Shimon Friedman, D.M.D.
Dr. Friedman currently serves as Professor at the University of Toronto Faculty of Dentistry. He had served for 20 years as the Head of Endodontics and for 22 years as the Director of the M.Sc. Endodontics Program.
He received his D.M.D. degree and endodontics certificate from the Hebrew University and Hadassah Faculty of Dental Medicine in Jerusalem, Israel, in 1975 and 1983, respectively. He had taught at Hebrew University for 16 years, spent one year as visiting professor at Temple University School of Dentistry in Philadelphia, PA, and has taught at the University of Toronto since 1992. In 1983, he was one of the first two endodontists to pass the specialty examination administered by the Scientific Council of the Israel Dental Association. He had served as a Scientific Council examiner (1983-1992) and as Chairman of the Israel Endodontic Society (1985-1988).
Dr. Friedman has published over 145 articles in peer-reviewed scientific journals, 11 textbook chapters and many research abstracts. He has presented over 300 lectures worldwide and had served on the editorial boards of major endodontic journals. Dr. Friedman has won several prestigious awards, among them the 2008 AAE Louis I. Grossman Award for his significant research and contributions to endodontology, the 2013 W.W. Wood Award of the Association of Canadian Faculties of Dentistry for excellence in dental education, the 2014 Award of Distinction of the Faculty of Dentistry, University of Toronto for outstanding leadership, and the 2018 AAE IB Bender Lifetime Educator Award for excellence in full-time educational pursuits.

Contracted Endodontic Cavities for Extended Tooth Survival – is Less More?
Topic: Nonsurgical Endodontic Treatment & RetreatmentLearning Objectives:
• Explain the rationale for contracted endodontic cavity designs
• Describe how contracted endodontic cavity designs differ from traditional designs
• Discuss the current refereed literature on the biomechanical and instrumentation efficacy impacts of contracted endodontic cavity designs
Although survival rates after endodontic treatment are high, occurrence of tooth/root fractures is a concern, attributed to tooth structure removal associated with endodontic cavity preparation. Novel contracted endodontic cavity (CEC) designs discard traditional principles of outline and convenience form and emphasize directed dentin conservation, in line with the contemporary concept of minimally invasive dentistry. While the proposed benefit of CEC may be increased fracture resistance of teeth potentially extending long-term survival, its potential risk is compromised canal disinfection, potentially impairing periapical healing. This lecture will outline recent research that suggests different biomechanical and instrumentation efficacy impacts of CEC in specific tooth types. The potential benefits and risks associated with CEC will be debated. Levels of evidence: The lecture content is primarily supported by in-vitro research data but makes reference to survival outcome studies.
One half-day lecture.
Outcomes and Outcome Predictors in Apical Microsurgery
Topic: Endodontic SurgeryLearning Objectives:
• Describe the methodological pitfalls in clinical outcome studies on apical microsurgery.
• Identify the current best evidence for long-term outcomes of apical microsurgery.
• Summarize the long-term outcomes and outcome predictors in apical microsurgery.
The prognosis of apical microsurgery has for a long time been disputed because of methodological considerations that may bias reported outcomes. This lecture will define the goals of apical microsurgery and related outcome criteria, outline key considerations in appraisal of outcome studies, establish the current best evidence, and highlight the expected long-term outcomes and their predictors, in regards to healing and asymptomatic function of the surgically-treated teeth. Levels of evidence: The lecture content includes systematic reviews, randomized controlled trials and prospective cohort studies.
One half-day lecture.
Retreatment, in the Era of Implants?!
Topic: Endodontics vs Single-Tooth ImplantsLearning Objectives:
•Define key concepts for supporting the practice of retreatment in an environment biased towards extraction and replacement of teeth with post-treatment apical periodontitis.
• Describe current strategies for case selection for retreatment or tooth extraction and replacement.
• Outline the least invasive retreatment techniques that can be used to preserve tooth structure and restorations.
Should we, and shall we still perform retreatments when dentists increasingly favor replacing root-filled teeth with implants? This lecture will highlight three key concepts addressing this pertinent question. First, case selection strategies must be revised recognizing implants as a viable alternative to retreatment. Second, emphasis on tooth structure conservation during retreatment is needed to maximize tooth longevity after treatment. Third, the technical possibilites and favorable prognosis of treatment should be emphatically communicated to the dental community and patients. Levels of evidence: the lecture content includes mainly prospective cohort studies.
One half- or full-day lecture.
Endodontic Treatment Outcomes – The Current Best Evidence
Topic: Outcome Assessment Success & FailureLearning Objectives:
Describe the methodological considerations for clinical research on prognosis.
• Identify the current best evidence for different endodontic treatment modalities.
• Summarize the outcomes and outcome predictors for endodontic treatment modalities.
The outcomes of endodontic treatment modalities have been debated in light of inconsistent reports on prognosis, confusing dentists and endodontists and potentially leading to skewed treatment decisions. To avoid confusion, treatment outcomes must be defined in relation to established goals and supported by the current best evidence. This lecture will define the specific outcome goals of endodontic therapy, outline criteria for appraisal of studies, establish the current best evidence, and highlight the treatment outcomes and their predictors, in regards to healing and asymptomatic function of the treated teeth. Levels of evidence: The lecture content is supported by randomized controlled trials and prospective cohort studies.
One half-day or full-day lecture.
