ANSI/ADA 78-2006
This standard specifies the dimensions and requirements for prefabricated metallic or polymeric-based cones suitable for use in the obturation of a root canal system restoration. It also specifies numerical systems and a color coding system for designating the sizes. This revision includes harmonization with the action of the ISO working group for Endodontic Materials by moving reference of biological aspects from the body of the document to the introduction and elimination of the Type and Class distinctions. This specification, as revised, is in harmony with ISO 6877 except for the designation utilized for the various diameters.
