiction, and it is important for the RDA to be familiar with the local regulations. RDAs are typically responsible for various supportive procedures that contribute to the quality care of dental patients. Aside from fabricating temporaries, RDAs might also assist in other procedures such as taking and reporting vital signs, preparing solutions, sterilizing equipment, and assisting the dentist during treatments.
