Expanded Functions Dental Assistant Training Course

The Expanded Functions Dental Assistant (EFDA) course is designed to prepare students to meet the Arizona State Board of Dentistry’s requirements to apply for the Arizona Expanded Functions – Restorative Certificate. The course is a blend of academic and clinical laboratory competency with an emphasis on anatomy, restorative and temporization procedures. This course prepares students to take the DANB® examinations and to work in conjunction with a supervising dentist to complete clinical competencies for certification.

This course is a noncredit course open to dental assistants and licensed dental hygienists in Arizona. Students will complete lessons through Rio Salado College’s learning management system called RioLearn. The academic portion of the course will be approximately 10 weeks. The coursework is self-paced. Students will be required to attend 3 in-person labs which will be held on 3 consecutive Saturdays, 8am-5pm.

Lab sessions will be held at the Rio Salado Dental Clinic at 2250 W. 14th St., Tempe, AZ 85281. These labs will assist the student in developing lab competency to meet the State Board of Dentistry’s requirements for the EFDA. Students will perform expanded function restorative procedures including amalgam, composites, indirect temporary restoration, stainless steel crown, occlusion considerations, infection control, and caries prevention in a clinical lab environment.
