What is a distinguishing feature of personal supervision as opposed to other types?

A distinguishing feature of personal supervision is that the dentist is present and actively engaged in the patient's care during the procedure. This level of supervision involves the dentist not only overseeing the activities being performed but also interacting with the patient, ensuring that they receive the appropriate level of care and support. Personal supervision provides an opportunity for immediate feedback and guidance, which enhances the safety and quality of the procedure being performed.

In contrast, the other options reflect different supervision types where the dentist's involvement may be minimal or absent. In scenarios where the dentist does not engage with the patient directly, they may still be supervising the procedure, but not in a manner that allows for immediate support. Similarly, when the dentist does not need to approve the completion of work or can be off-site, that indicates a lower level of oversight, which is typical of general or indirect supervision rather than personal supervision.
