Through the development of fellowship and understanding, the Academy endeavors to create opportunities for service in order to assist in the establishment of a world at peace."


Pierre Fauchard Academy Fellowship
"It was between 1650 and 1800 that the science of modern dentistry developed. And in 1728 Pierre Fauchard, who was widely acknowledged as the "Father of Modern Dentistry" published "LeChirurgien Dentiste" which contained detailed information about all aspects of contemporary dentistry. It was his lead that encouraged others. For example, before the end of the century in England the distinguished surgeon, John Hunter, published his book
"The Natural History of the Human Teeth" and the first course of dental lectures was established
at Guy's Hospital
in London."

The mission of Fellows in the Pierre Fauchard Academy is to consistently focus on professionalism, integrity, and ethics worldwide; by conduct as worthy role models; by the advancement of dentistry to the highest level; by supporting and honoring colleagues for their distinguished work, research, contributions, and public service; and by providing excellence in programs, education, and leadership in oral health care.

Fellows shall be ethical dentists that have made outstanding contributions to the art and science of dentistry or to society. They must be in good standing of the American Dental Association or the equivalent association in other countries. Fellowship is by invitation only.
