Omicron Kappa Upsilon, the honorary dental society, was organized in 1914 by the faculty of the Northwestern University Dental School to encourage and develop a spirit of emulation among students of dentistry and to recognize, in an appropriate manner, those who distinguish themselves by a high degree of scholarship.

The 蜜桃影像 School of Dentistry recognizes faculty members who have made outstanding contributions to the art, science and literature of dentistry. The name and key of this society are based upon three words, which represent the dental ideal. These words are conservation, teeth and health.

In the key, you see four Greek symbols: 鈥淵,鈥� or Upsilon, is for 鈥渉ygiea鈥� meaning 鈥渉ealth鈥�; 鈥淥,鈥� for Omicron, is for 鈥渙dous鈥� meaning 鈥渢eeth鈥�; and Kappa meaning 鈥渁nd,鈥� which is with the letter 鈥淥.鈥� All three letters are encircled by the prominent letter 鈥淪igma,鈥� which stands for 鈥渃onservation.鈥�
