O-5 Predictors of Endodontic Outcomes: A Summary of Practice

Product not yet rated

CE Credits: 1.5

Course Description:  A number of studies have addressed outcomes of nonsurgical root canal treatment. However, there are relatively few prospective large-scale studies that have assessed the frequency of post-operative pain and tooth survival. This interactive presentation will summarize findings from previous research on short- and long-term outcomes of nonsurgical root canal treatment with an emphasis on findings from recent practice-based research results. In addition, participants will be given opportunities to provide input as to which patient-, tooth- and treatment-level factors should be evaluated as predictors of these endodontic outcomes.  

At the conclusion, participants should be able to:

  • Summarize practice-based research findings related to short- and long-term outcomes following nonsurgical root canal treatment.
  • Identify patient-, tooth- and treatment-level factors that might influence endodontic outcomes.
  • Discuss how endodontists can participate in practice-based research to help determine the factors that predict endodontic outcomes.

Dr. Alan S. Law received his doctor of dental surgery and Certificate in Endodontics from the University of Iowa College of Dentistry, Iowa City, Iowa. He also completed his Ph.D., “Mechanisms and Modulation of Orofacial Pain,” with the department of pharmacology at the University of Iowa. Dr. Law has published several of articles in scientific and clinical journals, and has co-authored chapters on "The Non-Odontogenic Toothache" and "Regenerative Endodontics in Pathways of the Pulp. " He teaches continuing education courses at the University of Minnesota, is a past president of the Minnesota Association of Endodontists and a former director of the American Association of Endodontics. He is a past president of the American Board of Endodontics. He is in full–time practice in the Twin Cities with The Dental Specialists, a multi-specialty dental practice, and an adjunct associate professor in the division of endodontics at the University of Minnesota.

Donald R. Nixdorf, D.D.S., M.S.

Dr. Donald Nixdorf graduated from the University of Alberta Faculty of Dentistry in 1996. He completed a hospital dentistry residenty and masters at The Ohio State University, anesthesia fellowship at Johns Hopkins University, orofacial pain fellowship at the University of Alberta, an internship within the summer institute in clinical dental research at the University of Washington, and was a visiting research fellow at the University of Oxford with FMRIB. Most recently he completed a master of science in clinic research in the University of Minnesota School of Public Health as a part of his K12 training program. Dr. Nixdorf is an associate professor, division director, and past graduate program director at the University of Minnesota in the division of TMD & orofacial pain. He is an adjunct assistant professor in the department of neurology, research investigator in the HealthPartners Institute for Education and Research, and the deputy director of the Midwest Region within the National Dental Practice-Based Research Network. Dr. Nixdorf is a Diplomate of the National Dental Board of Anesthesiology (NDBA) and the American Board of Orofacial Pain (ABOP). Dr. Nixdorf's research is focused on the topic of persistent non-odontogenic “tooth” pain, exploring issues related to classification, diagnosis, epidemiology, exploration of mechanisms, and treatment options. As well, he is involved in the development of dental MRI as technology to assist in the determination of when local disease is presence or absent. Dr. Nixdorf also maintains a clinical practice restricted to the diagnoses and management of chronic TMD pain, headaches, and neuropathic pain. He sees patients at the University of Minesota School of Dentistry, as well as within the M-Heath hospital system.
