Flow-Diagram Completion Task for Dental Record Analysis

Introduction and Purpose

This Knowledge Providing Task has been specifically designed for learners pursuing the LICQual Level 7 Postgraduate Diploma in Forensic Odontology (PgDFO), focusing on the critical unit of Human Identification and Dental Records. The vocational nature of forensic odontology demands that practitioners possess not only theoretical knowledge but also practical competency in understanding and executing complex identification processes that are routinely encountered in real-world forensic scenarios.

The purpose of this flow-diagram completion exercise is to develop your practical understanding of the sequential processes involved in forensic dental identification work. In professional practice, forensic odontologists must navigate intricate workflows that involve multiple stages of inspection, analysis, comparison, reporting, and escalation.

Key objectives of this exercise include:

• Understanding systematic process flows in forensic dental identification
• Applying UK legal and regulatory frameworks to practical scenarios
• Developing competency in decision-making at critical workflow junctions
• Maintaining compliance with Forensic Science Regulator standards
• Integrating documentation and quality assurance throughout processes

Flow diagrams serve as essential tools in forensic practice because they provide clear visual representations of complex processes, ensure consistency in approach across different cases, facilitate quality assurance, and provide defensible documentation of methodologies used in casework. In the context of UK forensic practice, where adherence to standards set by bodies such as the Forensic Science Regulator, the General Dental Council, and various criminal justice agencies is mandatory, understanding these process flows is not optional but essential for competent practice.

This exercise aligns with unit learning outcomes:

• Assess dental records and radiographs for accurate human identification
• Apply techniques for identification in mass disaster, criminal, and medico-legal cases
• Evaluate the accuracy and reliability of different identification methods
• Maintain detailed and compliant documentation of forensic findings

The competency-based approach of this task means you will be assessed on your ability to apply knowledge in practical contexts rather than simply recalling theoretical information. You will need to demonstrate understanding of UK-specific legal and regulatory frameworks, including the Human Tissue Act 2004, the Coroners and Justice Act 2009, the GDPR as implemented through the Data Protection Act 2018, and guidance from the Forensic Science Regulator.

Initial Case Receipt and Preliminary Assessment in Forensic Odontology Practice

When forensic odontology cases are received in UK practice, the initial reception and preliminary assessment phase establishes the foundation for all subsequent forensic work. This critical workflow begins the moment a formal request is received and continues through comprehensive preliminary evaluation.

Typical requesting authorities in UK practice:

• Her Majesty’s Coroner (under Coroners and Justice Act 2009)
• Police Major Crime Units or Homicide and Major Enquiry Teams (HMETS)
• Disaster Victim Identification (DVI) teams following UK DVI protocols
• Defense solicitors in criminal cases requiring dental evidence analysis

The forensic odontologist receiving such requests bears immediate responsibility to verify the legitimacy and proper authority of the request. Under the Human Tissue Act 2004, any retention and examination of human tissue including dental remains requires either appropriate consent or legal authority. This is typically provided through coronial authority for deaths under investigation or under the Police and Criminal Evidence Act 1984 for criminal investigations.

Initial documentation review must assess:

• Ante-mortem dental records availability and completeness
• Post-mortem dental examination reports or preliminary findings
• Radiographs (both ante-mortem and post-mortem)
• Photographic documentation of dental features
• Physical evidence such as dental appliances or extracted teeth
• Chain of custody documentation for all materials

Chain of custody considerations begin immediately at reception. The practitioner must implement rigorous continuity procedures ensuring that all evidence is logged with detailed descriptions, condition is thoroughly documented, secure storage with environmental controls is provided, and all access is controlled and logged. These requirements align with Forensic Science Regulator guidance and maintain evidential integrity for court proceedings.

The preliminary assessment requires determining:

• Case type: identification of unknown remains, verification of presumed identity, bite mark analysis, or age estimation
• Adequacy of available materials for meaningful examination
• Physical condition of post-mortem material considering decomposition, fire damage, or trauma
• Competency scope: whether case requires specialist consultation
• Timeframe alignment with investigative requirements and available resources

Quality of available dental records must be assessed according to criteria including completeness of documentation, recency relative to estimated time of death, clarity and diagnostic quality of radiographs, presence of detailed charting documenting restorations, and presence of unique identifying features. In UK practice, dental records may come from NHS dental practitioners or private practitioners, and format and completeness can vary significantly.

