Dental Crazing
Definition
A network of fine surface fractures in tooth enamel produced by rapid heating and cooling. A characteristic fire-damage pattern that must be distinguished from antemortem enamel defects.
- Appearance
- Network of fine surface cracks in enamel
- Cause
- Rapid heating and cooling of the tooth
- Context
- Fire scene and burned-remains examination
- Must be distinguished from
- Antemortem enamel defects
Common questions
Why is distinguishing crazing from antemortem defects important?+
Antemortem enamel defects can suggest developmental conditions or prior dental history relevant to identification, while crazing is a postmortem artefact of heat exposure. Misreading crazing as an antemortem feature could produce a false exclusion when comparing to dental records.
Does dental crazing alone indicate cause of death?+
No. Crazing only indicates that the teeth were exposed to significant heat; it says nothing about whether the person was alive or dead at the time of the fire, which is assessed through other pathological findings.
