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).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any

patent rights identified during the development of the document will be in the Introduction and/or on

the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the World

Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

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 therefore

requires the intoduction of a standard that is independent of ISO 3950.

This designation system for supernumerary teeth retains the two-character format of ISO 3950 to

maximize compatibility with existing forms, software and messaging systems while still satisfying the

requirements identified as essential to the success of the designation system originally drawn up by the

FDI World Dental Federation and approved by the World Health Organization (WHO) and Technical

committee ISO/TC 106, Dentistry, i.e.:
a) simple to understand and teach;
b) easy to pronounce in conversation and dictation;
c) readily communica
