Expanded Functions


Pursuant to IAC 650--Chapters 10 & 20, dentists may delegate expanded function duties to licensed dental hygienists and registered dental assistants if the practitioner has completed board-approved training in the specific expanded function that will be delegated. Certain restrictions and limitations apply. Please refer to IAC 650--Chapters 10 & 20 for specific requirements.

Expanded functions are now divided into two categories, Level 1 and Level 2 expanded functions procedures.  

Level 1 Expanded Functions

Registered dental assistants and licensed dental hygienists may choose to train in any of the Level 1 expanded functions procedures.  It is not a requirement that training be completed in all level 1 procedures unless a practitioner chooses to do so. Practitioners may pick and choose in which of the Level 1 functions that they receive training.  

Registered dental assistants and licensed dental hygienists who complete training in all Level 1 expanded functions are Certified Level 1 expanded functions providers.  Registered dental assistants and licensed dental hygienists must be a Certified Level 1 provider prior to completing training in Level 2 expanded functions.

Level 2 Expanded Functions

Registered dental assistants and licensed dental hygienists who choose to complete training in Level 2 expanded functions must complete training in all Level 2 expanded functions procedures.  Unlike Level 1 procedures, practitioners do not have the option to pick and choose the Level 2 procedures in which they complete training.  

Registered dental assistants and licensed dental hygienists who complete training in Level 2 expanded functions are Certified Level 2 expanded functions providers.  A dentist may delegate any of the Level 1 or Level 2 expanded function procedures to a registered dental assistant or licensed dental hygienists who is a certified Level 2 provider.  

Expanded Functions Training Approval

Pursuant to IAC 650--Chapter 20, expanded function training shall be eligible if the training has been prior-approved by the Board.  The training may include on-the-job training offered by a Iowa-licensed dentist. If you wish to submit an expanded functions training course for approval, you may find an expanded functions training approval request form here.

In order to be eligible for approval, expanded functions training courses must consist of the following:

1.   An initial assessment to determine the base entry level of all participants in the program. At a minimum, participants must be currently certified by the Dental Assisting National Board or must have two (2) years of clinical dental assisting experience as a registered dental assistant;
2.   A didactic component;
3.   A laboratory component, if necessary;
4.   A clinical component, which may be obtained under the personal supervision of the participant’s supervising dentist while the participant is concurrently enrolled in the training program; and
5.   A post-course competency assessment at the conclusion of the training program.

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 in the office of practice. The Board has developed a sample training documentation form.

Continuing education credit hours will be awarded for completion of courses as specified.

Expanded Functions Training Providers

The following providers have been approved to provide training in all Level 1 expanded functions.  Approved expanded functions training courses are available to both dental assistants and dental hygienists who wish to train in expanded functions.

The Board has also approved courses that are available for in-office expanded functions training.  You may download and use the 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.  Please note: These training materials and contact information for other training providers that have been approved for specific procedures will be provided on the pages detailing the information for each auxiliary type.
