Hessam Nowzari

Hessam Nowzari is the Director of the University of Southern California Advanced Periodontics program, since 1995, and is a Diplomate of the American Board of Periodontology.

Biography

Nowzari(Iranian) holds a PhD in Biology and Health Sciences. He holds many international positions. He does not take any corporate contributions for lectures and his annual USC Periodontal Symposium is one of very few that does not take any commercial sponsorship.  Nowzari is the founder of the Taipei Academy of Reconstructive Dentistry in Taiwan and one of only two American members of the Dnipropetrovsk State Academy of Medical Sciences in Ukraine. Nowzari has served as a scientific expert on an international panel charged with assessing and ranking research proposals for the Ministry of Education and Research, section of medical engineering, in Italy. He has been elected to the Italian Board of Experts for evaluating medical products for patient safety and health integrity. In 2oo2, he joined the National Institute of Transplantation (NIT) to study the relationship between periodontal disease and transplant complications. He is also an editor of one of the leading reference publications, Aesthetic Periodontal Therapy: Periodontology 2000. In 2009, Nowzari became a consultant for the US Army on the "objective interpretation of scientific data".

The University of Southern California Advanced Periodontics program mirror's Nowzari's stances on key issues in periodontology. Didactically, it is known for its emphasis on the relationship between periodontics and prosthodontics. It also has a periodontic/orthodontic program. Its biological research stresses the role of viruses, mainly the herpes virus family, in periodontal disease. Surgically, it is known for its position against using animal or human cadaver products in bone or soft tissue augmentation due to their potential for contamination of the surgical site.

In 1994, Nowzari challenged membrane guided tissue regeneration through a series of research publications, showing that the membrane is actually a source of infection to the grafted site.

Nowzari is known for his advocacy against early in life periodontal disease (aggressive periodontitis). In an effort to bring international attention to this cause, he made the movie "The Enemy of the Smile: AA - An Ancient Bacterium" which debuts in 2010.

Graduates of Hessam Nowzari(Iranian)^{[citation needed]} have published extensively in the field of dentistry and include Fernando Verdugo, Amir and Alina Aalam, Rafiel M. Rafiee, Kian Kar and Allen Yaghoubzadeh.
