Which duty can a dental hygienist perform under general supervision?

A dental hygienist can perform patient education in oral hygiene under general supervision because this activity does not require any direct or immediate supervision from a dentist. General supervision allows dental hygienists to educate patients about maintaining proper oral hygiene, including brushing techniques, flossing, and dietary advice related to oral health, without needing the dentist to be present in the office.

On the other hand, soft tissue curettage, restoration placement, and administering local anesthesia typically require direct supervision of a dentist. These procedures involve more complex clinical skills or interventions that necessitate the oversight of a dentist to ensure patient safety and procedural correctness, reflecting the legal and ethical responsibilities associated with higher-risk dental tasks.
