Omicron Kappa Upsilon is the national honor society in dentistry, symbolizing the outstanding scholarship and character of graduating senior dental students, as determined by dental school faculty. The organization is generally referred to as the “Phi Beta Kappa” of dentistry, with membership restricted to dentists recognized in attaining a high grade point average upon graduation from dental school. More recently, OKU has broadened its sphere of influence beyond scholarship and includes such initiatives as service, mentorship, outreach, and research.
