Dental Hygienists - Expanded Functions


Delegation

Pursuant to IAC 650--Chapter 10, dentists may delegate expanded function duties to licensed dental hygienists if the hygienist has completed board-approved training in the specific expanded function that will be delegated. Certain restrictions and limitations apply. Please refer to IAC 650--Chapter 10 for specific requirements.


Documentation of Expanded Functions Training

All expanded function training must be properly documented to ensure compliance with Board rules. Documentation of training must be maintained by the dentist in the office of practice. The Board has developed a sample training documentation form

As a reminder, like all intraoral duties performed by registered dental hygienists, expanded function duties must be performed under the direct supervision of a licensed dentist. Direct supervision means the dentist has delegated the task and is present in the treatment facility.


Level 1 Expanded Functions

Level 1 procedures include:

      1.   Taking occlusal registrations for purposes other than mounting study casts;
      2.   Placement and removal of gingival retraction;
      3.   Fabrication and removal of provisional restorations;
      4.   Applying cavity liners and bases and bonding systems for restorative purposes; and
      5.   Taking final impressions.

Dental hygienists who complete training in all Level 1 expanded functions are Certified Level 1 expanded functions providers.  Dental hygienists must be a Certified Level 1 provider prior to completing training in Level 2 expanded functions.


Level 2 Expanded Functions

A dentist may delegate any of the Level 1 or Level 2 expanded function procedures to a dental hygienist who is a certified Level 2 provider.  Dental hygienists must successfully complete training for all Level 2 expanded function procedures before becoming certified Level 2 providers.

      1.   Placement and shaping of amalgam following preparation of a tooth by a dentist;

Expanded Functions Course Resource List

Board-approved courses are available for expanded function training. You may download and use these resources for the didactic and clinical/lab components. The initial assessment and postcourse competency assessment must be developed by the dentist and be available in the dental office as part of the documentation of training for that particular course. The other reference(s) may be used as a supplement for the didactic component.  Some of the approved courses are available in two formats, .html and .pdf. If you wish to download or print the courses for future use, the .pdf format is useful. When both formats are offered, you can select the format you prefer.

3. Fabrication and Removal of Provisional Restorations:

Board rules, which prohibit the delegation and removal of synthetic material, apply to permanent materials and do not prohibit the removal of temporary cement. In addition to those provisional restorations mentioned in the course materials, orthodontic brackets and bands are also included in the definition of a provisional appliance when referring to this Fabrication and Removal of Provisional Restoration course of study. Successful completion of the portion of this course that refers to the removal of supragingival temporary cement will authorize dental assistants to perform this function.
