One of the founding members and 4th president of the AACD, Dr. John Kanca DDS, discusses his early research papers about hardness and curing of composites written over 30 years ago. In 1989, Dr. Kanca spoke about etching dentin at the Academy of Cosmetic Dentistry meeting and was met with harsh opposition. As a pioneer in the dental industry, Dr. Kanca went on to create his own bonding solution and cementation that is now known nationwide as All-Bond.
