A dental hygienist with an initial limited license can perform which of the following procedures?

A dental hygienist with an initial limited license in Washington State is authorized to perform specific procedures that align with their training and the scope of practice defined by state regulations. Subgingival scaling is among the procedures that fall within the scope of practice for dental hygienists, including those with limited licenses.

This task involves the removal of calculus and plaque from below the gum line, which is a fundamental aspect of maintaining oral health and preventing periodontal disease. The emphasis on preventive care and the management of periodontal conditions is central to the role of a dental hygienist, making this procedure suitable for those at the initial stages of their professional licensing.

In contrast, procedures such as crown preparation, complex restorative work, and root canal therapy typically require a higher level of training and, therefore, are reserved for licensed dentists. These tasks involve more extensive intervention and expertise in dental surgery and restorative procedures, which go beyond the scope of practice for dental hygienists, particularly those with an initial limited license. This distinguishes subgingival scaling as the correct choice for the procedures a dental hygienist with an initial limited license can perform.
