Please read this section carefully! If you are waitlisted for this course, you are encouraged to register for another course in addition to this one.

The periodontal EFDA course is designed to teach dental assistants to provide dental cleanings to remove visible calculus by using state-of-the art Piezoelectric scalers or Magnetostrictive ultrasonic scalers. Hand scaling is no longer a part of the periodontal EFDA curriculum.

Pre-Course Requirements:

1. All DAs registered in this course must complete the prerequisite course, DA0001, at least 2 weeks prior to the start of the course. Failure to do so may result in removal from the course by the course director.
2. All DAs registered in this course should be prepared to take the course. If you feel that you need additional preparation prior to the course, please work with your dental director.
3. All DAs and course instructors participating in this course must comply fully with IHS COVID-19 vaccination requirements. Failure to comply will result in removal from the course by the course director.

During the Course:
1. Participants are expected to pass a series of didactic [lecture] and clinical examinations to show proficiency in course content. This includes clinical work with typodonts and with real patients.
2. At the conclusion of the weeklong course, the course director will provide participants with a completion code. The DA will then have 3 days to complete the online post-course evaluation and get CDE credit. Failure to get CDE credit will result in non-certification down the road, so it is important to do this right away!

Post-Course Requirements:
1. DAs must complete 20 dental cleanings which are checked and scored by the hygienist/dentist at their home dental clinic. These should be done under direct supervision of the dentist or hygienist [dentist/hygienist in the room while the DA is performing the cleaning, able to provide tips and recommendations as needed]. Grading is documented on the Follow-Up Training Progress Record provided by the course director, which is then maintained at the local program.
2. Post-course requirements must be completed within 6 months of the EFDA training.
3. When the DA has satisfactorily completed the post-course cleanings, the dental chief/director under whose license the DA will be working should then e-mail the IHS EFDA Coordinator [] to inform them that post-course requirements have been met and that the record is on file at the local clinic. This should be done using this format only: "_______________________ [name of DA] has satisfactorily completed the post-course requirements as a periodontal EFDA. He/she took course ____ [course number] on ______ [date] at ______________ [location]. A copy of his/her evaluation form is being maintained in this office. Please issue instructions for certification.”
4. Once this is done, the IHS EFDA Coordinator will provide the student with instructions on how to receive their CDE certificate and their EFDA certificate.
5. After the 20 cleanings done under direct supervision by the dentist/hygienist, the DA should NOT perform any further cleanings unless CERTIFIED by the IHS EFDA Coordinator. Following certification, the new EFDA may perform cleanings under indirect supervision [dentist/hygienist in the facility but not directly overseeing the work until a final check is needed].

Annual Competency:
1. The Dental Director/Dental Chief is encouraged to complete an annual competency evaluation on the periodontal EFDA to ensure high quality care is being delivered.
2. The annual competency evaluation can be found on the IHS Dental Portal under the Clinic Tab - Competencies.

Learning Objectives:

Upon completion of this course, participants will be able to:
1. Relate Community Periodontal Index of Treatment Needs [CPITN] scores to a need for potential periodontal treatment.
2. Detect disease, supra and subgingival calculus.
3. Provide thorough ultrasonic scaling of teeth..
4. Accurately code for periodontal and hygiene procedures with IHS/ADA coding. .
5. Recommend effective toothpastes, mouth rinses and oral hygiene aids to patients.
6. Motivate patients to improve plaque removal and periodontal health.
7. Identify who is at risk for periodontal breakdown.
