What action is NOT permitted as part of the Level 1 expanded function for dental hygienists?

The action that is not permitted as part of the Level 1 expanded function for dental hygienists is diagnosing dental conditions. In the scope of practice for dental hygienists, particularly at Level 1, they are allowed to perform various tasks that support the delivery of dental care, such as taking radiographs or bonding orthodontic devices, under the supervision of a licensed dentist.

However, the diagnosis of dental conditions falls under the purview of the dentist. This is because diagnosing requires comprehensive clinical judgment and expertise that extends beyond the preventive and therapeutic procedures typically assigned to dental hygienists. Therefore, while hygienists play a crucial role in patient care, they are not authorized to make diagnoses; this responsibility remains with the licensed dental professional. Understanding this distinction is essential for maintaining professional boundaries and ensuring that care provided is within the legal framework of dental hygiene practice.
