A useful textbook represents the outcome of pragmatism versus idealism. Lengthy qualifications and arguments are simply not instructive at the undergraduate level. The broad contributions of authors in this edition provide a balanced compilation of information which is firmly grounded. They come from diverse educational and clinical backgrounds and yet have produced a cohesive and consistent resource. I would like to thank them all. The book reflects evidence-based mainstream orthodontic teaching and provides the stimulus for progressive learning throughout the dental student’s journey to graduation. The material is comprehensive but not overwhelming.
