OPA EFDA Pilot Project


The MDA is the original provider of  Expanded Function Dental Assistant (EFDA) education in the state. As long-time stewards of this program, we are using our knowledge and expertise to develop a pilot project (along with the State Office of Dental Health and the Missouri Dental Board) to show the effectiveness and safety of creating an Oral Preventive Assistant (OPA) — a new type of EFDA — who could provide supragingival scaling patients diagnosed as periodontally healthy or with gingivitis. The Fall 2023 edition of the Focus magazine gives specifics on this project and outlines many other efforts to address oral healthcare workforce shortages and the Spring 2024 edition provides a brief update on where we are with the OPA EFDA. The Fall 2024 edition provides another updated related to the rule promulgation.

Three helpful resources that have been published include:

This webpage provides extensive information on workforce issues and the development of the OPA Pilot, and recent activity on the pilot includes:

  • July 2023 – Waiver of Rules approved by Missouri Dental Board for OPA EFDA Pilot
  • October 2023 – Approval of OPA Curriculum by Missouri Dental Board for OPA EFDA Training
  • October 2023 – OPA RFA Site Application & Selection Process Began
  • November 2023 – OPA Clinical Site Training for Dentists and Dental Teams
  • January through March 2024 – OPA Didactic & Hands-On Trainings Held 
  • May 1, 2024 – Rule changes officially published in the Missouri Register for comment period, after which it went to the Joint Committee on Administrative Rules (JCAR) see excerpted Dental Board Rule Changes from Volume 49, Number 9
  • September 1, 2024 – Register with rule changes filed by JCAR
  • October 1, 2024 – Final order of rulemaking published (code publication date will be October 31, with code effective date November 30) Volume 49, Number 19
  • December 1, 2024 – OPA EFDA Pilot Project to officially commence in pilot clinical sites, with expanded functions being performed and data gathered, limited to the design and scope of the pilot project

Pilot Project Overview

About the Project

This Missouri Office of Dental Health (ODH) asked the Missouri Dental Board (MDB) at it's April 2023 meeting to support a pilot project to address the urgent workforce challenges and provide increased access to care.

The project will examine the use of an Oral Preventive Assistant (OPA) Expanded Function Dental Assistant (EFDA) (herein referred to as OPA) to deliver preventive care, including supragingival scaling on healthy patients. This document is intended to outline the reasons and supportive details for this consideration.

The shortage of dental health care workers, specifically the shortage of RDHs, is significant. The ODH has been examining this issue for more than two years and feels global decisions to increase care for the underserved, especially in rural populations, needs to be addressed immediately. Creating an OPA position would build on the proven approach of allowing dental assistants to, under supervision, assist with restorative, orthodontic and fixed prosthetic and removable prosthetic care. It would be conducted and measured within the statute allowing pilot projects to exist.

The results of the pilot project will be reported to all major stakeholders, including the Missouri Dental Board and the Missouri Department of Health and Senior Services through the Office of Dental Health.

Statute allowing Pilot Project

RSMo 332.325 allows for pilot projects to apply new methods of care delivery within small, scaled projects to address the needs of the underserved. Within the language, seven core competencies must be met to allow for examination of the project, including specific timelines and reporting. Read for a further explanation:  An Overview of the Oral Preventive Assistant (OPA) Pilot Project

What would the OPA EFDA do?

  • Dental assistants who complete the OPA curriculum and pass the written OPA qualifying exam, will then be eligible in the pilot program assist dentists and hygienists with:
    • Scaling supragingival calculus
    • Polishing teeth; and
    • Giving oral hygiene instructions.
  • OPAs would work under direct supervision of a dentist or hygienist.
  • OPAs would treat patients who are healthy or who have reversible gum inflammation, not patients with advanced gum infections.

Why is an OPA EFDA position necessary?

  • With Missouri’s significant shortage in dental healthcare workers, specifically hygienists and assistants, new approaches to deliver care are at a critical status, especially in rural areas.
  • Having an OPA gives dentists another tool to manage their practice and deliver care efficiently.
  • With the assistance of OPAs, dental hygienists and dentists will have more time to complete the complex procedures they have trained for.
  • We need to provide an immediate solution to workforce challenges that utilizes the workforce we already have while we work to expand the RDH and DDS workforce.
    • ODH supports several workforce solutions, including increasing the number of schools and class sizes for hygienists in Missouri, but these solutions will take time.
    • Expanding the scope of current team members is a more immediate and less costly solution.

Will this be safe for patients?

  • Safety and patient care are our top priorities. That is why we are proposing that dental assistants complete an OPA didactic curriculum, pass a qualifying examination, and work under the supervision of a dentist or hygienist.
  • The OPA will be supervised, and the patient checked before dismissal.
    • Allowing a trained assistant to scale will still be at the doctor’s discretion. As with other expanded functions, if the doctor is not comfortable delegating this, they do not have to allow it in their practice.
  • Like any care provider, OPAs will require appropriate training for their scope of practice. We believe assistants can be trained to scale above the gum line safely, and this is what the pilot program will assess.
  • We are proposing that dental assistants be trained to remove hard build up above the gum line on healthy teeth. The potential risks are far fewer than other tasks that assistants already perform. 
    • Under current law, assistants with proper training can trim fillings below the gum line with a high-speed handpiece or scalpel blade.
    • Assistants currently can utilize other sharp tools including scalpel blades, metal reduction discs and high-speed handpieces with burs.

Is there precedent for this type of Expanded Function?

  • While OPAs would be new in Missouri, this is not a reinvention of the wheel. Other states and the U.S. military already allow assistants to practice scaling.
  • Two neighboring states, Illinois and Kansas, have already implemented this change effectively.
    • There have been no reported incidents with assistants practicing scaling in these
      states.
    • The project is so successful, Kansas does not even track these very safe procedures.
    • As of last year, assistants in Illinois can work on children who are on Medicaid or are uninsured.
  • The U.S. military has also allowed assistants to practice scaling for years.

What are the next steps with the OPA EFDA Pilot Project?

  • With the Missouri Dental Board support, ODH will seek to carry out the pilot program. The pilot project will:
    • Develop an appropriate curriculum for the scope of an OPA.
    • Identify sites to test the use of an OPA.
    • Educate eligible clinical staff using the OPA curriculum.
    • Establish clinical and testing protocols.
    • Ensure competency of clinical staff.
    • Collect data on clinical outcomes including the number of more advanced cases treated by hygienists and dentists. 
  • Now with approval of the MDB, the MDA will undertake the OPA-EFDA pilot program, with ODH supervision.
