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

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. The program satisfies the criteria of the NH Board of Dental Examiners when a refresher course is mandated for hygienists who want to renew their active dental hygiene license. 

CEUs: 20

Program Description:

• Online Assessment and Review of Theory (2 CEUs)
  • Must be completed prior to attending clinical portion.

  • 4-hour clinic session
  • 2-hour radiology review

The online portion needs to be completed before the start of the scheduled hands-on sessions. 

The scheduling of this course will be based upon faculty availability. Students are expected to provide one client for the clinical portion of the course.
