Introduction
The establishment of a positive identification of an unidentified individual by the comparative
dental analysis of a forensic odontologist requires submission of supporting documentation from the
dental professionals who treated the patient. This information includes dental treatment records,
radiographs, photographs and dental casts, should be submitted to the appropriate authority and is
referred to as antemortem dental data (AM). Currently, the vast majority of antemortem dental data
and associated attachments are submitted on paper and by radiographic film, however, the ultimate
goal is to create a standardized electronic format for the transfer of this data. Due to varying methods
of documentation and recording systems an organized list of standardized dental terminology would
be useful. Submission of ambiguous information due to a lack of harmonization can increase the time
required to establish the identification through dental means.
The Disaster Victim Identification (DVI) community, due to the number of victims and the number of
countries of origin of the victims, will benefit from this international standardized forensic dental data,
by using standardized terminology of useful concepts.
Background
Current odontological comparison software is based on the concept of restoration comparison. Utilizing
each tooth as a field, comparison and/or elimination queries and advance sorting algorithms creates a
ranking of possible matches to aid the Forensic Odontologist in the initial records comparison. Biometric,
familial, radiographic and visual information support the likelihood of a match. By standardizing the
descriptors used to describe this information the likelihood of identifying an individual based on the
Forensic Odontologists data increases.
Principle
Characteristics of the oral cavity can be grouped in three sets of data:
Tooth data set describing teeth one by one, together with periodontal tissues
Mouth data set describing intra and extra oral characteristics of the mouth with the exclusion of teeth,
dental prosthesis and dental orthoses
Prosthesis and orthoses data set describing dental prosthesis and dental orthoses appliances
For each data set, characteristics are organized with increasing precision in the description of an
attribute, allowing to find a match independently of the granularity of the information. For example, if
an antemortem record informs that such tooth is restored, without any precision on the material used
and the surfaces concerned, a postmortem record describing the same tooth with all the characteristics
of the restoration i.e.: surface(s) and material(s), it is still a match at the broader level (restored tooth).
Many descriptors of a tooth are determined from radiographic interpretation; certain “similar”
radiographic attributes are grouped together into single unified descriptors. This should allow
unambiguous interpretation of a tooth attribute and ensure that a radiographic attribute may be
described by a single unified attribute. Generally, consistency of assigning a single attribute to a
radiographic feature is utilized in this standard in order to create unambiguous descriptors even at the
expense of combining similar, but not identical, attributes.
The permanent dentition takes priority when both the primary and permanent teeth are present if both
are concurrently visible in the mouth however the presence of the primary tooth should also be noted.
The pertinence of these descriptors should be weighted with the time differences between the date of
the records and the presumptive date of recording of the current data.
If a descriptor involves multiple teeth, then that descriptor shall be utilized for all the teeth involved.
The tooth data set descriptors may be utilized for both antemortem data and postmortem data. The
purpose of this data set is to define a common nomenclature to common attributes of a tooth. Because
no data set may completely describe all unique attributes of a tooth, additional fields have been added
© ISO 2019 – All rights reserved v

---------------------- Page: 7 ----------------------
oSIST prEN ISO 20888:2019
ISO/DIS 20888:2019(E)

to allow for the description of less common attributes. Care should be exercised in the use of these
additional fields since there is no guarantee that they would be understood by software that would be
utilized postmortem.
The mouth data set descriptors may be utilized for both antemortem data and postmortem data. The
purpose of this data set is to define a set of descriptors for “mouth specific” information. This should
include all skeletal findings not included on the tooth data set as well as any appliances that either restore
teeth or correct or stabilize orthodontic or skeletal abnormalities. It should also include biological
structures (excluding supernumerary teeth that are dealt with in the tooth data set descriptors) that
are outside dental norms, as well as any other information that should aid in identifying individuals.
The prosthesis data set descriptors may be utilized for both antemortem data and postmortem data. The
purpose of this data set is to define a set of descriptors to describe a dental prosthesis (3.7) and dental
orthoses (3.8) separately from the underlying tooth structure.
Rationale
A great deal of information is gathered during the course of dental evaluation and treatment. Forensic
Odontologists charged with the task of identifying individuals requires comprehensive information in
order to prove or disprove identification. While much of the information gathered by the dentist may
not aid in claims adjudication, it is not possible to predict in advance what item or items in the dental
record might be conclusive in identification. Although no standard exists to establish documentation
requirements for the submission of antemortem dental information for identification, this standard is
designed to fill that void.

DRAFT INTERNATIONAL STANDARD ISO/DIS 20888:2019(E)
Dentistry — Terminology for forensic oro-dental data
1 Scope
This international standard provides dentists and forensic dental experts with an organized system of
concepts to describe the distinctive characteristics of an individual’s mouth. The chosen system is based
on a forensic approach of a mouth’s characteristics, with many concepts specifics to the identification
domain that are not defined elsewhere in ISO dentistry vocabularies (e.g. “present tooth”).
The hierarchical structure of the standard 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 standard is intended to be used for data exchange between antemortem and postmortem files,
without any ambiguity on the terms used to describe an individual’s mouth.
