Bite marks are scientifically classified based on their characteristics, shape, and the type of tissue they are found on.
The types of bite marks commonly studied in forensic odontology:
1. Based on Cause
Human Bite Marks: Made by human teeth, often oval or circular in shape. They show distinctive tooth impressions, including incisor, canine, and molar marks.
Animal Bite Marks: Caused by animals, with varying patterns depending on the species (e.g., sharp canine punctures for carnivores, flat grinding marks for herbivores).
Self-Inflicted Bite Marks: Usually seen on accessible parts of the body, such as arms or hands, with signs of irregular pressure.
2. Based on Severity
Superficial Bite Marks: Minor impressions or abrasions on the skin, without breaking the surface.
Moderate Bite Marks: Deeper indentations with visible bruising or swelling, possibly including partial skin penetration.
Severe Bite Marks: Deep tissue damage, lacerations, or even avulsion (removal of tissue).
3. Based on Appearance
Clear Bite Marks: Well-defined marks with visible tooth impressions, often caused by firm pressure.
Obscured Bite Marks: Faint or partial impressions, often distorted due to movement or poor surface texture.
Diffuse Bite Marks: Blurred or smudged impressions with no clear tooth details, caused by sliding or excessive movement.
4. Based on Skin Reaction
Erythematous Bite Marks: Reddened skin due to irritation or inflammation.
Hemorrhagic Bite Marks: Bruises or blood leakage under the skin caused by strong pressure.
Abraded Bite Marks: Skin surface is scraped or scratched, showing signs of tearing.
Lacerated Bite Marks: Deep cuts or tears in the skin caused by excessive force.
5. Based on Anatomical Location
Occlusal Bite Marks: Found on hard surfaces such as cartilage or bone, with deep impressions of the biting edges of teeth.
Soft Tissue Bite Marks: Found on skin or other soft tissues, showing bruising or puncture patterns.
6. Based on Forensic Timing
Antemortem Bite Marks: Inflicted before death, often showing inflammation or healing reactions.
Perimortem Bite Marks: Occur around the time of death, with limited healing response but some skin elasticity.
Postmortem Bite Marks: Inflicted after death, appearing pale with no inflammatory response.
This classification system helps forensic experts analyze bite marks in crime investigations and medical scenarios systematically.
