What level of supervision is applicable for RDAs and RDHs performing expanded functions?

General supervision is the correct level of supervision applicable for registered dental assistants (RDAs) and registered dental hygienists (RDHs) when performing expanded functions. Under general supervision, licensed dental professionals are allowed to perform specific tasks and functions without the direct oversight of a dentist present in the treatment facility.

This means that while the dentist must have authorized the specific task, they do not need to be present in the office or directly supervising the procedure as it is being performed. This level of supervision is designed to allow RDAs and RDHs to work more independently and efficiently, utilizing their training to perform tasks that are within their scope of practice.

In many states, including Iowa, the distinction between supervision types is crucial for understanding the roles and responsibilities of dental professionals. Direct supervision, for instance, requires the dentist to be on-site and supervising the procedure in real-time. Indirect supervision entails the dentist being available for consultation but not necessarily present, and observational supervision is not a recognized form of supervision in this context. Each type has different implications for the responsibilities and autonomy of dental support staff and practitioners.
