本文件定义了牙医和法医牙科专家用来描述个人口腔显著特征的术语。这些术语是根据基于口腔特征的法医方法的概念来组织的，其中许多概念是特定于识别领域的，这些概念在ISO牙科词汇的其他地方没有定义（例如“当前牙齿”）。 本文档的分层结构被设计成描述牙齿、口腔和假体/矫形器的属性，其具有递增级别的鉴别特征(例如，材料特征、修复的牙齿表面)，并且可以将属性的任何级别的描述与最全面的概念联系起来。 本文件旨在用于死前和死后文件之间的数据交换，并消除用于描述个人口腔的术语的歧义。 本文件旨在与ISO 1942和ISO 3950一起使用。

This document defines the terms used to describe the distinctive characteristics of an individual's mouth by dentists and forensic dental experts. These terms are organized by concepts based on a forensic approach to the characteristics of a mouth, with many concepts specific to the identification domain that are not defined elsewhere in ISO dentistry vocabularies (e.g. "present tooth"). The hierarchical structure of this document is designed to describe attributes of a tooth, the mouth and a prosthesis/orthosis with increasing levels of discriminative characteristics (e.g. material characteristics, restored tooth surface) and the possibility to connect any level of description of an attribute with the most comprehensive concept. This document is intended to be used for data exchange between antemortem and postmortem files and remove ambiguity on the terms used to describe an individual's mouth. This document is intended to be used in conjunction with ISO 1942 and ISO 3950.
