DENTAL BOARD[650]

Adopted and Filed

Rule making related to expanded functions

The Dental Board hereby amends Chapter 10, "General Requirements," and Chapter 23, "Expanded Functions," Iowa Administrative Code.

Legal Authority for Rule Making

This rule making is adopted under the authority provided in Iowa Code section 147.76 and chapter 153.

State or Federal Law Implemented

This rule making implements, in whole or in part, Iowa Code chapter 153.

Purpose and Summary

These amendments update the rules related to expanded functions. The amendments lower the clinical practice requirement following registration for dental assistants to train in expanded functions and provide greater flexibility to train in the functions. The rule making moves some of the Level 2 expanded functions to Level 1 designation for the purposes of training. Additionally, the rule making allows individuals to train in Level 2 expanded functions without the requirement to first complete training in all Level 1 expanded functions. The amendments include one amendment to Chapter 10 to reflect an earlier change to Chapter 23 and Iowa Code section 153.38.

Public Comment and Changes to Rule Making

Notice of Intended Action for this rule making was published in the Iowa Administrative Bulletin on September 7, 2022, as ARC 6515C. The Board accepted written comments through September 30, 2022. The Board received ten written comments. Six of the comments supported the changes that were drafted and in instances commended the Board for attempting to address access to care and staffing needs, particularly in rural areas. Four of the comments expressed concerns with some sections of the proposed rule making. One of the commenters preferred that the rules related to Level 2 expanded functions be left as they were. One of the commenters, who provides expanded function training, offered suggestions for revision to some of the expanded functions, including the number of hours required for training in each area. Additionally, the commenter expressed a preference to eliminate the initial assessment for expanded functions training at the start of a course. The other commenters expressed concern about the reduction in the clinical practice requirement prior to training in expanded functions. This concern arose from the elimination of the minimum training requirement prior to a dental assistance trainee becoming a registered dental assistant, as adopted in ARC 6673C (11/16/22 IAB). The concerns focused on potential risks to the public as a result of the services being performed before the dental assistants are fully prepared.

The following changes from the Notice have been made:

A revision to Chapter 10 to reflect an earlier change to Chapter 23 and Iowa Code section 153.38 in Item 1. Subsequent items have been renumbered;

Instead of rescission, an amendment is made to the definition of "provisional restorations" in new Item 3. Subsequent items have been renumbered;

A reorganization of the orthodontic functions to better meet the needs of orthodontic offices;

Updates to the minimum training standards based on input from members of the public and the reorganization of some of the Level 1 expanded functions; and

The grouping of the placement of temporary restorative materials into a single function as opposed to two separate functions.

Adoption of Rule Making

This rule making was adopted by the Board on November 21, 2022.

Fiscal Impact

This rule making has no fiscal impact to the State of Iowa.

Jobs Impact

After analysis and review of this rule making, there will be a positive impact on jobs in Iowa since the rule making allows licensees and registrants greater flexibility to grow within the profession.

Waivers

Any person who believes that the application of the discretionary provisions of this rule making would result in hardship or injustice to that person may petition the Board for a waiver of the discretionary provisions, if any, pursuant to rule 650—7.4(17A,147,153).

Review by Administrative Rules Review Committee

The Administrative Rules Review Committee, a bipartisan legislative committee which oversees rule making by executive branch agencies, may, on its own motion or on written request by any individual or group, review this rule making at its regular monthly meeting or at a special meeting. The Committee's meetings are open to the public, and interested persons may be heard as provided in Iowa Code section 17A.8(6).
