U.S. #1135 was issued on the 100th anniversary of the founding of the American Dental Association. The group was founded in 1859 to promote oral health care and the science of dentistry.
The first meeting of the ADA was in Niagara Falls, New York, with 26 members. Since then, the association has grown to over 150,000 members. It is based in Chicago, and each month produces the Journal of American Dental Association, which includes articles about dental issues.
