Which procedure is included in the scope of practice for dental hygienists concerning teeth?

The procedure that falls within the scope of practice for dental hygienists is root planing. This is a fundamental part of periodontal therapy and involves the thorough cleaning of the root surfaces to remove plaque and tartar from the teeth, particularly below the gumline. This procedure is essential for the treatment of gum disease and helps to promote healing of the periodontal tissues.

Dental hygienists are trained to perform various preventive and therapeutic services, which include scaling, root planing, and providing patient education on oral hygiene practices. This skill set is critical for maintaining oral health and preventing further disease progression.

In contrast, filling cavities and extracting teeth are procedures that typically require a dentist's specialized training and licensure. Diagnosing oral diseases also falls primarily within the dentist’s scope, although dental hygienists can identify signs of disease and refer patients for further evaluation. Thus, root planing is clearly aligned with the responsibilities and training of dental hygienists within their professional practice.
