DENTAL BOARD[650]

Notice of Intended Action

Proposing rule making related to expanded functions for dental assistants and dental hygienists and providing an opportunity for public comment

The Dental Board hereby proposes to amend Chapter 10, "General Requirements," Chapter 15, "Fees," and Chapter 20, "Dental Assistants," to adopt a new Chapter 23, "Expanded Functions," and to amend Chapter 25, "Continuing Education," Iowa Administrative Code.

Legal Authority for Rule Making

This rule making is proposed under the authority provided in Iowa Code sections 147.76, 153.33 and 272C.3.

State or Federal Law Implemented

This rule making implements, in whole or in part, Iowa Code sections 153.15, 153.38 and 153.39.

Purpose and Summary

The primary purpose of these proposed amendments is to update the requirements for expanded functions. The proposed amendments move some procedures into the standard scope of practice for dental assistants and dental hygienists, and also allow additional procedures to be performed by dental assistants and dental hygienists as new expanded functions. The amendments also include updated terminology to make the rules clearer.

These proposed amendments create a new Chapter 23 for all expanded function requirements. The proposed amendments remove the expanded function requirements currently established in Chapters 10 and 20 and relocate the content into proposed Chapter 23. The intent is to make it easier for dental hygienists and dental assistants to locate the requirements for expanded functions by placing all of the requirements in a single chapter.

These proposed amendments establish clearer requirements for training in expanded functions to ensure that a minimum standard of competency is met at the completion of all expanded function training courses. A review of expanded function training courses to date has shown that there is not a clear minimum training standard. These amendments would resolve this concern.

These proposed amendments also create a process whereby expanded function dental assistants and dental hygienists may obtain a certification from the Dental Board recognizing the ability of those dental assistants or dental hygienists to perform Level 1 and Level 2 expanded functions. A certification process has been requested by dentists who have delegated these services and by dental hygienists and dental assistants who have performed expanded function procedures. Certification as an expanded function dental assistant or dental hygienist would be required only for those who wish to complete training in Level 2 expanded functions. The certification would be optional for those who complete training in all Level 1 expanded functions and who opt not to train in Level 2 expanded functions.

These proposed amendments also establish fees related to the certification of expanded function licensees and registrants, for a hard copy of a duplicate certificate or proof of renewal, and for educational services provided by the Board.

Fiscal Impact

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

Jobs Impact

After analysis and review of this rule making, no impact on jobs has been found.

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 650—Chapter 7.

Public Comment

Any interested person may submit written or oral comments concerning this proposed rule making. Written or oral comments in response to this rule making must be received by the Board no later than 4:30 p.m.on July 1, 2019. Comments should be directed to:

CHAPTER 23

EXPANDED FUNCTIONS

650—23.1(153) Definitions. As used in this chapter:

"Accredited school" means a dental, dental hygiene, or dental assisting education program accredited by the Commission on Dental Accreditation (CODA).

"Clinical training" means training which includes patient experiences.

"Didactic training" means educational instruction.

"Direct supervision" means that the dentist is present in the treatment facility, but it is not required that the dentist be physically present in the treatment room.

"Fabrication" means the construction or creation of an impression, occlusal registration or provisional restoration, as defined in this chapter.

"General supervision of a dental assistant" means that a dentist has examined the patient and has delegated the services to be provided by a registered dental assistant, which are limited to all extraoral duties, dental radiography, intraoral suctioning, use of a curing light, intraoral camera, and recementation of a provisional restoration. The dentist need not be present in the facility while these services are being provided.

"General supervision of a dental hygienist" means that a dentist has examined the patient and has prescribed authorized services to be provided by a dental hygienist. The dentist need not be present in the facility while these services are being provided. If a dentist will not be present, the following requirements shall be met:

1.Patients or their legal guardians must be informed prior to the appointment that no dentist will be present and therefore no examination will be conducted at that appointment.

2.The hygienist must consent to the arrangement.

3.Basic emergency procedures must be established and in place, and the hygienist must be capable of implementing these procedures.

4.The treatment to be provided must be prior prescribed by a licensed dentist and must be entered in writing in the patient record.

"Intermediate restorative material" means any restorative material intended to remain in place for up to one year.

"Laboratory training" means training that is hands-on, that may include simulation, and that prepares a dental hygienist or dental assistant for patient experiences. Laboratory training can be done as part of an approved course, or obtained through a supervising dentist.

"Observational supervision," for expanded functions, means the dentist is physically present in the treatment room to oversee and direct all services being provided as part of clinical training.

"Patient experiences" are procedures that are performed on a patient, during the course of clinical training, under the observational supervision of a dentist.

"Prosthetic" means any provisional or permanent restoration intended to replace a tooth or teeth.

"Provisional restoration" means a crown or bridge placed with the intention that the crown or bridge will be replaced with a permanent crown or bridge at a later date.

These exceptions may be performed under general supervision. Dental assistant trainees are not eligible to perform or receive training in expanded function procedures.

23.2(2) A dental hygienist or dental assistant shall not perform any expanded function procedures listed in this chapter unless the education and training requirements have been met and certification has been issued to the dental hygienist or dental assistant.
