Alpha Omega (ΑΩ, sometimes AO), is a professional Jewish dental fraternity.

The objectives of the fraternity are to promote the profession of Dentistry; to establish, foster, and develop high standards of scholarship, leadership, and character; to inculcate a spirit of fellowship amongst all its members; to create and bind together a body of professional people, who, by scholarly attainments, faithful service and the maintenance of ethical ideals and principles, have achieved distinction; to honor achievement in others; to strive for breadth of vision, unity in action and accomplishment of ideals; to commend all worthy deeds, and if fraternal welfare demands, to call and counsel with its members; to accept, sponsor and develop the cultural and traditional achievements of our faith; to build within our fraternity a triangle, the base of which is Judaism, the supporting sides, professionalism, and fraternalism.
