Full title and description

ISO 10394:2023 — Dentistry — Designation system for supernumerary teeth. This international standard defines a concise designation system for recording and communicating the presence and location of supernumerary (extra) human teeth using a short alphanumeric code, intended for use in clinical records, research, dental software and data exchange.

Abstract

This document establishes a system for the designation of supernumerary teeth in humans using two alphanumeric characters. The standard provides the rules, examples and minimal notation required to identify supernumerary teeth unambiguously in clinical and electronic records.

General information

Scope

Specifies a short, two-character alphanumeric designation system to identify supernumerary teeth in humans. The scope covers the notation rules, examples and assignment principles needed to place a supernumerary tooth within an established tooth-location framework so it can be recorded consistently in dental charts, reports and software. The standard is limited to designation (identification and notation) and does not address clinical treatment or management.

Key topics and requirements

• Definition of a two-character alphanumeric code format for each recorded supernumerary tooth.
• Rules for assigning the code based on the tooth’s anatomical location relative to normal dentition.
• Guidance and examples illustrating assignment in common clinical situations (including midline and overlapping positions).
• Principles to ensure the system is compact, computer-friendly and suitable for inclusion in dental records and messaging.
• Notes on interpretation and limits of the designation system (what is and is not covered by the code).

Typical use and users

Used by general dentists, orthodontists, oral and maxillofacial surgeons, pediatric dentists, dental hygienists, clinical researchers and vendors of electronic dental records and imaging/reporting software. Typical applications include charting supernumerary teeth in patient records, reporting findings in clinical studies, and exchanging standardized dental data between systems.

Related standards

Closely related to general tooth-designation standards such as ISO 3950 (Dentistry — Designation system for teeth and areas of the oral cavity). National and regional bodies may publish adopted or translated versions (for example EN/DIN/UNE adoptions) to align with local publication practices.

Q: What does it cover?

A: It covers the notation format, rules and examples for assigning a short code to each supernumerary tooth so that location and identification are consistent across records and systems. It does not cover clinical management or treatment.

Q: Who typically uses it?

A: Dentists and dental specialists (orthodontists, oral surgeons, pediatric dentists), dental researchers, and vendors/implementers of electronic dental records and imaging/reporting systems.

Q: Is it current or superseded?
