Course lectures for this introductory study of the concepts and techniques of delivering intraoral anesthesia are provided online and coordinated with clinical practice. Emphasis is on the prediction and prevention of medical complications. Curriculum includes head and neck anatomy, armamentarium, pharmacology, neurophysiology, patient evaluation and management, record keeping and risk management.

The goal is to safely select and administer adequate local anesthesia for use in painless periodontal treatment. Course consists of 24 lecture hours and 24 clinical hours in which students practice injection techniques under the supervision of a NH-licensed dentist and qualified dental hygienist. Upon successful completion of the course, the ADEX exam, and obtaining a NH permit, hygienists will be qualified to administer local anesthesia according to NH law.

This is a hybrid course with self-paced online modules. The modules can be completed early on or spread out during the time remaining from the date of registration. The clinical portion would be scheduled with the instructor to join an on campus lab currently in progress with the Dental Hygiene students.

Dental Hygiene Refresher Fact Sheet

This hybrid course was prepared for dental hygienists who have been out of practice for a time and want to get back into the field or for those who are practicing, but feel their skills need updating. Individuals interested in taking the refresher course are required to have an inactive or current Dental Hygiene License. 

The course is designed to review theory and techniques learned in dental hygiene school and on the job. Current “best practices” will be introduced, but specialized procedures will not be covered in great detail and, in some cases, will require additional courses.

Program Goals:

• Dental Hygiene Process of Care
• Definitive Oral Prophylaxis
• Radiographic Techniques
• Review of Current Center for Disease Control (CDC) Guidelines
• Review of Hand Instrumentation including Ultrasonics

Course objectives are met through didactic and clinical instruction which will introduce, update, and review current techniques in the practice of dental hygiene.

Program Outcomes: 

Participants who complete the course can be assured they have had the opportunity to learn the most up to date, science-based theory and techniques.

If you’ve ever taken an x-ray only to realize the apices or incisal edges are cut off, or the contacts are overlapped or have difficulty managing a gag reflex and the image needs to be retaken—you’re not alone. When these errors happen again and again, it often means small technique adjustments are needed—and this course will show you exactly how to confidently correct them and achieve consistent, diagnostic results.

Common radiographic errors can be frustrating, time-consuming, increase radiation exposure and disruptive to patient care. This course is designed to help you identify exactly why these errors occur and give you simple, effective techniques to correct them and correct them with confidence, as well as provide strategies for managing a gag reflex to improve patient comfort and imaging success.

This hands-on, personalized refresher course is designed for licensed dental hygienists and DANB-certified dental assistants seeking to strengthen digital radiography skills and build confidence in producing diagnostic-quality images. Tailored to each participant’s specific challenges, participants practice with digital sensors on manikins and receive real-time coaching. Instruction covers adapting techniques for anatomical variations—such as narrow or shallow palates and large tori—and managing gag reflex to improve patient comfort and imaging success.

Upon completion, participants will demonstrate improved confidence, efficiency, and accuracy in producing diagnostic radiographs in a clinical setting.

CEU: 2

Note: CEU’s are not issued if a participant does not pass the class.

Grade Mode:  Pass or Fail

Learning Objectives:

Upon successful completion of this course, participants will be able to:

1. Produce diagnostic-quality radiographs using proper receptor placement angulation, and beam alignment techniques in accordance with accepted clinical standards.

2. Identify common radiographic errors and apply corrective techniques to minimize errors and reduce the need for retakes, supporting radiation safety principles.

3. Demonstrate proper digital sensor placement and stabilization for accurate and consistent image capture.

4. Adapt radiographic techniques and tips for anatomical variations, including narrow palates, tori, shallow palate or floor of the mouth.

5. Utilize effective strategies and techniques for managing gag reflex to improve patient comfort and procedural success.

6. Improve clinical efficiency while maintaining compliance with radiation safety standards and best practices.

7. Demonstrate increased confidence and competence in performing digital radiographic procedures.
