Keynotes and symposia


Wednesday 9 May 2018

Time Agenda Item
09:30 – 10:30 Keynote 1: Standardizing definitions of disease and treatment outcomes
Speaker: Prof. Brian Leroux, University of Washington, Seattle, United States

One of the challenges in many areas of oral health research is the lack of consensus on measures of disease outcomes and diagnostic rules. This problem can inhibit research progress by limiting the impact of research on clinical practice, producing inconsistent results between studies (thereby contributing to the replicability crisis), and creating difficulties in combining studies in meta-analyses. In this talk I will discuss the issues involved with choosing outcome variables in a variety of settings including disease surveillance, etiologic research, and clinical trials. Some constructive suggestions for moving forward will also be described.

14:00 – 15:00 Keynote 2: Statistical methods in meta-analysis
Speaker: Prof. May CM Wong, University of Hong Kong, Hong Kong

A key element in most systematic reviews is the synthesis of the data. Meta-analysis is the process of combining results or data from separate studies statistically to estimate the overall effect estimates with increasing power and precision. This talk will review the methods used in meta-analysis and the appropriate application of meta-analysis in systematic reviews. Some recent development such as prospective meta-analysis, individual participant data and network meta-analysis will also be discussed.

Thursday 10 May 2018

Time Agenda Item
09:00 – 10:00 Keynote 3: Quality of systematic reviews (SR)
Speaker: Prof. Ian Needleman, UCL Eastman Dental Institute, London, United Kingdom

Systematic reviews (SR) shout the promise of highest quality evidence for healthcare. Unfortunately, reality is somewhat different. SR are complex, difficult research endeavours with evolving methodology. Across healthcare, including oral health, the evidence is clear that the quality of SR is often inadequate to use their findings with confidence. In this session, I will review what we know about SR quality, explore what we might do differently and consider their future development.

14:00 – 15:30 Symposium: How EBD impacts on clinical practice
This symposium will review on EBD in China, how EBD impacts on the practice of periodontal care; and shapes the national dental public health policy in Thailand.

Prof. Maurizio Tonetti, University of Hong Kong, Hong Kong Dr. Chunjie Li, Sichuan Univeristy, China Dr. Waranuch Pitiphat, Khon Kaen University, Thailand

Friday 11 May 2018 (Half day program till 12:30pm)

Time Agenda Item
09:00 – 10:30 Symposium: EBD in dental curriculum
This symposium will discuss the challenges and opportunities in EBD training in the dental undergraduate curriculum.

Prof. Edward Lo, University of Hong Kong, Hong Kong

Prof. Analia Veitz-Keenan, New York University, United States Dr. Jolanta Aleksejūnienė, University of British Columbia, Canada
11:00 – 12:00 Keynote 4: The editor’s perspectives on EBD/SR
Speaker: Prof. Helen Worthington, Cochrane Oral Health, Manchester, United Kingdom

The methods for Evidence Based Dentistry and systematic reviews have been well developed over the last 20 years. However many published systematic reviews still have methodological errors, and the guidelines produced using systematic reviews are often misleading, due to the misuse and misinterpretation of the evidence. In oral health one of the main statistical areas of concern is unit of analysis errors due to the common use of split-mouth, cross-over and cluster trials, with inappropriate analysis of the data. This and other areas of concern arise in both primary and secondary research and can lead to inappropriate recommendations.
