Synopsis:
Typical whitening systems are designed to provide what dentists and patients want, however these “wants” typically fly in the face of what is physically and chemically possible. For whitening success, tooth color molecules must be broken down by radicals produced by peroxide, however, there are a myriad of stumbling blocks to achieving this goal. With most current whitening systems, peroxide gels may already be degraded when received because of inadequate handling and lack of refrigeration by whitening product companies; gels may be chemically altered to lengthen shelf life, leading to acidic pH, higher osmolarity, higher sensitivity and less effectiveness of the products; and they typically have inadequate continuous activity to accomplish thorough cleansing and whitening of tooth structure. In-office whitening lacks the time necessary to thoroughly degrade color molecules, and antioxidants found in saliva and sulcular fluid rapidly seep under and into whitening trays, destroying peroxide on contact.

Description of Speaker:
Dr. Rod Kurthy practices in Mission Viejo, California. He graduated with highest honors from Fairleigh Dickinson University School of Dentistry in 1978, and completed a GP residency at Newark Beth Israel Medical Center. Dr. Kurthy’s 35 years of research and development include laser and surgical periodontal bone regeneration; endodontic surgery, including bone regeneration and repair of resorptive lesions; teeth whitening; teeth sensitivity; and development of several cosmetic techniques and impression techniques, to name a few. His first participation in periodontal research was in 1976, and teeth whitening in 1977. He is an international lecturer and author of five popular clinical and dental marketing books. He is the recipient of awards and accolades including the Mosby Scholarship Award; FDU Prosthodontics and Pediatric Dentistry Awards; the Omicron Kappa Upsilon Gold Key Award; a commendation from the Chief Attorney of the United States Department of Defense for his role in supporting patients’ rights in disputes with insurance carriers; and in March, 2005, he was selected as the most respected member of Dentaltown.com by more than 60,000 of his peers. Kurthy has authored numerous articles; is frequently interviewed by dental journals and consumer magazines; has appeared numerous times on the covers of several widely-read dental journals in the USA; has been featured six times on national tape interview series; and is a consultant to magazines such as People Magazine and has been a feature writer for Oxygen Women’s Fitness magazine. He has been interviewed and featured numerous times in national media, and has been the personal dentist for the United States Men’s World Cup Soccer Team. Most recently, Kurthy has been widely known for his KöR Whitening Deep Bleaching System.

Fantastic article Rod! I have to admit it has been at least 25 years since I read about chromophores and did not remember that they are very specific magnetic fields between certain atoms within molecules!! In fact I am wondering if I ever learned about them in college!! LMAO…
Rod: Great overview of the chemistry of bleaching

Rod, Nice course with a great consolidation of some technical chemical factors. Having a chemistry undergrad degree makes a lot of "bondodontics" easier to understand for me. Your discussion of the whys of poor results is presented in a cogent manner. Thanks for sharing! Doug Carlsen DDS.....financial writer for Dentaltown, yet a science geek at heart!
