What is a key condition for a dental hygienist to provide services without direct supervision?

A key condition for a dental hygienist to provide services without direct supervision is that the dentist must have provided a written treatment plan. This requirement ensures that the hygienist is operating within a clearly defined scope of practice and is adhering to the protocols set by the supervising dentist. A written treatment plan confirms that the dentist has assessed the patient's needs and has outlined specific procedures that the hygienist is authorized to perform independently.

This provision upholds patient safety and care standards, facilitating a collaborative approach to dental services where the hygienist can effectively contribute to patient management while still following the dentist's clinical directives. It helps maintain consistent quality of care and ensures accountability, as the hygienist is acting based on a plan that has been evaluated and approved by a licensed dentist.
