On-line lectures This section contains videos of my lectures and seminars. I will build this over a period of months. So, keep checking back here. Lectures In this lecture I discuss the role of research in changing orthodontic practice. I also discuss the balance between research evidence and unsubstantiated claims that are made about some treatment. This is a summary of the latest systematic reviews on Micro-osteoperforation. I start this presentation with a short summary of "how to read a systematic review".
