From early in recorded history, evidence attests to a human zeal to scrape off accretions on the teeth. Contemporary hand instruments for removing obvious deposits developed from their primitive precursors and eventually became the so-called gold standard for debridement. Indeed, the basic design of these instruments has changed only minimally over the centuries. More recently, however, a better understanding has emerged of the bacteria that initiate periodontal destruction. They take the form of a biofilm that often cannot be seen or felt with traditional hand instruments. To disrupt this biofilm and resolve periodontal inflammation, ultrasonic instrumentation arguably presents the most effective tool available to clinicians. This article reviews the insights into the etiology of periodontal disease and discusses the proper use of ultrasonic instrumentation.


  • Define biofilm and explain its etiology.

  • Discuss the role of inflammation in the relationship between oral and overall health.

  • Describe how to best interrupt the biofilm that triggers periodontal disease.

  • Explain the theory behind the new goal of debridement.
