Which is a requirement under general supervision?

Under general supervision, one of the primary characteristics is that the dentist does not need to be physically present when the procedure is being performed. This allows dental auxiliaries, such as hygienists or dental assistants, to carry out certain procedures or tasks as directed by the dentist, without the dentist being onsite. It is important for the dentist to have established a treatment plan or given prior authorization for the specific procedures to be carried out.

This concept provides flexibility in the delivery of dental care, allowing for efficient use of resources and time, particularly in busy practices. Since the presence of the dentist is not required, it enables trained personnel to perform their duties effectively while still adhering to the dentist's guidelines and scope of practice.

In contrast, the other choices reflect different levels of supervision that are not applicable under general supervision. For instance, when a dentist must be available on the premises, this indicates direct supervision. Furthermore, the notion that only minor procedures can be performed pertains to the types of procedures commonly allowed under indirect supervision, where a dentist oversees but does not need to be present. The requirement for written consent is also an important aspect of dental practice but does not specifically define the conditions of general supervision.
