Why are teeth important to forensics?
Teeth appear to be vital pieces of evidence in several such investigations. Teeth are preserved in the closed cavities of the mouth and are generally resistant to the threatening environmental conditions that may be associated with the death of an individual, making them very useful in postmortem analysis.
How accurate is dental identification?
The accuracy of the methodology was 75,4%, the sensitivity was 53,5% and the specificity was 86,4%. Overall, there was a tendency of the observers to overlook non-dental characteristics.
How do dental records work?
A forensic dentist can extract DNA from the pulp chamber to crossmatch and identify a victim. Investigators can examine dental records to match them to a corpse, or to match a bite mark to a perpetrator. A forensic dentist can utilize ameloglyphics, or enamel rod patterns.
How do I read a perio chart?
The Meanings of the Measurements
- 0-3mm without bleeding: Perfect!
- 1-3mm with bleeding: Early signs of gingivitis.
- 3-5mm with no bleeding: This is an indication that there is a potential for gum disease.
- 3-5mm with bleeding: This is an early stage of gum disease or the beginning of periodontitis.

Do teeth decompose after death?
After death however, teeth become the most durable part of the body, which explains why they are often found with ancient skeletons. “Teeth decay easily in life, but once death occurs it stops,” says Dr Lazer explaining that the bacteria that cause dental decay cannot survive after death. “Teeth tend to survive well.

Do old teeth have DNA?
Abstract. Teeth and bones are frequently the only sources of DNA available for identification of degraded or fragmented human remains. The unique composition of teeth and their location in the jawbone provide additional protection to DNA compared to bones making them a preferred source of DNA in many cases.
