CE Hours: 1.0

Course Description:

This presentation will address the mechanical behavior of dentin, with special emphasis on the strength and fracture resistance. Details regarding spatial variations in the mechanical behavior within the root and crown will be described, as well as the changes that occur as a result of physiological aging. The mechanisms responsible for the changes in mechanical behavior will be discussed, as well as the potential contribution of these changes to the incidence of tooth fracture.

At the conclusion, participants should be able to:

  • Apply principles of evidence based medicine in rationale for a clinical intervention. 
  • Explain the consequences of treating or not treating an existing apical pathology. 
  • Describe the potential of modern endodontic treatment for the management of endodontic complications and how these strategies should be implemented in clinical decision making.

Dwayne D. Arola, Ph.D.

Dwayne Arola is currently a professor of Material Science and Engineering (MSE) at the University of Washington. He holds joint appointments in the departments of Oral Health Science, Restorative Dentistry and Mechanical Engineering. Prior to his appointments at Washington he was a faculty member within the University of Maryland system. His research broadly involves studies concerning the microstructure and mechanical properties of dental, engineering and natural materials. His interests in the area of dental materials are focused on characterizing the durability of bonded interfaces to dentin and enamel, as well as understanding the importance of aging to the mechanisms of degradation and the practice of restorative dentistry.
