Expanded Function Dental Auxiliary (EFDA)

This continuing education program is hands-on and will take place in person.

Course Description

The College of Dental Medicine's EFDA CE program is designed for Dental Assistants, Dental Hygienists, and foreign trained dentists who would like to expand their role in patient care under the supervision of MWU College of Dental Medicine (CDMA) Faculty who are also Arizona licensed dentists. This extensive program is modular in design with a total of 106 hours of instruction that prepare participants for the Dental Assisting National Board (DANB) exams required to obtain the Arizona State Board approved EFDA certification. Included in the 106 hours are 72 hours of hands-on simulation instruction.

Equipment, including high and low speed handpieces, hands-on dental supplies and educational materials are included in the Course Fee.  Mock exams to prepare for the DANB examinations will be included as part of the curriculum.

All participants are loaned their own typodonts to take back to their dental offices for additional practice.  Hands-on modular sections will consist of 50+ exercises, including placement of amalgam, composites and stainless steel crowns. The participant to faculty ratio of 6:1 will emphasize individual attention and success.

Educational Expectations

The EFDA Program is a very rigorous and challenging course. Participants are expected to attend ALL lecture, laboratory and clinical sessions.

Participants will be taught by the same faculty instructors who teach the MWU College of Dental Medicine students during the week.   Faculty attention during hands-on exercises will be strengthened by a participant faculty ratio of one instructor for every six (6) participants.  It is important to the MWU faculty that participants comprehend and meet their goals.

Participants must be very familiar with restorative procedures, be able to use both direct vision and indirect mirror vision to complete and evaluate restorations, and will have to perfect fine motor skills to enable the accurate and safe application of dental hand pieces and instruments.

The EFDA Program utilizes digital learning support materials to supplement in-class learning (34 HOURS). Therefore, participants must have access to a computer to utilize the provided thumb-drive. Printed materials are not provided.

Instruction takes place at Midwestern University College of Dental Medicine's state-of-the-art student Simulation Clinic. Each participant will have their own workstation, handpieces, instruments, materials, typodont, adjustable overhead lamp, and life-like patient simulator to learn skills necessary in the restoration of teeth as described within this document. A typodont will be loaned to participants for additional practice.

It is the responsibility of the employer-dentist to allow the EFDA trainee to perform intra-oral procedures (restorations) in the office once the participant has successfully passed the amalgam, composite, and sealant competencies.


Program Performance Requirements

All participants admitted to the Expanded Function Dental Auxiliary (EFDA) Continuing Education Program must be able to meet all of the following requirements:

  • Participants must be familiar with restorative procedures.
  • Four-handed general dentistry experience is expected.
  • Participants must be able to use both direct vision and indirect mirror vision to complete and evaluate restorations, and will have to perfect fine motor skills to enable the accurate and safe application of dental hand pieces and instruments.
  • Participants must be familiar with basic dental terms and nomenclature.
  • Participants must be able to function effectively under the time constraints of the program and display flexibility in the event of changing lab and clinical situations.
  • Participants must be able to apply didactic learning (theory) to clinical situations.
  • Participants must be able to hear and communicate effectively, follow directions, and act professionally in class. 
  • Participants must be able to read the printed words in EFDA textbooks and supplemental information, observe various dental instrument angulations and apply the concepts appropriately.
  • Participants' eyesight must be able to visualize fine detail (either naturally or corrected), have depth perception, and have the ability to visualize three-dimensional objects.
  • For everyone's safety, each participant must be physically free of the use of non-prescription drugs, illegal drugs, and alcohol.

An EFDA must have use of both hands, dexterity in the fingers, and tactile sensitivity to manipulate dental instruments, materials, dental hand pieces, and operate dental equipment as well as the ability to manipulate the floor rheostat for hand piece operation, and other adjunct dental equipment. The participant must be able to work from a dental operator stool in order to perform dental procedures. The ability to sit and stand for a duration of time is also necessary.  

Other specific requirements include color discrimination (differentiation of various shades of color and gradations from black to white); manual dexterity/motor coordination (discern changes in surface textures by manipulating dental instruments, control exertion of hand/finger pressure); hand-eye coordination (transfer of visual input into motor output); physical communications (hear commands through operator's face mask); visual acuity (identify the working ends of various dental instruments and implements at a two foot distance); form/spatial ability (view in three-dimensional relationships, distinguish subtle changes from one form or shape to another, discriminate intricate measurements); and language development.
