EFDA Programs at NHTI

EFDA Program Overview

The NHTI EFDA program is designed to prepare CDAs, RDHs, and graduates of a CODA-accredited school of dental assisting to function efficiently and safely as an integral member of the dental team.

EFDA, already used in 30 states, provides assistance and additional efficiencies at dental practices and public health clinics. According to the N.H. Board of Dental Examiners, to be qualified to place, contour, and adjust direct restorative materials within the oral cavity, you must:

  • Meet the program pre-requisites as outlined on this web page.
  • Successfully complete a board-approved EFDA course.
  • Register as an EFDA with the N.H. Board of Dental Examiners.
  • Work under direct supervision of a N.H.-licensed dentist.
  • Complete required continuing education coursework biennially.

The successful EFDA participant:

  • Has a positive attitude and is eager to learn
  • Enjoys new challenges and responsibilities
  • Values upward mobility in dental career
  • Is committed to the profession and continuing education
  • Communicates well with patients and the dental team
  • Handles stress well and is neat and organized

  • 50 hours of didactic (classroom-based) instruction
  • 100 hours of pre-clinical instruction (working on typodonts in the clinic)
  • 6 weeks, minimum of 120 hours, of clinical experience in dental office with sponsoring dentist

The sponsoring dentist must agree to support the EFDA trainee in performing intra-oral procedures (restorations) in the office once the student has successfully completed classroom and pre-clinical instruction.

After completion of the didactic and pre-clinical instruction, participants begin the 6-week, minimum 120 hours, of satellite clinical experience in their sponsoring dentist/office. The specific requirements, competencies, and clinical training will be overseen by the participant’s sponsoring dentist with support from the NHTI EFDA faculty.

EFDA participants will have four months to complete the requirements, which, with a passing grade, will allow them to register with the NHBODE and obtain an EFDA permit from the board. After successful completion of the 270-hour program, the EFDA dental hygienist or dental assistant shall be considered qualified to place, contour. and adjust direct restorative materials within the oral cavity.
