Forensic Odontology Quiz

Medico-legal Investigation

• Forensic medicine applies medical knowledge to legal issues, aiding courts in legal proceedings. It's related to civil law and healthcare provision.

• Forensic medicine is divided into clinical (living patients) and pathological (deceased) forensic medicine. Forensic odontology applies dental science.

• Forensic science uses various methods like fingerprints, toxicology, serology (blood), DNA, trace evidence, ballistics, fire and explosion, marks, scratches, forgeries, cybercrime and photography. Forensic anthropology is also used.

• Investigation of death principles include circumstances leading to death, scene of death and examination of the body.

• Aims of death investigations include accurate death/injury certifications, statistics, criminal justice (crime detection) and civil justice (resolving disputes).

• Medico-legal systems for investigating death are in place when cause is unnatural, overtly criminal, or suspicious. Various legal officers involved (e.g., coroners, medical examiners, magistrates).

Investigation of Death Principles

• Circumstances leading to death
• Scene of death examination
• Examination of the body
• The death certificate is intrinsically linked to all these principles.

Aims of Death Investigation

• Accurately certifying death and bodily harm
• Comprehensive statistical data collection
• Assisting in criminal justice—identifying perpetrators, prosecution of crimes, protecting the innocent.
• Assisting in civil justice—settling estates, resolving disputes (e.g., insurance claims)
• Protecting public safety—identifying safety hazards and preventable deaths.
• Providing information to the public—explaining the cause and circumstances of death, particularly next of kin.

Deaths Reported to the Magistrate (Guidelines)

• Deaths that are uncertified (no proper record).
• Those due to violence, suspicions, and unexplained causes.
• Deaths in legal custody
• Deaths in mental hospitals
• Accidents involving vehicles (cars, ships, aircraft).
• Accidents in public places (including hospitals).
• Deaths by drowning
• Deaths in fires or explosions
• Unexplained deaths of children
• Possible suicides.

Deaths to Be Investigated (Specifics)

• Death in a place of imprisonment
• Death in police custody
• Death in a designated hospital

Manner of Death

• Natural
• Unnatural (accidents, suicides, homicides)
• Uncertain/Undetermined

Manner vs Cause vs Mechanism

• Manner: Legal categorization of death (e.g., natural, accidental)
• Cause of death: Medical condition (e.g., stroke, cancer)
• Mechanism of death: Physiological event that results in death (e.g., cardiac arrest)

Case 1: Fire Victim Identification

• The importance of identifying a victim (ethical, humanitarian, criminal, civil obligations).
• Information collected from the scene (position of body, personal effects, and other key features).

Case 1: External Examination

• General characteristics (height, weight, build)
• Age (fontanelles or ossification centres and teeth)
• Sex (skull and pelvis)

Case 1: Victim's Condition at Fire

• Carboxyhaemoglobin measurement
• -Carbon monoxide (CO) poisoning exhibits characteristic cherry-pink discolouration of skin.
• Presence of soot below vocal cords suggests the victim was alive when the fire started.

Case 2: Information from Bones

• General skeletal characteristics (height, weight, build).
• Age (ossification centers).
• Sex (differences in skull and pelvis features).

Methods of Investigation

• -Anatomical examination, forensic anthropology and DNA testing, radiological examinations.

Case 3: Information for a Pathologist

• Medical history, tattoos, amputations healed fractures, prosthetic devices or surgical scars, occupational scars, any skeletal differences, and pregnancies.

Medico-legal Systems for Investigating Death

• If a death is natural and a doctor can sign a death certificate, the relatives can proceed with burial or cremation.
• If the death is not natural or if no doctor can complete a death certificate, the need for a death investigation system arises.

Legal Implications of Wounding and Head Injuries

• Punishments (e.g., prison terms) for grievous bodily harm and injuries to various parts of the body.
• Punishments and consideration are increased when it involves a child, spouse/ close relative/ witness.

Legal Implications, Wounding and Head Injuries (Specifics)

• Punishments for offences committed by means of explosives are higher
• Punishments for wounding, cutting, or pointed-instrument offenses can be higher or lowered based on intent and the outcome

Legal Implications, Health Care, and Death/Injury Investigation

• Details of cases where punishments may be lowered.
• Legal implications on investigations and related issues
• Processes if someone refuses to provide specimens or information.

Health Act

• Legislation regulates healthcare services in Malta, and covers patient rights and government health policies.
• This Act has departments for policy, regulations, and service delivery.

Council of Health

• Advise the government on matters concerning health in Malta, including matters related to patient rights.

Article 27 (Patient Rights)

• Patients' entitlement to healthcare.
• Right to information concerning health.
• Informed consent for treatment plan.
• Access to medical records.
• Right to refuse treatment (with restrictions).
• Prompt treatment and care.

Identification

• Methods available to identify individuals (e.g. fingerprints, dental records)

Investigation (Steps)

• Establish boundaries, access control, staging area, rest, rehab, interview area for site and evidence.

Medico-Legal Systems

• Systems/procedures for handling deaths (natural, or suspicious).
• Specificities of cases (e.g. prison, hospital deaths).

Legal Implications (Specifics)

• Details of cases where punishments are reduced due to mitigating circumstances
• Description of how medical or legal experts are used in specific investigations (e.g., injuries, death cases)

Medico Legal implication of wounding and head injuries

• Punishments for grievous bodily harm and related issues (cases and mitigations)

• Procedures for handling evidence related to violent injuries

• Legal implications related to injuries in some specific contexts (e.g. vehicular accidents)
