The official emblem of dentistry was adopted by the American Dental Association in November of 1965. The design uses as its central figure a serpent entwined about an ancient Arabian cautery, in the manner of the single serpent of Aesculapius, the Greek god of Medicine, coiled around a rod. The Greek letter Delta for dentistry and the Greek letter Omicron for odont ( tooth ) form the periphery design. In the background are thirty two leaves and twenty berries, representative of the 32 permanent teeth and twenty children's teeth.
