Dental Assistants > Expanded Functions

Delegation

Pursuant to IAC 650--20.3(3), “a dentist may delegate an expanded function duty to a registered dental assistant if the assistant has completed board-approved training pursuant to rule 20.15(153) in the specific expanded function that will be delegated.” Certain other restrictions and limitations apply.

Expanded Functions Training Approval

Pursuant to IAC 650--20.15(153), expanded function training shall be eligible for Board approval if the training is offered through an ADA-accredited program or other program, which has been prior approved by the Board. The training may include on-the-job training offered by a Iowa-licensed dentist. You may find an expanded functions training approval request form here.

Training 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 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 postcourse 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 by the dentist in the office of practice. The Board has developed a sample documentation of training form. Click on the link to download this form.

As a reminder, like all intraoral duties performed by registered dental assistants, 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.

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.

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

4. 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 Restoriation 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.
