Emmanuel Lesaffre, Interuniversity Institute for Biostatistics and Statistical Bioinformatics, Catholic University Leuven, Belgium. and University Hasselt, Belgium; Department of Biostatistics, Erasmus MC, Rotterdam, the Netherlands Jocelyne Feine, Oral Health and Society Research Unit, Faculty of Dentistry, McGill University, Quebec, Canada.Brian Leroux,Departments of Biostatistics and of Dental Public Health Sciences, University of Washington, Seattle, USA.Dominique Declerck, School for Dentistry, Catholic University Leuven, Belgium.

"In summary, this book is very well written. Its first three parts and the final part will be invaluable to dentists who are embarking on a clinical research project for the first time. In the reviewer's opinion, Part IV is more suitable for those undertaking doctoral studies or who have significant previous research experience." (Primary Dental Care, July 2010)
