Research summary
Periodontology and laser applications in dentistry

Research

Dr Leichter's prime areas of research are periodontology, dental implants, dental trauma and laser applications in dentistry. His multi-disciplinary research has resulted in publications in high ranking international peer reviewed journals in periodontology, endodontics, cariology and dental materials. His clinical research into lasers in periodontology has established that Er:YAG lasers are the only monotherapy for the treatment of periodontitis that is equivalent to the 'gold standard' of scaling and root planing. Work with dental lasers is opening up novel treatment strategies for the treatment of peri-implantitis as well. The scope and quality of Dr Leichter's research has been recognized in the way of being invited to act as a reviewer and editor for peer reviewed dental journals and in invitations to present his research in New Zealand, Australia, Japan and in the US.