Risk assessment at preliminary stage considers:

• Whether expedited examination is justified based on investigative priorities
• Health and safety concerns requiring special handling protocols
• Cultural or religious considerations impacting examination timing or methods
• Media attention or public interest creating additional case pressures
• Resource allocation and capacity planning for complex cases

Documentation generated during initial reception and assessment forms the foundation of the case file and must meet Forensic Science Regulator standards. This includes recording date and time of receipt, requesting authority and reference numbers, complete inventory of materials, condition upon receipt, initial observations about examination scope, and any immediate concerns or limitations identified.

Ante-Mortem Dental Record Collection and Authentication Procedures

The collection and verification of ante-mortem dental records represents one of the most challenging yet critical phases of forensic dental identification work. Unlike some forensic disciplines where evidence is collected at scenes through controlled procedures, dental records must be obtained from multiple healthcare providers who maintain independent record systems, may be geographically dispersed, and operate under different data protection frameworks.

Intelligence gathering to identify treating dentists typically involves:

• Interviewing family members or associates of the deceased or missing person
• Reviewing personal effects such as appointment cards or dental practice correspondence
• Checking medical records for references to dental treatment
• Examining financial records for payments to dental practices
• Consulting with the deceased’s general medical practitioner who may have referral records

In the UK, individuals may have received treatment from multiple sources over time including NHS dental practices operating under NHS contractual frameworks, private dental practices, dental hospitals and teaching institutions, military dental services for
armed forces personnel, or prison dental services for those with custody histories. Each source maintains records in different formats with different retention policies, requiring tailored approaches.

Legal authority for obtaining dental records in UK coronial investigations is provided primarily through Section 19 of the Coroners and Justice Act 2009, which gives coroners broad powers to request documents relevant to their investigations. This section states that a coroner may require any person to produce any document which the coroner believes is relevant to the investigation, and the person must comply with such a requirement. For police-led criminal investigations, similar powers exist under the Police and Criminal Evidence Act 1984, though in practice most dental record requests in identification cases are made under coronial authority.

Dental practitioners receiving record requests must balance:

• Legal obligation to comply with properly authorized requests
• Professional duty of confidentiality to patients under General Dental Council standards
• Requirements to verify legitimacy of requests before releasing records
• Data protection obligations under GDPR and Data Protection Act 2018

The forensic odontologist must provide clear guidance to investigating officers about what constitutes useful dental records for identification purposes. Many police officers and coroner’s officers have limited understanding of dental terminology and record formats, and may accept incomplete materials if not properly briefed.

Effective record requests should specify:

• Written clinical notes documenting all dental treatment received
• Radiographs in their original format including bitewing, periapical, and panoramic films
• Dental charts showing location and type of all restorations and missing teeth
• Laboratory prescriptions for crowns, bridges, or dentures
• Photographs of dental work or the patient’s smile if available
• Treatment plans or estimates documenting proposed or completed work

Once records are received, the verification process begins as a critical quality control step. The forensic odontologist must verify that records genuinely relate to the individual in question through several systematic checks.

Authentication procedures include:

• Verifying practice letterhead, official stamps, or digital signatures are present
• Confirming authorized practitioner signature on records
• Checking secure transmission methods were used for confidential data
• Contacting the dental practice directly to confirm record authenticity if any doubts exist

Patient identity verification requires:

• Comparing demographic data (name, date of birth, address) with known information about missing person
• Ensuring dates of treatment are consistent with the presumed timeline
• Confirming with the treating dentist that records relate to the named patient
• Reviewing for indicators of mixed or misfiled records such as inconsistent handwriting or contradictory entries

Record quality assessment requires clinical judgment about whether available records provide sufficient data for identification purposes. Not all dental records are created equal – some practitioners maintain meticulous records with comprehensive charting and regular radiographs, while others maintain minimal documentation that barely meets professional requirements.

Quality assessment considers:

• Completeness: are all treatment episodes documented or are there gaps?
• Radiographic quality: are images diagnostic or degraded, properly labeled and dated?
• Recency: how long before the estimated time of death were records created?
• Unique features: are there unusual restorations, rare dental work, or anatomical variations?
• Consistency: do records from multiple practitioners align or show contradictions?

Records that are very old, incomplete, or of poor quality may still be useful but will affect the strength of conclusions that can be drawn from comparative analysis. The forensic odontologist must honestly assess limitations and communicate these to investigating authorities.

