Under which circumstance can a dental hygienist with an initial limited license perform subgingival scaling?

A dental hygienist with an initial limited license can perform subgingival scaling under the condition that they have received prior instruction from a licensed dentist. This requirement is in place to ensure that the dental hygienist operates within the scope of their training and the legal stipulations of their limited license. It ensures that the procedures performed are necessary and appropriate for the patient’s condition as determined by a licensed professional.

This protocol not only protects the patient by ensuring they receive care based on a dentist’s clinical judgment but also supports the dental hygienist's training by reinforcing their role as an integral part of the oral healthcare team under the supervision and guidance of a dentist. Therefore, receiving instruction from a dentist is vital for the hygienist to carry out more advanced duties such as subgingival scaling, which requires clinical insight regarding the dental health status of the patient.

Subgingival scaling is a specific therapeutic procedure often indicated for periodontal disease management, and the dentist's direction before this procedure helps tailor the treatment to the particular needs of the patient, enhancing both safety and efficacy.
