Learning Objectives:

Upon completion of this course, participants should be able to do the following:

  1. Describe the evidence for the etiology of periodontitis.
  2. Explain the limitations with the current plaque paradigm.
  3. Describe the genetic susceptibility scientific breakthrough.
  4. Identify how the genetic information changes and improves the ability to allocate resources and improve treatment.


Abstract:
The discovery of a genetic marker that is highly associated with increased risk for severe periodontitis is a major breakthrough in the clinical management of all dental patients. The marker is not diagnostic; rather, it is a prognostic test and it is used to identify patients who are much more susceptible to plaque. Individuals who have the marker have a 6 to 19 times higher chance of getting severe periodontitis than those who do not have the marker. It is estimated that 30% of the US population will test positive. This new information supplements existing microbiology and immunology research. A limitation of the established view of the etiology of periodontal disease makes it difficult to explain why certain patients are more or less at risk based solely on their level of oral hygiene. It has also been difficult to predict the clinical outcomes of various treatments for individual patients because each person implements their own oral hygiene differently. The genetic discovery helps to explain why some people with a little plaque have a lot of disease, and why other people with a lot of plaque have only minor problems. By incorporating the constant factor of genetics into your philosophy of practice, the patient's periodontal needs and desires can be better understood and managed.