Transcription to standardized format is essential for systematic comparison. While original records must be preserved for evidential purposes, working with standardized dental charts using FDI (Fédération Dentaire Internationale) notation allows for consistent comparison methodology. The FDI system uses a two-digit numbering system where the first digit represents the quadrant and the second represents the tooth position.

Transcription process involves:

• Converting various notational systems to standardized FDI format
• Creating clear dental charts showing all restorations, missing teeth, and anomalies
• Documenting restoration types, materials, and surfaces involved
• Recording any pathology, unusual anatomy, or distinctive features
• Creating comparison-ready formats that facilitate side-by-side analysis

This transcription process requires care and should ideally be peer-reviewed to minimize transcription errors that could lead to false exclusions or incorrect identifications. Errors in transcription have been identified as contributing factors in some misidentification cases internationally, highlighting the importance of quality control at this stage.

Post-Mortem Dental Examination and Systematic Documentation

The post-mortem dental examination is the cornerstone of forensic dental identification work and requires systematic methodology, meticulous attention to detail, and comprehensive documentation that meets both scientific and legal standards. Unlike clinical dental examinations conducted on living patients in controlled practice environments, post-mortem examinations must contend with various challenging factors.

Challenges in post-mortem dental examination include:

• Decomposition affecting soft tissue integrity and visibility of structures
• Fire damage potentially causing heat-related changes to dental materials and tooth structure
• Traumatic injury that may have fragmented or displaced dental structures
• Environmental degradation from water immersion, burial, or exposure
• Absence of normal soft tissue structures that protect and obscure certain features
• Rigor mortis affecting jaw positioning and access to oral cavity

The examination environment itself requires careful consideration and appropriate preparation. In the UK, most post-mortem dental examinations are conducted in mortuaries operated by NHS hospital trusts under contract to HM Coroners, or in dedicated forensic pathology facilities serving multiple jurisdictions.

Essential environmental requirements include:

• Adequate lighting for detailed dental examination, often supplemented with portable examination lights
• Appropriate instrumentation including dental mirrors, explorers, periodontal probes, and extraction forceps if needed
• Facilities for taking post-mortem dental radiographs with proper positioning equipment
• Photography areas allowing proper documentation with appropriate backgrounds and lighting
• Compliance with health and safety requirements including COSHH Regulations 2002
• Human Tissue Act 2004 compliant storage and handling of human remains
• Personal protective equipment appropriate to biological hazards present

Before commencing physical examination, the forensic odontologist should review all available contextual information. This includes understanding the circumstances of death and how these might affect dental structures, being aware of the estimated postmortem interval and associated decomposition changes, knowing about environmental factors that may have affected remains, reviewing any initial findings from the pathologist conducting the overall post-mortem examination, and understanding what specific questions the dental examination needs to address.

The systematic dental examination follows established protocols designed to ensure no features are overlooked and all findings are comprehensively documented. The examination typically progresses through a series of sequential stages, each building upon the previous observations.

External examination components:

• Overall assessment of facial structure and skeletal morphology
• Evaluation of jaw relationships and occlusal patterns
• Identification of any trauma to facial bones or jaws
• Assessment of decomposition or damage affecting the oral region
• Photographic documentation of overall condition before detailed examination

Intra-oral examination systematically documents:

• Presence or absence of each tooth using FDI notation system
• Condition of each tooth present including intact, fractured, or damaged
• All restorations with detailed description of type, material, extent, and surfaces involved
• Quality and characteristics of dental work including margins, contours, and finishing
• Any unique or unusual features of restorations that may have identification value

Dental restorations provide some of the most valuable identifying features because treatment patterns and techniques vary between practitioners and over time. The forensic odontologist must document restorations with sufficient detail that they can be meaningfully compared with ante-mortem records.

Restoration documentation includes:

• Material type: amalgam, composite resin, glass ionomer, gold, porcelain, or other materials
• Surfaces involved using standard notation: occlusal (O), mesial (M), distal (D), buccal (B), lingual (L)
• Extent of preparation and restoration size relative to tooth
• Quality of work including margin adaptation, anatomic contour, and surface finish
• Any distinctive features such as unusual cavity designs or material combinations
• Presence of pins, posts, or other retention devices visible clinically or radiographically
