History

Delta Sigma Delta's inception came when Louis James "Lou" Mitchell and Charles William Howard, dental students at the University of Michigan School of Dentistry in Ann Arbor, were invited to join the medical fraternity Nu Sigma Nu. They declined, instead opting to form the school's first professional dental fraternity.
On, these two and five others from the dental school met at Mrs. Slattery's boarding house, located at #10 North State Street in Ann Arbor, Michigan. Along with Howard and Mitchell, the fraternity's founders were Francis Eugene Cassidy, Lyndall Llewellyn Davis, Clarence James Hand, Louis Manning "Jamie" James, and Ezra Lincoln Kern. Delta Sigma Delta was the first dental fraternity in the world.
Dr. L. L. Davis established the Beta chapter at the Chicago College of Dental Surgery after establishing his dental practice in Chicago. Within a month of each other, Epsilon chapter was chartered at the University of Pennsylvania School of Dental Medicine, followed by Gamma chapter at Harvard University.
After graduation, the fraternity's founders took positions in multiple cities. This led to the formation of a supreme or alumni chapter, in Detroit, Michigan in 1895.

Symbols

The Greek letters ΔΣΔ represent the letters D.D.S. of the dental degree, although with a transposed sequence. The fraternity's colors are blue and garnet. Its motto is "Knowledge, Strength, Justice".

Governance

The Supreme Chapter is the fraternity's administrative or governing body. A Council of Graduate Chapters oversees the graduate chapters. The European Continental Chapter oversees the European graduate chapters and the Australia/New Zealand Chapter oversees the graduate chapters there.

Chapters

As of 2021, there were 44 active chapters. Undergraduate or collegiate chapters are located at dental schools, while graduate chapters are located in population centers throughout the United States and in Canada, Europe, Australia, and New Zealand.
