What defines general supervision in a dental setting?

General supervision in a dental setting is characterized by the dentist providing instructions to dental hygienists or dental assistants while not being physically present during the procedures being performed. This level of supervision allows for flexibility in care delivery as registered dental hygienists (RDHs) can work independently in the operatory while following the guidelines and protocols established by the supervising dentist.

This arrangement supports an efficient workflow whereby dental hygienists can carry out routine procedures, such as cleanings and assessments, based on the dentist's previously outlined instructions. The benefit of this system is that it enables hygienists to contribute effectively to patient care without the constant presence of a dentist, thus optimizing the use of time and resources in a dental practice.

In contrast, the other options describe different forms of supervision. For example, requiring the dentist to be present during the procedure characterizes direct supervision, while needing to check in regularly or approving every aspect of the procedure hints at a more involved form of supervision rather than the autonomy granted under general supervision.
