Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
ISO 3950 has assigned a meaning to most of the available combinations of two digits. As a result,
ISO 3950 cannot be expended to satisfactorily identify supernumerary teeth without introducing
significant changes to its structure. Such changes are seen as undesirable as they would create
significant implementation and data continuity issues. Meeting the need for a standard for the
designation of supernumerary teeth while avoiding the need for undesirable modifications to ISO 3950
