Dental - Expanded Functions Dental Auxiliary Program (EFDA)

The EFDA program meets the requirements established by the Pennsylvania State Board of Dentistry and prepares students to take the written EFDA Examination that has been approved by the State Board of Dentistry. Students will achieve basic competence for placing and finishing both amalgam and composite resin restorations on patients. Upon completion of the program, students will be eligible for the EFDA examination and may apply to the State Board of Dentistry for certification.

To qualify for the program, students must have
current Pennsylvania licensure as a dental hygienist OR current DANB certification as a dental assistant (Required by the program, not by the state).

The program consists of two courses and begins Fall  semester.  The first is a 4 credit course (DA 252), 15 weeks, Monday and Tuesday evenings from 6:30 – 9:30 pm.  This course is offered at the Harrisburg campus only during the fall semester. This course is a lecture and lab session.

The second part of the program (Spring semester) requires clinical hours in the EFDA clinics as well as in the assistant's (student's) dental practice.  This is a 1 credit course (DA 253) requiring 15 weeks of approximately 8 hours of clinical externship per week.  Monday and Wednesday evenings are required EFDA clinics from 6 – 9 pm.  This course concludes when the documented hours are completed (can take longer than one semester).  Students are required to complete a portfolio including photos of their work.

Current estimated expenses including tuition and course fees for DA 252 and DA 253. 

Enrollment is limited to 15 students for the complete program.
