Changing Concepts of Ultrasonics

The science behind ultrasonic debridement is changing rapidly!  New research shows that Canadian Dental Hygienists are underutilizing and incorrectly implementing ultrasonics.  Don’t be part of this demographic. Today, ultrasonic instrumentation goes far beyond the removal of calculus. Effective removal of biofilm is critical in the fight against inflammation and ultrasonics used as part of modern debridement strategies can be both a valuable and comfortable choice.  Gain the necessary scientific and practical information to enhance your knowledge when choosing the right insert, power level and adaptation to reach clinical end point.


  • Describe the benefits of ultrasonic technology as they apply to the removal of calculus and BIOFILM.
  • Discuss the relationship of biofilm removal in periodontal therapy to inflammation reduction and achieving overall health.
  • Discuss the benefit of ultrasonic therapy over hand instrumentation.
  • Understand how ultrasonic technology relates to effectiveness, efficiency, patient comfort and clinician health.
  • Select the appropriate inserts, power level and adaptation technique for calculus/biofilm removal.

Challenge the Polishing ‘Routine’

Selective polishing philosophy is creating controversy nationwide as it challenges clinicians to assess the value and method of coronal polishing for each patient.  With essential selective polishing replacing traditional selective polishing, the presentation will take an up- close and personal look at this philosophy.   Participants will examine rubber cup and air polishing, gaining insight into the most up-to-date equipment, clinical technique and therapeutic agents.  Positive and adverse affects on teeth, soft tissue and restorations will be discussed.   Go beyond stain removal and fluoride.  Routine – I think Not!


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

  • State the principles of selective polish
  • Compare current polishing methods: rubber cup versus airpolishing giving consideration to natural tooth and man-made restorative structures
  • Compare safety and efficacy of current polishing pastes and agents
  • Recognize the ergonomic benefits of current polishing armamentarium
  • List a variety of coronal polishing ‘technique pearls’ which help to increase speed, decrease mess and preserve tooth structure


Cheri Wu opened ‘Focus on Dental Hygiene’ an independent dental hygiene clinic in Victoria, British Columbia in 2011, where she continues to practice. A graduate of the University of British Columbia with a Bachelor of Dental Science Degree she was also presented with the Gold Medal for Academic Excellence. Cheri holds a Faculty position with Camosun College Dental Hygiene program and teaches to dental hygiene students, she also continues to instruct to Dental Hygienists and Dental Hygiene Students on a variety of scientific, evidence based ultrasonic instrumentation and air polishing techniques. In 2012 Cheri received the Camosun College Distinguished Alumni Award and in 2014 she received the Barbara Heisterman Award for Innovation and Commitment to Care.
