ISO 20888:2020 (adopted as EN ISO 20888:2020) defines a standardized vocabulary and designation system for forensic oro-dental data. It provides unambiguous terms and a hierarchical structure to describe the distinguishing features of an individual’s mouth, teeth and dental devices for forensic identification. The standard is specifically oriented toward antemortem (AM) / postmortem (PM) data exchange, reducing ambiguity in dental descriptions used by dentists and forensic odontologists during identification and disaster victim identification (DVI) operations.
Key technical topics and requirements
- Terms and definitions: A comprehensive list of forensic-focused dental terms (examples include concepts like “present tooth”) organized by forensic relevance.
- Hierarchical attribute structure: Attributes for teeth, mouth and prostheses are organized with increasing discriminative detail (e.g., material characteristics, restored tooth surface), allowing any level of description to link to broader concepts.
- Mapping to existing codes: Descriptors align with ISO 3950 tooth/location codes; items without a specific location use ISO 3950 codes 00, 01, 02. The standard is intended to be used in conjunction with ISO 1942 (Dentistry - Vocabulary) and ISO 3950 (Designation system for teeth and oral areas).
- Normative annexes: Multiple annexes define specific categories useful in forensic contexts, such as drift/malposition, impaction angulation, restorative materials and colours, endodontic obturation materials, implant types, prosthesis components, congenital and acquired anomalies - ensuring consistent terminology across examinations.
- Radiographic descriptor principles: Radiographic features are grouped into unified descriptors to ensure consistent interpretation even when similar but not identical attributes occur.
Practical applications and users
Who uses ISO 20888:
- Forensic odontologists and dental examiners performing AM/PM comparisons
- Clinical dentists preparing records likely to be used for identification
- DVI teams, coroners, medical examiners, and law enforcement in mass-casualty or cross-border identifications
- Dental software developers building odontological comparison tools and EMR/EHR systems for secure AM/PM data exchange
- Standards bodies and health-record integrators implementing interoperable dental data sets
Practical benefits:
- Improves accuracy and speed of dental identification by eliminating ambiguous terminology
- Enables standardized electronic exchange of dental records and supports automated comparison algorithms
- Facilitates multinational cooperation during DVI events
